Mr Carlson, the big manufacturers should take a look at your videos. With all their millions they don't come close to the professional quality you achieve in your humble home lab. Thanks again. We are all lucky to benefit from your ability and efforts. Can't wait for the next one !

Mr. Carlson, another successful and wonderfully demonstrated troubleshooting system. Keep up the very professional demonstrations.

Another fantastic video, Paul! Nicely done as always, and good catch on the cable mix-up. Watching your videos, I feel like I am being schooled by a master. Thank you for the education!

Thank you for explaining what you are doing. it's like having a guide tour to a country you have never been too!

I did see the coax mix-up right when you said something looks wrong here. Most of my component level repair has been digital and it's been many years. Your videos have inspired me to get into fixing radio gear. Thanks for that.

I've been a Motorola Two-Way Communications dealer/service center since '77. With that said, that FT-1000MP is something which I would not want to contemplate having to perform repairs on. Gimme an old MoTrac, or something ancient from Comco any day!!! With all of that said, that Yaesu is definitely a nicely constructed piece of equipment, and you've once again accomplished a quality job of troubleshooting and repair.

Paul, as usual, a great video from you. Thanks for posting.

Thank you Paul, always enjoy your troubleshooting videos.

I see that I am not the only one excited about another new video. Again thanks for your time and efforts taken to provide us all with such quality information.

You sir are quite gifted, very refreshing.

I am just beginning to set up my work bench. The equipment you have in your lab must've taken a while to acquire. Your videos are fantastic. You clearly explain the steps involved in removal and what to be careful of. You are a gifted individual in both creating the videos as well as electronics diagnostics and repair.

That was fun. Thank you Mr. Carlson.

Great video. Really love the repairs of the newer actual rigs. Outstanding Kevin

I respect the way you do repairings mr. Carlson, it's just a perfect job again, congratulations!

Great bit of fault finding Paul. A pleasure to watch as always

me again, I could watch you videos all day long.... great instructor...

I love the channel. I learn something new each and every time I tune in. Glad to see you back.

the most well explained elettronic video i found here on youtube.it s a pure pleasure watch your video from start to finish.

Great video... i really appreciate your gift of logical pursuit.... having been in the radio repair business many years ago... watching many "shotgun repairs"... thanks very much !!!

Again, clear and knowledgeable video. You have a great teaching style. Thanks again for the effort you put into these.

I appreciate your channel. Although radios like this are not in my area of interest, it's very helpful to learn electronic troubleshooting processes. Thanks for doing what you do!

Once again an excellent informative video! Well done!!!

I am also so respectful of your work ... you make things look so easy ... I hope I can gain knowledge just to look after my own equipment ... my TS940 IS IN GREAT SHAPE ... BUT SLIGHTLY OFF FREQUENCY ON RX &TX ... I will be looking for a video where I will be abl to achieve a standard as good as yours ... Thanks for the videos it gives me a great insight into electronics ... Many Thanks again ... Mike ... M0csi ... Manchester. UK

I really enjoy your videos! As a FT-1000MP owner myself, I've found these videos even more interesting.

Nice repair. Just a walk in the park for you. Thanks for the video.

I always used to say the first two things to look for was anything that moves and anything someone has messed with. This video sort of proves that out. Great video , would love to have a lab of his quality.

Great video as always. I would like to see how you put you RF probe together.

I truly enjoy you videos. Great learning tool showing hands on troubleshooting.

Another great video Paul! You are a superb teacher and I have learned a lot from your efforts. Thank you ! Greetings from Arizona.

Well done Mr. Carlson, thank you for the lesson.

Mr Carlson you make it look soooooo,easy,thank you very much for sharing.

Great video Mr Carlson thank you for sharing your knowledge.

Really enjoy the troubleshooting videos Paul thanks for another one, job well done !!! Lloyd

Thank you Mr. Carlson.

If Mr Carlson were a Marvel Comic character , electronic repair would be his super power ! Another superlative video !

All I can say is excellent video Mr Carlson! Thanks, Arnold.

I used to repair audio amps. This video made me miss being a bench tech and troubleshooting. 73

Great repair and work! I'd be interested in seeing the probe build and a video dedicated to AF/RF/MOD signal probing work.

I do not do short wave but your presentation is great! You are a first rate tech! Guitar amps are for me, and I know you video what ever comes to you. Understandable. Keep up the good work! Thankz

Super logical and precise. Definitely the kind of tech I'd want fixing anything of mine.

Great video, as usual! I could watch your stuff all day! Keep up the good work! It would be a dream of mine for you to look at my own transceiver and see the repair process. I tried to get it fixed by numerous techs around Regina and nobody could track the problem. Can't wait for your next video! 73

Terrific video once again......I learn a bit more each time I watch these.

Thank you for another great video! I'm going to watch the RF active probe video right now!

Great lesson and video...Thank You! A back-to-basics video on probe construction (and the application/use of the various type's of probes) would be very much appreciated.

Love your videos Mr. C. Thanks as always.

Always nice to have the right tools and cables/connectors for the job...those pesky "TMP" coax connectors/jacks are hard to attach to if you want to measure something coming from or inject into a PCB. I added some homebrewed cables with BNCs on one end and the TMP on the other (RG-174 or similar small coax required). You can get the TMPs online and they're very reasonable and easy to solder/crimp onto coax. TNX for another great repair video Paul! 73 - Dino KL0S

Another awesome video, thx Paul.

Makes it look so simple. well done as usual

Another well documented repair. I did one of these some time back that had the same problem. The regulators seem to be a week point in this model. Like you I liberally apply heat transfer compound to the heat sink. I believe that may be what's making them go out so frequently, to much heat. Mike

Amazing LAB this guy has. cool video and great fix

Another great job, Paul.

