Hello Clive;
Check out the IV3PRK website- www.iv3prk.it under "receiving antennas" and
then the "rx ant. tests" tab.Luis has a circuit using a 1.843 crystal
oscillator. I use the same device without the tuned circuit, just hanging a 1
meter wire off the outputpin and it works fine for me, tweaking receiving
loops. However, you may need the tuned output circuit plus an amplifier if you
are working at 10 wavelengths. The only thing I added was a multivibrator
circuit to key the oscillator on and off to discern from any other possible
signals.

Hi, Can anyone recommend a stable low power signal source suitable for
tweaking RX antennas. I only need 160m and will only be used within say 10
wavelengths. Preferably something off the shelf. Thanks Clive GM3POI
