[TenTec] Orion 500hz CW filter

[Joseph Trombino Jr]

Believe the switch to the Inrad 600hz 4 pole filter instead of the stock Ten 
Tec 500hz CW filter was made because of increased IMD when using the Ten Tec 
filter.

Believe an amp was turned on when the 500hz Ten Tec filter was selected to 
make up for the loss of the filter but this amp caused the increased IMD.

The Inrad 762 filter is installed in the spot taken up by the 1khz filter 
and I think the stock Ten Tec 500hz filter is pulled altogether.

I wonder if it is possible to keep the 1khz filter as is and install the 
Inrad filter in the place of the 500hz filter and also somehow disable the 
amp that follows this filter.

This would keep the 1khz filter in its original place.

Can the amp following the 500hz Ten Tec filter be disabled easily (or at 
all)????

Just some rambling thoughts....I have a 762 on the way and was wondering how 
to keep the 1khz filter in its original place but also make use of the 762.
