1 Introduction

SKCC Skimmer is a program that helps find stations you have not yet worked in order to achieve various SKCC award levels (called GOALs) as well as stations that need you in order to achieve theirs (called TARGETs).
It runs on your local computer and uses data from five sources:
  • Real-time spots from the Reverse Beacon Network.
  • Your master ADI logfile of all SKCC contacts.
  • Member data from the skccgroup.com website.
  • The SKCC Sked Page.
  • The K7MJG RBN Retail Servers.

You supply your master SKCC log file and SKCC Skimmer will show you stations that match your goals and targets that are sending CQ -- right now. In addition, it will show you operators that are currently logged into the SKCC Sked page that match your goals and targets so that you can arrange for an on-air exchange.
Example: I'm currently an SKCC Senator (SX1) and want to advance to an SX2. I'm also a TX9 and would like to advance to a TX10 and a CX5 that would like to advance to a CX6. So I run SKCC Skimmer from the command line and specify my master SKCC log file, MasterLog.adi, as well as my goals (explained later) of CXn, TXn and SXn. I run SKCC Skimmer and it will display RBN spots as they come in.
This snippet is an example run. The output is explained after the snippet.

  • Lines 3-11: Informational progress lines as the tool collects necessary data. Note that operators that have achieved new levels are reported here with an FYI in advance of them becoming effective -- so you can get ready to nab them as soon as they are official.
  • Line 13: An indicator of what goals the SKCC Skimmer is using for this run.
  • Line 14: An indicator of the targets you've chosen for this run.
  • Line 15: An announcement about which bands to look for spots.
  • Lines 17-22: Information about the progress towards your specified goals.
  • Lines 24-25: Informational messages about awards for which you qualify but have yet to apply.
  • Lines 27-31: Information about which spotters are online and fall within your specified radius.
  • Lines 35-37: Operators that are logged in to the SKCC Sked page that match your goals and/or targets. (There may be more operators logged in, but these are the ones that match.) There is a lot of useful information on those lines, but particularly useful are the phrases "YOU need them for... and THEY need YOU for...".
  • Line 37: Note that NV4U has a prefix that you've never worked before, so you'll see the prefix goal indicator, in this case Px4, as well as how many additional points you'll get for working them. The word 'new' tells you that you've never worked that prefix before.
  • Line 40: Status message indicating that SKCC Skimmer has connected to one of K7MJG's RBN Retail Servers.
  • Lines 41 & 43: Progress dots so that you know that SKCC Skimmer is working even during long periods where no goal or target stations are spotted.
  • Lines 42 & 44-49: Stations spotted by the Reverse Beacon Network that either you need to work or those that need to work you. Note all the good things that happen by working N3WT.
  • Line 49: This is an example of a prefix hit where you've actually already worked a K7 station before, but K7EKY is newer by 592 points.

2 Features

  • Portable - Has been tested on:
    • Windows (ActiveState Python versions 2.7.8 and 3.4.1).
    • Mac (preinstalled Python version 2.7.6).
    • Raspberry Pi (preinstalled Python versions 2.7.3 and 3.2.3).
  • Finds stations that you need to work (GOALs) as well as stations that need to work you (TARGETs).
    • Displays stations spotted near your QTH.
    • Shows you stations that you have not yet worked based on your master SKCC ADI file.
    • Automatically Updates - While SKCC Skimmer is running, and as you work new stations and save them in your ADI logfile, SKCC Skimmer program detects that the logfile has changed and re-reads it so that you don't have to restart SKCC Skimmer after each contact.
    • Interactive mode allows you to lookup stations that you hear on the air and determine if you need to work them or they need to work you.
    • Able to exclude a list of specified stations. (W1AW, for example.)
    • Able to include a list of special 'friend' stations. (K3Y/0, for example.)
    • Displays the member number, name and SPC of each SKED Login and RBN spot.
    • Able to include or exclude specified bands.
    • Has a verbose option to display all unfiltered RBN spots.
    • Interactive mode allows you to lookup a call sign or member number. Useful if you hear someone on the air that is not calling CQ and they are also not on the SKED page.
  • Open Source - The source code is included under the MIT license. Feel free to modify it, especially for anything that will promote continued and expanded use of CW or the Reverse Beacon Network.

