Peak to Average performance of speech processors. SSB

savings pushing $600 (even more with the KRX3).
2. See comments below by N6WG. I've already installed
several mods including two using SMD parts. Eventually
a Service Manual is also promised.

Can anyone give me the shape factor for the

I was hoping Wayne might respond since we
