Good work, Jeb! I've been messing with an RCI 2970 that loses the AM carrier after it warms up. Still transmits, but the frequency isn't stable and the carrier is gone on the spectrum scope. Interestingly the vco voltages and oscilator are right where they need to be even when it's gone wonky. Any ideas would be appreciated. Checked all the normal 2970 bad solder joints and such.

Thats a nice radio.. how much and can you ship it today

A+++ great job!

I have enjoyed watching the videos on building this amp. Do you have a video showing how you mounted and wired the low pass filter board and the protection boards?

Same problem. Thanks for the fix.

Really appreciate the detail explanations of how to repair radios!

Nice radio with good sound. The more the years pass by the more I appreciate these old school radios. Thank you

Very cool I have a Sinadder 3 here in my collection. Thanks for sharing !

Great Video thank you From Vk3 jjj

I owned a TS-430S probably about 35 years ago (The 'woodpecker' was still in its last days). 100W out the back, teamed with an 'analogue' ATU, 0-30Mhz continuous tune/TX on a 3 element 11meter Yagi-Uda I loved it and now I wish I had never parted with it. I recently got back into Amateur radio (Foundation Licence last January) and in the summer bought a FT-991A The 991A is better in _almost_ every way technically speaking but I _really_ miss my first proper radio, it just had way more character, taught me so much and revealed so much on the bands whilst spending hours just rolling the dial and listening to absolute gems. To see your video, you breathing life back into an old friend with such care brought back good memories. Thanks for sharing this.

Thank you very match you save my day good video and useful trick thanks a lot

Same exact issue with the one I have. The trimmer in mine is 200K. Glad I found your channel.

Can you tell which case model you are using? Informative video, thanks. Looking forward to the finished pics and power test.

Making good progress. Thanks for the video.

Question sir. What causes it for those solder joints to crack? Next is, if an hf radio that was working as it should before and was put in storage in a hot and sometimes humid environment for more than 15 years, and now, it just turns ON. One with half a display horizontally, the other has no display at all. No RX, just the typical hiss sound on FM on both radios. Not sure of the TX because I don't have the proper antenna for it yet. Both are IC-735's that is from my late father inlaw's. The other one had normal RX for just a while and lost it, the other one is just quiet. Whst do you think is the problem sir? Would recapping it and changing the internal battery bring it back alive? Thank you sir.

Well done Sir! Top job.

It would be a shame to bust it up for bits. Personally, I would persevere and take pride in my efforts when it's back to it's former glory. They are excellent radios. Chris, G0VOE in Somerset, England

I haven a Hickok 380 and it works like a charm.... Great diagnosis ..... You should be knocking on 100,000 subscribers ..... You have a great channel..

Awesome diagnosis ...... That IC chip is actually big enough to solder in with a small tip.... I use a JL02 bent style T-12 tip..... I clean the pads with wick then add a lil solder to the most easiest corner pad to get to ..... I then place the chip and tack that corner in so to speak .... Then I solder each one after that .... Yes I do have a hot air station like you have , but I only use it when I have to.... Nice lil radio right there ........ Keep them videos coming .....

I'm glad you persevered on that unit , too many good radios are parted out for hardly no reason...... That guy must have been slinging his soldering iron everywhere in there , that was a mess ......

That's a nice lil rig right there ...

It reminds me of my R5000 with the same dots. In that case it was the PLL with issues.

Thanks for sharing your knowledge

Great work. Glad it was something simple.

Off to a good start!

Love watching you work Jeb! Picking up a few tricks from you. Thanks for the videos!

Regulator

Turn you Amplitude down on the generator and you scope will look better or drop voltage u need to check your am regulator

hi my counter was bought used and the 10mhz adj trimmer is chewed up, any idea what the min/max pf is for the factory trimmer ? also is a manual or schematic available for this counter ? barry

i'm not much of a commenter but nice job i like the way you show all the work

Hi Jeff. I had a similar experience with a TS-130S a year ago. It had several strange issues, and I did spend a lot of time with it. For me it was a valuable learning experience. In the end it was a nice radio. It came with the external speaker & vfo, so it was worth some money. Thank you for sharing this! If you fix the display, let us know. 73

Good job

Resurrection time

Part it out,get rid of that headache

Nice

Lepiej kalibrować na porównanie dwóch sygnałów X-Y ( Lissajusa ) ładniej widać :)

Ciekawy układ

Ciekawy układ z rezonatorem kwarcowym nie widziałem takiego rozwiązania. Pozdrawiam

Witam. Miernik fajny miałem taki, ale poległem na naprawie. Sprzedałem. Mój miał TCXO . ... Pozdrawiam

Whole point Buying 1 is it should be Bang on 10Mhz,,!! So i have to buy another to set this 1 ? useless .. i got 1 How far off are they on average ?

I had to add a resistor

I had that same problem on that very exact oscillator

Some new info was posted by @ellisgl on the first video. @ellisgl - That seems to be a common issues of you read the reviews. Just need to replace the trimmer with a larger value iirc. Thank you @ellisgl

Thanks for the video. I ran into the same problem of insufficient adjustment range. I followed your method but 150K didn't get there, I had to use 47K on mine. Thanks again!

Very useful video. Thank you!

what is the program u are running to track the satelites

The device is a sine wave generator, out does it do other stuff too?
