7.4.13 Noise Squelch
(a) Adjustment rang 6-26dB SINAD
(b) Attack time 20mSec. Above 20dB Quieting
(c) Release Time 150mSec. At 20dB Quieting decreasing to 20mSec. Above
2uV preset threshold

7.4.14 Carrier Level Squelch
Carrier level squelch can be used when it is necessary to set the opening point above
26 dB SINAD as may be required in link applications. The minimum adjustment range
is 0.5 to 200 uV.
7.4.15 Receiver Frequency Spread
Less than 1dB change in sensitivity over the band
