Hi Bill, This is incorrect. The 2.7 kHz 5-pole can only be swapped for a 2.8 kHz or possibly the 2.1 kHz 8 pole filters. We require at least one SSB b/w filter in each K3 as it ships since we must also transmit through the filter for SSB and data modes. Transmitting through the 2.1 kHz filter will limit your tx bandwidth to that value. ( I'm not aware of many choosing the 2.1 as their only SSB filter - I may drop that as a swap option to make sure no overly narrow TX K3s get out there and confuse the market.) Is 2.1kHz really overly narrow for SSB transmit? I know people are talking about 1.8kHz filters for RX, and it seems useless to transmit energy that's not going to be used. It's certainly wide enough for data modes. In fact, it might be useful to be able to TX through the 400Hz filter in some of those modes. 73, doug _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
