<< my setup would only be on ssb with low power, and i think that with vfsk/dfcw using one second or less characters would give no problem. >> Agreed. It would probably work fine t
hello again RIK... you may not have seen a previous note to yourself concerning my reasoning for soundcard output on vfsk/dfcw/qrss. as i am in the USA, i don't have an LF allocation, but i surely co
[snip] So, if possible, stay above 2kHz, then you don't even need a sine wave. [snip] Well, if you use a perfect square wave, this requirement can be relaxed a bit, as a perfect square wave has only
Hi David, as far as I know 90% of all 136kHz transmitters used in Europe are straight CW transmitters with no possibility to modulate SSB. So the most easy (and efficient) way to get QRSS is just key
ok i get what you are saying....as i am in the US, i was interested in qrss and the other programs for use on 80m and 160m for lowpower ops and dx. so my setup would only be on ssb with low power, an
The problem with using a soundcard output to a mic input is not in the programming aspect, but is a question of efficiency and possibly power dissipation. Guys who key Class C, D, and E amplifiers ha
good info, but the questions beg to be asked...if audio tones can be used for afsk on all these digimodes, why not vfsk/dfcw/qrss etc. the audio is just audio. while i know that there is some small p
