Has anyone actually done this part of the FT-301 alignment? On 4.0 MHz you adjust T2 & T3 for maximum output power. Then adjust T1 for best Rx sensitivity. Problem is that all three of these in the "Tune" or preselector section are seriously "gooped" in place. I could remove the hardened resinous material, follow the procedure, then use something to lock them in place again. But is it worth it??

This radio is putting out about 82-85 watts on 4.0 MHz, and sensitivity is pretty good. Maybe not worth it, just to do a "complete" alignment...?

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...

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 Joel, I’ve the same problem but I’ve located the damaged parts in the schematic!

73 Marcel DK1NL?

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.

Mike KD6UJS?

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.

Hi Marcel,

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

Just given one. No supply or cable.
Needs cleanup and testing IF someone is interested in it.
I'll do this if I know its going somewhere if its OK.

I live near Charlotte, NC
It goes to recycle otherwise.

Hi,

Hello Michael, you’ve a lot of spares.
Do you have a “tune” knob?

Greetings Marcel.

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

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)
