#6m transatlantic propagation

Posted: 10 Jun 2022 03:47 AM PDT https://pe4bas.blogspot.com/2022/06/6m-transatlantic-propagation.html





There was some reasonable propagation to USA/Canada yesterday evening. My signal was received by many but only worked a few. The problem is the huge amount of european stations on 50.313MHz FT8. There is an alternative DX frequency 50.323MHz especially ofr DX but somehow it takes considerable
time before DX moves there.
I also worked a new band DXCC which was D4L from Cape Verde. The contact
was made on CW, very unusual these days :-). Early in the evening D4L had a real 599 signal over here. And since everyone is on FT8 you now have a
chance to work DX with CW/SSB if you listen carefully.

#4m strong IORT FM stations

From https://en.wikipedia.org/wiki/FM_broadcast_band
The OIRT FM broadcast band covers 65.9 to 74 MHz. It was used in the Soviet Union and most of the other Warsaw Pact member countries of the
International Radio and Television Organisation in Eastern Europe (OIRT),
with the exception of East Germany, which always used the 87.5 to 100
(later 104) MHz broadcast band—in line with Western Europe.
Countries which still use the OIRT band are Russia (including Kaliningrad), Belarus, Moldova, Ukraine, Lithuania and Turkmenistan.
The 4-meter band (70–70.5 MHz) amateur radio allocation used in many
European countries is entirely within the OIRT FM band. Operators on this
band and the 6-meter band (50–54 MHz) use the presence of broadcast
stations as an indication that there is an "opening" into Eastern Europe or Russia. This can be a mixed blessing because the 4 meter amateur allocation
is only 0.5 MHz or less, and a single broadcast station causes considerable interference to a large part of the band.
