K7AGE builds KB3VZL's Field Strength Meter

A neat little project...



Summary:
"I follow Richard's, KB3VZL, February 2015 QST (page 71) article about building a field strength meter into a DVM. He built the circuit to fit inside a Harbor Freight digital volt meter. You can get these free at Harbor Freight if you have the right coupons.

I also use my new ISO-TIP battery powered soldering iron.

Three capacitors, two diodes and a pot is all that is needed. Build this on a small perf board and it fits easily inside the meter. 
Parts:
0.05 uF Cap
470 pF Cap
0.01 Cap
1N34 Diodes, you need 2
50K trim pot
hunk of perf board
switch
connector for antenna"
