NJQRP Sniffer circuit question
I have collected parts to build a NJQRP sniffer http://www.njqrp.org/sniffer/index.html
I only have a 0-100uA meter, not a 0-200uA. Should I be concerned about this meter working with the circuit. Would it be worthwhile to modify R11 to limit current or place a resistor in parallel with the meter.
Thanks for any input,
I don't see one on the schematic and you might not need it, but you can add a 1or 2 K ohm adjustable resistor in series with R11 to adjust instrument sensitivity, or just collapse the whip if the meter pegs out. Check out the instruction manual.
