Thanks for the trip down memory lane. I built one in 1967 while I was stationed in Turkey. I used it mainly to listen to the BBC and the VOA to get news and happenings. We had no TV and only had old newspapers. Also did some listening on the ham bands. We were not allowed to transmit.
Jeff, I picked up a GC-1A two years ago at the Memphis hamfest for $45. It is in mint condition with both power supplies and has been re-capped, plus it came with a nice clean copy of the manual and tuneup instructions. It also included a color copy of the restoration for the GC-1A. I don’t know if it was for the one I have or a different one, but it is very detailed. The owner told me that it might be a little dusty inside, so when I came home and opened it up I was expecting layers of dust, cobwebs, dead bugs, spiderwebs, etc., but it was spotless! I don’t know why he thought it was dusty because it was absolutely mint inside. As I mentioned before, it was re-capped with no evidence of previously ruptured caps or overheating. It was a single-owner radio built by the Ham that sold it to me when he was a young man. When I get the time, I will take a picture of it and upload here. I want to thank you for all you have done by taking time to make these videos of Heathkit products. I’ve probably built most of the ones you have demonstrated and some, more than once. 73 - de Mick - WB4LSS
I've restored several Mohicans and have never found a defective transistor. It was one of the first radios to use crystal (ceramic) filters in the IF section: no IF alignment and fine selectivity. The whip antenna is massive and the radio receives better than most modern portables I own on AM with built-in antennas. SSB is unusable because of temperature sensitive oscillator drift. A nice radio for any collector. Long live AM!
Brings back memories. Back in the late 70's a friend of mine gave me one of these that he had found in a garage sale or something. When he found it didn't work and not being into electronics he passed it on to me. After many hours of troubleshooting, I found a suspicious looking solder joint (pretty much the only wonky looking solder joint in the whole radio) and when I re-flowed the joint with a little fresh 60/40, the thing came to life and worked perfectly! I bet the guy who built it would have screamed if he found out that one bad solder joint in the literally hundreds of good ones he did stopped this from working! A nice old "boat-anchor" to be sure!! 8^)
Wow, what a detail. Me and my two buddies, all aged 14 to 15 back then, using two stroke mopeds, stole 2400 cb stations, walkie talkies and hams. Turned out to be, state customs magazine we found, in never finnished tunnel. It was before Gorbatchev came to my city. 1989, i think. Yugoslavia.
Beautiful radio, it is in great condition and you did a great job of explaining how it works. In addition to being a back up receiver it would also have been the type of receiver that a new ham would have used in their first station.
Your presentation of this radio brings back memories. Back in the day, I was impressed by this radio; maybe more about the appearance with its shiny, silver knobs than its performance. Then a friend brought one over for repair. Now I was impressed with the innards. His radio had an open coil; one of the bigger ones. Of course, Heathkit stocked them and sent it right away. Thanks for the memories.
Thanks for the review, Jeff. I picked up a mint version at a thrift shop for $70. It has the AC option but no battery pack. It's about 500 kcs off in alignment but I'll take care of that as soon as i can get my hands on a signal generator. Surprisingly sensitive, and the "transfilter" makes for very sharp selectivity. I've only used it on the (original) 54" rod antenna and I'm able to pick up all the usual standard shortwave stations plus hams from 10 meters down to 160. BFO works very well for CW and SSB. It is single conversion, so it does have some image problems, but far less than most SC receivers. I got mine for nostalgia's sake, since this is the first radio I ever built, way back in 1963. It's not as selective or sensitive as my Tecsun 600, which I consider the best portable available for less than $400, but it's close, especially for a radio now over 50 years old. Well worth the money as a standby receiver and general casual listener.
A nice looking set, equally well in the home as well as the radio shack. I've never had any Heathkit but the circuitry and manual must have been reliable for so many people to be able to construct them.
A very good demonstration Jefff there was was one on the UK Ebay Ham Radio Receiver site a few weeks ago in very good condition I was tempted but have too many Short Wave receivers at the moment thanks for the Demo.
Some giveaways to discovering a factory wiring job is if the leads all are stripped the same amount and are generally stripped longer than you would - and mechanically sound wraps on every strip and lastly, excess wire - no banjo strings.
What you can get for it depends on condition but mostly on whether you can find a buyer interested in it. A recent check of ebay showed a number of them that sold for between $30 and $200in the last few months.
All my radios with Germanium Transistors still work just fine. The oldest dates from about 1957-58. These include Regency ATC-1 ham band converter, heath GC-1A Mohican, SBE-34 transcievers. The Mohican is well worth having for general listening. Remember it is a Positive Ground radio... do not blow it up !

