on topband with the new roofing filter from Inrad for the FT1000(D) series.
I decided to upgrade my old FT1000 (see also the w8ji site) and keep it for
more years. Also i am not using the Ft1000 250 hz
filters because of to much signal loss.. Change into 400hz filters
worthwhile ?Bet,
i recently installed the Inrad roofing filter in my FT1000D. If you are
looking for a magic bullet, this is not it. However, it does what is is
supposed to do. It provides a noticeable improvement in topband CW operation
by virtue of helping to minimize the effect nearby strong signals. This is
most noticeable in the operation of the noise blanker. Casual operators might
not notice the difference, but it is there and if you are after the last
possible bit of improvement, it's worth the money.
The kit is well done with good instructions and an easy installation.
BTW, if I didn't have my 250 Hz filter, I'd have to give up low band CW. If
yours causes "too much signal loss" I'd say the filter has gone bad and should
be replaced. No signal loss in mine.
