Topband: Receivers

[VR2BrettGraham]

As an IC-765 is a 751A in a bigger box with tuner & the same internal
power supply, the 765 adds essentially bigger knobs & 10 cycle
frequency display.  I believe 751As can be had now for around US$500.

Quite a bit of commonality in receiver circuitry across ICOM's product
line back then, starting with the IC-730.

This makes me wonder if I should have ever gotten rid of my IC-740 -
ham bands only & perhaps with a change of first IF filter... but how to
add computer control?  The 730 didn't have topband.

Wonder if a PIEXX board could be put into an 830?  Some more drastic
surgery to get rid of the valves in the transmitter & that would be the rig
to have, IMHO.
