I'm in the middle of transitioning my megaspot (STM32DVM + Tait TM8105 VHF transceiver) to a homebrew repeater setup using two UHF Motorola CDM's... a 40W CDM750 for the TX radio, and a 25W CDM1550 for RX. For testing purposes, I'm setting the power as low as possible, and plan to put a dummy load on the duplexer output. Will this still allow me to work the repeater from on my suburban lot, or will the dummy load soak up everything? I don't want to splatter RF all over the neighborhood while I'm testing, but I do want to be able to interact with it via HT from the garage or similar.
The previous setup used a HT antenna (Signal Stick on a BNC 90º connector), but that worked OK because the Tait was able to be set for a TX output of 1W. The CDM's seem to be a bit less configurable in some respects.
