Hello Finbar, I could hear you with very good signals the last 2 days, on tuesday you were 569 and yesterday 549. I called you several times, tuesday you seemed to have heard a part of my call as you
16 november : As expected the condx were very good. MM0ALM - 589 - heard EI0CF - 569 - heard OZ5N - 579 - heard OH1TN - 559 - heard IK5ZPV - 429 - heard OH1TN had by far the strongest signal I ever h

For test-puposes I needed a dummyload that could withstand 450W on 136kHz for some minutes. Having some 470 Ohm / 25 Watt wirewound resistors in the junkbox I put 9 of them in parallel and measured 5
I just got a new 'beta' version of QRS ready that supports FDK. Those who want to test it are requested to send me a mail (direct, not via reflector). 73, Rik ON7YD
What a weekend, never heard so many stations (27) in 2 days. First of all congrats to the GD-boys, they did put a real big signal in the air. Remarkable was the strong QSB on their signal, especially
My appologies to Steve for 'stealing' his FDK, it was not my intention. I got to term FDK (Frequency Difference Keying) via DF8ZR (see his webpage) and it seemed better suited to me than VCW (Visual
We're back safely, but totally exhausted due to a very exciting weekend and a 3am (later for the London contingent) arrival home last night. Dave, David & Graham : once again thanks for the marvelous

The formula for a single-turn loop I found in the 'Taschenbuch der Hochfrequenztechnik' is the same as Dave's. 73, Rik ON7YD I've been reading your Home Page and came across a formula for the radiati
Nice weather, so a lot of gardenwork to do and only limited time to be active on 136. Stations heard CW : G4GVC (559), DL3FDO (569), G6RO (539), PA0KDM (569), PA0BWL (569), PA0LEG (569), G3KEV (579),
I just finished the 'upgrade' of my VFO to frequency shift keying. Tonight (29 november) I will try to do some test transmissions in DFCW (Dual Frequency CW) between 20 and 21 UT on 137700Hz. Dotleng
Next weekend I will be QRV in DFCW (Dual Frequency CW), when I am in the shack I will call CQ each full and half hour on 137700Hz (+/- QRM). parameters : - 8Hz shift (highest frequency = 'dash', lowe
To increase the probability of a QSO if copy is difficult, I find that the following procedure works well: 1) start and end the first transmission(s) with 3 x 3 callsigns (e.g. N4ICK N4ICK N4ICK DE G
This weekend I worked DF6NM and DF8ZR in 2-way DFCW. The QSO with Marcus, DF6NM, over a 480km distance was probably the first ever 2-way DFCW QSO. This first QSO's have proven what was expected : a.
After consulting DF8ZR and DF6NM, who both are also active in DFCW, I would like to suggest a kind of temporary DFCW standard in order to enhance DFCW QSO's and avoid 'collisions' with other modes :
All of Rik's standards look useful to me, but it is also essential to specify in the standard that the dash should be the higher (or lower) frequency. This is especially important if KK and RR are to
I have new new beta version of QRS ready (2.03b). Main changes to version 2.02b are : 1. CW-characters BK (-...-.-) and CT (-.-.-) added to the characterlist 2. In DFCW mode can the tones for 'dash'
While visting Reino's web-page I noticed something very interesting : at http://gamma.nic.fi/~oh9ufo/136log.html you find a drawing of his antennasystem, including the TX/antenna matching, and he see
