James,
The situation on 40 Metres has actually improved dramatically and the
broadcasters HF Co-ordination Committee has carried out an incredibly
hard task in making sure the majority of their members have moved at the
scheduled time. The result is that there should be no European
broadcasters and few American continental to be heard.
The problem lies with those nations that are either not members of the
ITU and would not respond to official complaints anyway, or those that
have not yet got around to moving despite the 6 years notice given.
Those of us that remember the 60's and 70s will remember that in the
segment 7000 - 7100 kHz there was even less room to operate than there
was in recent years. 7050 had Radio Cairo operating almost 24/7, Radio
Tirana was on 7060, Iran on 7075 etc etc. so it was time, diplomacy and
patience that slowly wore them down over the years.
It would be naive to think that all broadcasters would vacate on 29th
March but the IARU Monitoring System has been asked to keep a watching
brief on the new segment and to report on the ongoing situation.
Perhaps you would like to participate in this exercise?
Patience is a virtue. In the UK we were fortunate in being allowed
early access to the extended band as early as 2004 . Others have not
been so fortunate and that not all administrations have yet enabled
amateur usage of the expanded segment and that includes our near
neighbour France.
By the way, most of those still in the band with the exception of Iran
and China are located in places like Somalia, Eritria, Guinea, Ethiopia
and Sudan who say they cannot afford to change frequency at the
moment. Iran says that their domestic listeners don't have receivers
that cover above 7.2 or 7.3 !!
