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. Ones 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. 73! Petr, OK1FIG
