Topband: 600 m operation

As many of you are aware, a group of us has begun experimental operation on 
600 m (505-510) kHz.  I am on the air at 506 kHz operating in the beacon 
mode.  The message is:


After each transmission there is a 40 second pause and then the message 

The planned operating times will be 0100Z to 0430Z every day possible.  No 
doubt there will be some exceptions but I will do my best to be regular for 
the next 3-4 weeks.

I have up a 130' vertical with a 300' top loading wire and am running the 
maximum allowed power so I should be audible over much of the western USA.

I would appreciate any signal reports.  Please send them to me off this 
reflector at: rudys at  This will be a very interesting experiment 
and we all hope it  results in a new MF band for hams.  That of course is 
very much for the future. Right now we need to see what we can accomplish 
with this experimental license.

Thanks everyone and 73,

Rudy N6LF
