The band from 7100 to 7200 should be clear of broadcast stations and finally
allocated worldwide as a ham band. Hopefully this will clear the bottom of
the band for CW and several noticed that there was little SSB in the ARRL Dx
below 7040.
Two questions remain:
1. Will there still be conflict between SSB Dx and Digital? For one
thing, US possessions (KP4, KH6 et al have SSB rights between 7075 and 7100.
If you listen in the early evening VE's are all over the 7040 to 7100 with
SSB. There is a group that come up on 7063 each day regardless of who is on
the frequency. I missed XU because of this and I only need 5 entities on 40
including XU. This was about 2330Z and we get a fairly decent long path
opening
in late November through Christmas. On a digital weekend they fill the
band between 7040 and 7100 and on SSB Dx weelends SSB covers the same area.
I was expecting the DX to try splits from 7100 to 7125 where USA cannot
operate. Most say this got off to a slow start. Loud multi KW Europeans
can hold a frequency between 7125 and 7200. This is not new as many have
been working simplex for a couple of years.
2. The second issue is will the band be clear of broadcast. Sunday night
there was BC stations on 7105, 7125, 7135 and 7155. This is down quite a
bit from say one year ago when the BC stations made split Dx a nightmare.
Lets hope they go away as that middle east station on 7070 finally did a
couple of years ago.
Remember we still have 7200 to 7300 but the BC QRM is still bad there.
