Thanks Roger, just grabbed it!
I have a 46 inch flat panel monitor, which makes it very easy for
me to zoom in and out and navigate the large jpeg image, which I
do indeed prefer to the pdf version (I have Adobe reader).
I don't believe I'll need to print it out, as that is a little
more difficult with these old eyes.? It reminds me of a folded
schematic I have that goes with one of my old Galaxy V
transceivers.? It's about 2 1/2' tall and 4' wide, so I had to
hang it in front of me and it sure took up a lot of real estate!
??
The saga of my hard of hearing EX model continues.? I checked out
the bulb fuse and it was fine.? I then removed the HF board,
cleaned the edge connector and and RF mosfet? (3N211) socket and
still weak receive.? Then, following a well made YouTube video,
checked the? mosfet with a DMM and it seemed to respond well, so I
guess I won't need to replace it.? I suppose now it's time to jump
in with both feet and follow the signal path after I read up a
little more on how it's processed.
For anyone reading this who'd like to chime in, here's where I am
so far.? with a small length of wire in the antenna socket, I can
barely hear my signal generator on 7.100 with no S meter
movement.? When I connect the sig gen directly to the wire, it
gets much louder and the S meter moves up about halfway.? The VFO
seems to work fine and is accurate, as I can tune back and forth.?
However, turning the preselector has zero effect in the volume or
meter movement, so something is amiss there.? I'll probably post
this on the Facebook group as well.? I know I'm not the first one
to go down this road...haha!
Thanks Roger and everyone,

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.

Sure Peter..her you go:
With that group and the great folks on this reflector, I feel very
confident that I will have my 101EX hearing well in no time!

The chopped up schematics in the downloadable PDF manuals are

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

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

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.?
