[Dxspider-support] Daily user disconnections

[Michael Walker]

Hi Mike

I noticed this a long time ago and the offending operator was me.  I
couldn't figure it out at first.

Now, I just use va3mw-1 and va3mw-2.  I've also told other stations to do
that and they can set unique filters for both.

As an example, I use va3mw-6 when I only want 6M spots.

A good reminder though.

73, Mike va3mw
