Install the Inrad filter in the 1000KHz slot. Remove the 500 and 250KHz
filters. With the 1800KHz and the 600KHz (Inrad) along with the
variable bandwidth controls, you will have all the flexibility you need.

Rich:
Thanks much for the response. Would I be better off getting the Inrad
filter, installing it in the 1000Kz filter slot, removing the optional
500 KHz Ten-Tec Filter, and keeping the optional 250 KHz filter, or some
combination of the above?
Any suggestions or comments would be greatly appreciated.
Thanks,
Scott K4VWK
