[arm-allstar] The Quantar and AllStar

[Justin Reed]

Bill,

This is completely off topic for this list, as it centers around the 
Quantar, and not hamvoip.

Shooting completely from the hip here, but I'm guessing that problem #1 
is that the Quantar is capable of passing P25 end-to-end, but 
encoding/decoding P25 at the Quantar itself is going to require an 
option card that likely isn't present in your station. I never worked in 
a motorola shop, but in the GE shop where I did work, the Mastr II and 
Mastr III stations required different hardware depending on whether you 
were repeating VoiceGuard or encoding/decoding voice guard at the 
station (as a base station).

So, the first question is, do you know with 100% certainty that your 
Quantar is equipped to encode/decode P25 as a base station connected to 
a 4 wire audio line and console/remote? More specifically, can you 
inject analog voice audio into the station and have it come out as P25, 
and does the station receive P25 and convert it to analog audio?

73,
Justin