SKCC Rules of Etiquette:
  • Be polite. Not all operators that happen to have SKCC numbers are active SKCC operators. If they are spotted outside the range of the SKCC frequencies or it is obvious that they are not using a straight key, do not answer their CQ. (Unless of course they are calling 'CQ SKCC'.)
  • After tuning to a spotted frequency, always listen and confirm that the spotted station is actually calling CQ. Not all RBN spots are actual CQs -- it will often report the callsign of both parties during a QSO, not just the station that initially called CQ.
  • Do not inform someone of their SKCC number then ask them to pass it back to you.
  • Do not ask for someone's SKCC number if they have not freely provided it in response to yours.
Download version v7.0.3 for Windows here.
Download version v7.0.3 for all other platforms here.
Important note for the 'all other platforms version': The Skimmer's Python source code has a dependency on a package called 'requests'. To install it, you will need to either run 'pip install requests' or 'pip3 install requests' from a command line before the Skimmer will run. You can verify that it is installed by running 'pip list' and look for 'requests'.

      Feel free to fork the repository for your own needs. If they are generally useful changes, consider making a pull request.
  • 2015-05-12 - Version 3.5.1
    • Emergency bug fix related to non-utf8 characters being used in the status messages of SKED PAGE logins. Changed the decode of the side-bar to ignore illegal utf-8 sequences during decoding of the page content.
  • 2015-05-05 - Version 3.5
    • (beta) Added monthly brag tracking goal. Shows you spots and Sked page logins that you have not yet worked this month towards your monthly brag activity. Does not count QSOs worked during any Sprint and will not show you brag RBN spots during any Sprint.
    • Will now show you all spotters that have been online in the last 24 hours. In prior releases, SKCC Skimmer would only show you spotters that were currently online. This could cause you to see fewer spots as you run SKCC Skimmer for a long time because some spotters that were found at program startup could go offline as the program runs. Likewise, spotters that come online since you started the program would not be in the spotter list, so you would not see spots from that newly-online spotter. This change solves these issues.
  • 2015-04-22 - Version 3.0.1
    • Fixed a problem where an operator who has achieved their TX8 would be misidentified as TX8 before their effective date.
    • Now indicates the spotter radius value when searching for online RBN spotters.
  • 2015-04-22 - Version 3.0
    • Better Spotting. Nearby online spotters are now automatically determined based on your QTH, giving you better spots and less noise.
    • Notifications. All new spots and SKED logins can optionally generate a 'beep' so you can keep your SKCC Skimmer window in the background if you like.
    • Readability. A new display format will make spots easier to read.
    • Sked. Shows you the last spotted frequency for a SKED login.
    • Added 6m and 60m support.
    • More loggers. ADI file parsing algorithm has been rewritten, supporting output from more loggers.
    • Various bug fixes.
    • Removed SPOTTER_PREFIXES and SPOTTERS_NEARBY configuration items.
    • Added MY_GRIDSQUARE and SPOTTER_RADIUS configuration items.
    • Added a "bands" command line option.
    • Added a "maidenhead" command line option to specify QTH grid square.
    • Added a "radius" command line option to specify the spotter radius.
    • Added NOTIFICATION configuration item.
    • Added a "notification" command line option to turn beeping on or off.
    • Added a "logfile" command line option to allow overriding the corresponding setting in skcc_skimmer.cfg.
    • Got rid of the --lookup option. Use interactive mode instead.
  • 2015-04-10 - Version 2.0.5
    • Fixed a problem where ADI records were being ignored if the <EOR> indictor did not appear at the beginning of the line.
  • 2015-04-10 - Version 2.0.4
    • No longer requires you to install Python on Windows!

    • Changed shortcut name from skcc_skimmer.lnk to run skcc_skimmer.lnk.
    • Added shortcut called run skcc_skimmer interactive.lnk.
    • Long call signs from RBN were getting truncated.
  • 2015-04-09 - Version 2.0.2
    • Fixed an issue that would cause a crash if a contact in the ADI file had two slashes in it.
    • Fixed an issue that would cause the tool to over report for a goal of S.
    • Added a shortcut called edit configuration to allow you to launch the Windows Notepad application to edit the skcc_skimmer.cfg in one click.

