[AK-VHF] RSVP: 6 Meter Antenna Test on Tuesday Evening

Hello group,

Good points about band openings. What I'm envisioning with this antenna 
is to just get a start on the band, and use it for the digital net 
coming soon. Later on I'll probably be setting up something more 
substantial for working band openings. I need to come up with a design 
that is reasonably compact though. Fun project for another day!

I'm going to go on-air tonight at about 8 PM local time and do some 
testing. I'll be operating on 50.125 USB. I'll start out with about 20 
watts and then adjust up or down as needed.

Thanks everyone,

Brandon
