I was wondering if there are any aftermarket 2.4 modules and receivers which cater for the older style 512 PCM Futaba or JR 'computer radios'...these were the ones without the LCD screen on most cases.
I have a single stick radio from Futaba which is 512 based a wish to make a conversion as there are no longer receivers for these .

Thanks for any input

Maybe.

What is the model number of the existing FM module?

I will search in the closet for it ,but these RF modules were the larger ones not the smaller ones which came out with the Futaba 8 series 1024 radios circa late 1990's. These radios were of the early 90's vintage.

Thanks again

If the module is the larger size that predates the 9Z, etc., then I don't believe you have an OEM option.

If you have a trainer port, you may be able to use some of the module available from either Spektrum or Futaba. If trainer port is not available, you can still tap into PPM signal out to the FM RF PCB and feed that into the 2.4GHz module.

But the real question is, why??? A used DX7 can be had for around $100.

Read his original post. He has a collector's item PCM 8 single stick transmitter, arguably one of the finest executions of that control configuration ever produced. Comparing the hardware to a DX7 is like putting a Mercedes beside a Yugo.

PS: Contact Tony Stillman at Radio South. If anyone can find a workaround for this transmitter, he can.

It is in the case of this single stick transmitter.

Thanks for the replies so far. I believe the Futaba modules are are only 1024 radios; mine does have a trainer port, the round 'DIN' type.If anyone else has any suggestions ,please let me know.

thanks

Didn't I see a single stick gimbal from the old Futaba grafted into a custom 9C Super from radio South a year or so back?

A while back ,I had read that there were modules from XPS which did cater for older radios.However I did a search and I can't find anything about the XPS modules and receivers. Does anyone know of their web address?

There is no reason a Futaba TM8 module will not work with this radio. They work in PWM (FM) mode. It is only a matter of cosmetics. You can take the guts out of the old module and replace with the guts of the new TM8, especially if the old one is larger.

You need to look at the modulation pin on a scope and see if it is correct for the new modules. It might need to be inverted, amplified, limited, biased. Ranges might need realigning.

Tony Stillman will do this for you. Or he will stick an entire FG8 in the old box as previously mentioned.

Tim Schoonard used to fly this radio in F3C.

xps has a 2.4g board you put inside the radio case which connects to the trainer port which turns the old radio into a FHSS 2.4g freq hopper like the new futabas/ATX/hitec.
