[TenTec] Older Ten Tecs and Roofing filters

[Paul Gates, KD3JF]

I believe you are right. I understand the important thing is to get the filter in that first IF. I have had a lot of Ten Tec rigs. A 540, 2-544's, <Triton IV> 509 Argonaut, Delta, Argosy. The thing I liked above everything else was the receiver Audio! It was as good as any tube audio... My granddaughter has a Drake TR-3 and the receive audio is so pleasant to the ears.That is my 2cents worth.

  In looking over the reviews and other on-line sources
for rigs, it looks like some of the older Ten Tecs
(Omnis, Corsairs I and II, but not the Paragons) use a
low first IF (9 mhz or so) with crystal filters there,
as well as in the 2nd IF. So the filters in the first
IF would be a roofing filter, correct? Just like what
Icom and Yaesu are now discovering, if I understand
the roofing filter concept. This should make the close
in spacing on the Corsair II and these other rigs very
good, correct?
