Hi all,
I'm considering to upgrade my receiver ICOM R75 with CW narrow *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

DK,

Why not the this Combo ?
FL-100 CW/RTTY Narrow 500 Hz Filter 9 MHz IF
FL- 52A CW/RTTY Narrow 500 Hz Filter 455 kHz IF
Narrow enough for NDBs and better Audio Quality.