Beware ! This is a Positive Ground Radio !~! ! Pay Attention if you use an external power supply... and be super careful if you hook it to your ham station 12 v supply and use coax which is connected to a common station ground ( through an antenna switch or swr bridge).. as all modern 12v radios are Negative ground... best to use it with an entirely separate power supply or batteries. Heath did great engineering on the dial mechanism, and the bandswitch and coils for the rf, osc, sections is very much better than cheap Japanese multiband radios that came later. The germanium xstrs are actually pretty high gain. My dirty example has very poor AGC.. but I have not replaced any paper / electrolytic caps in it yet. Leave ceramic and mica caps alone ! Sure would like an original manual and antenna for mine. 73 W6WUH
I used Heathkit radios in Jr. High School for starters. Cannot remember the model(s) any more but our school would get loaner transceivers now and a again a Yaesu and Icom I remember. Been out of the loop for too long and trying get some airtime again. Nice rig. I've some older rigs stored away I need to get set up again - KD7CEO.
This is another gem that I used for many years... It's performance was fair, but it did tend to drift some. Nonetheless it gave me many years of pleasure and was sold to a guy who still might be using it!
I had one of these in the late Sixties, and built it from a kit. I thought its electronic performance was impressive. I ended up using it mostly for AM radio listening, and at least got the benefit of outstanding sensitivity and selectivity-not so far from what you could do anyway, relative to the theoretical limits of that type of broadcast. I got to listen to Cousin Brucie in Michigan. I guess that's worth something. . In other respects, it was pretty clunky. I even thought so at the time. No rechargeable battery, the handle was not retractable (and the antenna not fully), and the way you switched between power packs was especially crude. It did not use its interior cabinet space effectively-lots of wasted room. The dial would have worked much more smoothly as a vernier, circular knob. But what really irritated me, more than anything else was that, if you ran from AC power, noise, from things such as fluorescent lighting fixtures, came through the power line-whereas it didn't with batteries. . Shortwave radios have come a long way. I see there's an ICOM that does direct digital sampling and displays the spectrum in real time. I think it's smaller than the Mohican! Alas, there isn't much to listen to on those bands any more, especially if you only speak English. Truly, we have some very old wine available in very new bottles.
Jeff, I think this is a very good overview of the Mohican. One attribute with is actually exceptional is the very low current drain and long battery life. I think the current draw is on the order of 35 or 50 milliamps ( from memory) by comparison.. the portable FT-817 draws nearly 1 amp ( 200 times more) in the receive mode. The huge difference is due to the use of digital frequency sysnthisis, memories, and even filters. Of course they radically different capabilities.. but put some alkaline D cells ( not available when the Mohican was made) and the run time probably runs into months ! This is exceptional in anybody's book. True, there are many old analog Japanese Shortwave portable to be had that can do this.. but they lack the CW/SSB capabilities, antenna matching, and muting provision that makes this workable in an emergency or cabin ham set up. Careful cleaning and use of de-oxit D5 on the controls and yes the transistor's plug in sockets, and careful alignment and calibration.. will yield a decent reliable radio.. well engineered and built with high quality components.. that will out last us all. Penson is to be taken with a grain of salt ( maybe pepper cause he makes me sneeze ! ) .. since the SB series featured GC shortwave versions.. that rivaled Collins.. a far cry from the GC.
Jeff, Thanks for showing your radio and sharing all the information you have on your GC-1A. I just got one and surprisingly, it came with the AC power supply and battery holder. My radio works, but I've got a hairline crack in one of the electrolytic capacitors, which I'll replace. Should I replace all the electrolytic capacitors? Regards, Tom
