[TenTec] Mystery Filter

[Mark Hinkel]

Hi Stuart,

Yes I've seen some of the new software for doing PSK-31, Slow Scan,
RTTY, and others.  And yes, I've seen the wide "spectrum analyzer" at
the bottom of the monitor screen.  All very nice...   I want a Rig
Blaster...

And now that you mention it, I guess it does take a pretty wide filter
to "look" at all that spectrum.

But tell me this;  once you've set the software to receive the
particular DX signal, and discover the typical busy band (one signal on
top of the other), aren't the narrow IF filters helpful to "hone in" on
it??  Or is the software controlled "DSP" all that's necessary??

Thanks.

PS: I already have a JPS / NIR-10.  It also is very nice!!  It'll turn
any old general coverage receiver into a much newer sounding rig.  (all
on just the audio output)  But thus far, I haven't been able to make it
do anything the standard IF filters on the Corsair II won't do.  I know
you already know this...   but I'll say it again;  the Ten Tec filters
are top notch...   superior to the "run of the mill" stuff out there.
