Maxon SD-125EL-V2 + SD-125EL-U2-FSKHD15 Data Radio with FSK Module Modification and HD15 Connector; 148-174 MHz
**Maxon SD-125EL-V2 + SD-125EL-U2-FSKHD15 Data Radio with FSK Module Modification and HD15 Connector is a custom built solution**
The Maxon SD-125EL-V2 + SD-125EL-U2-FSKHD15 Data Radio is designed to meet the needs of a variety of wireless applications. They offer multiple functions, including baud rates ranging from 1200 to 9600, AC and/or DC audio coupling, and a programmable sub-audio squelch system (CTCSS & DCS) along with a two-tone squelch system. Additionally, the radios feature a signal level detect squelch system (RSSI) and GPS data handling to interface and control internal GPS receivers. The adjustable power output settings ensure optimal power usage. The SD-125E Series is designed with the most frequently requested mechanical footprint, featuring a DE9 male connector and a BNC antenna connection. The radios are equipped with LEDs that provide instant status updates. The die-cast aluminium cabinet/lid provides resistance to RF interference and exceptional environmental durability, making them suitable for use in extreme conditions.
