Imho adding the transistor I mentioned could work. You also need a 
battery. A 1.5V single cell should be enough. My detector circuit was 
'breadboarded' at the time so I don't know about the case.

But the whole device could become very fancy by using a log 
converter/rectifier from Analog Devices. This would need 5V @<10mA and 
do the whole job, also being able to drive the meter directly, and it 
would read in dB, no less. That an a tiny NIST dipole on a 'stalk' would 
be a nice meter to have imho. Does anyone sell the relevant Analog 
logamps in ones ?
