8525 & 8528 LSB Option
This Option is fairly straight forward and can be accomplished by most people.
By adding the crystal (Z3 1647KHz) to the RF Mixer - Dual Synth board which is
located under the top (smaller) grey lid. Removal of this board is required to solder
the crystal in place. Once you have reassembled the radio and the crystal has been
allowed to cool, switch the radio ON, select a channel that has been programmed
for LSB, using a frequency counter press and hold the "TUNE" button and adjust
C162 to frequency using an insulated tuning tool. If there is not enough adjustment
you may be required to change the value of C161 and try adjusting C162 again until
you are as close as possible to the correct frequency.
Always refer to your "Service Manual".
NOTE:- Reprogramming the eprom for each channel is requires for LSB operation,
or you could use the "P" channel option if you have the link and a TXE eprom already
installed. Make sure when the crystal is soldered in you also include the earth wire to
the outside can on the crystal.
