[TenTec] Orion Filters

[Scott Harwood]

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