    • Now GOAL-oriented. Simply specify your goal(s), such as 'C', 'T', 'S', 'CXN', 'TXN', 'SXN', 'WAS', 'WAS-C' and 'P' and SKCC Skimmer will find stations that you need automatically.
    • Introducing TARGETS. Lets you find stations that NEED YOU to achieve their goals.
    • Added a verbose option to display all unfiltered RBN spots.
    • Added a lookup option to see if you need an operator or they need you. Useful if they are not on the Sked page or calling CQ (which would be picked up by RBN).
    • Now connects to and uses RBN spots from the K7MJG-hosted RBN Retail Servers.
    • Displays a WPM alert if the operator is sending faster than a configurable threshold. (Likely using keyer.)
    • Added an interactive mode so that you can check if you need stations that you hear on the air. (Ones that are not calling CQ or are logged into the SKED Page.)
  • 2015-02-15 - Version 1.2
    • Can now optionally specify callsign (MY_CALLSIGN) in skcc_skimmer.cfg instead of on the command line.
    • Some modifications to work with Python 3.2.3 on Raspberry Pi.

4.1 Using the K3Y Goal

The K3Y goal allows you to maximize your station and band yield during the annual K3Y special event held during the month of January.
To enable the K3Y goal, simply add K3Y to your GOAL list in the skcc_skimmer.cfg file.
There are special considerations for both the user and the operator during the K3Y event that provides necessary information to skcc_skimmer.

4.1.1 User Considerations

When logging a K3Y contact, log the callsign of the actual operator and then include in the comment field the K3Y station designator, one of:

K3Y-OC
K3Y-SA
K3Y Station Designators
You can use either a '/' or a '-' as the separator for all of them. Other text may also be in the status.

4.1.2 Operator Considerations

As a K3Y operator, in order to be "seen" by skcc_skimmer from the SKCC sked page, you'll want to use the following pattern somewhere in your status. Examples:
1
2
3
4
5
6
K3Y/9 7.055.5
K3Y/9 7.055
K3Y/9 7055
K3Y/EU 14050
K3Y/7 AZ 7055
K3Y/0 7.055 QRV
K3Y Status Examples
What is important is that the station designator occur first and the frequency occur second somewhere in the status. If the frequency is not one of the above forms, skcc_skimmer will not be able to determine the band the station is currently working.
Ideally, the operator will supply only the station designator followed by the current operating frequency.

4.2 Command Line Options

Use these options from the command line.

4.2.1 adi

1
2
3
4
5

7
 
--adi <your-logfile>
 
or
 
-a <your-logfile>
 
'adi' command line option
Specifies a log file that contains all the SKCC contacts you've ever made since becoming a member.
This option, when specified, overrides the setting in the skcc_skimmer.cfg configuration file.

4.2.2 bands

1
2
3

7
 
--bands <comma-separated-bands>
 
or
 
-b <comma-separated-bands>
 
'bands' command line option
Overrides your skcc_skimmer.cfg BANDS configuration item.
Example:
Maybe you have one SKCC Skimmer running on all bands with notifications off (the -n off option) that you are actively watching. Then you run another SKCC Skimmer window with the -b 10,6 option to watch for 10m and 6m spots with notifications on (the -n on option) where the window is either minimized or behind other windows. This way, you didn't have to change your master skcc_skimmer.cfg.

4.2.3 brag-months

1
2
3
 
--brag-months <number-of-months-back>
 
'brag-months' command line option
Allows you to obtain a history of previous brag months. The history will be displayed at program startup.

--verbose
 
or
 
-v
 
'verbose' command line option
Allows you to override the VERBOSE setting in the skcc_skimmer.cfg configuration file. Verbose mode tells SKCC Skimmer to display the raw data received from the Reverse Beacon Network in addition to the filtered reports about your goals and targets.
When VERBOSE is enabled, PROGRESS_DOTS are automatically disabled.

5 Configuration

By editing the skcc_skimmer.cfg configuration file, you can customize how SKCC Skimmer filters RBN spots and Sked Page logins. The configurable items are described below.

5.1 MY_CALLSIGN

Set this to your callsign. Once you set it here, you won't need to specify it on the command line.
1
2
3
 
MY_CALLSIGN = 'X6XXX'
 
MY_CALLSIGN Example

5.2 ADI_FILE

This specifies the ADI file that contains a log of all SKCC stations that you've every worked. This file is only read by SKCC Skimmer, never written. It is intended to be your live, active ADI file. SKCC Skimmer will automatically re-read the contents of your ADI file when it changes. In other words, when you make a new contact and your logging program writes to it. Use any name you like. You can even use a full path including backslashes (\) in Windows pathnames. Note that the small 'r' before the string is important. Do not remove it.
1
2
3
 
