Hi,

I just came accross this thread.

I purchased the complete Ft301 line back in 1979 still have it brand new and in boxes. In the early 90’s I purchased a bunch of the IC that get programmed for the FP301D.
I looked into this as well and have schematics to make the programmer for the 74188.

Feel free to contact me I would love to get this going again.

There are other FT-301 groups on (groups.io)

Hello Bo.

The 'AD is the only one I need for the series. Put me on the list, if the other(s) don't work out.

(currently have: 301, D, SD, S(x2))

Thanks,
Jim

Hello Michael, you’re right, they both don’t fit at the 301.
I would choose a Shure 444 or a black Turner.

Hi Marcel,

Nice collection!

I’ll see if I can find a the proper knob, not sure if I have it.

Question for you what desk mic are you or would you be using for the 301? MD-1B8 or YD-844 these don’t really fit the look of the 301. Ive seen the YD-844 with the 901 and the MD-1B8 with the 767.

Hello Mike, I collect old Yaesu radios and I already had the little brother the FT-221R.

The “tune” knob is not original and want to replace it.

Greetings Marcel DK1NL.

Re: Tune knob FT-301

Hi Marcel,

What is your story regarding your new FT301, why did you purchase this radio? What parts are you needing?

When I first saw this radio back in 1979 I fell in love with it and purchased the entire station, it’s still in boxes.

Hello, I’m a new user in this group.
Yesterday I bought a FT-301 and the tune knob is replaced.
I want to make this rig original and perhaps is here somebody that has a spare knob and want to sell it?

Greetings Marcel DK1NL.

Hello Marcel,

It’s good to hear that you have solved your problem. I’m not sure what is causing that failure, but perhaps there will be a few more ! 73 from Calgary…

Well, I’m glad I didn’t try too hard to find a replacement pot. As I was taking the old one out I realized one of the traces underneath was cracked. Patched that and I’m back in action. Who knows why it worked as long as it did, then just died suddenly…?? I’m OK either way, just happy to have it going again.

Lesson: Look for the simple, mechanical things first!

Update on my FT-301

#166

Got the radio re-assembled the other day. Installed LED's in place of the three incandescent bulbs. Trying diffused yellow, as I've always felt the white bulbs gave the front panel a too-stark appearance. Might change my mind later.?

Made a few contacts on 20 and 75. All said the rig sounded great. Then suddenly kaput, no output on sideband! CW is fine. Strangely, the mic gain potentiometer inside the rig has gone open. Tried re-soldering the connections, and ran it end-to-end about 20 times. No change. So weird !!? So now I'm in need of a replacement. Or I suppose I could try disassembling the pot to fix it, but that seems doubtful. I've got all sorts of pots in my parts drawers, but not a one that's 470-1k ohm or so and would fit in that location.?

Minor item which will be solved soon enough, but a bit disappointing. Oh well, on to the internet I go to search for a replacement...
