Hi Tom,

?

When the meter switch is set to ALC and you PTT, the meter should go to full scale at 5. ? The meter will deflect down scale from 5 depending on how loud you speak into the mic. ?The downward meter spikes indicate decrease in gain depending the peaking of your audio.

If you don’t see the dipping of the ALC when you are speaking then you may have to look at the ALC circuit underneath the PA tubes.

Hello all ... any advice gratefully accepted. ?Transmits approx 20kHz above receive frequency. ?Clarifier seems to work correctly . ?Do I start on the power board? ?Thanks

In the process of removing the VFO unit to clean and re-lubricate the reduction vernier, apparently the gasket between the VFO unit and the front panel broke in two places. ?I don’t see any reference in the manuals to identify a part number so to see if Yaesu might have stock. ?This gasket provides a seal along the VFO unit edge, and I would like to replace it, if possible. ?Please let me know if you have any information or suggestions to replace the gasket.

?

Thank you,

There is a seller on ebay that apparently has 11 of them for about $13 each.? I could not find the schematic in my files, and even FoxTango came up empty...

?

Good luck!

Is this what you mean? My FT101b has no raised lettering either. I thought this was normal.

Okay, here's a couple of pics of a FT-101FX dial bezel. I tried to capture the non-embossed nature of the lettering.

Hi All,

?

The issue I had with the original RL1 relay in my FT-101 is that the meter circuit was not working due to the relay.? I had cleaned it a few times bit did not correct the problem but it made it worse.? I decided to replace the relay with a Magnecraft W67RCSX-12 relay as per written in an article on the Fox Tango website by Wayne N4YI.? (Thank you Wayne!)

?

I just completed the RL1 modification in which I replaced the original AE-3271 relay with a Magnecraft W67RCSX-12 relay.

?

The image below is my write up of what I did using Wayne N4YI article.

?

?

?

The original article was for a FT-101E, so I compared the schematics for my FT-101 (late, pre B model) to the FT-101E and found that Yaesu did not change the harness wiring for RL1.? After making the wiring change my FT-101 meter now works.? The receiver checked out and I did a transmit test by loading the the transmitter up on 20 meters into a dummy load and checking the audio modulation on one of my other radios.? It appears the mod with the new relay works.?

?

I am posting this info for anyone interested, but as a disclaimer you do it at your own risk!

Hi Roberto,

?

I found Jackson ball drive replacements here for my Heathkit HW-101 here. ?They should have one that can be used in your radio. ? ?

Thank you, Jim, much appreciated and helpful. If you can follow-up with the photo, that would be great! I'd like to see that they match.

Not an "authoritive" answer, but

?

I have seen 2 FT-101F's in person (I owned one, but it was a parts radio - having been completely abused and destroyed internally by CB usage - fried the HV transformer and output section), and both of them had the same type of sticker (not embossed like the "E" models) for the Model, on the bezel above the VFO knob.

?

I sold off the chassis years ago, after having removed all of the boards, output pi network, knobs, etc. I may have kept that front bezel. I know I kept the front panel, because it is in absolutely perfect condition - paint-wise. I will have to check. If I did, I can take a pic. and post here, if there's interest.

?

Yes, I also thought this type of sticker was slightly odd. It reminded me of very early 101/101B (Non E). It was very similar to those from what I recall.

?

So yes, I think this is the way they came from the factory.

I never heard a response to this... thought I'd check back a few years later to resurrect the question. :)

?

Whoops, I realised that I didn't actually confirm; my radio is now working as it should.? Thank-you Giuliano.

Thanks for your response Giuliano.

?

What I did was open the case and give the jack and mode switch a good spray with contact cleaner and work it back and forth.? It appears I may have had the same issue as you.

?

Also, for the record, when in CW mode the side-tone should emit on key-down regardless of the MOX/PTT/VOX switch setting. ?

?

Kind regards,

? Lance, VK7TO

?

Lance,

?

I got exactly same issue.

It turned out a oxideized contact on a mode switch section , cured with contact cleaner.

Of note, you need also to turn on the heather switch? which has a dedicated switch,? to let VOX to work properly.
