 TEST - MFJ-812B meter  
MFJ-812B VHF meter
I bought this new many years ago.
Looks good; one light scratch on the right side of the meter face and one on the left side of the case.
Selling because I bought a different meter and don't need this one now.
Seems to work well but selling as-is due to age.
$23 plus actual shipping cost via USPS Ground Advantage.
USPS money order or PayPal if you pay the fee.
