Icom R 100 SSB Help - UK Vintage Radio Repair and Restoration Discussion Forum

Evening All

I have recently aquired an Icom R 100 receiver, as standard this set does not have CW/SSB however the subject unit has been fitted with an additional board that I think may be the conversion board that was offered by Ray Withers Communications (I think) many years ago. The set works in all standard respects and my question is does anyone know/remember how to switch to SSB when this mod has been fitted.

Thanks in advance.

I used to have one of these receivers fitted with that mod and I'm trying to get my remaining two brain cells to remember which key it was. Aaaargh! Possibly the AFC/ANL one? I do remember that the mod was only marginally successful - the SSB audio was pretty quiet and you had to whack up the volume to hear it.

Thanks for your response, I tried Afc/Anl but no difference.
Of course the board or wiring may be faulty !.
Anything further from your brain cells ?

No, I've tired stirring them up but nothing is forthcoming. The 'net seems to have little on this.

I worked for Ray but cant even recall the mod board...sorry

I could be confusing the mod with that done on the FRG 9600, am I correct in saying that was an RW mod. I have seen this mod on other R100s in the distant past.
I could have a search through the vintage mags but that won't help with my problem as it won't help with the operation. Random thought as I type could it have been a Martin Lynch conversion.
