[aprssig] N7RIF contact info?

[Lynn W. Deffenbaugh (Mr)]

I'm familiar with the dual-meaning of Mic-E.  What I'm tracking down is 
the apparent telemetry (`XXXX) that is appearing in those packets.  I 
see the teletry defined at 
http://www.tapr.org/kits_mic-e.html#message_format just as promulgated 
in aprs101.pdf.

I pulled the mic-e.manual.pdf file from that site and I now see on page 
18 that it DOES in fact support telemetry!  And that telemetry is 
inserted before any status text in the packet.  This is exactly what I 
needed to know!  (Oh, and apparently N7RIF-9 is configured to transmit 
just 2 values, the first of which is a measure of the input voltage).

Thank you for the pointers to home in on the final answer.
