Hello, Does anyone have a copy of a schematic or service manual for the down-converter for the Hameg HM8125 GPS frequency/time receiver?
The receiver and display seems to be working fine, but the separate down-converter appears to have been modified with a capacitor blocking the DC power feed from the receiver and what may be a voltage regulator has been removed. The downconverter appears to do more than just shift frequency, as it has a TDA 1574 FM subsystem chip in it as well as the expected RF circuitry. Any help would be appreciated, or even if someone had a spare downconverter for sale.........? These units do unfortunately, appear to be as scarce as hens' teeth. Thanks in advance, Ian Sheffield _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
