Have put out a request for info on the ex-Decca employees net. Suspect this is a Hifix transmitter module - OK for 2 MHz or so but not much else. Walter G3JKV.
Kjell, SM1LCA is looking for a Decca 1876 transmitter schematic. There are four SJ757 transistors in each PA module. Any information appreciated. thanks sm6pxj, Christer
