Extended Frequency Range (5200):

	[ed - yes, there are two mods and I include them both since
	they are so different in style (and perhaps content).]

	Effect: set receive and transmit range.
	Bad effect: ARS gone.

	The following explains how to expand the receive and transmit
	frequency range of the Yaesu FT-5200 and how to enable the cross-
	band repeater operation.

	All the modifications are carried out on the interface board and
	involve removing or adding links on jumper spots.

	You will get considerably increased receive and transmit
	coverage; however, you will lose the Automatic Repeater Shift
	(ARS) feature.	You may think this is an acceptable price.
	Finally, it should be obvious,	but during this procedure you
	will obviously lose any stored memories.

	1) Remove the control head and set on one side
	2) Remove the upper and lower covers on the main chassis.  For
	   convenience, remove the speaker, noting which way the two
	   pin pcb connector is oriented. [ed -- does it matter?]
	3) Remove two side screws holding on the front of the chassis
	   and remove chassis front.  (The chassis front is the
	   surface with the contacts for the control head.)
	4) Locate a double row of ten by two jumper spots, numbered 1
	   to 20.  The jumper configurations will depend on the area
	   for which the rig was intended.  Note the arrangement if
	   you ever want to un-modify your radio.
	5) Using a fine-tip soldering iron, set the jumper spots as
	   follows:

	           1    closed
	           2    closed
	           3    closed
	           4    open
	           5    closed
	           6    closed
	           7    closed

	6) This completes the alteration for frequency expansion.
	   Reassemble the radio.
	7) Reinitialise the radio by simultaneously holding D/MR, F/W,
	   REV and POWER.  You must now program in the band limits.
	   The display will show a blinking "1" in the left-hand
	   memory box and "000.000" in the left-hand frequency
	   display. (Ignore the right-hand display for now).  The
	   following limits are suggested, but the RF circuitry of the
	   rig will only cover slightly less.  Use the dial or up/down
	   buttons to select the frequency and then press D/MR to
	   store it.  The blinking "1" will increment.

	   VHF rx:  137.000   174.000
	   VHF tx:  137.000   174.000
	   (display will show blinking "1" and "300.000")
	   UHF rx:  410.000   470.000
	   UHF tx:  410.000   470.000

	   (Note: it is possible to set the RX limits wider than the
	   TX limits; for obvious reasons you cannot have the reverse
	   situation).
	8) You can repeat step 7 above at any time if you need to
	   change the limits.
	9) The pre-set repeater offsets are now no longer available
	   and you will have to set them up manually using the
	   instructions on page 16 of the manual.  The Automatic
	   Repeater Shift (ARS) feature (also on page 16 of the
	   manual) will also have disappeared and you will have no way
	   of getting it back (except by changing the jumpers back).


	   To enable the crossband repeat, remove the link at
	   jumper spot 17. (Note, just below jumper spot 17 is a
	   separate jumper spot,  not part of the group of twenty -
	   leave this alone).
