There is a funny thing about the Gonset twins...when you find them for sale, you rarely find the PS with the receiver or the Mod/PS with the transmitter. This has always been a bit of a mystery to me since especially the transmitter is a bit useless without the Mod/PS unless someone has the time to build one up. The receiver PS is not that critical.
I was lucky enough to find a receiver/PS combo at a recent hamfest for a bargain price and in mint condition. I grabbed it quickly since I hope to duplicate the twins mobile installation I had in my '58 Chevy back in the good old days. I am still looking for the transmitter/Mod/PS combo. I have had several chances to pick up the front end, but have never seen a PS/Mod since I sold mine years abo to go mobile SSB with a Swan 240. If anyone has the G-77 package and wants to sell it, please contact me direct. 73, John, W4AWM
