If you boys in ZL can't hear the German commercial monster Europe 1 on 183
kHz (2 megawatts erp) there doesn't seem much chance we'll hear you. All
the integration in the world isn't going to recover 63 dB (assuming it's a
reciprocal path of course). Working to VE7/W7 it is different - the
approximately north/south darkness path for you means daylight in our half
of the globe so Europe 1 shouldn't propagate around to VE7 and jam you
although it's only half as far away. It has to go over the Polar Cap so
add 20 db to the usual figures.
And vice-versa. Until you hear DBF39 you won't hear us on 136. And even
then we would have to make up about 37 dB. It might be a good idea if
somebody in ZL could organise an automated watch on DBF for the next six
months to see if anything is heard (seen?). Shouldn't be too hard to do
with Argo, Speclab, or similar.
