I'm working on a ART13 transmitter what is a French version build in 1957.It has the CDA-T crystal unit installed but the wiring in the ART13 for the crystal channel selection is different than I can find in the documentation
In the conversion manual to convert a ART13 to a ART13-B so it can use the CDA-T I read that there should be an extra switch wafer on the channel switch specially for the crystal channel selection. This switch wafer is not installed and it has never been in the past, all is original
I vaguely remember that I read somewhere that the crystal channels only could be used in the remote control installation. So perhaps the channel selection wiring is connected directly to the remote control box plug?
The VFO/Xtal relay in the ART13 does not operate and the VFO is not working at all but in XTAL mode I get signal from the CDA-T unit when I manually push the relay inside the CDA-T for the specific crystal channel. So the CDA-T unit is working
Anyone with experience on the ART-13 with CDA-T unit? Is there perhaps a later date ART13 version with different wiring for the CDA-T channel selection done only from the remote control box?
