Re: [TenTec] Filter question

Vern-

I saw no reponse on the reflector from someonw more knowledgable, so 
maybe I can help

The Ten Tec filter for digital modes is the 216. It has a passband that 
aligns over the mark and space signals in RTTY. Ten Tec no longer sells 
it, so you'll have to find an individual with one for sale. They show up 
occasionally on the reflector--I just bought one that way.

I don't have a 217, but it has a different center frequency that places 
the passband over a CW tone. You won't be able to hear a RTTY signal 
with it inserted in the audio train. At least that is true with the 
INRAD 400 hz filter I use instead of the TT 217.

You can use the Ten Tec 285 filter with RTTY, but you have to adjust the 
Omni Passband Tuning control to the 3 o'clock position to hear RTTY. 
Then you have to readjust it when you go back to CW.
