Technical Corner / FT100 11m ('wideband') mod
« on: September 18, 2021, 09:19:28 pm »
The details for modding the Yaesu FT100 to include 11m are readily available on the net, with the mod details having being posted on several sites (eg

The instructions are perfectly clear so I won't repost those here. But exactly the same details (verbatim) and picture are used in the reposts. One slight problem is that the picture used isn't very clear, and one other thing to note is that the jumper must be unsoldered. Those are lead-free joints, so a hot iron is needed. My 40w iron made easy work of it (ish) but it does need some encouragement. A bit of switch cleaner and a cotton wool bud then cleaned up the debris afterwards.

I suspect most FT100's internal lithium cells (CR2025/2032) will, like mine, have completely run down by now. However, I can confirm that the mod holds even with a run-down memory battery (so the mod must flash the ROM). I will replace the battery some other time: I use memory a lot on other bands and to tune the '15' on the end of the UK FM channels (ie on VFO), I have to switch to USB, alter the step, and hop back. But here are instructions for the battery change in case those are useful:

Here is a video of me testing it on Friday (before the band pass filter was fitted). I made a mistake here in not altering the contrast to get a (more typical & not limited by a close ceiling) blue waterfall. But it worked v well. I was running between rooms and didn't hear John's call.

In case it of any use to any one else who doesn't use Windows too much, I have a Windows VM on a USB drive that runs on Mac and Linux (the same VM). Virtual Box is a good choice - it is free (as in beer) and open source.

Yeah never seen it on the WF before then.
will have a think.

PS gained 2m on the antenna hight from using a 5m push up. Worked a chap in Bucharest who heard me on first call & gave a good report & saying good signal for the setup. Slowly in right direction. Going to think a bit more on mast. Got through to Jabber but they sold out. ...

Here is that photo of those harmonics I mentioned, Will. Quite interesting -stopped me going off to bed there - looks to me as if the 750 is a 1st harmonic of the 1500 (fundamental f) and then at ~2250 central a first harmonic (wider because of the multiple) & then to the left of 3000 (central) one leg of the 2nd harmonic.

A bit lazy of me, but I decided to go for this off-the-peg lead, which should be good:
