These experiencies give me more hope. Several times I tried to listen to 136
kHz on my IC-751A and long wire (80 meters), heard nothing but noise of various
kind. One suggestion. Few years ago I came across a schematic diagram of
receiver for NAVTEX (I was R/O and /mm that time). Directly on input of rx
there was a crystal filter on 518 kHz, where NAVTEX transmits. Would it not be
excellent solution to make crystal SSB-wide filter centered on 136.7 kHz and
put it between ant and rx? I know there is only one problem - where to get
crystals around 136 and 137 kHz..., hi
