We have had the works today but not tonight thing as well as 1 day its perfect and then nothing for 5 min then ok again. we dont sell URC anymore because of that, wellat least not with a RF unit. testing with IR they were all 100%, added the RF and days were lost trying to get it to work, one job we removed the RF and installed IR repeater system and it actually worked better than the RF.

We are RTI as well and have had no problems with RF, I did a job last week and installed the antenna in a conjested area with Neon, Metal conduit, metal duct work, metal ceiling and lots of AC...above a Vantage Panel and the RTI had no problems with RF

Still get calls fron clients with URC MX3000/MRF combos saying it responds poorly, we are swapping out one next week with a T3/RP6 setup and junking the MX3000
