The ongoing 72Mhz AM reciever saga

Postby FlyBoy » Wed Sep 22, 2010 11:43 pm

A question for the electro whizzes out there. Can a 27/29 MHz receiver, or any other receiver for that matter, be converted to 72 MHz, and if so , is it a big task and, is there anyone that has the know-how to do it?

Not as yet, at this point I am wondering if it can be done, and if it is worth doing. There are plenty 27/29 MHz but not many 72, hence my enquiry.

It can be converted but generally speaking, it's not worth the effort.

You'll have to rewind the front-end and oscillator coils.

I recently received a Futaba 6Xsuper in an E-bay auction that was 35Mhz. I am in the US and the majority of the FM users are at 72Mhz. I purchased a Corona DIY module kit and converted this radio to 2.4Ghz. I really like the layout of the 6XAsuper radios, and had never seen one labeled '6Xs'. I am currently using this radio for all my planes, as it is in very good shape. Due to the excellent reviews by Bruce on the FrSky system, I plan to purchase some of these DIY units to upgrade my existing Corona and other 72Mhz radios.
These DIY modules are very easy to install, and I will never worry about converting anything from one band to another, other than 2.4.

Hi Bryan.
I have done the same hack with a Corona kit in a Multiplex Cockpit MM, and it works 100% A OK, I use the MM for my Sloping in Hamilton NZ.
I also have a Futaba 8FG, but the receivers are too expensive for sloping, so they go into my thermal planes, however I am looking to get my 10 year old grandson involved.
I have a very nice 2x4 with 72AM single stick TX but no RX. The next step would be to 2.4MHZ the small rig for him, but I am again not sure if you can convert an AM TX………….can you Bruce.
