Question for those who may know off the top of their heads...

My Becker 4201 VHF has failed
I've got a good Dittel FSG 2T 
Can I swap out these radios using the existing power / data plug?

FWIW I have the pin schematic for the Becker and checked for 12v at the plug and there is 12v but not on the 2 pins that are specified.

Are these radio plugs wired to a common layout or not?
Or am I heading for a Avionics shop B/C I do not have the fine motor skills to re wire a plug
Thanks in advance!

Nick it looks like the FSG 2T uses a DB-15 connector, while the Becker uses a DB-25. Different plug size at the least.

Wiring diagrams are different.  Don't let the smoke out.

Contact Becker Avionics inc in Florida, they just fixed my 25 year old AR4201 in about a week.

Fix included repairs on the circuit boards, general tune up, and a lot of free new front panel components - all for under $400 including shipping.

Just my opinion ( after dealing with 3 different FSG-2T radios).  A "good FSG 2T" might be an oxymoron. The front multifunction switch  (push and turn) is very fragile. All 3 of mine went bad. I'd fix the Becker.

I'm of the same opinion about the FSG. Becker is a better radio. Just needs some lovin...
