RufzXP screenshot showing how to set the trainer modeThis tutorial shows how to load a custom words file in RufzXP instead of the normal callsigns database.

  1. You must already have RufzXP installed in your PC and workable
  2. Run RufzXP
  3. Click on "Mode", then click on "Trainer" in the drop down menu
  4. Click again on "Mode", then click on "Settings", the "Trainer settings" window suddenly pops up
  5. In the "Trainer settings window" click on "Load callbase", a dialog window pops up to let you select the custom file that you want to load. It must be a plain text file with the ".txt" extension. You can find the custm files that I prepared for you here: Files for Rufzxp and CW Player
  6. Navigate in your folder structure until you find the custom file that you want to load and select it, then click on "Open" in the same dialog window; the dialog window disappears
  7. In the "Trainer settings" window, under "session length", you can enter the "Number of groups per attempt"; I would enter 50 or so; alternatively, you might prefer to use the timer
  8. In the top right part of the "Trainer settings" window, you can select the speed increment that you want: "Fixed" (no increment), "Incremental" (specify the percentage of speed increment in the field below) or "Variable", which is the standard mode for RufzXPRufzXP screenshot showing how to load a custom database
  9. In the "Trainer settings" window, bottom right part, click on "OK"
  10. In the RufzXP main window, start a new attempt as usual.

This is one of those tables that I start filling in one of those infrequent days when the good will is plentiful, and that I wish to update from time to time. I hope to fullfil my commitment…

Even earlier than in the US, someone in Italy thought to organize a slow speed CW contest. Mind that PC, electronic and automathic mechanical keying are not allowed! The prize for the overall first place is a vertical Begali key! I translated the rules from Italian with Google and revised the text a little, it should be enough understandable. I apologize but I have no time to revise it better. Therefore, I decline any responsability concernig the accuracy of the translation. In case of any issue, you can't cite my translation as reference for the contest rules. The only official rules are here: http://www.iv3ehh.it/public/regolamento%20cw%20qrs.pdf The official logging software is in Italian and is here: http://www.iv3ehh.it/win-cw-qrs.htm

Here you are my unofficial translation of the rules:

CW QRS CONTEST

PURPOSE

- encourage telegraphic radio activities and value CW,
- practice in contests,
- improve empathy between radio amateurs.

We hope that the CQ QRS CONTEST can become a gym for those approaching this type of activity. Also for this reason we have introduced the sub-categories YL, UNder 25, OVer 70 and SWL. Keep up to date on the news by following Morse Basic School on Facebook and subscribing to the Telegram group https://t.me/cw_qrs

Weekly CW Slow Speed [con]TestAnnouncing the New Slow Way to Go!

Inaugural session Monday, Sept 14, 2020 @ 0000 UTC, (Sunday, Sept 13 @ 8:00 PM EDT)

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 everyday 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.

Now, 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 are starting a weekly one-hour slow speed CW contest, the SST. Please join us!

K1USN’s new 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, as well as all others who feel like “taking it slow and easy” once per week both for their own pleasure and to help Others out.

ik1hge 8 el. 432 MHz Quagi

In a USB key that was laying since years in a drawer,I found some old pictures of both the design and the construction of the antenna that I described in the article: Quagi 8 elements 432MHz. I though  to publish some of them, may be because some are weird, maybe because some are useful and might help or to other U/VHF antenna homemakers.

Hope you'll aprreciate my effort...

RufzXP is a software package used in High Speed Telegraphy (HST) championships, very useful also to any radio amateur to practice the recognition of callsigns at increasing CW speed.

We are now talking about a very interesting mounting kit, cheap but, unfortunately, completely undocumented. There are a few web sites managed by smart radio amateurs that make up for the lack of information while, in my small way, I am publishing some pictures of my assembly, together with some personal comments. This Chinese kit does not suite well to new bees but, if you are quite skilled with SMD components soldering, you can build the amplifier even if you are not an RF electronics specialist.
