Subject: [aprssig] solutions sought for monitoring idea

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

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?
