Sanwa Exerd Help!!!...Sorry to "Bang ON" about it

[Jarvis]

A friend and me have just got back into racing after a 17 year break. We are running B44.1's with Lrp Sphere speedo and KO servo and receiver (modern stuff).

Problem is that our almost 20 year old Sanwa Exerd's have been returned to us in just about mint condition. We really want to use them but have heard several things such as, the transmitter and receiver will only run on Sanwa crystals, that there is a crystal for the transmitter and one for the receiver and that they won't work the wrong way around and that we could make wiring changes both with the transmitter and the receiver to allow everything to work as it should?

We also read somewhere that there is more chance of 'knitting fog' than getting these transmitters working. I find this strange as I have seen people using Sanwa Gemini tx's with modern setups and i am sure the Exerd is basically a Gemini with more knobs!?!? Are there any other receivers that we could use to get up and running?

If anyone could shed any light on the situation i would greatly appreciate it.

Many thanks in advance.
