Hi Pete
Its quite obvious that the allocation
is quite able to support normal
armature activity , and why not ? its no longer a
experimental allocation , its just the same as
10 or top band , un expected results today though
! ssb sounds odd , may be as the
path is stable , sstv ? must be a
narrow mode , and the 'new' digital voice is
2KHz , but that requires a linear Tx
path
As for the band edge
I'm straining to find a
engineering reason , that wspr and
qrss has decided to run mid band ? Im sure users
had a reasonable discussion at the introduction of
the band , to place the modes at the edges
, with live cw a the lower portion ? its
well know that these long carrier
modes cause disruption to other band users
and are well placed at the band edges
, 'vanity beacons' is a term I have seen
noted in referral, as occupancy increases , by users not
linked or even aware of discussions
taking place on these groups , i'm sure there will
be problems leading to the introduction
of band plan's , for some the plans
form part of the licence conditions ..
Is Opera a vanity system ? , actually no, it
compliments ros- data mode in that the ave
s/n readings can be used to determine if
a path will support the data mode ,
each having the same averaging s/n
reading taken along the time line ,

Hi all
One SSB channel at the high edge of the band only used during
daylight hours no DXing!

Quite intriguing propagation on this 'new'
band
From some unexpected early 600 mile
+ Opera decodes last night , to
several wspr TA decodes , [G8's
again ..] to today's
test with Gary using USB-SSB voice ,
Where as at 1300z we
had 5/9 signals each way as expected
over 25 miles , GI3PDN Ray , called on CW
, to give a report of 5/9 across the
Irish Sea , some 100 miles for
our two signals , his CW also in the 5/9/9
region, one wonders how far inland the
signals travelled ?
After a short 3 way qso, we closed the
test round 1330z , may not of been
quite as sociable after dark , but
with a small Ae , 40 x 70 ft iv L
and 35 ft Top load vert , 50
watts pep , results defiantly superior
to say 160 mtrs using the same Ae's
