- GENERAL COVERAGE TX
- This is real simple just cut R34 on NB SW board behind front panel.
- Now the set has general coverage TX as well as RX.
-
- RTTY RX NON STANDARD LOW TONES
-
- Parts required:
- 1x LS104 coil
-
- Remove top lid of screening box around X5 X6 etc in the centre of PCB.
- Unsolder the short earth strap between X5 and L35. Resolder this between X5
- and side screen.
- Remove 11 PCB securing screws and hinge the PCB from left over LHS of set.
- Unsolder screen beneath area of X5 etc.
- Remove L35 "LS93A"
-
- Take LS104, cut the centre leg of the three on one side and orientate it into
- the PCB so that the two remaining legs go into the two holes in the PCB not
- the three. Solder in place, solder back the screen, replace the PCB and the
- screws.
- Switch on the set give a few minutes to warm up, connect a freq counter via a
- 470ohm resistor to cp1 and with the set on RTTY RX, adjust the new coil for
