1130.0. "Futaba FG question" by SHTGUN::SCHRADER (CSS::SCHRADER=264-4170=MK01/2K12) Mon Oct 16 1989 09:50

I've got an 3-4 yr old Futaba FG AM radio. The kind with the removable
RF module in the back. Does anybody know if there are any FM modules that will
work in this radio? The current Futaba ads show the FGs as AM only but other
of their transmitters use what looks like a similar module. Is it too much to
hope for that they are compatible??? Right now this radio's reciever is an old
single conversion AM. I could just go with one of those $60 Polk double conv.
AM recievers but if i'm going to upgrade this thing then i'd rather go to
FM while i'm at it.

While in Reno this last summer, I stopped in a hobby shop where
the owner showed me the similarity between the Polk/Expert radio
TX module and Futaba.  The outside design is the same, and
they are mechanically identical.  To be honest, I know that I
must have asked him if the module would work, but since I'm not
interested in either the Aristo or Futaba, I don't remember the
answer.  Anyway, you might check it out by taking your radio to a
shop and trying the modules.

    Good question, I have an AM Futaba FG also and would be interested in
    the answer.  I'd be surprised if the FM module were compatible...
    Futaba didn't make the connectors compatible from AM to FM, probably
    to force people to buy new servos for their FM set.
    
    Then again, maybe the modules _are_ compatible, but cost $150.

    If you think about it the jap's radio's marketing position clearly
    indicates that they don't want to be in the loose piece business.
    They are probably set up to build and ship systems. not the 
    individual pieces of the systems. For me it just doesn't make 
    sence to buy servos and RX's unless your buying a computer system.
    When the system costs 800.00 it's actually cheaper to buy one system
    and then flight packs. Flightpacks cost you app 400.00 . But then
    thats cheaper than 800.00 for a second system. If you need that
    kind of system then it's cost effective. For the avg. sport guy
    I cannot see buying any system greater tha the 7UAP's or similar
    that futaba sells. they give you functionality for under 300.00.

1130.4FM not the answer if not dual conversionLEDS::WATTTue Oct 17 1989 22:2011
    If the FG is available in FM, I would make darn sure that it includes a
    Dual Conversion Receiver (Narrow Band).  If not, it will most likely be
    more prone to interference than the AM.  The older FM receiver designs
    seem to be pretty bad.  I know a couple of guys that sent them back to
    be converted to AM.  Anyway, don't assume that FM is better than AM.
    The newer FM receivers are very good because of dual conversion which
    makes them immune to some of the image problems that single conversion
    receivers are having.
