I was messing around with my friends RX-65 (V 6.2, M4 antenna) and I turned my V1 (K and KA on, POP off) on, and surprising to me, the RX 65 leaked K from about 4 feet away. When the RX-65 was right next to the V1, the V1 was at full strength. I thought only the lower end detectors leaked enough to be picked up by other detectors? Why did it leak on K band and not on KA? A J alert is for KA only, correct?
