for Ham Mod remove the lower left diode (d14)from the pcb behind the lock button.

it looks like this:

[d12] [d13]

[d11] [d14]

for TX expansion you have to leave (d11) intact

and take the diode (d14) that you removed and install it at (d13).

if the diodes are all gone and no original diodes can be obtained normal
1N4007 diodes or simmilar can be used







or with original diodes:
