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 D. Kremp France 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. ~ RHF |
