Hey great to hear that ! Congrats! Have fun on HF 73

LOL yeah that's true...73

Yeah Tony right but the problem is you never have the right extenders....Thanks for watching 73

Hi Buddy, yes you are right this is a ageing issue..Thanks for stopping by my friend. 73

Well sometimes yes..Thanks for watching 73

Glad that you find a solution! 73

TRX Bench thank you I aligned the radio the voltages were off. like new very happy glad I watched your video from KN4GTU 73's

Thank you!

Thanks for feed-back and for watching 73

LOL Thanks for feed-back 73

Adjusting the VCO coil made a major difference, but it's still not right. More investigation needed.

Thanks for stopping by Larry 73

Hi Janne, thanks for your report! Always helpful for the community 73

Thank you Greg 73

LOL yes that's it :-) Thanks for watching and feed-back . 73

Hi Donald, I always have the wrong extensions on hand LOL... Yeah LP-500 is always in use :-) 73

Thank you Dale 73

Thanks for watching Brian, hope your radio is ok...73

Thank you David 73

Thanks for watching 73

LOL yes I'm the best squeezer in town haha..Thanks for watching 73

Ah got it....It's video 17,18 and 19

Thank you Mike! Yes the LP-500 is great. Minor issues on older radios which are not able to let 200Hz passing for the carrier on spectrum mode. In this case you still need your SA for IM3 tests. 73

Hi Andrei, adjusting the coil is the procedure according the service manual. 73

TRX Bench I understand, i have watched the whole video. However it is odd to me how that circuit could have drifted that much by itself since that inductor is fixed with wax. If the aging of that capacitor was the cause then it will keep drifting as time goes on and it will require periodic adjustments, something that should not happen. I have designed and built a FM broadcast band amplifier using 2 transistors and the gain at band ends is adjusted in a similar manner, by adjusting the spacing of an inductor, due to my general dislike of trimmer capacitors. So i totally understand that. But i know and you know too that electrolytic capacitors are among the first components to fail in any electronic circuit. Just throwing that out there. My vintage Philips PM3050 dual 50MHz oscilloscope had some noise on the trace when i got it, even with the input shorted. Replacing the capacitors in the power supply fixed it. Still a good deal for ~70 Euro. I've had it for 5 years i think, and i see it mentioned in the 1989 Philips catalog - that makes it 2 years older than I am! Still a good piece of test gear for what i do (mainly SMPS work), but it does fall a bit short with RF circuits. I am currently watching your review of the miniVNA because i am interested in getting one. Greetings from Romania. Andrei

Hi Mark, the good news is nothing was broken. It was simply a miss-alignment by aged components. The compound you saw is stabilizing paraffin and it is still good.. Hope that anthers everything 73

@@TRXLab I am sure the wax changes dielectric properties over the years.

Thank you Dino!. There is enough paraffin down on the pcb so I just put my hot solder tip into it and done..Back up is replaced. Buddy is right it is a ageing issue. 73

Danke Peter 73

Thank you 73

Thank you Dan 73

Thanks Grant. If there is enough paraffin left I would not mix it with another material as you never now how it behaves together. Hope that helps 73

Hi Glenn, would be nice if you are able to fix the problem 73

Hi John, well hard to say.. of course a hard hit could potentially do that but I believe those hit must be that strong that the housing would be most probably damaged. In our case the problem is simply caused by ageing... Thanks for watching 73

No I testes the functionality afterwards and everything is working fine. 73

LOL yes you are of course right :^) Thanks for watching! Yes video on the LP-500 is on-line.. 73

Hi Adnan, if I get a radio with no audio in, I will do a video! Thanks for watching 73

will wait for that. Also if u can do a proper video on how to properly test vhf Rx and Tx and their detail parameter checks.i need to see such video as part of preventive maintenance. rest u r doing wonderful job m such a huge follower of urs. may GOD bless u for doing such free knowledge spreading for us.

Are you jealous Steven LOL..As long the entertainment factor is given all is just fine, isn't it?? Thanks for watching 73

Yes its great I love the entertainment love your videos. Thanks

My wife listening 'on the side' wanted to know what video I was watching, lol

LOL, yes absolutely right :^) Thanks for watching 73

If you see dots in the Display than it is a realy comon fail for this radio. The goop in the VCO stages become conductive. The best and unfortunate the hardest way is to solder out the components and remove the goop complete. After cleaning up replace all components and aligin the VCO ports. 73

Other than that it can be a fault in the front end. 73

Hi steve, the coil itself didn't change its value but all the components around did.. Thanks for watching 73

Brady Handel ; I know your comment is old but just want to warn you don't try to plug it in direct to the wall, you will ruin it. You need a 12 volt DC power supply.

Okay Thanks John 73

Hi Neal, for the US I would recommend Buddy from "The Radio Shop" here you find all contact details gokarters.com/smf/index.php?topic=2549.0

Hi Neal, yes that could be possible but a remote diagnosis is always difficult. 73

TRX Bench would I be able to send it to you I feel this video describes the same problem . I am having now no rx or tx on 8.000.00 thru 14.999.00

TRX Bench sorry about getting back to you so late I just forgot about everything

TRX Bench every band works but that frequency range I gave you
