[App_rpt-users] RX Input Adjust Failed

[kk6ecm]

Thanks! Part of the problem was my lack of understanding.

OK... have everything working, but having difficulty understanding the tune
function.

radio tune rxnoise
tune rxnoise maxtries=12, target=23000, tolerance=2750

radio tune rxvoice
target=7200 tolerance=360

I'm passing the rxvoice, but failing the rxnoise. The radio seems to have a
lot of noise, however the measured is a small fraction of the modulated
signal. But the target for the rxnoise is 3 times the level of the
rxvoice... I expected the rxnoise to be much lower than the rxvoice levels,
comparable to what I'm measuring. IaxRpt is "measuring" a lot of noise (gree
bar is showing strong. What am I missing here with respect to these
measurement in the tune? What are the units? Gain? Where rxnoise would
require much more gain (target?) than the rxvoice to achieve some level?

Thanks,

Bob,

What is the squelch logic coming out of your radio?

If the line changes, does it go low with signal or no signal? And when 
it goes low does it pull to ground?

The URI will not see a signal change if only voltage is supplied by the 
radio. The radio MUST pull the signal to ground on receive or when 
squelched.

If the radio doesn't pull to ground then you may need to connect an NPN 
transistor to pull the line to ground. Then set USB radio for usbinvert.
