Dail,

You mean you did not get Bird 43 flue by opening it up and letting the air out 
into your enviorment.  This gives me confidence, hi.

Yep at +/-5% of full scale the Bird is not very accurate.  I think it is good 
for what we use it for.  I also think because it is built strong it is popular 
although it don't handle being dropped from 1000 ft tower very well.  Working 
to 1 Ghz when 1 G was magic also helped.  Also the higher power capability.

73, ron, n9ee/r

>Great info Gary , I have a similar Question My Repeater puts out 100Watts  So
