Hello i have been dying to have my very old MRC 775 transmitter up and running again. I have very little knowledge about electronics but i would love to know where the ppm wire is on the MRC and if you are using lipos what voltage and ma are you using . Many thanks Hugh from Canada
Lovely idea and I have Futaba 6M and Futaba Gold I'd love to make compatible with my Spektrum receivers (currently bound to a DX9 tx). But I'm not an electronics expert (I can just about solder though!) - is there an idiots guide on how to get it right for my old Futaba transmitters? p.s. had posted a comment already but youtube seems to have lost it so hope it works this time :-(
Mr. Mackay, with older radios without a trainer port or even those which have a trainer port but without PPM (old Multiplex radios switched on alternatively teacher and pupil radios, but there was no PPM line!), where do you take the signal information?. Is it mandatory to rely on an Arduino board to create the PPM signal? Thanks!
If you have the circuit diagram, you can normally find where the signal pulse is found. Usually as an input to the RF section of the transmitter. A good example is the Simprop, and luckily a friend in Germany was able to let me have a copy of teh circuit diagram, which does have a pulse signal generated from the encoder section on the Printed Circuit board, see this video where I converted an old Simprop to 2.4 Ghz ruclips.net/video/trztqa30ICc/видео.html

Mike, email me at smackayrc@aol.com and I can let you have more details and photos where to find the PPM signal on your radios

Ordered one for my tbs tango remote it’s JR compatible. Just like the one you showed. Mine said it’s frsky compatible as well?
Dont think the LemonRx are compatible with FrSky unless FrSky have changed their operating system??
Awesome
