I found a complete all original one at a flea market about 30 years ago for 5 bucks. Still in my shop on the shelf in working condition.

Very neat radio!

Hi, I'm developing a game where a military outpost has been stationed in the middle of a jungle to explore a meteorite hole. It's during the 80's. Is it okay if I extract some sound effects from this video to use?

Good job

Odd that a previous owner decided to strip out the 20/100 KC calibration oscillator from the upper deck. It's not like more space was needed for the AC power supply.

As an electronics tech working for the Government, I worked on all that equipment for many years. I was lucky enough to receive a modem like the one show. Today though with all the digital equipment we have, That equipment is old school now.

Sound is good through good design and the well designed bandwidth. BTW did you sell it?

Audion detector sounding like a charm, no superhet whistles, stations appear like from nowhere.

I do realise that the background noise is there for a reason, but I feel that if it was "a bit further in the background" we would be able to hear your narrative... Very interesting set btw 😊

How do I get in on this fun?

Amazing

I have a museum quality KWM-2A with power supply and speaker that I got at an estate sale from a good gentleman, SK. It has military contract numbers on it and apparently never used. The 5U4 and 5R4 and even the fuse holder was in a plastic bag. I use it with the 30S-1. Love it... I was asked the other day what was my "daily radio" and I told them it was this one. I have an iCom 7300 but nothing is like my Collins equipment. I can repair it as required. Some of my Collins equipment goes back to the 30K-1 made in 1947. It had been changed, before I got it in 1975 but the power supply components, even the capacitors, are original and I use it. I turned the 30K-1 into an RF amplifier project shortly after getting it and it has run a pair of 4-400A, 3-400Z, 3-1000Z and 4CX1000A projects. Love that Collins equipment. Thanks for posting. 73 WA4QGA El Paso

I had one of those. Once the insulation on the internal wiring crumbled beyond hope I sold it.

Well designed magic eye and all tubes too shielded by shield canes and dial spread impressive matching all for air craft standard quality level of accuracy good for users design and National and international use as a model too even to day Marconi radio testing instruments are unparalleled in sophisticated design for universal radio signal Generator with all provisions of calibrated AF signals and mode of modulation choice,shine and quality excellent 👍

This what I had as an emergency radio at Casey Base in Antarctica in 1979. It also had an add-on 2Kw linear PA if necessary. I used it as my ham transceiver to ensure it was always in working order. Used a 20 metre 2 element yagi mostly bare back for schedule with Australia. Also used a rhombic with segment lengths of about 400 metres which put out a whopping signal. I was VK0BC then, now VK4BAC. Unit worked flawlessly.

ОООО! Вери найз!!!!!!!!!!

What is the meter to the right ? There is a video here about Donald Pleasance the actor.. as he was a radioman in a Lancaster..shot down over France and captured in WW2. Vid shows a radioman working this unit.

I used to have a Dovetron!!! It was GIVEN to me. Had been modified for I think TTL output rather than loop. It got smoke damaged in a fire and I tossed it. I WISH I HAD KEPT IT!! I am 75. Got my intro to RTTY at the amateur club at Treasure Island, K6NCG, 68-69, look it up. The club had some 15 gear, and a friend and I went up to the mothball fleet and obtained some 28 stuff and a URA8. If you search K6NCG there are 3 distinct websites, photos of some of that.

Cb'rs and some Lid who was too lazy to actually call cq on an open frequency and make his own qso.

Thanks for the nice video Ray. Looks like it was pretty rainy there. de W4OSS

Good Job.

Hi Ray! I recently acquired a very nice Navy MAK radio myself. I have been endlessly searching for the TECHNICAL MANUAL FOR NAVY MODELS M0-1 and MAK Radio Telephone and Telegraph Transmitting and Receiving Equipment...no such luck. I was able to find a schematic which is unreadable online....with that said, do you have a source for a decent schematic or TM? Since looking at your video-I have also collected a Heathkit HP-13 PSU that I will be recapping. I am competent to do cosmetic restoration but am just getting into electronic repairs....I carry an amateur license and have some very competent HAM friends...the first quest is a Schematic. Can you point me to where I can find the necessary documentation? All the best! David

The name "PCR" is supposed to mean "Portable Communications Receiver" - so I guess this was based on a different definition of "portable" than the one I'm familiar with.

Thanks Ray, I always enjoy watching videos of events I'm unable to attend.

We had to type 60 wpm with no more than 3 critical mistakes in order to get out of basic comms school back in 1973.

Nice video, Ray! Keep up the LRRP

Where do find that old equipment? I can’t find anyone that does RTTY. Some did but got out of it 30 plus years ago. The older guy don’t remember it. Lol

Strange radio.

Torn E.b means: Tornister Empfänger Modell b (backpack receiver model b).

Nice. I've not seen one of these before. Why is it so big compared to a 19 Set? I thought the top part would be a power supply only. G4GHB.

I have just been gifted one of these sets in an unknown condition, if I can resurrect it, it will fill a gap in my ever growing collection of "boat anchors". Yours seems a particularly nice example, and seems to perform extremely well. Wish me luck!

This will come in handy when they cut the grid

Very nice radio. Personally, I think the BC-348 is an ugly radio, but its place in history makes it beautiful.

Sounds great

Good job

Good sound.Leo.

I used a KWM-2a for a year with a 30L-1 and had a 30S1 w/ 13 ele LP beam as HL9KY in the late 70's.

Wow! I'm having a envy attack. I used to work on R-390As in the 80s. Is the VFO on those a PTO like the R-390?

Good old radio, I am in UKRAINE 🇺🇦

Good evening, could you help me, I have an RF5022 and the original programming cable but I was never able to access it on the computer, I downloaded the software from a website and used Windows 7 and XP but it didn't work, could you help me and my radio has this in the SWR Watts test it shows ---- and when the SWR is high it shows the value watch my videos. PU1XYZ Bruno thanks 73.

What type of receiver was used on Wellington bombers?

Good Bertha❤😂😂😂

In 1986, my signal unit at Fort Huachuca turned in 24 sets of these complete in perfect condition. Reagan turned around the Army and we trained and maintained in the 80s. So these probably went back to a depot. They worked well and after that we got new solid state 125 watts with automatic tuning couplers. Then I read in a HAM magazine, these solid states radios then failed in Desert storm due to static charges and heard they needed the KWM-2As again along with people who knew how to use.

Nice and usefull upload , thanks ! I have an AN/GRC 106 - G4 in the shack, former German Bundeswehr and found servicestamps inside with date of 1996 in it ! It’s a beast ! 73’s from the Netherlands, Tjerk ( Jack ) Polée, PE1IOC ( Rig can be seen at my You Tube upload ‘ GRC 106, another walk around ‘ )

Beautiful ❤

Definitely cool, but I wouldn't trade it for my DRAKE TR4cw/rit. My Drake audio is much better than the Collins. Just something about Drake's audio, but again the Collins is a beautiful rig for sure. FB

nice video

I have a few frequency standards for this radio. The TCO oven runs on 24 VDC. As a Civil Service worker for the Government for 18 years working on these radios. The AN/GRC -106 was fun to work on...

Drooling here.

I know the GRC-106 like the back of my hand still today because I repaired hundreds of them while working 20 some years as a Civil Service Worker for the Government.
