SGC SG-705 SSB Radiotelephone (RARE)

Ill give you a few bucks for it !

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.

It looks cool, even if it didn't get used it makes a great talking piece. Would be sweet in the shack

Wow that's cool never seen one of those before

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

I have a ssb radiotelephone with crystals , larger size . If you want them , they are yours.

Take on the bowl. Lol

Amazing

Never knew about marine SSB. Interesting.

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🏃💨💨💨💨💨

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.

Use a dds vfo on it

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.

It looks cool if nothing else. ✌✌

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.

Seems pretty obvious but have you contacted SGC to see if they can provide info on this radio?

That's really cool on marine radio and be good for the boat captains out there in the ocean 🌊

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.

Are there any past employees out there who might have knowledge on this and the earlier military radios produced by SGC?