ADI_FILE = r'MasterLog.adi'
 
ADI_FILE Example

5.3 MY_GRIDSQUARE

This should be set to the 6 character Grid Square of your QTH (or wherever you are operating from). You can find your Grid Square by going to the QRZ.com website and looking up your callsign. Go the Detail tab and look for "Grid Square". Enter this value in the MY_GRIDSQUARE configuration item (inside the quotation marks).
1
2
3
 
MY_GRIDSQUARE = 'DM33xh'
 
MY_GRIDSQUARE Example

5.4 SPOTTER_RADIUS

SKCC Skimmer will only report spots close to your QTH. This item specifies how close the spotter must be in order to be considered nearby.
1
2
3
 
SPOTTER_RADIUS = 800
 
SPOTTER_RADIUS Example
The perfect radius value will depend on your QTH and the density of surrounding spotters. For example, in Phoenix, there are not many nearby spotters, so a radius of about 800 miles will include only about 10 spotters. Whereas on the east coast, the same radius value yields more than 20 spotters. The spotters selected are displayed at startup so that you can see the effect of your radius value. You'll have to play with this value to strike the right balance for your QTH.

5.5 GOALS

SKCC Skimmer filters spots based on goals.
Goals tell SKCC Skimmer which SKCC award levels you're are trying to achieve so that it can display RBN spots for stations that YOU NEED in order to achieve those awards.
Targets tell SKCC Skimmer which SKCC award levels you are trying to help others achieve. SKCC Skimmer will show you RBN spots for stations that NEED YOU.
Valid GOAL designations:
  • K3Y - This goal helps you maximize your station and band yield during the K3Y special event held each January. (See details here.)
  • C - You are attempting to achieve Centurion status. If you are already a Centurion, this goal will have no effect.
  • T - You are attempting to achieve Tribune status. If you are already a Tribune, this goal will have no effect.
  • S - You are attempting to achieve Senator status. If you are already a Senator, this goal will have no effect.
  • CXN - You are attempting to achieve an advanced C award level. That is, Cx2, Cx3, etc., all the way up to Cx10.
  • TXN - You are attempting to achieve an advanced T award level. That is, Tx2, Tx3, etc., all the way up to Tx10.
  • SXN - You are attempting to achieve an advanced S award level. That is, Sx2, Sx3, etc., all the way up to Sx10.
  • P - The prefix award promotes contacting new members — the newer the better. For example. Let's say you've worked a member with prefix AA4 whose member number is 5000, so you now have 5000 prefix points. Then, let's say you later work another AA4 station whose member number is 12000. The higher member number now replaces the older station in your total prefix point count, so now you have 12000 total prefix points. SKCC Skimmer will show you stations that will advance your prefix point count; either because it's a brand new prefix for you, or because that station has a higher member number than any member with that prefix that you've worked in the past.
    Examples of spots that include prefix hits:

    Prefix spot examples
    Note the prefix notation Px4(new +10671) on line 5. SKCC Skimmer will tell you that you need a station in order to advance your prefix point count. SKCC Skimmer will also tell you whether this is a new prefix for you by displaying the word new. If it's not new, then you have worked a station with that prefix before but working this particular station will increase your point count by the indicated amount.
  • WAS - You are attempting to achieve the SKCC Worked All States award. SKCC Skimmer will show you spotted stations in states that you need to work towards that goal.
  • WAS-C - You are attempting to achieve the SKCC Centurion Worked All States award. SKCC Skimmer will show you spotted stations in states that you need to work towards that goal.
  • BRAG - Shows you spots and Sked page logins that you have not yet worked this month towards your monthly brag activity. Does not count QSOs worked during any Sprint and will not show you brag RBN spots during any Sprint.
  • ALL - Enables all of the above.
  • NONE - Turns off all goals.
Multiple goals are specified comma separated.

5.6 TARGETS

SKCC Skimmer filters spots based on targets.
Goals tell SKCC Skimmer which SKCC award levels you're are trying to achieve so that it can display RBN spots for stations that YOU NEED in order to achieve those awards.
Targets tell SKCC Skimmer which SKCC award levels you are trying to help others achieve. SKCC Skimmer will show you RBN spots for stations that NEED YOU.
Valid TARGET designations:
  • C - You are wanting to help others achieve their Centurion status.
  • T - You are wanting to help others achieve their Tribune status.
  • S - You are wanting to help others achieve their Senator status.
  • CXN - You are wanting to help others achieve an advanced C award level. That is, Cx2, Cx3, etc., all the way up to Cx10.
  • TXN - You are wanting to help others achieve an advanced T award level. That is, Tx2, Tx3, etc., all the way up to Tx10.
  • SXN - You are wanting to help others achieve an advanced S award level. That is, Sx2, Sx3, etc., all the way up to Sx10.
  • ALL - Enables all of the above.
  • NONE - Turns off all targets.

