Hi Doug,
Filter bandwidth is stored per-mode. At present, all data sub-modes
share the same bandwidth. I'll look at what would be required to split
them out.
Meanwhile, you could use the user-programmable NORM settings, 1 and 2,
to switch between two often-used bandwidths in DATA modes. See

I too would place lightning damage into the "Acts of Nature" category

failures and failure to perform to specification, which is different IMHO.

I was hunting around for some action today on the 20 meter band with CW. Did

it is a real key click or not or maybe just some artifact of the sidetone

Some companies bring out new transceiver models every year or two. Our
philosophy is different. We'll continue improving the K3, protecting
your investment. Similarly, the P3 and KPA500 will extend the

That's not as much a dig as it might sound. A common occurrence after

on their own inconvenient schedule.
