In continuation of the FT-101 series I have an E model on te bench with no output.
We will see what caused the failure and repair this back to proper transmit.

I can't describe how much I enjoy every 101 video you do! Thank you for such a professional and good quality work. Way better than Netflix!!!!!

My goodness this was just perfect. The wait on Yaesu 101s was worth it. Neutralization and all. No one does what you do and shows what you show. Your teachings allow me to love this hobby even more. Priceless. Thank you Sir. One day an alignment video and the world is perfect hehe

Thanks for the kind words. Will be getting into alignment in the future.

[@BruceNitroxpro]

@@TheRadioShop, I'd like to know if another ham radio operator, Paul Carlson, is right about the MANY alignment videos he has put out here. He does things for a reason. If you have a different take on the same stuff, please, point it out. If you use the same basic method, but on DIFFERENT kinds of receivers, PLEASE help us all understand why and how you do it! LOL de KQ2E

[@TheRadioShop]

@@BruceNitroxpro Hi Bruce. Interesting question. Let me say this. Paul is a master at what he does. The guy is a genius. His thought process and teachings are far superior than any I have ever seen. Even though I think we both have unique thought processes on how we do things and achieve the goals needed to repair a unit, I am far from his league of expertise. Why I do not even try to or imitate his style.I have much respect for him and three other creators as they are responsible for my success. Since I am self taught in electronics I use a laid back simple approach to what ever I am working on. So to really answer your question I think we both do the repair in the same manner just the delivery is different. Paul is highly educated, I am just an old farm boy. Thanks

[@marciuschester7739]

All of you're video's on the FT-101 E have been very educational. You're knowledge/experience stands out like a search light amongst candle's. Looking forward to seeing more and hoping that you will do an alignment video in the near future especially when it comes to the receive.

I'm in the process of watching every single FT-101 video you have. Priceless knowledge and I agree on the labour factor as well by learning how to do it yourself. For years i used nothing more than the inbuilt calibrator in my TS-520S or FT-101E, the power meter and a dummy load. Maybe a second receiver if I needed it and a cheap volt meter. In the process of getting better gear now. Thanks for all of these 101 videos :)

[@lylewatts6370]

Great FT-101E radio repair. These radios just keep working and working if a little TLC is used. The plug in boards make repairs easy and lots of parts around from unrepairable units. Tubes are still available but costly. These are my favourite transceiver and I have 3 of them. Thanks Buddy for working on this old classic radio and I am sure there are many hams out there that still use them.

Keep them coming Buddy. 73 DE K7RMJ Frank

[@624radicalham]

cuban9splat He's right. Every forum confirm this. This was the most popular radio for 11 meters

[@TheRadioShop]

You are remembering correctly my friend. That is just what it does. The switch in this radio is fairly easy to disassemble. But you can only do a few times before the little fingers break off. Part of radio maintenance is keep them clean so you do not have to go into that far. Yes folks do not understand that restoring a radio can out weigh the value quickly. Most of the time I do not do "rants" but felt like it needed to be said. Thanks as always Frank. 73

[@TheRadioShop]

@@624radicalham Agreed. Second most rig ever used on 11 meters was the 101. The fist was the Swan 1011. Not to be confused with the Siltronix 1011C. That was just a cb.

If there's a single transciver that belongs om the list of greatest HF's ever the 101 series, might be number 1. If not definitely in the top 3. Besides the long warmup period before it stops drifting (which most transcivers of this period suffer) I can't think of anything else that the rig suffers from. When all is dialed in correctly they're not only superb sounding SSB performers but it's AM audio is awsom! I'm assuming an online search can substantiate how many were produced and sold (millions?) There are so many still on the airwaves and sell in almost any condition. There's an eBay seller who specifically refurbishes and sells them. Parts are easily found as there's many parts 101's for sale. Then there's those who specifically buy them in order to part them out. These 101's might be on the air for another 100 years. No matter how small and highly advanced HF's become there will always be those who don't mind having to spend 5 minutes tunning them up in order to get them on air. Truly a peice of HF history that's still highly sought after. And those buying them aren't doing so in order to put them in a cabinet so that they (the 101) can be admired behind a peice of glass. If you're not one who needs DSP ect ect technology the 101 is imo a spectacular amateur radio. Yeasu hit the nail on the head when they got it right. I've read there were bugs in the earliest ones off the line. But those bugs were quickly worked out. And as they say: the rest is history. Great clip. Great repair. On possibly the greatest HF ever to come out of Japan (or anywhere for that matter.) Keep up the excellent work. And sharing. Thank you, 73's PS. The 101's receive is also on point. I will always stop in order to listen to a qso when one or even better both stations are using one of the 101 transcivers.

Great video! This has helped me understand more about the FT-101. I recently was gifted a FT-101E from a fellow ham and I plan to restore it. It was last used in 97 and was working then. I will watch your 101 playlist to see what I can pickup. But I thought I would ask you, do you know of a reliable source to get a power cord for an FT-101E? I see some on Ebay but have had people warn me on the QRZ forums not to buy them from Ebay. Also, do you suggest I look for anything specific before I try to power it on? Someone told me to use a variac and raise the voltage in stages over and hour or so to condition the electrolytics since it hasn't been powered on in over 20 years. This is my first rig with tubes in it, so I know to be careful, and it creeps me out, but they're such beautiful radios an should be on the air. Any tips or advice is welcome. :-)

[@bblod4896]

When you neutralize a tube, do you mean the capacitor shorts out the transmit tube so it doesn't oscillate when you're in receive mode?

[@vhfgamer]

Capacitors block DC voltages and pass AC voltages. So if you wanted an amplifier circuit to not have stray AC voltages bouncing around then you typically have a capacitor to ground. I don't know tubes, but if this was a transistor amplifier then the capacitor I speak of would be attached from emitter to ground. Also you would have such filter capacitors between two stages of amplification so the DC voltages don't back feed and blow up your transistor. Correct me if I'm wrong Buddy! I'm young and still learning.

[@russellhltn1396]

All tubes have some stray capacitance between elements. That can couple the input to the output in a way that can cause the tube to oscillate. Neutralization is about canceling the effects of that stray capacitance.

[@JamesGMunn]

I have seen mention of some kind of bias setting or neutralization or something on high power amplifiers with the Tx tubes out, but it seems like maybe they substituted something for the tubes temporarily. I would guess maybe a high voltage power resistor and capacitor(s) to simulate the Tx tubes to allow adjustments without risking the big tubes but this is just a guess. Do you have any hints on what this process might be? Sorry for such an unclear question but the people who do it seem to keep it as some kind of secret.

the cold neutralization is the same thing. the interelectrode capacitances of the tube are still there its just not emitting because there is no heater voltage.
