Hello Lowfers.
This weekend stayed in the city and listened on 40m LW, 6m above ground. I prooved
again that this ant is insufficient, giving 40dB lesser signals than the one at the cottage.
If I want to listen at this QTH I must either build selective preamplifier or
make
loop ant again.
Tried many times (specially at full hours) to watch Spectrogram. No success.

I tuned across the whole band and heard DF2PY calling CQ in normal CW. I changed
Spectrogram settings and recorded him. Of course, it has no sense to record audible signals...
Getting QRV:
Having done PCB with tuned 1.36 MHz osc and another PCB with deviders and keyed
drivers (thanks G3YXM for his kind help). Only to put them into a box and add a final
stage with two IRF mosfets. If all goes well I could undertake first experiments with
TX (perhaps Slow-CW) during the following weekend. I will let you know.
