RE: [AMRadio](still selling stuff!
Well to be honest I never saw the inside of one but a friend of mine had one, at least I think that is what he had. Now I'm not sure. Was there another model XCVR by Gonset that was similar but had low level modulation? I did have a silver faced G-7--- something, mobile XMTR with separate power supply / modulator where the modulators were triode connected zero biased as you described. Was it a G-77? I just can't remember but it was not a XCVR, just a XMTR. I think it had a 6146 in the final and the modulators were 6DQ6s. The receiver I used was PMR7 Multi ELMAC. God, those were the good old days!

It uses two 6dq6 tubes as modulators, modulating a 6dq5. What you might remember is the modulator tubes use the screen grid or protection grid, not the regular control grid for audio drive, and are set up as zero bias triodes A very neat little rig.

I am still cleaning out stuff I don't seem to use that has filled up the basement. Gonset G76 with home built power supply (looks very nice). This is a trans/receiver, sort of a receiver and transmitter in one small and really cool looking cabinet. 80 through 6 meters, VFO, plate modulated, puts out about 70 watts of carrier. __ AMRadio mailing list Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net __ AMRadio mailing list Home: http://mailman.qth.net/mailman/listinfo/amradio Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net
[AMRadio] Gonset
Hello John, You're right - the transmitter is a model G-77. The receiver was a model G-66. The final was a 6146, and it had a separate ps/modulator with two 6BQ6 class B modulators. 73, Bruce WA8TNC == John Coleman ARS WA5BXO wrote: Well to be honest I never saw the inside of one but a friend of mine had one, at least I think that is what he had.

[AMRadio] Low Level Modulation in Gonsets
You're probably thinking about the Communicator series, or the G28 or G50. These rigs used a different modulation scheme. Mike Duke, K5XU American Council of Blind Radio Amateurs
Re: [AMRadio] Low Level Modulation in Gonsets
you guys got me thinking i think i have a G 76? with power supply and speaker stored in the shop. got it from W4BB sk. years ago. 160-6 i think hummm wonder if i could hook it up the the old thunderbolt and get on AM . i remember only think wrong with it was where Morgan use to put his fingers on the top of the case and tune with his thumb paint has flacked off. sounds like a new project to start on. 73 Tony Anthony W.

Re: [AMRadio] Gonset
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
RE: [AMRadio] Low Level Modulation in Gonsets
The G76 was 80 through 6 meters, you needed to use a crystal on 6 meters, but it has a vfo for 80-10. The vfo seems stable, but it's a bit touchy to tune as its got a little knob. The transmitter (and receiver) audio is somewhat poor stock, but can be improved a bit with the usual tweaks. I got it as good as its likely to get without serious tube and iron changes, and there is no room for other iron. The transceiver is quite small, about the size of a shoe box. I used to have 2 of them, and they seem indestructible, swr? who cares, rough handling? who cares! We used to use one as the night before the hamfest campout rig. Throw some wire into the trees and talk! The receiver is quite good, it uses a 262Khz IF, and has parts on the IF cans to tailor the bandwidth, resistors across the primary and secondaries, and a small cap from primary to secondary. increasing the resistance of the resistors increases the Q, and vice versa, and the cap adjusts the nose of the passband. You can play with values to get it like you like, I have it set a bit more narrow than stock I think. Backlit receiver dial and meter, the rig looks very sharp.
