Help notes on the FT107 - FTV107
                   ================================

** This rig does not have any real known stock faults, probably because it
was not sold in great quantities. It is very difficult to service the FT107
if you do not have the correct extender boards and the required extension
cables, because the boards are mostly inaccessible when they are plugged in.

CB DE-MODIFICATION : I have seen a couple of units which were converted for
CB, however it was a hit and miss affair due to the difficulty in aligning
them without the extenders. It is highly recommended that you should avoid
converting them back if the extenders are not available, as re-alignment is
essential and this cannot be performed with the boards in situ.

TX BREAKING THROUGH ON AUDIO STAGES : Solder a 10nF capacitor between the
base of Q02 (on the IF motherboard) and ground.

MOD FOR 434-436 TX IN SAT 2 : This modification makes the FTV107 transmit
over 434-436MHz when SAT 2 is selected. Cut the connection between D09
cathode and the band change switch, then connect D09 cathode to the cathode
of D012. Both diodes are located on the rear wafer of the bandchange switch.

NO RX ON 2M : Check RF amp and mixer. Check R38 and D16 as these may be burnt
out if the user connected the unit incorrectly.

NO 2M TX : The PA module in this is pretty reliable, but I have twice had
failures.

RX CUTS OUT WHEN BAND IS CHANGED : There are three CMOS ICs type 4066 (or
4016) mounted on a small PCB on the right hand side of the unit. If one or
more of these ICs are faulty then this fault can occur because these ICs
select the xtal in the transverter local osc, and when they fail they try to
select two or three xtals at the same time.

USING FTV107 WITH THE FT102 : It is not unusual to use this transverter with
the FT102. The plug that normally goes into the ACC socket of the 107 will
need to be cut off. The lead will then require a suitable DIN plug for the
102. You can use the manuals to identify the correct wiring for the PTT line,
but it will be neccesary to connect an external 12 volt supply to the
transverter lead. The panel lights in the transverter require an 8 volt
supply - these can be made operational by connecting the transverter's 8 volt
wire to the 12 volt supply via a 27 ohm 2 watt resistor.
