Re: FT-101 Main Tuning Dial Off Frequency

 

Bruce,

I can't find anything listed anywhere but it looks like TC1 adjustment trimmer cap in the VFO should do it. I would note the position of the cap before moving it so if you need to return it back you can. I would tune the main dial to a known freq of a net for instance, and try the adjustment to bring the receiver to it. It shouldn't take much adjustment to do this if it has just aged and shifted over time. You can access TC1 by lifting the processor board that is on top of the VFO box. TC2 is the drift cancellation adjustment. TC1 should be the one you want.?

One thing you might check is to make sure the lubberline, or the indica line is square with the center of the dial.?

Sometimes the escutcheon of the front of the radio gets put back on a little askew.?

I know it's a longshot, but might be worth looking at. Just a thought...

Hi everyone.

I'm still looking for guidance on how to adjust the main analog dial on my 101-E to match the received USB frequency.? I recall seeing something about making an adjustment on the VFO unit but I'd appreciate confirmation and what exactly to adjust.? If there is a special method to use to make this adjustment I'd appreciate that info also.
Thanks!
Bruce

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,

Richard kn7sfz

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
