9600 Mod for FT-708-R

Hello Ham's,here is the modification for use the FT-708-R with a G3RHU modem
for 9600 bd packet operation.


       Audio output from FT 708 R receiver's Discriminator for 9600 bauds

                           -------------------------

Here is a very simple way of taking audio direct from the discriminator.
Connect a flying lead to pin 9 Q 107 (MC3357P) that is located at the opposite
side of the CPU.

You can also take the signal from the GREEN cable that goes to the TONE SQUELCH
optional unit.


           TxAudio input into FT 708 R Varactor diode for 9600 bauds
           ---------------------------------------------------------

You must find the D 209 Varactor diode (FC 53) locate near the output DC
connection,or near the VR 202 trimmer in the PLL Unit.Then you must insert the
TXA signal in the catode of D 209 and the 9600 modification is made.


My FT-708 can run 9600 operation very well with a TX DELAY value of 17.
