Signal to Noise Ratio (dB):
Note: The dual envelope "soft" limiter provides
exceptionally good handling of transients using
variable attack and release time constants.
Once activated, the limiter compresses 30+ dB
of transmitter input range into 4.5 dB of receiver
output range, thus reducing the measured figure f
or SNR without limiting by 4.5 dB

The FCC requires that the following statement be included in this manual:
This device complies with FCC radiation exposure limits as set forth for an uncontrolled environment. This device
should be installed and operated so that its antenna(s) are not co-located or operating in conjunction with any other
antenna or transmitter.

Dual bi-color LEDs indicate modulation of –20, -10, 0 and +10 dB referenced to full modulation.
–12 dB/octave; 70 Hz (35 Hz for UH400TM)
Control panel knob adjusts audio gain.
Rotary switches on bottom panel adjust transmitter frequency.
