When my father - who became a ham years after I did - passed away, I found an unstarted project (board + components), which I only re-discovered again years later.

The board is marked DK0TV-001, and uses three ICs (as marked on the silk layer) SO42P, TCA1047 and TAA611. Apparently it converts 30 MHz to 10.7 MHz using the SO42P (with a 40.7 MHz crystal), then demodulates and amplifies.

Looking over the internet DK0TV barely pops up, a little strange considering this seems to have been the club callsign of a german broadcast station (ZDF2?).

Even though this call/kit probably pre-dates the internet, I am somewhat saddened I could find so little, and somewhat intrigued what this kit was about. Anyone remembers this?

    $\begingroup$ Interesting, can you add a photo or two to your question? $\endgroup$ – Mike Waters Jan 4 at 18:43
  • $\begingroup$ Sounds like a transverter? Although most modern HF radios would be able to do both 10mhz and 30mhz without a transverter. $\endgroup$ – user10489 Jan 5 at 1:15
  • $\begingroup$ We can tell you a bit about the ICs as far as we can recognize them, but the whole thing will be more interesting if we have an overview of the device – ideally, a schematic, but assuming that'll be hard to come by ad-hoc, a picture of the board (from both sides!) would be good a start. $\endgroup$ – Marcus Müller Jan 5 at 14:41

    $\begingroup$ @MikeWaters, I've added a couple of images. Sorry for the delay - I didn't have access to the kit. $\endgroup$ – jcoppens Jan 7 at 14:32

    $\begingroup$ Why would a transverter from that era convert to 10.7MHz? That's a common IF frequency for receive but no one would have had a rig capable of transmitting on that frequency. I'd say it's a down converter of some sort, perhaps for satellites (the early OSCARs had downlinks on 29MHz) or maybe it's a UHF down converter (for fast scan TV)? $\endgroup$ – Duston Jan 7 at 15:14
