Are you out of model memories? you might consider the JR 622 which would
maintain your compatibility. I've heard good things about the 622, just that it
doesn't have all the mixes.

Jim (saving for a 388 sometime this season)

    My biggest question would be, can you use that version of the RCD
    receiver with your X-347 if you wanted to??  I seem to remember that
    the Hitec is a Futaba variant...
    
    I have flown a couple of planes with the Prism 7...  It just doesn't
    feel as solid in your hands as a JR..
    
    But, as long as the flight systems are compatible, then it would
    be a reasonable thing to do..
    
    cheers,

    Jim,
    
       I am out of memories in the X-347 and I need a second radio so I can
    be towed up with my gliders.  Right now my towplane and gliders are all
    on the X347.

    Jeff,
    
        Thanks for pointing out this compatibility issue betwwen the Hitec
    and JR receivers.  I do want to be able to use any of my RX with any of
    my Tx's.
    
    The JR X622 is looking better all the time!  I should be able to put
    one of my gliders on the 622 which will free up another memory on the
    X347.  The $120 savings will buy another RCD & channel rx and a couple
    517 servos.
    
    Sure would love a X388, but I've got a Discus coming and need to buy a
    Moki 1.8 for my new towplane.  This should completely wipe out my '95
    R/C budget!  The sailplanes my friend Robin is bringing in from Germany
    are just too good a deal to turn down - even if I can't afford one!
    
    Thanks again!
    
    
    Regards,

This sorta means two different channels so using the Rx with the other Tx
requires a crystal change.

You might consider a JR Max4 FM which gives you another JR Rx for about $120 and
includes the battery, switch and servos along with a Tx that can be used as a
buddy box with the 347 (this is what I did).

Jim (the combinations are endless)

    I purchased a JR XF622 radio today from, of all places, a local hobby
    shop! I paid $259 + tax.  This is as low as any price I saw advertised
    from the big discounters in the latest RCM magazine.  With sales
    tax(8%) it came out about $10 higher than the lowest mailorder price
    would have been when you add $5 shipping.  It actually felt good to buy
    a "big ticket" item from a local hobby shop.
    
    The radio itself is real nice.  It has that "JR feel" that is hard to
    describe, but you know it when you hold one.
    
    One R/C purchase down - 2 more to go this year and those are both
    decided already - Moki 1.8 and Discus glider.
    
    

    I too will be buying a new radio this week. Im looking
    to pick up a 6 channel and Im leaning twords the Hi Tec
    brand. An earlier reply asked if anyone had any coments
    on this line of radio, I didn't see a response.Is there anyone
    out there using one? Has anyone read any reports on them? On
    a different subject, does anyone know if Toms hobby corner in
    Chelmsford is still doing buisness? Thanks for any and all help.
    
    
                                     Jim

    I recommend the JR XF622, which I purchased.  It "feels" much better
    than the Hi-Tec and is very easy to program.
    
    There is an outfit in Washington selling them for $239 + $10 shipping.
    This is the best price I have seen.
    
    IMO you cannot go wrong with a JR radio.  Great performance at a VERY
    reasonable price.

Tom's is still alive and well. What gave you the idea he might not be?

    Many years ago, I thought I heard talk of him selling the buisness.
    I myself haven't been active for about four years. I just sent off
    my A.M.A. application today. I'd like to keep the price for a new rig
    under 200.00 if I can, if not, I may end up with a another four chn.
    which is all I need at the moment but, Im planing for the future
    by trying for a six. Thanks for the info.
    
                                                      Jim

Tom is like Ray in Worcester, they both talk about selling the business but
would be hard pressed to give it up. Tom has a couple of people working the
store for him now and isn't involved in the day to day too much. That has
probably freed him up enough to keep it going. I did see one of the Hitec
programables at Rays and it looked pretty featureful. Don't know wnyone that's
using one but they make the RCD Rxs which I've used quite a bit and have been
pleased.

Jim

    I got another question while I have someones attention. Do radio
    manufacturers still make AM. radios? If so, why has FM become so 
    popular. For the guy just out to burn up some fuel, is there really
    a nesecity to go FM. Im basically a sunday flyer, I don't need anything
    programable.
    
                                                   More thanks, Jim

Do you drive to work or bring your lunch? 8^)

FM is a better encoding method than AM. Note how FM radio stations come in
better than AM ones both in distance and interference (driving under a bridge)

FM doesn't imply programmable radio and there are AM programables out there (ACE
MicroPro 8000)

FM changes the frequency around a central point while AM changes the strength of
the signal. FM can still be decoded for weak signals while I assume that AM has
some threshhold where it wouldn't see the change. Hopefully one of the hardware
people can chime in and correct me if I'm wrong.

Jim (software type)

    Yes, AM is more susceptable to noise because it's information is
    transmitted as a varying amplitude.  The problem is that noise shows up
    as amplitude spikes which clouds your information.  FM, however,
    doesn't depend on the amplitude of the signal and thus is a safer
    method.

Well - I dissagree with Jim and Andy but the results are the same.
I also would advise an FM radio because there are VERY VERY VERY few
dual conversion AM receivers available (I have some).

The most common AM radio around is the Futaba Attack and it only
has a single conversion receiver - not recommended.

Now that your back - take a deep breath and spend another hundred
and get a programmable system - Most of this notes file would vote
for the JR347 or JR348.  They are wonderful radios and you will
never regret that extra $100.  And I am not bias - as I am
not a current JR owner, but I have been in the past and do own
3 programmable radios (one AM).

    Well,
              I stopped in to the R/C buyers warehouse in N.H
    wednesday night and bought the new futaba skysport 6va. for
    199.00. They had a 6CH conquest for 6.00 dollars less but it
    doesn't have the features of the skysport. Its gonna take some
    time to understand all the funtions, funtion Im sure I woun't
    need for a J3 cub, but wiil probably come in handy on my next
    ship.
    
                                                        Jim

I saw that at Ray's in Worcester and thought it looked pretty good. If I
remember correctly, it had some mixing capability??? If so, it was definately
worth the $6 more. I did get to hold the Tx and it had a pretty good feel,
similar to the JR X-347

Jim

    Jim,
    
    	I'm not really familiar with the Skysport but you'll probably be
    surprised at how useful the functionality is. On the cub, you'll want
    to have the ailerons and rudder mixed. You can do this with this radio
    and "I think" switch it in and out. When your setting up your controls,
    you'll find it much easier to just push a button to get those ailerons,
    rudder, elevator, and throttle all set just right instead of having to
    un hook the clevis a dozen times before it's right. I think you'll
    enjoy it.

As I recall from the radio I handled, they were still using pots and switches
inside a back panel for the mixing. Might have been a different radio since I
looked at the Hitek at the same time.
