[amsat-bb] Re: Use of ICOM 910 for AO-51 L-Band BBS Uplink?

[Dale Hershberger]

Hi Jim,
   I have the IC910H with the L band module.  I have used when AO51 is 
in L/U mode.
I am using LMR400 for feed and I have a DEMI Circular polarized 12 turn 
helix antenna.
When I am on AO51 I can not get to low to my horizon.  I know it works I 
have been able
to work Washington and California  from south central Alaska with it.  
My plans are to get
one of the KJ6KO amps and a power supply for the amp.  I am pleased to 
have it working barefoot.
 I may have 6 watts at the antenna.
