It's not gossip because the repair notes from Yaesu tech support indicated that they did a firmware update when they returned the radio to me. And no, the mod doesn't increase the power output on 220mhz.

Oh, oh.... well I think I did it right, and indeed the radio is transmitting above 150 Mhz, but do you get a little flashing "UL" that moves between the 2 transceivers and stays flashing on the side that is not currently selected? What might that mean? I can't find it in the little manual.
Mine doesn't do that. Do you have the U.S version or a different one? Maybe "UL" means "Unlocked"?
"UL" Indicator Appearing After Mod
Definitely the US version, and yes, it looks like it means the PLL is going "unlocked". Sometimes, it appears that both RX's are working, but then I'll tune one side to a different band, and then only the selected rxvr will work while the other side goes "UL". If I select the "UL" side then it goes into lock and receives while the other side goes "UL" and stops receiving. It's not always just when I tune one side or the other "out of band", but it usually happens that way.
I contacted Yaesu, and they will only send info on their "official" mod if I send a copy of my MARS/CAP license. Otherwise they cannot discuss the issue.

Another one down..
Hey @Moleculo and all - thanks for the info! I received my radio yesterday and did this quick mod first thing and it worked like a charm.
I took a before photo to share as some of my components have different part numbers, but essentially everything is the same it seems. No after pic as it's not too exciting of a difference
Hope this is possibly useful for someone! Click the photo to go to it's Flickr page, where you can find a higher res version if you want more detail (1580x1636px)

Yep, software updates work fine. I have not any any issues since performing this modification.
Narrow FM Transmit?
After mod, will the FTM-350R transmit on Narrow FM (N-FM), specifically in the VHF High band 136-174 mHz?

Cross band with Mod
Hello, Sorry for hijacking the thread a little. I have a question if you do the mod can you use the cross band on the 156. freq. To simply the problem I would like to use my truck as repeater for a couple of handheld marine band radios in the field. I was thinking that the cross band repeater function in the radio could be used for this. Any thoughts?
Thanks

This mod has not been tested on a EU model radio as I don't have one.
Yes, the radio will crossband repeat on any frequency that it can TX on.
