[TenTec] guide to adjusting Orion receiver; filters and performance

[Ulrich Hilsinger]

Hello,

at least in some cases I can confirm Sinisa's observations. A 
sufficiently high AGC threshold (probably in combination with some hang 
time) improved readability at least on some signals, f.ex. on 30m, which 
is a horribly noisy band at my QTH. Tested it only a few times this 
evening, got my ORION today....

73,
