Hi Dennis
The 19 set is a kit from Panzerwerk.com. They do lots of German radios, some with decals some without.
They are excellent kits.
I still have a 19set, I don't know whether it still works, it's been in store since I got rid of my workshop, several years ago.
It's a post wwII one (no B set) , but it is complete with all the leads and variometer. It is on a carrier, I cannot lift it on my own!!
Also got complete Mk1 38 set, no batteries, of course, but it works off a home made PSU.
I've Also got quite a bit of Clansman kit.
You might have guessed from the above that I am a radio amateur, I have been licensed since 1975, with the call G8KUZ.
I have bought the Futaba 7 channel radio control kit, from Arnortek, so that I can I can have a go at making a sound card, and play with some sound.
My last go with RC, was in the 1970's . A lot has changed since then!

I can't believe the amount of switches, and the thickness of the manual. I hope I don't have to do much programming to get it to work with the Firefly kit!
Regards
John
What is involved in converting the TX into single stick operation?
