[R-390] SSB Conversion Photos

[Jim DiMauro]

Dennis, Federico, Les & the Group:

Thanks to all for your responses and information on the SSB mod.  I'm
looking forward to seeing the EAC schematic, since it seems to be the type I
have.

Federico: my panel is silkscreened.  Dennis: the VFO vernier is electrical;
the control that replaced the dial lock is an air-variable capacitor,
connected to a line that seemingly connects to the PTO.  I didn't trace it
carefully.

73 to all,

Jim