Another interesting video. It seems one of the hardest parts of working on modern electronics is how to get them apart without making the problem worse. You made that repair look easy.

Another great FT-1000MP video. I guess those 9 volt regulators are a common failure in this model and something every tech working on them should definitely be aware of.

Another winner Paul...love to watch the troubleshooting. LOL I see old one thumb is still with you...LOL

Great video Mr. C and a yes please on the Eico probe.

Great video! I really needed a Mr. Carlson's Lab fix! :-)

Another great video, highly enjoyable and informative. Thank you and well done sir.

The front of that thing looks so impressive 😎

Glad to see a new video. We missed you. I would also like to see the video on the probe.

whoa you blew my mind with picking up the transposed filter coax - I know some shops that would have spent hours on chasing that down.....experience is the great test instrument .

Excellent Video Mr Carlson, Thanks for posting :-)

I like your mix of vintage and (relatively) modern test gear.

Very interested in the RF probe build Paul... I hope you do that video... This one was great by the way... as usual...

Thank you for sharing, Paul !

Thanks Paul. Nice job.

Thanks. I enjoyed this a lot. More please.

I enjoyed it very much, Paul. Thanks for sharing. Big thumps up. Take care

Very Nice video Paul very well explained and great detail. Thanks for that

Hello From Mark/N4VER. I have a Yaesu FT-920 that I had a”Freak Accident” with. My FT-920 has the outboard Behringer Eurorack UB-802 that has a pigtail cable between the EQ and the 8 pin microphone connector on the 920. I was going to disconnect the microphone pigtail and unplugged from the EQ and the tip of the plug made contact with the cabinet of another radio in which I heard a distinct “Pop”. The 920 still has normal receiver audio and the transmitter still keys manually via the “MOX Button” on the radio as well as the antenna tuner still seems to function normally. I have tried the EQ which still seems to function okay. I do realize that Yaesu has not supported this radio for quite some time now and I do realize that this radio is old - But there’s nothing out there brand new that I like as well as this FT-920 unless I maybe found a nice FT-1000MP which is still a pretty old radio. My question is, Is the audio circuit in this radio destroyed enough to trash this great old radio? I have actually watched your work with the FT-1000MP some time ago and remembered you in what you accomplished. Thanks & Best Regards DE Mark/N4VER Versailles,KY.

A new video!! Cool, can't wait to watch.

I'm pretty sure that you do but I hope you get as much joy from making these videos and working on electronics as I do from watching these videos and working on electronics. It's simply wonderful to watch you work. 73 NE5U Mike

Another classic repair Paul Really enjoyed that. Always fun watching you troubleshoot as you explain what is going on. And another here for going with the active probe. I have an Eico probe just like that hanging in the rack. Would be a nice project for it. Thanks for sharing and a big thumbs up. 73 Buddy

Great job Carlson!

Nice fix Mr Carlson.

Well Done Mr. Carlson!

You make it look so easy!!

Can u do a history review of the path u took to get to where u are today... Your incredible

Quality Japanese electronics have a beauty to them as unique as their cars. A working piece of art. Too bad someone stuck all those filters on that one. Thanks for another great video.

Another nice video. Keep up the good work.

Somebody has fitted a Inrad Roofing filter Mod and got the wires crossed and not read the fitting instructions. I have just fitted one to my FT1000MP. great improvement to the imd.

Another great video... Thanks

Great vid as always!

Good work Mr C

Spot on MR C.

I don't even know nothing about this stuff but I'm gonna buy this box.... I love tech/ gear

Great.! Nice Nice detective work Mr. Carlson.

Kenwood TS-520 was my first, hope you get one soon. Another fixed and out the door.

Good troubleshooting Mr. Carlson. Those 78/79 series three terminal regulators require adequate heat sinking, especially when running at 75% of their rated output. These also have short circuit protection. from the Fairchild spec sheet, short circuit protection is around 250 ma. "Each type employs internal current limiting, thermal shut down and safe operating area (SOA) protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. " Interesting that even with it's built in thermal (SOA) and short circuit protection, these devices can still fail due to inadequate heat dissipation and thermal compound not being used. 14V to 9V drop across the device at 700 miliamps would indicate that at least 3.5 watts has to be dissipated by the series pass element inside the device. That would require adequate heatsinking. Your test device monster heatsink looks about right, unless there is adequate air flow around the device from the fan.

structured work, nice one.

A nice easy fix for you that Paul but only because your a genius love your videos Paul thanks for sharing.

I know little to nothing about electronic repair. I have be watching various videos and even your video which is way over my head it is still interesting. I want to be able to repair my own computer flat screens, tv's and other run of the mill garden variety gadgets.

Love these videos.

Nice job.. I always have trouble finding 7809's... last time I was in my component store the only had 7885 regulators.... 8.5vdc... these things are great... they will work until they start smoking...

Thanks for the beautiful and easy explanation how to proceed step by step in the troubleshooting of the transceiver. One should have at least two of the instrument you used like an oscillator -generator ant the necessary h.f. Probes. You have used too. Thanks very much for the lesson.abele.suisse

Sonofagun, Paul, you got lucky again. :-) Excellent vid, my friend. Very well explained. Thanks, lad. Regards, John

your a very smart guy !!

Thanks Paul...

Nice methodical job, well done.

Tnx for rep.video Paul, very enjoyable to watch. It seems that the: "Thy shall always check voltages" is of good use and fine electronicks-mantra. :) ..Didnt see the wrong put internall coaxes at first though.--so perhaps an aditional nice mantra to "Thy shall always check for other misshap-tamperings" too .. --> and you are good at check for these things in your videoes. Thanks again, apreciate very much. br,Rolf

Very good job!...Wish I had someone to repair my TS-2000.
