The repeater works fine into a dummy load,as I stated. Its also better if I shift the rx or tx away from that 600khz split,starts to clear up if I put the tx on 147.28 or .26. The returned interference also carries my CG tones which holds the repeater open. I have changed the tx CG to a different tone so it doesnt loop. I have tried my stand-by antenna with the same results,I dont think its the antenna. I also hear the same buzzy carriers ant different frequencies all over the 2m band.I am going to attempt to RDF these carriers this weekend....
