You are VERY fortunate to have an electronics parts store in your city. Here in St. Louis we had around 20 back in the early 80’s. That doesn’t include RS btw. Today we have NONE. It really hurt bad when Gateway Electronics closed. They had great surplus parts and supplies. But all across the nation, hardware electronics stores have closed.
Oil Rigs? Yet another use for a rig like this. Honestly I had no idea what this rig was used for, but when I saw SGC I had to have it, now I'm going down another radio related rabbit hole:) (Fun stuff) Not much information out on gear like this, I would not think there were a lot of rigs that sold, as this would have been such a small market niche. I saw somewhere they sold in the two thousand dollar range. Thanks for the comment. Cheers
Cool find! I agree, that meter is awesome. I always felt lucky to have an electronics supply store nearby. They had all kinds of vintage components-just about anything you could need-and even a resale table where I picked up a few radios over the years. Unfortunately, about six months ago, I went by and found the doors closed and the place completely cleared out. Such a shame! I heard it was due to slow sales, as more people are buying online these days. Now, sadly, I’ll have to do the same.
You could determine the correct frequency range, and then find the output of the crystal oscillator where it feeds into the associated mixer, and then feed a signal of appropriate frequency and level into that point from an external oscillator such as a modern synthesized signal generator. I did that with an old HF marine radio by adding a BNC connector on the rear of the radio and then worked out the math and used it along with an Instek AFG-2125 generator and the combo made for a nice and usable rig. I looked at the transmitter output at full power on a spectrum analyzer and it was clean. I kept the crystal oscillator intact also so that I could use crystals if desired and keep it original as well.
Hi there it looks like a marine radio is it vhf marine or hf marine radio in Australia we had a outback radio ssb l think it was a 100 watt transceiver audit was used for communications in the outback it was very expensive at the time and l think it could make telephone calls but not sure in the 1990s great video as always cheers
SGC QUIT MAKING radios shortly after the owner died however one of the employees purchased the company and focused on the manufacture of antenna couplers for the military. Have you tried their web site? I would hope that they might still have information as to the technicals of their radios.

I loved Gateway Electronics…you could get almost anything there. Our options for local are basically gone…totally sucks!! lol😊
Happy Holidays Boys 👋
Very rare to see the 705 today, Mr. Goral would be happy to see it working, they used some of those on oil rigs as emergency radios.

Always a good find in those five and dime joints, off the wall stuff galore. If there isn't an electronic dept in the store, retreat🏃💨💨💨💨💨

This sounds interesting, not sure if I can pull it off. I need to process. :)
It looks cool, even if it didn't get used it makes a great talking piece. Would be sweet in the shack
Never knew about marine SSB. Interesting.
They also made military communications gear for third world countries back in the 80’s.
It looks cool if nothing else. ✌✌
That's really cool on marine radio and be good for the boat captains out there in the ocean 🌊
Wow that's cool never seen one of those before
Amazing
Are there any past employees out there who might have knowledge on this and the earlier military radios produced by SGC?
Take on the bowl. Lol

I have a ssb radiotelephone with crystals , larger size . If you want them , they are yours.
I will let you know if I need one. Thanks for the offer.

Use a dds vfo on it
I wondered about that as well.
Ill give you a few bucks for it !
Seems pretty obvious but have you contacted SGC to see if they can provide info on this radio?
They out of business. Thanks Anywho and Merry Christmas
