- 2016A.1
- PARTS: 2 small diodes, not at all critical; 1N1004s are fine
- 1 small junk-box capacitor, .01 to .1, maybe tant or
- electrolytic
- abt 6" of hookup wire
-
- PROC: -Cut the wire that goes from P24 on the main board to P9 on the
- synthesizer board and install a diode in the wire, with the
- cathode towards the synthesizer.
- -Connect the cathode lead of the second diode to the cathode of
- the first.
- -Connect the anode lead of the second diode, via the hookup
- wire, to P39 on the main board. (You can tap into the
- white/orange wire that goes from P39 to the display board. You
- guessed it -- this is the lead that drives the XMT LED.)
- -To the same junction, connect the + lead of the cap; connect
- the - lead to a good ground on the synth board. Your choice of
- grounds, but the emitter of Q12 is OK, as is almost any other
- reasonable shield, metal, or board screw. (If you couldn't
- find a ground, would you be a ham?)
- -Of course, all the standard good techniques (power off, good
- insulation, appropriate soldering iron and temperature, etc.)
- should be used.
-
- Another mod that suggests itself on this radio is the replacement of
- toggle switch SW6 (the red-handled WRITE switch) with a momentary.
