OldTech,
If you never do another thing worthwhile in your time here on Earth, you are still WAY ahead of most of us. I salute you, sir.

i must agree 100%OldTech,

I read that in a quick Net search of the brand and model. My KRACO 8-track the same.
I was guessing 1976, but ‘75 is consistent with that (name escapes me) first digital read wristwatch.
Found an advertisement for a non-digital predecessor. 1974. $189. I extrapolated $200 for the GT-7C (WIN: “Whip Inflation Now”) which one online calculator placed at $1,000 in 2018 currency.
That puts a quality radio in perspective (for me). The ballpark range.
I was telling Larry I would eventually be interested in a radio that was very good on 11-meter, but without spurious emissions issues. Quality. He pointed to a (Yaesu, Alinco, don’t remember) at $1,300 and outlined features.
I’ve got about that much into the “portable base station” (including 25’ of ANCOR 6/2-Duplex at $5.99/ft as clean power leads yet to buy; etc) so it stopped me.
Then I did the calc.
Okay. There are radios above and below that, but $1k makes sense.
The Robyn gives off quality in every facet: Appearance. Feel of controls. Apparent sensitivity & receive. Audio quality is excellent. There’s nothing not to like, overall.
So I’m pleased to give it a home, and it’s already worked a little magic.

I feel I’ve done some nice things, but that is humbling, sir.
It’s a Christmas gift to every man hears it. That vet had a new birth.
(“Hey, j’hear Santa Claus posts on Worldwide DX!?”)
I really didn’t have time to find out what all was what on the Robyn.
VFO I’ve heard of.
BFO is terra incognita. (?)
BFO, or Beat Frequency Oscillator is a feature that puts a carrier into your receiver.
Originally used to turn a ham's on/off CW transmit carrier into a tone, by mixing the two carriers together in your receiver. And that's what makes a sideband receiver different. It replaces the carrier that was left out of your SSB transmit signal. That way it sounds like someone talking, instead of Donald Duck with his hand over his mouth.
A sideband radio uses the same oscillator to feed a carrier into the receiver that it uses to generate your SSB signal before converting it up to your channel frequency.
Adding a BFO to AM-only CB radios would sorta let you eavesdrop on sideband operators, but it was less effective than a receiver built to hear sideband properly.
I suppose it was the "Sound Tracker" of 1975. Cute, but not all that useful.

Thanks. I now “remember “ it from Dad talking about the switch on an ADF (automatic direction finder) after a brief online search in avionics. (I see VFO and the brain first goes to VFR).
(I keep telling myself I ain’t gonna sink too deep into this, but one boot is stuck in the muck and coming off)
Growing up in Dallas there were just a few too many guys with WWII experience in what we now call careers in telecom. Or electronic warfare. Both my Scout leaders, for example, were with Texas Instruments.
Rode over to Addison Airport in 1972 where Air Force One (26000?) was at Collins Radio prior to (surprise) announcement of Nixon’s trip to China.
Getting a 707 in and out of that airport is a job in efficient piloting.
Hung on the chain link fence at the roadside sidewalk where it was a few feet away. One AF guard. First trip to Dallas for one of those birds since 11/1963, IIRC.
Last I knew they are sent to E-Systems at Greenville, TX. The NOTAM for that period is seriously impressive.

WE have 707 -, 26000 here in Seattle at the Boeing Museum of Flight. You can hop in and walk through it!
Great stories from that ol' plane!
Mike is Honest as the day is long. I have personally known him working on CB's since 1976 in Fort Worth at Henshaw's Electronics off Belknap st. He's an expert but don't take him the SMT stuff.
I have heard of Larrys from a old Ham operator that I know...took the 50+ mile trip to McKenny..it was well worth my time! Fixed up a old cobra 142 gtx and wired back up the old D-104 for next to nothing! Nice Guy who knows what Hes Doing! Hes My Tech!
Wish me luck. I may have time to (ahem) visit Larry’s CB after loading a little ways away today.
That'll be sort of like karmic recompense for dragging a 53’ thru suburban north Dallas, right? (It’s not like I have cash burning a hole in my pocket, oh, no).
