Thanks for the journey , it was very enlightening !

Hey that could be a Capasitator, a Resistator, a Trasformator. Just replace the Yhinga mijeger. <-- Just being funny. That's what people who would bring things to my shop giving me Ideas. What SIMPS.. Just found your channel. you got a New Subscriber.

Hi, Fluffy Lamby'...!

Mine worked perfectly for years in my shack and just recently I got a report that I was throwing an FM carrier, but my audio was gone. Has worked perfectly otherwise... No clicking. Just no sound on transmit. Go figure. Hoping to find that it's some obscure setting I accidentally hit.

Congratulations, well done! W8SOO

Well done!! 73's

Where did you find that swivel to hold the board?

Ive picked up a 101E recently. Typical cracked mica caps but other wise seems to be in good shape for its age. Looks bone stock internally and surprisingly, the VFO is tight but not overly....nice and smooth with no slack. Looking forward to reviving it.

I have two of these radios. Dyno Motors run about $100 or more . To me I'm smart I know that I don't have enough experience to tamper with it for now. These radios look like jewelry to me I'm not selling them

Does the c13 cap have to be a certain direction?

Very interesting video..I have a Yaesu 101-F have bias.ill check tubes is ok..but only do 2 watts in 40 meters..in 10 m no do any watts .I'm interesting in put the radio functional.. appreciate your help

👨‍🦯

Keep trying.

No documentation available for any of these

73s Cordial. Thanks for sharing. I really enjoyed it. CT1COB Portugal.

Great as always!

Great job. Will it do the GMRS FREQs ??? I need it to transmit on 467.735.

Tenho um Yaesu FT 101 EX ,👏🏻👏🏻👏🏻👏🏻

Maybe I missed it, but did you talk about the "protection mode" at all on this unit? I have one that has gone into protection mode and I have found little to no information on why or how to fix this problem. Thanks.

Well done. Thanks.

Excellent as always!

Very good presentation. I'm working on my EE also.

Super interesting and educational as always!

Kudos to you for some really good detective work IMO. I replaced both 10k resistors on the PB-1314A regulator board (one on each side of the bias adjustment pot) after trying to track down a run away oscillation problem which red-plated the finals whenever flipping the heater switch on. Turned out to be the bad 82pf mica coupling cap between the driver & finals, which I replaced with a new one from eBay, 82pf@1KV. It failed too in a couple days, over heated the reg. board resistors again & cooked a nice set of Toshiba 6SJ6C’s because I wasn’t paying attention & red-plated them. So changed the 82pf again with a brand name one this time from either Mouser or GigiParts @2kV, & new 10k resistors but went up to 1/2 watt resistors this time, & an old set of finals to check for the correct voltages on all the PA tubes’ pins on the sockets underneath and voltages on the reg board at the bottom where the board plugs into the long socket- no more red-plating the finals with heater switch on. Also used a recap kit on the regulator board. Using american 6JS6C’s, & was able to cold neutralize them without replacing the 100pf mica neutralizing cap on this particular rig, an FT-101EX. It works now, lol. GL- enjoying your videos! 73, W8SOO Ken

Just watching , mine had no IC , have got it going now so be interested to see what your issue is ..

Hi1 i'm Brian M6 bAQ. i'm trying to fix my ft101b. RX is fine on all bands, but only transmits on 7mhz and 3.5. As a matter of fact I've had some great copies on 7mhz. What could be problem, please? CAN ANYONE PLEASE SUGGEST SOMETHING, I'VE BEEN TOLD DIODES CAN BE PROBLEM, BUT IF SO, WHICH DIODES?

Reference: QST Issue: Jun 2001 Title: Simple RF-Power Measurement Author: Wes Hayward, W7ZOI If you are an ARRL member you can access this on line Has specific instructions re constructing a -40 db tap. As constructed it’s pretty flat out to about 650 MHz. And about constructing a power meter. It says: “measurements from nano watts to 100 watts”

thanks. do you have a link for the manual?

Hi! Awesome video, thank you for posting. Do you have any suggestions for the same model power functions fine, but the meter on the front is stuck somewhere between 8-10v and 10-12 amps. Needless to say on meter moves slightly when adjusting voltage, or drawing amperage. Meter returns to to all the way left resting position when off. I metered voltage, and it’s outputting just fine. Thank you in advance!

Hej, w moim 757GX ostatnio zaczęła rozłączać się sekcja filtrów LPF w pasmie 24-28mhz, na krótki czas pomogła wymiana diód D01-D06 na 1n4148 jednak po pół roku problem powrócił. Po godzinie działania trx pasmo 24-28mhz wyłącza filtry i brak wtedy nadawania i czułość jest bardzo niska. Prawdopodobnie jakaś dioda albo coś innego jeszcze "przecieka". Gdzie szukać problemu?

