Your results may vary, hi. Let me know if this found it’s way to you. Big problem with these is they go microphonic because of the VFO. I took a few of these apart in the beginning and kept finding

I built a manual years ago. Organized with a tab for each board with mods and allignment procedures. Unfortunately it is mostly hand written. I did send some doc’s to g4fph can you ask him to

I can send pics of VFO strapping if needed. Appears not to be in VFO manual from Elcon.

gm Dave, it seems you have quite an experience with the FT-301! Can you upload your 9MHz IF Alignment hints to this group? There might be several owners who are interested in a correct alignment (e.g.

Elcon sells a VFO stabilizer for the 301 VFO. I have bought many of them. They work great. Easy to install. Dave

For many years' now, I've had one of the early 'miniVNA' units from Mini Radio Solutions sat on the shelf. It doesn't get much use these days, as it's functionality is bettered in most respects by a

Just to round out this thread. Given a good crystal filter on the NB Unit, there would seem to be no real need to modify the transceiver to bypass this when RF PROC = OFF. By chance, I came across a

Dave, Thanks! The serial number for the one I have on the bench is in the 7G 110xxx range. I believe that decodes to May of 1977. This morning, I installed the NB Unit from one of my other '301. Wow

Oh. And PS. I modified a few of the IF boards per Roland. He’s a smart guy, has a doctorate in electronics! Way smarter than me but the IF mod didn’t work right. Had a side effect so I put all of

The filter on the NB board is only on the hi power models. Forget the computer stuff. You need a tone generator and a signal generator. I use a IFR 1200S and a Motorola two tone generator to adjust

The 301 had a couple of bugs out of the gate. One is the “crab walk” problem on the pre-mix board and the other major one is the one your working on. I wrote an a alignment procedure for the one

Dave, Thanks for the mails. Yes, please send a copy of your alignment procedure. You clearly have a lot of experience with these old things. Agreed, no service manual, as such (not like for the

Digging into this a little more today. Using my SDR transceiver as a narrow-band, RF spectrum analyser, I checked the DSB TX IF signal going into the Filter Unit. Audio fidelity from the mic. I

Hi to all in the group! I'm close to the end of repairing an FT-301D transceiver and trying to get the transmitted audio quality sounding anything like 'nice'. It's proving surprisingly
