The Sounds Sweet comm speaker isn't a monitor per se but does a good job for me
when compared to the built in speakers I've used. Its big, about a cubic foot,
but plays plenty loud and clean, albeit somewhat mellow. About $180 delivered

I for one would really like to see a panadaptor for the K2. In an EC2 sized

Any others interested?

Does anyone know of a good way to remove frozen RF from an antenna? It
is now so thick on my wire that the new RF can no longer get through.
Let me clarify. The speaker frame can get distorted in shipping while not
installed in the radio. I've never had a repeat problem after correcting
the initial distortion.
To check for a twisted speaker, carefully move the cone in and out by hand.
Just push straight down on it
Is there a kit version of the artificial ground available? Even a

I've tried the N4PY windows s/w and like it. But that's the only one tried
so far. Are there others worth considering? Something more designed for the K2
