Grundig, Simprop and Multiplex Conversions
It might be of interest for others, so I repost some of my conversions rom the last years maybe to give others some ideas and inspiration.
First is a Varioprop 10 in 35MHz. followed ba a Varioprop 12 in black (2.4G) and yellow (35MHz).
Cheers
Frank

Next is a Grundig TX 14, a very rare set converted to 35MHz.

One of the first proportional radios on the German market was the Simprop Digi4.
Converted to both 2.4G and 35MHz choosable by just flicking the power switch in the proper direction.
Separate trim pots. Cheers

Re: Grundig, Simprop and Multiplex Conversions
Also very rare and one of the early proportional sets was the Multiplex Digitron, here converted to 35MHz.
It has separate trim pots, so I add a small picture how I solved this proplem on the easy way. It works great. Frank

A very rare set was the Minitron f3. My best friend at school used to have this one 45 years ago. He sadly past away a long time ago.

Separate trim pots also.Frank

Re: Grundig, Simprop and Multiplex Conversions
All very nice Frank
I do have a soft spot for the European radios - the styling is so different to the American "utilitarian" box approach that many of us are used to

Re: Grundig, Simprop and Multiplex Conversions
Is the printed circuit board original? It could well be, because the manufacturers Schöning and Scheck had played around with it over and over again. Mine after remodeling:
Remarkable about the transmitter is its small size, and - in contrast - the original antenna is quite long, longer than your Multiplex Digitron's one. (I'll have a look tomorrow ;-) Absolutely not handy! With this TX the rubber antenna pleases (me) really much better than the original asparagus ;-)
Mr. Scheck has passed away, but Mr. Schöning you can see the elderly gentleman with the cap sitting behind the fence:
Also here the second from the left:

Hi Patrick,
the Veroboard is not original. I removed the original PCB and used this to have a platform for all the pots and the arduino. I still use the original long antenna on 35MHz to remind me of the good old times with my schoolmate Klaus-Dieter 45+ years ago.
Nice to see, that Mr. Schöning is still around, he would love to see, that some of his radios are still in use.

The Multiplex Digitron as handheld transmitter in use (well, that was only theater, even the corduroy hat ;-) Other things, too: http://www.rc-network.de/forum/showthre ... ost3787978
