I finally found the T/R delay mod for Rock-Mite. Thanks to all who send notes, etc.

Here is a summary of locations for a variety of RM mods:

Delaying the T/R switching to mask the squarish audio on the sidetone:

Reducing the overall volume of the sidetone:

Adding receiver gain control:

Filtering the sidetone (the "ten-ten" mod):

Replacing the 2N2222 for more output:
