Strange behavior on 80M split operation. K3/KRX3 interfaces with BiggIR vertical through LP-Bridge on 80. Running simplex on 3503 all is ok. Running split on 80: RX 3503; TX 3505, the BiggIR heads for the hills 35Mhz!!! Somehow the band data from VFO B is "squirrely". As soon as I go back to TX on VFO A, all is ok again. Jim k7eg
