Hello Alberto and Group, I have some ideas for a 'Slow-CW-Viewer' (some of them have been implemented in Spectrum Lab, others in Spectran, others not at all...) How about this : - adjustable 'color b

Hello Geri, Rik, and others, Concerning the PSK31-signal generated from DF0WD: Oh yes, the signal must have been a little "broad" because the transverter which I used at DF0WD was a bit overdriven an

Hello Andy, Steward and others, I also think that modifying the PSK generator with a 'slow phase change' as suggested by Steward (KK7KA) is a very good idea so we don't need linear transmitters / tra

Hello Alan and others, Thanks for the information about the "new" modulation of CFH (or, to be precise, the absence of a modulation). Last weekend I was amazed by the strong carrier on 137.04, and sp

Hello Dave, hello group, Yes, it was indeed OM2TW on 136.8. I also tried to call him, but got no reply - maybe my 80mW (from DF0WD) too weak this evening, also some static around later. Blew a FET in

Hello Mike and group, Firstly, the frequency stability - presumably of my IC-706 Mk1 - was not good enough for the 30s dot setting. After a long warm-up period, it settled down to a ragged line that

Hello group, Just did a few tests (off-air) using a slow variant of PSK31 which could be called PSK10, PSK05 etc. Instead of the signaling rate of 31.25 symbols/second from G3PLX's original PSK31, I

Well, the DCF77 decoder was a nice experiment, but not too much more than that. The problem is, PC clocks (though called 'Real Time Clocks') can be quite bad, much worse than the cheapest wristwatch
