As I recall about 1300 ohms with 39 mV full scale. Be sure to load the detector with 1300 ohms while making measurements because the meter movement is the bulk of the series resistance for the detector diode. 73, Tom W8JI w8ji@contesting.com -- FAQ on WWW: http://www.contesting.com/FAQ/amps Submissions: amps@contesting.com Administrative requests: amps-REQUEST@contesting.com Problems: owner-amps@contesting.com |
