Re: [time-nuts] Hameg HM8125 Time/frequency Standard
You might try the UK agent who has been quite helpful on scope spares. [EMAIL PROTECTED] I can't remember the fellow's name now, but I bought several control knobs to refurb an HM1005 scope. He was very helpful though this adress is not the one on the back of the manuals!

Re: [time-nuts] Hameg HM8125 Time/frequency Standard
Hi Alan, Tried that, and downloaded the operating manual a while back. Tried your tip and looked at the German version, but no luck either. Thanks for the suggestion though.

Re: [time-nuts] Hameg HM8125 Time/frequency Standard
Hi Ian I dont know whether it works for that unit, but try the Hameg site. http://www.hameg.com/66.0.html There are "almost" complete manuals for all the units (well certainly the scopes!) You may find that there are no schematics in the English versionsdownload the German versions (which you may see are bigger files) and the are often schematics at the back of thesethe titles etc are also bilingual.

[time-nuts] Hameg HM8125 Time/frequency Standard
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.
