I recently picked up a some used receivers to use with my MX sport and MX3 FG radios.

I tried to bind them on both radios and the rx led will not stay lit after blinking fast. I tried to find info on the Airtronics site but they did not list the 92724 model. It appears that it may be only compatible with FHHS-3 transmitters? Both radios I have are only FHHS-2


Anyone know for sure what model radio these will work with?

Thanks for the help,

Mark
