FT5200 cross band mod
Fm: Tony Lessing KA3KVD 76474,2051
I finally got the mod for the FT5200 cross band mod. It goes as follows:
1. Disconnect DC power from radio. 2. Unlatch and remove the front control
head. !Do not take apart the control head or the warranty will go *VOID* :-)
3. Remove (6) screws from top cover of radio. 4. Remove (6) screws from bottom
cover of radio. 5. Remove top and bottom cover.. being careful of the speaker
that will want to fall out. 6. Remove the (2) silver screws (on each side of
radio) holding front control head mounting plate to main body of radio. Remove
the front mounting plate. 7. Locate and unsolder jumper pad 17. 8. Install the
front mounting plate, and top and bottom covers. 9. Reconnect power.... your
ready to go..
10. To put in xband repeat press and hold the RPT key while turning on the
radio. To stop... turn off the radio.
!! note !! It is suggested to disconnect the mic when in xband repeat, as it
will be "hot". Adjust the volume knob for the desired repeat audio level.
I will be ripping into the unit over here later in the week and will report if
any "anomolies appear".

Regarding .... Jumper Pad 17 ....
This might seem confusing when first viewing the jumper pads... they are to
the right of the 5_strip connector for the face plate and are numbered as
follows
.. 20 18 16 14 12 10 8 6 4 2
.. 19 17 15 13 11 09 7 5 3 1
You will see that the number 17 is lower than the rest and that there are 2
pads above it... one in line with all the others (this is the correct one) and
one that is horizontal and just above the number "17" (this should be left
alone)
BTW I couldn't wait and just completed the mod.... everything works as
advertised. It sure is a *tiny* world to work on in there tho :-)

I tried it...it works!
It is a bit rough cross-band repeating two repeaters (hardly efficient use
of spectrum, now isn't it? (Honest..just testing)
Also, there are certain frequency combinations that just don't work, and
others that require one, the other, or both sides to transmit at low power.
Nice toy...now, a practical application???
