Does anyone know how to install a tone encoder into an ICOM 729 transceiver? The UT-30 unit is no longer produced and I have had no luck finding a used one. I contacted ICOM and was politely told that there is no longer support for this transceiver and I was on my own to figure it out. They were not even kind enough to let me know where the contact points would be own the boards.

If anyone has an old UT-30 or knows where I might find one that would help as well.
