[R-390] Dittmore- Freimuth 390-A - Information wanted

[Joachim Groeger]

Among the three 390s I own is a Dittmore-Freimuth, Serial# 55, Contract DAA=
B05-68-C-0040

It is unusual in that it has a five digit seven-segment LED frequency reado=
ut mounted in place of the mechanical V-R counter. The first two digits (te=
ns and unit Megahertz) are not driven by the electronic counter but appear =
to merely represent a voltage derived from a multi-turn potentiometer mecha=
nically coupled to the range switch. The counter is encapsulated in a small=
 metal box mounted directly to the front panel in the position normally occ=
upied by the V-R counter mechanism. The orginal black counter cover to the =
front panel has been retained.=20

The whole affair seems to have been purpose designed and has a professional=
 appearance.

I have heard rumours of a small batch of Dittmore-Freimuth receivers having=
 been fitted with electronic counters under a special order but have never =
seen a report of an actual sighting.

Anyone able to shed some light on this mystery, thank you very much in adva=
nce.
