Where can I buy some attenuators to attenuate signals while Dfing?

Any good info or sources of info on the subject?

I'm going to try to do it with a HT and its S-meter.


Hi Thatcher,

The S-meter on most FM handhelds are miserable poor indicators,
basically useful only as "busy" indicators.

Connect your sniffer antenna to a detector circuit feeding a good
digital voltmeter, and put a 300 Ohm variable resistor ahead of the
detector. The "good" digital voltmeter doesn't even have to be that
good.
