    Thank you Dave for showing this tuner. As I mentioned in the last video (Kenwood KA-31), I have this exact same tuner. Imagine my delight when I saw your tuner doing the exact same thing as my tuner. I knew not to use any chemicals on the plates of the Variable Capacitor (Tuner). I did blow it out with compressed air in a can, but it still locked onto 1 station after it played perfectly fine for an unknown time, no matter how much you moved the dial. Sometimes it would magically come back to the frequency it was dialed in to after a random time. I'll definitely try cleaning it again, and tune it with the trimmer as it's definitely off. Love your videos. I learn more every time.

      Look at the frame plates between the pickle slicers. There may be copper or brass plates that are slightly curved so as to put some tension on the main shaft which should be ground. Use a small and I mean SMALL amount of oil on them and see if it comes back to life. Also add a SMALL amount of oil to the outside ends where you might see ball bearings. I've had to do this SEVERAL times on various tuners and it worked every time :)

    Hey Dave ....aka Mr. Grumpy , one lead of the antenna falls off at 8:30. Relax and just glad you are still with us. I have been busy here in Houston after the Derecho and hurricane Beryl tore the snot out of plenty of trees. Nuff said. I will get back to watching your video.

    Dave! I watched your recent review on the Sequre Tweezer surface mount removal kit. I was so impressed, and ordered the same unit. Finally, a tool that can safely remove surface mount parts reducing the need for a hot air station.

    Our shop had few like that. He would spray TUNE-O-WASH in the cap and then blow it out with Canned Air.

    My first thought is that a pigeon came to its resting or storage spot and created relief on the tuning capacitor (haha) but then I figured that would probaby only affect the F.M. band alone. I am not completely 100% sure on this one, though. Let's get into it! :) I would never ever use it for F.M. any longer, but my STR-7045 has low volume F.M, but otherwise is great and A.M. is great. I was told on a reputable and knowledgeable forum that the culprit is highly likely a single specific transistor. I haven't looked into it yet, due to the lack on interest in using radio.

    Much prefer a proper tuning cap than vari-cap diodes. Although push-button pre-select needs a mechanism for units with a tuning cap I still feel like I have more control with a mechanical "air" tuning capacitor.

    • @12voltvids
      @12voltvids  2 дня назад

      No, yesterday it was a power bump when the tree pruners dropped a branch across the primary and tripped an auto reset breaker so it went off for 5 seconds and came back on. The auto reset tries 3 times and then locks out because usually when a branch blows in the branch vaporizes. Where I am it is pretty good except in bird migration time. Lots of birds fly into wires and knock the power out a few times a year

    • @12voltvids
      @12voltvids  2 дня назад +1

      CBC has too dam many positions on the dial. They are on 690 too. And then there are several french stations cluttering up the FM band. The one station I actually want to listen to 98.3 has to share a frequency with another station and where I am I am in the path where both come in, so I have to listen to the station online. I put it on a 100mw transmitter on 88.3 which is the only quiet place so I can listen around the house on a regulator.

      @12voltvids probably the location that you're you're in close to saltwater acts as a conductor for radio waves in the fact that you're on South part of Vancouver you'll be getting part of the US signals you also going to get part of the signals coming out of Mount Seymour that's where your main transmitters are around there CBC probably transmits from that location in Vancouver we're talking about 30 miles difference suspecting you must be around White Rock or closer to that area you're getting signals from probably Victoria you getting signals from Vancouver Island Victoria the US and you getting signal from Canada Vancouver it all comes up once that's all you'll get two stations coming at once they managed to regulate part of the a.m. broadcast as you realize at night you'll have a.m. skip a lot more stations coming in FM is mainly line of sight what's a minor skip when I went down to Pender Island I was getting stations from the states stations from Canada something we're coming on top of each other yes the FM doll got a big clotted a.m. is more interesting money concerns dxing and yes 100 MW can go quite a bit of distance and depending on the type of antenna you're using I definitely enjoyed the videos I like the fact that you manage to clear that tuner excellent Sandy's old tuners sounds better than the newer ones
