Wll believe or not finally got around to the modification....easy as pie, found all three wires I was looking on the encoder board soldered up kit part from HK ....removed the ant. Drilled a couple holes installed new ant. And presto full function 2.4 transmitter with
All The bells and whistles the JR 642 transmitter had, neat!
Only one thing tho I thought I had screwed up something because when I tried it with an old JR 537 servo I had it didn't work, However! When used with a new digital servo WORKS great! Had great range.
What deal less than 30 bucks you get a full function 2.4 set....with a transmitter I was going to trash.

I think there is a 3rd class radio license requirment to open the radio up. Just thought you wanted to know.

Jason, if you had to have a 3rd class Radio License to open it up, then there are a lot of folks in trouble for taking the back cover off to tighten the gimbles.
Hircflyer: what are you wanting to do on the inside anyway?

Well' I have several old non computer type JR FM transmitters which are just hanging on my shop wall. I don't use them any more as I have 2 JR 9303 transmitters. Hobby king sells a 2.4 kit to install on those old type transmitters. I thought for about 15 dollars it be worth a try to upgrade these old transmitters. Figured it be good for a small park fliers. I have several grandsons who could put them to good use
Only has 3 connections to be made...one to the transmitter battery lead, second to ppm output, third to ground....
I can find the power and the ground but having trouble locating the ppm output
I believe it would be the lead to the ant.

NOT the lead to the antenna, that is RF output. You need the wire going from the encoder to the rf deck.
