| The Midland 77-120 ESP
CB radio represents the state of the art in high tech
engineering. This unit is not only a full feature CB transceiver but
incorporates a high performance 10 channel NOAA weather bureau VHF
receiver. The full 10-channel weather receiver allows use on all
current and future NOAA weather bureau channels plus Canadian and
international channels. The unit incorporates microprocessor
controlled PLL circuitry for precise tuning and increased function.
Receiver noise and interference can now be largely eliminated by the
new ESP2™ noise reduction system. Also included is a back-lighted
Liquid Crystal Display (LCD) digital information center that out-dates
CB’s with LED readouts.
- Switch-able
ESP 2 for up to 95% noise reduction
- Front
firing speaker for better sound
- 7
channel US weather receiver
- Large
LCD display with choice of frequency or channel display
- 7
segment signal strength and power output meter
- Instant
channel 9 access
- Variable
Mic gain to boost transmission audio for maximum range
- Variable
RF gain control (Local/DX) to prevent overload from nearby CBs
