The frequency is getting away a bit from 136 but twice in the last week,
around 0400-0600Z, I decoded the Cape Race, NFLD, differential GPS
transmitter on 315 kHz (3802 kms). I leave the DGPS receiver running on
the channel overnight and record data every 30 seconds so I don't have to
stay up all night. Another DGPS station, in Iceland (Reykjanes, 292.5 kHz,
1916 kms) comes in all night from 2200-0800. These are only 10W erp
stations using MSK 100 Bd.
Last year, in December, I several times received and decoded successfully
the US Coastguard NAVTEX station at Miami, Florida (7110 kms). It operates
on 518 kHz so perhaps it doesn't count, but it's only a 50w station.
Incidentally, the Decca Green stations of the Bothnian Gulf chains (roughly
1600 kms) are trackable on my Decca receiver here most of the day as well
as all night. They're on 127.5 kHz or so and are about 40w erp.
It would be excellent if we could be advised of when CFH will be on the air
and even better if it could radiate standard DGPS data so I could use my
automatic monitor!!
