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 http://k0lee.com/ft100/ftfreeband.htm)

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: http://www.fj45.com/ham/FT-100-Batt.asp

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.

I see what you mean. You have not only the harmonics, but a sub-harmonic too.  I wouldn't know where to begin with answering why this is happening within FLdigi. Hopefully someone else may provide a clue as to why this is. For me with a direct sampling connection from the external speaker socket on the radio, I only every see the fundamental.

This time with attachment hopefully ..

Here's one of my favorite EddyStone Communications receiver,  Model EC10.

These are a very nicely engineered bit of kit. This particular EC10 has the battery pack adapter, which are usually very hard to find these day.

However this can be swapped out for the mains adapter pack, which sits in the same slot in the back.

Everyone should have at-least one EddyStone receiver in their shack or collection.

MF and Full HF coverage over 5 bands. AM,CW and SSB modes.
