Just wanted to share a quick fix I've found, sorry if it has been posted already on here, I couldn't see it when I searched for it. Long story short, I'm not too fussed with the bluetooth headsets with the FT3D, having read some of the issues people had had with them, I opted to go wired. I had a voucher for a UK ham radio shop, so bought a little Heil HTH-Y. After I ordered it I read some reviews stating that it won't quite fit in the jack socket on the radio and function correctly, some have had to grind a small sliver off of the headset's jack plug. Sure enough, it arrived and didn't fit properly, no PTT and had to hold the PTT to get any receive audio. Luckily I couldn't find my Dremel, so bought one of these little adaptors (pic attached) for use with phones with chunky cases, which get the same problem apparently. Think it was about 4 quid on Amazon.... Brand is Fospower, but I'm sure there are tons of others available. Works like a dream, just checked it out on the YSF parrot. Looks a bit goofy coming out of the side of the radio, but thought it could be a good fix for anyone else with this issue who doesn't want to grind their jack plugs... Cheers, 73 Rich.
