CYBERNET.1
                              Final Transistors
                       ----------------------------

   Replace Q9 with 2SC1306 / replace Q10 with 2SC1307 fpr 10 watts OP
   Original transistors will give approx 5 watts OP


                               PLL Alignment
                         -------------------------

   Test gear required
   -------------------
   Freq counter to 60 Mhz, Digital VOM, 15Mhz CRO

   For 50 Mhz only....earth pin 4 of PLL 02A for 5Khz steps
   Connect counter at TP2 through 1000pf cap and adjust CT3 for 10.240 Mhz

   Connect CRO and counter at TP3 and adjust T3 for max amptitude.
   Counter should show Xtal freq  X2 ( USB only )
   Set clarifier at mid position
   Adjust CT1 and CT2 so that TP3 reads 21.95272 approx on counter 

   FREQUENCIES AT IC2

   Pin 4=21.95272    reference osc input
   Pin 2=19.40272    vco input
   Pin 9=2.55 approx loop error signal


                               VCO Alignment
                      -------------------------------

   Connect VOM to TP1 and adjust VCO slug for the following.....

   40 Channel    10 khz spacings   CH1   2.8-3 volts
                                   CH40  3.8-4 volts

   40 Channel    5 khz spacings    CH1   2.0 volts
                                   CH40  2.8 volts
   (Voltages not critical)


                             Receiver Alignment
                     -----------------------------------

   Peak   T7 T8 T9 for max received signal
   Peak   T1 T2 T3 for max sensitivity


                            Transmitter Alignment
                     ------------------------------------

   Align on USB only.....Adjust T4 T5 T6  /  L7  L11  L12  L13  for
   max. power OP.

   NOTE   If set oscilates in TX with no audio mod applied, go back and
   re-adjust T4  T5  ( reasonably critical )

   Check for equal OP on CH 1 and CH40

   Adjust RV 2  full on  ( ALS )
   Adjust RV 11 Full on  ( ALC )

   Output should be 4-5 watts or 8-10 if finals have been changed as
   previously described.

   Check for carrier leakage on power meter when mic button pressed with no
   modulation. If leakage is present adjust RV4  RV5 ( carrier bal )

   NOTE    USB and LSB are reversed for some reason ?
           Swapping wires on pin 19 and 20 will cure the problem.
           ie...purple and brown wires from mode switch.

   Check adj. of T1  T2  T3  for max power OP or RX sens.

   Slight adj. of CT4  CT5 may be made if required to shift the IF freq.
   for clarity of RX audio.

   I have modified two radios for both freq and they work well.