5.7 BANDS

Specifies which bands to monitor. Possible values are: 160, 80, 60, 40, 30, 20, 17, 15, 12, 10 and 6. There is a commented out template line below the actual configuration line to assist and remind you of all bands. Spaces are okay in your configuration in order for it to line up with the template.

5.8 BRAG_MONTHS

Optional. Commands SKCC Skimmer to display a history of brag results at program startup. An arbitrary number of months can be specified. Can be overridden from the command line with the --brag-months option.
1
2
3
 
BRAG_MONTHS = 36
 
BRAG_MONTHS Example

5.9 SPOT_PERSISTENCE_MINUTES

When an operator is logged in to the SKCC Sked Page and then also issues a CQ that is spotted nearby, SKCC Skimmer will display a "last spotted" message indicating on what frequency the operator was last spotted and how long ago. SPOT_PERSISTENCE_MINUTES indicates how long that "last spotted" message persists before being removed.
If SPOT_PERSISTENCE_MINUTES is not specified in the configuration file, the default is 15 minutes.
1
2
3
 
SPOT_PERSISTENCE_MINUTES = 10
 
SPOT_PERSISTENCE_MINUTES Example

5.10 EXCLUSIONS

A space separated list of callsigns to ignore. Good for specifying beacons, for example.
EXCLUSIONS overrides FRIENDS.
1
2
3
 
EXCLUSIONS = 'W1AW'
 
EXCLUSIONS Example

5.11 FRIENDS

A space separated list of callsigns that are "friends" that have some special significance. If the spotted callsign is in this list of friends, then the spot will be displayed.
1
2
3
 
FRIENDS = 'K3Y/0'
 
FRIENDS Example
One member, a Senator, reports that they use the FRIENDS configuration to list all existing Senators so that they can work the unofficial "Worked All Senators" award.

5.12 PROGRESS_DOTS

If your criteria are very selective or you have worked a lot of stations, you may have long periods of time with no output. By enabling this option, you can specify how many progress dots are displayed. If the option is disabled, then no progress dots will be displayed.
  • ENABLED - True if you want to see progress dots, False if you don't.
  • DISPLAY_SECONDS - The number of seconds of silence before a progress dot is generated.
  • DOTS_PER_LINE - Rather than having dots wrap around at the edge of the screen, you can control how many dots are displayed on a line before a new line is generated.

PROGRESS_DOTS Example

5.13 SKED

When enabled, SKCC Skimmer will read the sidebar of the SKCC Sked web page and display members that are logged in that match your GOALS or TARGETS.
  • ENABLED - True if you want to enable reading the sidebar, False otherwise.
  • CHECK_SECONDS - How many seconds to wait before reading the sidebar again.

SKED Example
If a member that matches your goals or targets logs into the Sked page, SKCC Skimmer will display a plus sign (+) before their call sign.

5.14 LOG_FILE

Specifies whether you want each matching spot to be written to a log file. Because this file can accumulate over many sessions and multiple days, the date is also included on each line.
  • ENABLED - True to create a logfile, otherwise False.
  • FILE_NAME - The name of the log file.
  • DELETE_ON_STARTUP - True if you want the log file to be created fresh for each run. Otherwise set it to False.

5.15 HIGH_WPM

This item allows you to decide whether you see spots regarding stations that are likely not on a straight key or are otherwise sending faster than you know you can copy.
  • ACTION - What action to take when a spot has a WPM value above THRESHOLD.
    • suppress - Do not display the spot if it is HIGH_WPM.
    • warn - Display a warning if the WPM is at or above THRESHOLD.
    • always-display - Display the spot including the WPM value.

5.16 OFF_FREQUENCY

This indicates what to do when a member spot is not on an SKCC frequency.
  • ACTION - What action to take when a spot is outside an SKCC frequency range but is otherwise a good member spot.
    • suppress - Do not display the spot if it is outside of an SKCC frequency range.
    • warn - Display a warning if the spot is off frequency.
  • TOLERANCE - Specifies how many kHz above or below an SKCC frequency midpoint is considered off frequency.

