    Dear John,
    (That sounds good!)

    Anyone know if this can be done simply?

    (There must be a few 35Mhz receivers of limited use abou the place now. Mine is fairly recent and cost quite a lot of money.)

    Converting a 35Mhz dual conversion receiver (Futaba) to 40Mhz Empty changing 35mhz to 40 mhz fm

    HI David
    It is strange that you have asked this because i have just changed this week a 35 mhz futaba receiver to 40 mhz fm, for some thing i wonted to do in most cases the osillator for the 35 mhz crystal will retune to 40 mhz with no modes but you will have to change a couple of caps to a smaller value on front end of RX input and retune to 40 mhz can be done in ten mins

    Converting a 35Mhz dual conversion receiver (Futaba) to 40Mhz Empty Graupner 40MHz Radio to Synthesized 75MHz

    Post  Giovanni LiCalsi on Mon Jul 18, 2011 4:34 am

    Across the pond in the USA we use 75MHZ for submarine use and I am converting a Graupner 40MHz radio to this frequency. The RF module, that I am using, is a HiTec Spectra Synthesized 75MHz RF.I'm wondering if there is a twin-stick, similar to my Robbe Nautical F-14, available to convert this radio?
    Kind regards,
    Giovanni

    HI Giovanni
    You could try converting a FC-18 ROBBE FUTABA as i reworked one to work on 458 mhz to use in uav plane its a pitty you guys in the U.S.A use 75mhz would be better off on lower bands, what sort of power level are you allowed to use in the UK it is 100mw ERP

    Hello John,
    It seems that the mv limit is a mystery in the USA!
    Just type into the www.RCgroups.com search box and be dazed and confused!
    Please show me the Robbe FC-18 twin-stick conversion? I'm dying to add this to my Graupner MC-19.
    Regards,
    Giovanni
