Hi Roelof,
Thats very interesting. I see the 2 navtex towers at the Coast Guard
site frequently. The base insulator for my tower came from a tower
that was used for CW and later navtex before it was decommissioned.
CW again tonight on 477.7 kHz.

Hello Joe,
Contrary to the Subject, propagation was worse last night.
Yes, the beauty of LF propagation is that not a single night is the
same as the previous one. It should be rather boring if it was.
Fading is another interesting matter. Due to the shared channel and
time slot policy of the NAVTEX service on 490 and 518 kHz, it is
difficult to receive Robin Hood Bay (St John's) from Newfoundland on
518 kHz. It has a shared 10 minute timeslot with Portpatrick in
Scotland and NAVTEX Malta. Portpatrick is 700 km away and most times
uses the full ten minutes. Yet, on many occasions Robin Hood Bay has
been received here faultless as Portpatrick is at times completely
gone due to heavy fading.
