Thanks for replies on 8 pole xtals offset = 0. Now, it seems I have a packing mistake. I have the KAT3, but only one SO239 was shipped. I installed it at ANT1. In the KAT3 packet, I find the KAT3 circuit board, the install instructions, and a packet of hardware labled "hardware for KPA3". It appears it was packed instead of the additional SO239. Ken K5WK
