Hi, Manolo!
No hablo spanol!
I try to answer in English!
If you want to turn your MHz-mc3030 into a 2,4 GHz version und might use the genuine MULTIPLEX sytem M-LINK. Only the HF-module is no longer in production and only by chance available on eBay. If you want to extend the TX to telemetry you need the telemetry display which also is no longer in production. You might use the M-LINK Souffler which announces telemetry data, but no longer in prodution. Your TX is to old!
So M-LINK is no real option for your mc3030 anymore. You might look for a Duplex TU2 module and a Jeti-Box that could be a solution.
