Hi Alex,
I should be very pleased to transmit, for you to attempt QRSS reception...
I can also send some QRSS sigs if you like - but first, it would be a good
idea to chose a frequency that has low noise at your QTH. Preferred
frequencies here are between 135.8 - 135.9 kHz, and 137.6 - 137.8 kHz, but
this can be changed to suit your conditions.
Also, you wrote:
...Now I have simple LC VFO as master oscillator in my TX. I think that
frequency stability is not adequate for QRSS. Is it so?
I used a VFO for QRSS transmission at one time - for 3 second dots, it is
OK provided you check the frequency every few minutes. But for longer dot
periods, a crystal or synthesiser is probably essential. Obviously, the RX
must be stable as well.
I think you are the first and only LF station from your part of the world,
so it would certainly be good to try some tests - good luck!
