[TenTec] On Inrad filters

[Jim Reid]

> My TT tends to loose a lot  of sensitivity with 500 filter. 

Hi Alan,

Gosh no,  but I am using two Inrad 400 Hz for Cw.  My filter
line up  is:

9 mHz IF strip:

IRD 754,  2.8 kHz
IRD 756, 2.4 kHz
IRD 753, 400 Hz

And on the pass band,  6 mHz board:

IRD 755, 2.8 kHz
IRD 757, 2.4 kHz
TT 288,   1.8 kHz
IRD 700, 400 Hz

I often use only one of the IRD 400 Hz CW filters, and
not too often use other than the IRD 2.8's for SSB; only
go to some narrower set up during SSB if the QRM is
really close.  I only do DX "picking"  during contests,
don't contest, as such,  at all,  SSB nor CW.

In fact,  my Omni is now pretty much set up for PSK31
QSO's,  with which I am using Hamscope,  which is
great for that mode.  Of course,  use the 2.8's for
monitoring the range of PSK activity.

Certainly,  no loss of signal sensitivity,  Alan.

73,  Jim,  KH7M
