- 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.... you're
- 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.

- 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)
-

-
- 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???

- Dual Bander YAESU FT-5200 Modifications for wideband RX/TX VHF/UHF coverage
- and Cross-band Repeater operation.
- ===============================================================================
-
- First locate the 20 jumpers on the control Unit of the FT-5200.
- Then short jumpers 1-2-3-6-7 .
- Some jumpers are still shorted depending upon the country version.
- Remove the Jumper number 17 for cross-band operation .
- For resetting the unit press D/MR -- F/W -- REV buttons in the same time
- and switch on the transceiver.
- The display must show now 300.000 on the right and 000.000 on the left .
- You must now program the lower and upper bands limits on RX and TX as follows:
- After resetting the channel number digit on the left of the display is
- showing a ""1"" blinking ..
- With the vfo knob and the MHZ button increment from 000.000 to the desired
- lower VHF frequency with 1 Mhz steps . The press the D/MR button to lock
- the frequency . Now the channel digit shows a blinkin""2"". Increment
- the display to obtain the VHF upper limit . Press again D/MR to lock the
- frequency and obtain a ""3"" digit channel blinking .. Increment the display
- value with the vfo knob to fix the TX VHF lower limit . Push D/MR to lock
- the frequency . The digit channel is blinking with number ""4"" and program
- the upper TX transmit limit . Press again D/MR , the display is now
- reversed from left to right and program the UHF TX/RX limits with the same
- procedure used for teh VHF band.
- ------------------------------------------------------------------------------
- For cross-band operation , press the RPT button when swithching ON the
- tranceiver . Adjust the audio level with the volume control and balance .
- ------------------------------------------------------------------------------
- For wideband Uhf RX operation the frond end coils with metallic cores
- must be realigned to spread the sensitivity of the receiver. A swept
- oscillator with scope should be employed eventually .
