Hi Group, Since this club has a back up rpt. Take the rpt out of site and test off site test rx selectivity and sensvity, tx power out deviation. usally test the rpt into a dummy load(i use a cantenna)for a week or so. key the rpt up for 24 hours with the bird watmeter inline. see if wattage changes. the mark 4 cr rpt is usally stable for the tx. the rx is deaf. Jsut curious has your club just hooked up a mobile radio on the antenna system with the bird inline and see what is there. i am guessing the kendecom is seeing rf and with a hospital site not much antenna site maintance happens and ground issues develop. like the hospitals 5.5 -8 khz wide 350 watt paging system that has a issue but not noticed.A few things i have ran into with hospital sites and lower quality rpts.
