Members of the K1USN Radio Club, who are also members of the CW Operators’ Club (CWops), run a one-hour slow speed CW “contest,” called the SST.
For those who prefer a more leisurely CW pace or are new CW operators or contesters, this just might be what you're looking for!

Announcing a 2nd weekly SST
We're very pleased to announce the addition of a second weekly 1 hour SST session starting Friday February 5th, at a time more suited for European Amateur Radio Operators: 20:00-21:00 UTC.

 The existing SST operating rules apply and the latest N1MM Logger+ SST UDC file can be used.  3830scores.com supports this 2nd SST which is now listed on the WA7BNM Contest Calendar.

This recent announcement from CWops President Stew, GW0ETF
 describes the new Friday SST event:

A New Slow Speed CW Contest for Europe

The K1USN Radio Club, in conjunction with CWops, are planning to expand their existing and popular weekly Slow Speed CW Contests, held on Mondays at 0000-0100 UTC, to include a second one for the benefit of budding European CW contesters. This will run from 2000-2100 UTC every Friday beginning on February 5th 2021 and will share the same rules and format; it will also be fully supported by the N1MM contest logger. There is no formal log submission; instead participants are encouraged to upload their QSO totals and scores to the 3830 reporting website - easy! See www.3830scores.com

These contests will be conducted at 20 wpm or less and are aimed at CWops Academy students and any other novice CW contesters who are not comfortable with normal contest speeds. Everyone is welcome to take part and is a great opportunity for established CW contesters to come on and help encourage our new ops. Please see www.k1usn.com/sst.html for rules, easy to follow instructions and lots more.

If you're new to CW contesting or are experienced and wish to help please join us if and when you can.

All about the SST
The CWops Club (CWops) promotes the art of CW for those who wish to expand and improve their on-the-air experiences. CWops’ CW Academy (CWA) program has produced thousands of successful graduates who have gone on to become every day CW operators. Hundreds of CWA grads have become CWops members after demonstrating their ability to understand and communicate in CW at speeds of 25 WPM and higher!

CWops’ three weekly 25 to 40+ WPM CWT sprints are exciting, stimulating and a great way to improve CW copying ability, operating skills, and propagation knowledge. The CWTs create bonds of friendship among CW-loving operators around the world.

For those just getting started in CW contesting and others who prefer a more leisurely pace, several members of both the K1USN radio Club and CWops have created a weekly one-hour slow speed CW contest, the SST. Please join us!

K1USN’s Slow Speed Test is designed to encourage and assist those who signed up for CWA to learn CW or to improve their CW skills but are not yet copying 25 WPM, and all others who feel like “taking it slow and easy” once per week both for their own pleasure and to help others out. CWops currently offers a total of nine “slow speed” CWT’s per year just after the three CWA graduations where all are encouraged to slow down to 20 WPM. Many CWA grads make contacts in those sessions, enjoying a well-earned rush of accomplishment. The SST will expand those opportunities for success to 52 weeks per year!

All of us old enough to remember our Novice days recall the rush of adrenalin and the sweaty grip on our J-38 (or Radio Shack) keys during our first CW QSOs. This is what it must feel like for the new CW operators we want to encourage.

The weekly slow speed SST is also for operators who participate in regular CWT sessions, but only as S & P (Search and Pounce) entrants. The weekly 20 WPM or slower SSTs can build their confidence to find open frequencies and begin calling CQ, first in the SSTs and then in the more crowded and frenetic full speed CWTs. Successfully crossing that CQing threshold is another real accomplishment!

We hope many SST participants become sufficiently comfortable with CW contesting to enjoy the regular higher speed CWT sessions, other big CW contests, and smaller local and regional QSO parties, using N1MM+ (or other) computer loggers, spotting networks, call history files, live online scoring, etc. But we welcome everybody to join in the SSTs whether high speed CW contesting is your goal or not, including new ops making their first attempts at completing a CW QSO. In addition to SST’s 20 WPM upper speed limit, we ask all to be patient, supportive, and willing to slow down further as necessary to assist another op in completing an SST QSO.

CWA recommends using electronic keyers and paddles, but if you are more comfortable with some other device, please feel free to join us in the SSTs using a straight key, cootie key, bug or paddles. Unlike high speed contests, where QSO rate is king and a CQing/“running” station expects only the required exchange and confirms a contact with simply “dit” or “R,” the SST will encourage sending brief friendly greetings to the other Op. Friendliness is part of taking it slow and easy!

So please join us in the SSTs! All you need is an HF radio, an antenna, and the desire to become, and assist others to become, better CW operators!

SST: Slow Speed [Con]Test:
  • Suggested SST exchange: Each station sends a first name and state, province, or DX country
  • Unlike the higher speed contests, where QSO rate is king and a CQing/”running” station expects only the required exchange and typically acknowledges a contact with simply “dit” or “R,” the SST will encourage including brief friendly greetings to the other Op.
  • Example SST exchange between operator K1RV (Pi) and operator N1DC (Rick):
Pi, K1RV sends:
Rick, N1DC replies with:
Pi, K1RV replies with:
Rick, N1DC replies with:
Pi, K1RV: replies with:
GE Pi Rick MA
fyi, CW abbreviations used above: CQ (Calling Any Station),
      GE (Good Evening), GL (Good Luck) and TU (Thank You).

  • For those who use the N1MM Logger+  program, we've created a K1USN SST UDC (User Defined Contest) file which supports the SST. 
  • NEW for 2021: Beginning January 2021, for consistency and to help those paper logging/scoring, we are simplifying the SST scoring. Details can be found in the SCORING section of the K1USN SST Rules
**Note** - The 2021 updated scoring requires that you install the NEW ‘K1USN SST’ UDC file available from the N1MM+ UDC website
Download the latest K1USN UDC file into this folder on your station computer:

Documents/N1MM Logger+/
UserDefined Contests/
    • download our instruction file to a convenient location of your choice (or example: Documents/) and follow to complete the UDC installation.
N1MM Logger+ provides some online instructions:
Installing and Upgrading N1MM Logger+
The N1MM Logger+ UDC instructions

NEW for 2021: Several screen shots using N1MM Logger+ with the new 2021 K1USN SST  UDC:

N1MM Data Entry Window
N1MM Log data
N1MM Score window
New for 2021: N1MM+ Logger Call History File
Based on numerous requests, we now have a call history file for N1MM+.
  • Have you ever wondered what the N1MM+ ‘Associated Files’ section is when setting up your SST Contest Log? One of the features is the ability to implement a ‘Call History Lookup File'.
  • The ‘Call History Lookup' is a feature that can be used to pre-fill the exchange during a contest to save typing, or to display user comments or notes for specific call-signs. 
  • To implement: In the N1MM+ ‘new log’ set up, click the ‘Associated Files’ tab and then click ‘Change’ in the ‘Call History Filename’ menu line. Click ‘Yes’ and you are all set. Note, this file is updated frequently. You should check it every time you set up your new weekly SST log file.
New for 2021: K1USN QSO Certificate
SST cetificate
A ‘K1USN SST QSO Certificate’ for those who work the ‘K1USN Special Event Station’ during the weekly SST will be available by request with proof/details of QSO
  • Please include call sign, email address, date/time and band of your QSO with K1USN when filling out the request. 
  • Certificates in Adobe PDFAdobe Icon format, will be emailed to the address provided.
