Phil,
I don' t think it is necessary to have the same number of filters in
each receiver. My K3 main RX has 13khz, 6khz, 2.8khz, 500hz, and 200hz
filters. My subreciever has 13khz, 2.8khz and 500hz filters. This gives
me great flexibility with the subreciever and saved me lots of money,

Once, before my K3 lost its mind, if I keyed the VOX during the playing of

on REC will stop it. Rather unhandy for contest operating.

If I were to buy the K3 subreceiver I understand that performance is best if
