Dear Ulderico and the group,
>I would like to install an optional narrow filter in my TS450SAT, a
>250Hz or 500Hz at 455 KHz or 8.83 MHz IF, normally for CW, and then use
>it on USB with PSK31. Does anybody know if this works, or maybe the
>narrow CW filters cannot be selected when in SSB modes?
Yes, it does. The TS450SAT is excellent in this respect. It lets you use any
filter in any mode.
When you are using a narrow CW filter, you will find it convenient to set the
PSK31 CenterFrequency to a value other than 1000 Hz in order to have the desired
signals in the center of the filter response.

>Is there a real advantage using these narrow filters, compared to the
>2.4k at 455KHz IF and the 1.8k at 8.83?
Yes, the adjacent channel strong signals can overload the AGC, but with a sharp
filter in the IF, this effect is reduced.
Please note that if you install the 250 Hz CW filter, that it will be displayed
in the dial as 500 Hz, but it really is 250 Hz.

Thank you all for your replies and suggestions about the narrow filters
on TS450. I will buy the filters as soon as I leave the hospital
(nothing serious... our first baby was born today, her name is Federica
and maybe she will become a ham sometime in the future, following her
parents' steps).
Next week I will probably be able to test drive the filters. Hope to
meet you on air.
Ciao.

Subject: [psk31] Who wants to try 3580 tonite?
Hi all,
Like WB4YDY, I'm trying to scare up some 80 mtr
PSK activity.
Right now its 0139z and I'll be up on 3580 +/- 1kc
looking for some contacts.
I'll be on freq till about 0230z, so c'mon down (up)?)
and make some noise, use it or lose it.....
