Here are a couple of modifications/options for the New Yaesu FT-5200
Dual Band 2M/440 Tranceiver.  
     
     To expand the RF coverage so you can take advantage of MARS/CAP or 
service uses follow the steps provided.

****** CAUTION * * Follow proper ESD procedures to prevent Electro-Static 
       Discharge damage to semi-conductor components! *******

     a.  Remove Power.
     b.  Release and remove the front control head from the radio.
     c.  Remove the six screws from the top cove and the six screws from the 
         bottom cover.
     d.  Carefully remove the top and bottom covers (careful not to drop out
         the speaker).
     e.  Remove the two screws and front control head mounting plate from 
         the radio.
     f.  Locate solder pads 1 - 7 (Standard jumpered pads are 2 and 7 only)
     g.  sing a low wattage(30-40W) soldering iron and good electronic grade 
         rosin core solder, Solder jump pads 1, 3, and 6.  (Now pads 1, 2, 3,
         6 and 7 are jumpered)
     h.  Reinstall the front control panel mounting plate.  
     i.  Reassemble the radio.
     j.  Connect Power.
     k.  Press and HOLD [D/MR], [F/W] & [REV] keys and turn on the radio.
         (The display will show 000.000 and 300.000) 
     l.  Set the VHF transmit and receive limits as follows:         
          
          Enter 118.00 MHz and press [D/MR]    (VHF Rx Low)
          Enter 174.00 MHz and press [D/MR]    (VHF Rx High)
          Enter 140.00 MHz and Press [D/MR]    (VHF Tx Low)
          Enter 174.00 MHz and press [D/MR]    (VHF Tx High)

     m.  Set the UHF transmit and receive limits as follows:

          Enter 420.00 MHz and press [D/MR]    (UHF Rx Low)
          Enter 475.00 MHz and press [D/MR]    (UHF Rx High)
          Enter 420.00 MHz and Press [D/MR]    (UHF Tx Low)
          Enter 475.00 MHz and press [D/MR]    (UHF Tx High)
          
     n.  Press [Function] then [REP] and select 5 MHz for UHF band
         Repeater offset.
     o.  Press [Function] then [REP] and select 600 KHz for VHF band
         Repeater offset.
       

That completes the modification for extended RF coverage of the FT-5200.
NOTICE!  A license from the applicable service is required to operate outside 
the normal ham bands (i.e. MARS or CAP).

 --- Other items of interest for users of the FT-5200 ---

 - Overriding the automatic display dimmer...

     Press and HOLD [MHz] and turn on the radio, then use the channel knob
     to select the desired brightness.

 - For expanded Receive in the VHF band (no change in transmit coverage)

     Press and HOLD [DVS] & [MHz] keys and turn on the radio.



I have made the previous modification to a unit and have not had any problems 
what so ever.  I assume NO responsibility or liability for any damage or 
violation resulting from anyone else making these modifications or operating 
in a portion of a band for which the user is not properly licensed.
