I measured the bandwith of my Microire receiver. Test method was to
set the receiver squelch just above trip point then to sweep an rf
generator across the set frequency. The points at which squelch
tripped were recorded from the frequency counter built into the rf
generator. Results for the Microire and for an STS handheld were as
follows:


VHF Comm. Measurements 12/16/03

MicroAir:

Pass-band for squelch trip 123.2930 to 123.3070 = 14.0 kHz

STS:

123.2879 to 123.3121 or 24.2 kHz

This appears to confirm the speculation in an earlier thread that the
Microaire receiver has a narrow bandwidth and will be less tolerant of
off frequency transmitters.

I won't know if this explains the audio distortion heard when
receiving some transmitters until I can do a check on the transmit
freq of those units.

I really fat fingered that post. It should read Microair.
