    You are the first guy i seen on radio repair to use a proper mains lead restrainer good job man.So easy to put in old radios you will have to open the hole bigger but never will pull out once installed.

    Found the HQ-100 on top of a garbage can left for dead in 1980. Speaking of headphones, the headphone jack switches the speaker output terminal, and was bent and stuck, thus no audio to the speaker. It was a quick fix. Very temping to try this refurb now, but haven't turned it on in over decade -- and you how many new surprises can be lurking ! Thanks Terry !

    I was looking for the audio mods for the SP600, and I found this episode. Your HQ 100 sounds great and I expect the sp600 has a similar circuit for the mod.

    That is some mighty good sounding AM. I recently got back into AM on 40M with a James Millen 90881 RF amplifier running PP 812A, driving it with a Collins 310-B, modulating it with PP 4-125A and separate PS for RF and modulator. I recently installed my R-390 back in the rack but this little HQ-100 sounds magnificent. I had a HQ-110C and Apache as my first station in 1963 and wish I had kept it. But in 57 years passing, life goes on. I agree with the comment below - great introduction with WWV. Thanks for posting. You might like the pictures I post on my QRZ page. 73 WA4QGA

    Cool! I’ve watched a few of your videos on amplifiers and I bought one of these radios today. Nice to find this video of you doing some repairs. Mine looks about like yours (HQ-100 with no clock). The case has some light surface corrosion but the rest looks pretty good. I’m not a radio guy but have always found it interesting. My dad had a lot of CB gear when I was a young man. I plan to replace the cord and install a fuse before I power it up. If it works I’ll do the other mods you mentioned. I hope this is the beginning of a good learning experience. Thanks for the video, and ya got another sub! 👍
    I also plan to see if you have any videos on antennas as I have nothing right now.

    Instead of just doubling the value of the coupling capacitor, you could improve it further by increasing the value to 10 times the value or 0.1uF. Also retaining the snubber caps wouldn't hurt the performance. Remember: they were added for a reason. Love your videos.

    Hi Terry - really enjoy your videos. I had 2 HQ-100'As, to both of which I added product detectors (6BE6) - details on my website (K3JLS.net). Made a really big difference copying CW & SSB. Once calibrated, the manual displays were very accurate. I used a Hallicrafters SX-99 as a Novice in 1958, and this receiver would have been significantly better, especially with the internal Q Multiplier and the added product detectors. I added the same product detector to an HQ-145 and to an SX-99 a while back - both worked very well afterwards. One HQ-100A came equipped with the same crystal calibrator and the B plus was switched to it by pulling out either the RF Gain or AF gain (can't remember which one). Maybe the new gain control was provided with the crystal calibrator kit - dunno. Had an HQ-110 and an HQ-170 - both drifted a lot, but I used them. Working on these old radios - and I've repaired many of them - brings back a host of extremely pleasant memories. Currently working on a DDS VFO for the Drake TR series - also on the website. Again - really enjoy your work! 73's - Joe - K3JLS PS - always wanted a Johnson Navigator when I was first licensed. Used to read the Allied Radio catalogs after I did my homework and drooled all over the pages - hihi.

    So Terry, I've got a question for you. Like I said, I am really wanting to get into Ham Radio. My question is this: How do you know when people are through talking? I have seen several of these videos you have posted in which you are having conversations with people and I have no idea when you knew to come in and not cut someone off. I am just so used to military comms where you enter the net each time with your call sign and the call sign of who you want to talk to and then let them know that your transmission is over at the end, so that they know that you are done. See these are the things that I don't know. I think all of the technical stuff is pretty straight forward (at least in my mind), but the procedural stuff is what has got me baffled.

    • @ElPasoTubeAmps
      @ElPasoTubeAmps 3 года назад +2

      I know you ask this to Terry but maybe I can help (?). Many people either give your call and then theirs at the end of their transmission, or jus say, "over", or "go ahead" or "QR Zed?" or some slight indicator not so much different than a person-to-person conversation that you will quickly pick-up on that they are about to quit transmitting and it is your turn. You do not have to give call letters each time you start or stop talking - just once every few minutes is plenty sufficient. You meet people that are more "formal" than others but you develop your own style and can sometimes carry on a QSO as if you are in the room with them. On the other hand, there are those that just quit talking and you are not sure sometimes... I get what you are asking and it can be a little confusing but in any case, it's no big deal if you "double". It happens rarely and each QSO is different. Just get on the air and it will all come natural. Once you get your license you have as much right as the other fellow to talk and make blunders and no one will criticize it. Hope this helps. 73

    I hate those couplets. They were using those all the way up into the '70s, even in solid-state audio gear. What's bad about them, most schematics don't give you any indication as to the discrete components that are in it.

  • @hayseed5467
    @hayseed5467 3 года назад

    A question, Terry. There's two different can-caps used in the HQ-100/110 (and A's). The early one is 20-20-20 uF @ 450-450-25V, the later is a 60-40-25 uF, same voltages. They don't appear to correspond to the "A" vs. "non-A". I don't see anything different in the rest of the power supply. Can a guy assume that the latter was an improvement over the former, and should be used during a recap?

    • @bart99gt
      @bart99gt 3 года назад +1

      I recapped one for a customer last night, and used a pair of 22uF caps. There is no audible 120Hz hum and it is easier on the rectifier tube. This one certainly needed recapping, there was electrolyte oozing from around one terminal and apparently had stressed the rectifier tube as it was testing weak on both of my tube testers.
      Note, the 3rd section of the can capacitor is used for the cathode bypass of the 6AQ5, via a really long wire that runs from one side of the chassis to the other. I just elected to use a small axial cap mounted directly to that tube’s socket and dispensed with the long wire.

    I am envious of Terry. He lives in an area that is surrounded by AM'ers with stations running as litlle as 25 watts, we as here in Mississippi there is no Amateur AM activity to amount to anything, yet we have CB'ers running 25KW. There is one here in Yazoo, Mississippi that just upgraded his CB station to 75KW. It's a crying shame that they get away with it being that Jackson (our state capitol), is just 28 miles away, and has a central office for the FCC there. Talk about not doing your job.....