+Jeff Tranter Y would only do that if they are defective, agree most off the oldies are out off spec's, but that doesnt matter that mutch, iff the selectivity drops, its a good idea to investigate,or re calibratem butt to change caps just because there old is a hoax., iff there defective, it will show!
A single IF stage made this receiver prone to images but there were fewer sources. At the time the Mohican was a decent performer. Put it in a typical home of today and the IF shortcoming would be readily apperant.
You did an splendid job! That receiver is really suitable for Ham Radio. Too bad those are out of reach and no longer made. Thanks for sharing. 73 de Rob. YS1RS
That Heath S-meter seemed extremely liberal. I would like to hear how She sounds on SSB, it was designed when we were experimenting with product detectors and hang AGC etc. The Collins 75A-4 was the standard for SSB audio back then unll the Drake 1-A came out which became the new standard. 73, K4OF.
It would've been a decent receiver for a novice, though they probably would've needed help with the alignment. I think another reason the battery packs are rare is that people left batteries in them too long and the batteries leaked and destroyed the parts inside the pack.
A very nice looking receiver but with it being Positive ground same as the Eddystone EC10 it was a awkward git to match to any other system. It was a shame that both of them were designed using PNP germanium transistors. That is what were available at the time. I was going to have a go at converting my old EC10 to modern transistors and never got round to it, thank God. 73 de John - G0WXU.
Dear Mr Jeff Traynor, These are excellent videos you have done. Sir do you know if there are any New Old Stock "Heathkit Shortwave Kits" for sale, by any person or company? Perhaps there is a successor manufacturing company similar to Heathkit, or Radio Shack. If you would advise me, I would be thankful. My interest in old tech increases daily! Kindest Regards Jeff
This receiver was extra quirky in that it has positive ground which made operating it in North American automobiles gtricky. It overloaded very easily with an external antenna and no matter what care was taken in the alignment process the dial was horribly inaccurate. Regardless, it was a fun project and I used it for deveral years. I no longer have mine but I know where it is. 73, VE3EUR
I put an internal speaker and extendable antenna in my DX-160, I'd like to see a head to head between this reciever and a DX-160. The DX-160 seems to be a total rip of it years later, so it'd be interesting to see if the DX-160 outperforms its grandfather or falls short. And that view of the underside point to point wiring.. 30 hours assembly time... bahaha... more like 150 hours, and then you get stuck with a useless box because you don't have a freqency generator to align the blasted thing.
nice rig all u need now is a dipole longwire antena i had a tube one and there cool to use and owne this new stuff today sucks n made in china these heathkits also made u learn electronics by putting in a lil problem for you to find
I just bought a 1962 model , with the optional battery pack !!!!
Perfect condition+Works Great !!!!!
All for $60 bucks!!!!
Thanks for the trip down memory lane. I built one in 1967 while I was stationed in Turkey. I used it mainly to listen to the BBC and the VOA to get news and happenings. We had no TV and only had old newspapers. Also did some listening on the ham bands. We were not allowed to transmit.
Sorry you had to be stationed in Turkey.
Jeff and Bob, thanks for this memory jog. I built one around the same timeframe as Bob, and had it for ~35 years. William, KD6RG.
Jeff, I picked up a GC-1A two years ago at the Memphis hamfest for $45. It is in mint condition with both power supplies and has been re-capped, plus it came with a nice clean copy of the manual and tuneup instructions. It also included a color copy of the restoration for the GC-1A. I don’t know if it was for the one I have or a different one, but it is very detailed.
The owner told me that it might be a little dusty inside, so when I came home and opened it up I was expecting layers of dust, cobwebs, dead bugs, spiderwebs, etc., but it was spotless! I don’t know why he thought it was dusty because it was absolutely mint inside. As I mentioned before, it was re-capped with no evidence of previously ruptured caps or overheating.
It was a single-owner radio built by the Ham that sold it to me when he was a young man. When I get the time, I will take a picture of it and upload here.

