[aprssig] KPC Telemetry clarification

[Daron J. Wilson]

We're also working with this and learning.  Here is what we did to take
advantage of the telemetry features.  We've got these on three sites
now, three more to go up next month.

It seems to work pretty well so far.

Subject: [aprssig] KPC Telemetry clarification
 
I've been playing around with the Telemetry feature on my KPC-3's. 
 
I guess I just need clarification on a few things.
 
Inputs AN0 and AN1 have a factory installed 10K Ohm resistor in series
with there respective input pins. I need to install a 2.4K Ohm resistor
across the input and ground (I actually use a pot at 2.35K Ohms
connected to the allocated pads on the PCB).
 
For AN2 AN3 and AN5 I need to install a 10 K Ohm resistor in series as
well as the 2.4K Ohm resistor across the input to ground.
 
Does this look right?
 
Thanks!
Ryan
