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