Wow, what a detail. Me and my two buddies, all aged 14 to 15 back then, using two stroke mopeds, stole 2400 cb stations, walkie talkies and hams. Turned out to be, state customs magazine we found, in never finnished tunnel.
It was before Gorbatchev came to my city. 1989, i think. Yugoslavia.

Jeff, I think this is a very good overview of the Mohican. One attribute with is actually exceptional is the very low current drain and long battery life. I think the current draw is on the order of 35 or 50 milliamps ( from memory) by comparison.. the portable FT-817 draws nearly 1 amp ( 200 times more) in the receive mode.

Do these actually work? Or do they make good boat anchors.
Jeff,
Thanks for showing your radio and sharing all the information you have on your GC-1A. I just got one and surprisingly, it came with the AC power supply and battery holder. My radio works, but I've got a hairline crack in one of the electrolytic capacitors, which I'll replace. Should I replace all the electrolytic capacitors?
Regards, Tom
I would recommend replacing the electrolytic caps if you plan to use the radio on a regular basis.
+Jeff Tranter Y would only do that if they are defective, agree most off the oldies are out off spec's, but that doesnt matter that mutch, iff the selectivity drops, its a good idea to investigate,or re calibratem butt to change caps just because there old is a hoax., iff there defective, it will show!
A single IF stage made this receiver prone to images but there were fewer sources. At the time the Mohican was a decent performer. Put it in a typical home of today and the IF shortcoming would be readily apperant.
The mohican has 3 IF stages
Wow great Video I just got one from my dad,it's in great shape!!!

OMG, the Realistic DX-160 was a complete rip of this unit which predated it by how many years?
I just found one of these with the battery pack.
A real plus is the Extremely Low Power Consumption for battery operation.
You did an splendid job!
That receiver is really suitable for Ham Radio.
Too bad those are out of reach and no longer made.
Thanks for sharing.

A showpiece!
That Heath S-meter seemed extremely liberal. I would like to hear how She sounds on SSB, it was designed when we were experimenting with product detectors and hang AGC etc. The Collins 75A-4 was the standard for SSB audio back then unll the Drake 1-A came out which became the new standard.

It would've been a decent receiver for a novice, though they probably would've needed help with the alignment. I think another reason the battery packs are rare is that people left batteries in them too long and the batteries leaked and destroyed the parts inside the pack.
A very nice looking receiver but with it being Positive ground same as the Eddystone EC10 it was a awkward git to match to any other system. It was a shame that both of them were designed using PNP germanium transistors. That is what were available at the time. I was going to have a go at converting my old EC10 to modern transistors and never got round to it, thank God. 73 de John - G0WXU.
cool rig id like to get my self an old unit my self
Do you know if this one was a factory-made? Its interior looks a little too neat to be kit-made.
It is possible, but there were many builders back in the day that did a very good job of construction, so I think most likely it was a kit.
Dear Mr Jeff Traynor, These are excellent videos you have done.
Sir do you know if there are any New Old Stock "Heathkit Shortwave Kits" for sale, by any person or company? Perhaps there is a successor manufacturing company similar to Heathkit, or Radio Shack. If you would advise me, I would be thankful. My interest in old tech increases daily! Kindest Regards
Jeff
Es una hermosa joya 😊

Jeff, What do You know about those Majestic Radios from Germany?
I own some radios made by Rogers Majestic and Grundig Majestic. Was there a particular model you were asking about?
how to buy this one?
My unit is not for sale. You can find these radios on eBay, but they can be quite expensive.
@@jefftranterics thank you Sir. I am really really fascinated by this one. If you have any supply source, kindly help to inform me.
Very nice! But I hear a bear to align
Thanks, you did a great job.
This receiver was extra quirky in that it has positive ground which made operating it in North American automobiles gtricky. It overloaded very easily with an external antenna and no matter what care was taken in the alignment process the dial was horribly inaccurate. Regardless, it was a fun project and I used it for deveral years. I no longer have mine but I know where it is. 73, VE3EUR
I put an internal speaker and extendable antenna in my DX-160, I'd like to see a head to head between this reciever and a DX-160. The DX-160 seems to be a total rip of it years later, so it'd be interesting to see if the DX-160 outperforms its grandfather or falls short. And that view of the underside point to point wiring.. 30 hours assembly time... bahaha... more like 150 hours, and then you get stuck with a useless box because you don't have a freqency generator to align the blasted thing.
I like it want one
What a beauty... you had to be a human beeing in order to use it. Unlike "smart phone" psychopaths of today. Presidents included
nice rig all u need now is a dipole longwire antena i had a tube one and there cool to use and owne this new stuff today sucks n made in china these heathkits also made u learn electronics by putting in a lil problem for you to find
Nostalgic,,,,!
Interesting--thanks!
There would eb MORE of these Radios around if WOMEN didnt throw men's stuff away!
It wasn't only women!!! I had some very precious irreplaceable radios I was working on that my dad threw away!!!
