WHEN I realised the capabilities of such a small device – the Arduino Dué, I began to believe that with my experience of repeater building with analogue systems with the Raspberry PI, I could easily formulate a plan for a digital repeater in the same way. Looking for MOTOROLA Two Way Radio Repeater, VHF, 136 - 174 MHz (460X27)? Grainger's got your back. Repeaters have a time out function that will shut down the transmitter if the repeater is held on for a preset length of time (normally three or four minutes). September 2018. 5 & 1W • Power supply 8-13V DC *only Rx, limited Tx power on frequencies outside covered band . Set the power levels carefully!! • If using cross banding into a busy VHF repeater, the UHF transmitter in the cross band repeater will be active any time the VHF repeater is active. kunne være spændende at lave en styring til en repeater med en PIC, men det blev aldrig til noget. That means, you can operate on HF and listen or transmit at the same time on VHF or UHF, all through the same coax cable. Getting your Ham license is easy too! All that is Glad You Asked, I have implemented this…. 880 & 442.

This setup 2m VHF Duplexer for portable repeater « 1 2 eHam > eHam Forums > Repeaters. Just for experimentation and local repeater access as these modules are only 1W maybe even do APRS RT97 Portable Repeater - Retevis Multi working power selection, working with the matching power adapter, and also can work under DC12V~24V power or car power. 800MHZ + 5 Tone 88. I spent Saturday, 2/9/19 reconfiguring, reprogramming, and realigning this machine for Lee (KE4COL) and he transported it to the repeater site and fired it up on Sunday, 2/10/19.