I have a ft101b, which isn't transmitting on 14, 21, 27 and 28, can I just pull that fet out?😊

My condolences to you and your family.

You can probably find a repairable HP8640B for a reasonable price. Very good sig gen. You present your information well, one of the better videos. I, too, am working on a FT-101 EE

Good thing you didn't use a 4 - digit meter😁

I've started to look at your videos about the FT-101, I bought me a B-type a few days ago, that an amateur bought in 1974, he used and updated this rig for 25 years, in 1999 he bought a new rig, and placed the 101B into a glass display cabinet, and another 25 years later he sold it to me! He doxcumented Everything he did to improve this radio, so he gave me a Big origanizee folder filled with documents, original manual and original schematic of this radio! Plus 2 original unused final tubes and one smaller tube, so I'm going to be recapping too, for the very first time 😊, thanks for filming all this! Kind regards Geurt Broens PD4GB Nijmegen, Netherlands

I will do this mod, hope i dont brick the Yaesu though... tnx for this, 73, Levi in Sweden

Does the radio serial number on the rear panel agree with the number on the right side chassis?

The top of those new capacitors look like bare metal. Seems like a shock hazard on the upper cap in series. Using the same clamp is outstanding. I'm working on mine time permitting.

What is your reasoning for not washing the boards with soapy water and then drying in an oven? I’ve seen others clean this way so I’m curious what the risks are. I really enjoy your videos and explanations in troubleshooting. 73 Tom

Mine is a DM-330MVT - uses C3306 transistors instead of mosfets but don't they work the same here? Mine had low voltage (2V) and no fuse blowing or protection faults. Replaced the transistors with the mosfets you used and now it lights up the protection light. How should the NPN's check out? I will put them back and start troubleshooting again. I read that these are common problems so I jumped the gun but need some help!

Just to add the germanium diodes in the DBM can fail

Hi buddy i have the same fault ,i looked at the modulator boars buffer all ok ,have you looked at the HF if modual ? and the frequency output into the driver tube ? at 29MHZ i have 25.8 MHZ looks like the mod oscilator is not mixing to give 29MHZ.

So interesting as always! 👍🙏

Now think about it . I don’t think the myth busters had the right tool for their experiment . And all of a sudden , you come up with the right tool . Your SWR meter . With that you check antenna matches . But did you know , you can use it for a field strength meter too ? See , when you put a magnetic mount antenna on your car , you can ( with a little help ) walk around your car , and find out what is best direction your signal is going to radiate best from . That’s why I say , your signal is radiating best if your antenna is at center of mass . ( say the center of your roof . ) try it . Walk under power lines , or around a radio station antenna . You will be very interested in the results .

I was just looking a myth buster episode , about testing various myths in radiation . This one episode delpt with UV and cooking on a tanning bed . Um , and another dealing with radio waves . Then an intriguing question came up . The busters came across a Johnny Carson show with Lucial ball as a guest . And as the interview was going on , she told a story about , driving around Los Angeles , and hearing in her jaw radio signals . She said it was coming from her teeth ! She revield in her interview that she had been going past a radio station at the time ! Um , and later she passed a vacant lot , and hear chattering , like moris code ! Well , the FBI must have been told about it and the newspaper said that a Japanese transmitter was found in that location . But Lucy was left out of the story the newspaper told . ( very HUSH HUSH ) . 🤫

👌👌👍👍

I had just bought my EE, and the first time I plugged it in and touched the coax from my sig gen I got shocked. Whereas it is a two conductor cord with non polarized plug I just inverted the plug into the AC socket and that fixed it for the time being. I ordered a grouding cable online. I did check for continuity from either side of the line plug to chassis and found it open, so maybe some capacitor leakage? I got the electrolytic replacement kit yesterday so today I have a lot of soldering to do.

I had a hot chassis on mine. Bought a 3 conductor power cord.

Good job with the FT 757GX !!! Looking forward to hearing soon more from this fantastic radio. 73's

I just got one of these it is very good condition with documents including original bill of sale and documents on all the mods and new parts installed in 1996 and new tubes in 2000. I just got it home yesterday and have not turned it on yet still researching it is my first amplifier. It has a small red toggle switch on the front I think this might be a standby switch and a big toggle switch added to the back top left not sure what that is for yet. Might have a few questions for you at some point not in a hurry to put it on the air yet need a tuner. Looks like it has had all the mods and new parts installed based on the sales receipts I have that came with it.
