Re: My ammo can repeater build & My Homebrew Tandem CDM1250 Repeater Build
开云体育Dang Larry, ? This is Great! Pictures and arrows and exact settings for everything I had questions about. Perfect.. Thank you. I won’t be powering up the repeater until it warms up some as I need to install the antenna and run the coax up the tower. Don’t want to get into this until its pleasant outside, probably two, maybe three more weeks. I Will advise how it goes when it’s working but in the interim THANK YOU! Gregg – N4RGW / WQLY786 ? ?

It would be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience.” ― C.

The PDF schematic is attached and is very specific to my build and includes lead lengths in inches. The TX LED is not fully implemented because the polarity and levels do not match. I use the ignition sense to power up the radios, otherwise the radios will not power up after a power cycle. ? ? ? ?If you use the purchased cables you do have to figure out the pin mapping. I made my own cables because I wanted special wire and custom lengths. ?
