Greetings all, I’m running a Motorola RKR1225 40 watt repeater that should be transmitting 30+ watts after duplexer but I’ve only ever realized 27.5 watts however, that’s not the main issue. When the unit first starts transmitting my test meters (tried three different ones) all show 27.5 watts. But, the longer the repeater remains transmitting, the lower the transmit power goes. It’s a slow but steady drop from 27.5 watts down to 23 watts. I’ve double checked all of my connections and my SWR meters all register 1.00 (using a DM-408B and temporarily using a 35’ run of LMR400 since I’m hoping to relocate the system to a local hospital for better range and saturation and decided to save my heliax cable for the new location. I just can’t figure out why the constant drop in tx output power. As always, I appreciate any and all suggestions and look forward to the replies. John WRDM373
