I'm interested in setting up some sort of logging system that does the
following:

Records timestamped packets received over the air
Records timestamped positions
Records signal levels
Potentially down the road, records the off-the-air audio for later analysis
(i.e. looking at collisions)

A standard TNC and a GPS could probably do the first two, trivially, by
just spewing the two serial data streams into a text file

The third one (levels) is a bit trickier.

So, I've been thinking along the lines of a PCR1000 (which can provide
level over the RS232 interface) and a software decoder of the packets,
possibly with some way to shoot the data (when the receiver unsquelches)
into WAV or AU or raw files.

Any other ideas?

Jim, W6RMK
