interested in modems for digital modes? Pse scroll down..


From time to time I'll add pictures of the modems on my shelf. Two of them you can "see" in the SO2R RTTY setup shown in the upper right corner on this page. There is a Tono Theta 777 sitting on an OMNI VI+ and a MFJ-1278 for the local Packet-Cluster.

But below I begin with some stuff I built quite a long time ago...

Here's a GLB Packet Radio Modem (sounded a bit like the bell of a moose). From abt 1985. Was a kind of counterpart to the TAPR TNCs developed by a Canadian group if I remember correctly:

That's a TNC2a. Was used as a gateway between HF and 2m/70cm:

Here's an early prototype of a PTC (Pactor Controller) that I built together with DL6MAA in 1990/1991. Yes, looks a bit jumbled but worked for many years. The front shows the LEDs of the first commercial PTC already:

The software version reads 1.0, 9. April 1991. Unfortunately the SMD type processor can't be seen, I'll have a look for some more pictures.