OFF_FREQUENCY = {
'ACTION': 'suppress', # Valid values: 'suppress', 'warn'
'TOLERANCE': 10, # +/- kHz
}
 
OFF_FREQUENCY Example

5.17 NOTIFICATION

This section controls audible notification of new spots.
  • ENABLED - True to enable audible notifications, False otherwise.
  • CONDITION - When to beep. Valid values:
    • 'goals' - Beep if a spot matches one or more of your goals.
    • 'targets' - Beep if a spot matches one or more of your targets.
    • 'friends' - Beep if a spot matches a friend.
    These conditions can be combined, comma separated. E.g. 'goals,friends', which is the default.
  • RENOTIFICATION_DELAY_SECONDS - Once you are notified of a spotted callsign, you will not be notified again - for that callsign - for this amount of time. In other words, there is a timer per callsign.
Beeps will only occur when something new comes along, whether it be a new person that matches your goals or targets logging into the Sked Page, or, similarly, someone being spotted by RBN. Make sure that your Windows "default beep" is set to something other than 'none' and that you have your speakers unmuted and volume up. You can test your sounds by going to the Windows 'control panel', 'sounds' tab of the 'sound' form.

6 Awards Chart

This spreadsheet might help you understand the SKCC awards requirements in order to achieve the Senator award level:

7 Important Notes

7.1 CQ'ing

It is important to realize that this whole system only works if other members are calling CQ, so make sure to mix it up, say, 50% CQ'ing, 50% S&P (skim and pounce).
Look at it this way, if this program is widely adopted, then your CQ is less likely to go unanswered. Everybody wins.

7.2 Changing the Window Font Size

If you find the font size hard to read, this YouTube video explains how to change it. It also touches briefly on how to change your layout. That is, the width and height of your window.

7.3 Reverse Beacon Network

The folks at the Reverse Beacon Network do not intend for end users to connect to their raw data feed. Instead, they suggest that only "RBN Retail Servers" connect to the raw data feed and that end-users should connect to these Retail Servers. This lightens the load on the RBN servers considerably.
Accordingly, K7MJG has built a system of RBN Retail Servers in Python, hosted on a Digital Ocean cloud server, that can service hundreds of SKCC Skimmer users. When you run SKCC Skimmer, it attempts to connect to one of these servers. If there is a problem connecting to one of those servers, SKCC Skimmer will failover and connect directly to one of the three RBN servers (randomly selected).

7.4 Known Issues

  • "Count Discrepancies" -- The SKCC group has over 16,000 members. Over time, some operators that joined a long time ago have decided that they no longer wish to be contacted by SKCC members, so they have requested that their names be removed from the public database. The SKCC Skimmer program uses this public database. However, for the purposes of accurate award recognition, a private database is used by the official awards application programs (like AC2C's logger) that still contains these old callsigns.
    Therefore, if you've worked some of these now-deleted callsigns, the Skimmer will undercount the number of contacts required for a particular goal.
  • Centurion and Tribune have a second tier of awards (the Cx15, Cx20, Cx25... and Tx15, Tx20, Tx25... for example). Tracking of these award levels is not implemented. Additionally, the first tier of Centurion and Tribune award levels should stop at 10 (Cx10 and Tx10), however SKCC Skimmer will continue to show you spots for non-existent Cx11 and Tx11 awards.
    If this is annoying to you, you can simply not specify CXN or TXN as goals. Or, if you are attempting to achieve these higher level awards and SKCC Skimmer says that you need a station for your Tx11, Tx12, etc., know that you do indeed need to work them for the advanced award, it's just not displaying the information in the proper increments.

7.5 Dependencies

  • SKCC Skimmer depends on five Internet-based resources for its data:
    • The SKCC website, www.skccgroup.com.
    • The Reverse Beacon Network website, www.reversebeacon.net.
    • The Reverse Beacon Network telnet servers, telnet.reversebeacon.net, arcluster.reversebeacon.net and relay2.reversebeacon.net.
    • The K7MJG telnet servers.
    • The SKCC Sked page, sked.skccgroup.com.
    If any of these resources are unavailable, SKCC Skimmer will likely hang at startup. Try again once the dependent website is back up.
    Additionally, if the format of the data provided by any of these websites ever changes, SKCC Skimmer will not be able to function and will need to be revised to recognize the new format.
