I like the SSM2167 for one big reason: Simpler package. While QFN is easy to do in a mass-production environment and I've never even had a problem with my hot air station, I hate QFN's/ TDFN' (Tiny Damned Frickin No-leaded packages) when doing prototyping or small quantity stuff.
For the first run of this PCB, I'm sure there will be problems, and being able to probe the pins directly is always nice. It's an extra dollar in low quantities, but the compression part is nice. I added it to my design, made a few changes, so I should be pretty good to go with this first revision.
That said, in my many many years of making circuit boards, I have had a design work and fit_exactly_ as intended and specified only once in my life. It was quite the celebration! With this particular system, I'm sure there will be no exceptions to my rule that there's always a revB :)
Moved mic/speaker output headers outwards by 0.2" to make front panel mating better
Added SSM2167 mic amplifier, variable resistor for gain, adds speech compression (1:1 to 1:10)
Other features not stated earlier, S-meter and SWR measurement.
Here we goooo......
