Hi all,
I'm considering to upgrade my receiver ICOM R75 with narrow CW filters. My
main interest is NDB listening in the LW band.
There are 2 possiblities:
a) ICOM FL101 (CW narrow 9mHz IF, 250Hz) + ICOM FL53A (CW narrow 455kHz,
250Hz)
b) INRAD 121 (CW narrow 9010.6kHz, 250Hz) + INRAD 122 (CW narrow 455kHz,
250Hz)
Which combination is the better one in terms of quality and efficiency.
Price does'nt matter.
Any advice is welcome!
Thanks in advance

You may want to try using a Timewave DSP Filter. The DSP-59+ can be
had for about $150 US or less and the DSP-599zx for about $300 US. I
had the 599zx for a long time and wish I still had had it. It was a
very good filter.
