RE: JR / Futaba TX ??? (Not again)
Only in North America is Futaba on negative shift for 72MHz. The rest of the world is on positive shift. Futaba ham freqs are also on positive shift. I fly JR and have a Futaba ham receiver I got from someone else and my transmitter flies it just fine.
As for ease of programming, it's probably pay your money and take your choice. Futabas used to be a bear to program. They have revised the programming several times, but now seem to have it right.
JR has been consistant in their computer radios program since the first. I'm on my 5th JR computer radio and from the Galaxy to now, things haven't changed much and it has been rather easy from day 1. I have used buttons and a touch screen on the 10 channel and have tried the wheel on Futabas and the thumb wheel on the JR 9303. I still like the push buttons on the 8103, but I can see where different people would like different methods.
