Re: Schematic jpeg?

 

Hi Richard, I suppose that you don't have a good pdf reader as the FT-101E_Late_Schematic.pdf in the files section is high res 11 x 30 inches. I just added a jpeg version of the same file in the same folder. You could put the pdf version on a usb stick and take it to one of the printers (Kinkos?) and get a full 11 x 30 inch printed.

FT101E No Output Power

 

All,

Hi Joe here. Thanks in advance and your help in my quest to get an FT101E back to health.

A friend of mine, an elderly ham, was transmitting without an antenna connected to the radio. Yes, that’s right, without an antenna. This cause the RX and TX to fail. This happened several years ago and over this time I’ve been able to get the receiver working as it should but the TX is still not working. Using the radios internal calibrator I get anywhere from S9 to 10 over S9 depending on the band.?

I did put a good set of tubes in the radio but there is no output on 10,15,20, and 40 meters, and about 5 watts on 80 meters. I haven’t checked 160 at this point. I’ve replaced C13, C125, C131. The driver and final tube voltages are fine. Relays are fine, and I did swap relays from my working 101EE to no avail, as well as trying couple sets of known good tubes just in case.

A couple of things to note.


The -100 volts at PC1076B reads -170 volts, but this is what my working 101EE reads so not sure if this bad.

There is no voltage on Pin 5 of the mixer board, which should by 13v.?

On 80M I hear crackling on receive, like a bad tube or a bad cap, and the plate knob acts like the the preselect that “peaks the receiver” but not as significant as the Preselector knob,

I do have proper idle current of 60ma.

On 80M, the Preselector, plate, and load controls do peak the output power, ?but again only 5 watts.

Another test I did is I pulled out the final tubes and transmitted with only the driver tube and clearly heard both a CW and SSB voice signal on another receiver.

I am using a 50 ohm dummy load for the test.?


Any help is greatly appreciated.

Joe

Mike, it is on upper side band.

Re: FT-101 Main Tuning Dial Off Frequency

 

Sorry Bruce, I just reread your initial post and see that it is the main analog dial that you are talking about.?

Is the radio on AM or SSB? Just thinking that might make a difference. Maybe not 12kc's but...

Mike, the main dial shows I'm at 14.048 when I inject a 14.060 Hz signal from my Elecraft XG2 receiver test oscillator.

Bruce

Re: FT-101 Main Tuning Dial Off Frequency

 

Bruce, is this a FT 101zd? IIRC, I had to net the reference crystal in the counter module in my zd. I think it is accessible through a little hole in the top of the counter case after you lift the processor module. It has been a few years since I did this so the details are foggy.?

Thanks Geoffrey but that page speaks to the skirt vernier dial.? My problem lies with the main frequency dial just above.

Please advise how to align the main frequency dial with the actual frequency being used.? I'm referring to the top lighted dial.? I recall seeing somewhere that there is an adjustment (pot?) which requires removal of the speech processing board but I can't locate this website again.? :-(? ?

Re: Help needed for FT-101EE

Update:

Naturally...right after I posted this thread, I went back in and did some snooping.

Took out relay RL-1 for examination under a microscope and found many of the contacts welded shut and/or very carbonized and dirty.? Upon a very thorough cleaning and burnishing, everything seems back to normal - or at least back to the way it was before.

Subject: [Yaesu-FT-101] Help needed for FT-101EE

Hello group,

My 101EE has taken ill and I need your help with troubleshooting.

I'll try to lay out the events chronologically in order to explain what's going on.

* Unit was used primarily on 80m achieving 100 watts out for about a year. No real issues
* Unit then sat unused for about six months.
* Unit brought back up but with considerably less power out (~20 watts max on 80m and far
??? less on higher bands.
* Checked the 12BY7 driver tube on a tester and it showed marginal.
* Replaced with another 12BY7 (tube had no markings, but was in a box labeled "12BY7' and
?? it had same form factor as 12BY7.
* About 5 seconds after turning heaters on, smoke appeared. Specific location of smoke source was not obvious.
* Turned unit off immediately after seeing smoke. (Maybe about two seconds worth of smoke)
*? Replacement tube was apparently NOT a 12BY7!!
* Upon extensive visual inspection, I cannot see ANY fried, melted, cracked, blackened,
?? or otherwise damaged components or wiring. Everything all *looks* normal.
*? Unit still receives perfectly fine, but...
*? Will not key the relays when PTT or MOX is activated. Stays in RCV mode.

I'm wondering if I can get some help with trying to figure out what got damaged
and what I should do to troubleshoot and get this thing back working.

Any help appreciated...
