[TenTec] Tuner in Orion

["Bob KIrkland" <w5pvr@gower.net>]

I have followed these tuner postings with interest and am surprised that no one 
has
considered the tuner from the receiver standpoint. There is little to no 
selectivity for
the transistorized rf amplifier and it is subject to being driven into 
superiors output by
an adjacent strong signal. This is worse on ssb than cw, and that is why you 
have an attn
button to reduce the sensitivity. Try tuning in a crowded band with the tuner 
off, and off
frequency then turn it on, works much better.
