Re: FT-101 Main Tuning Dial Off Frequency
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.?

Re: FT-101 Main Tuning Dial Off Frequency
Thanks Geoffrey but that page speaks to the skirt vernier dial.? My problem lies with the main frequency dial just above.

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.

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... 73's Mike KD7VRG

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...

Did Yaesu ever make a matching antenna tuner for the FT-101 series transceiver?
|
Re: FT-101EE shield for 12BY7?
I wonder if the tube shield would just hit the ant loading capacitor shaft. ?

Re: FT-101EE shield for 12BY7?
Thanks everyone for all your input! I will leave it as is.

To shield the bottom portion of the tube. This was not an uncommon practice. 73 -Jim NU0C On Fri, 23 Dec 2022 22:55:57 -0800 "Tony VA7TF, VE7ACF" <20junk20@...> wrote: > All the FT-101 series I have owned and still own, there was never a shield covering the 12BY7.

Hello again group,
On my FT-101EE, I see that the tube socket for the 12BY7 driver tube
is designed for a bayonet type metal shield. Is this factory design? or
did someone in the past modify?? Thinking I better get a shield for it...

Re: FT-101EE shield for 12BY7?
I wouldn't put a shield over the 12BY7 as they run very hot as is. I suspect that the designers found that they got the required amount of shielding required with just the lower part of the tube shielded.

Re: FT-101EE shield for 12BY7?
Hi Mike,
No need to get a shield. ?Both of my FT101s came with a tube base that could take a shield, but neither one came with a shield.?
If you had a shield that would fit in your junk box, I don’t see anything wrong with putting it on, but it isn’t necessary.?

Re: FT101EE Mystery cut wire
Hi Roger, I dont think it is/was for the speech processor. My EE came pre wired for the user to install an SP if desired. All my SP wires are brought up to where the board would be installed.
