Hi ALl,
Originally this section of the 10 metre bandplan had a downlinks only
restriction but this has now been removed in IARU Bandplans. From memory,
Region 1 removed it at their Sun City Conference in 2011, Region 2 at their
Conference in Cancun in 2012 but I don't think it was ever shown in any
Region 3 documentation.
The original reason for it being there is unclear. It may have a been a fear
of possible CB interference or it may have been because AO7 only used 29MHz
for a downlink.
There often difference between the ITU allocations for the amateur satellite
service and frequencies shown in bandplans.
For instance the complete 10 metre band is allocated by the ITU for amateur
satellite operations but our IARU bandplans show just 29.300 29.510MHz.
Also, on 2 metres, the ITU allocation is 144-146MHz but by IARU agreement we
only use 145.800-146.00MHz plus the new section at 144.0025 -145.025MHz
which has already been agreed by IARU Regions 2 and 3 and will hopefully
also be agreed by Region 1 at their Conference in Bulgaria in three weeks
time!
Of course there are occasions when member societies have local variations of
these regional bandplans but I would hope, in this case, it is simply an
updating issue.

Hi Trevor.
I went off and looked at the UK allocations when I read that. Seems to be
up or down and not limited to 29.3 either.
But, I did notice that 10.475 GHz to 10.500 GHz is allocated to the amateur
satellite service, but not to amateurs in general. i.e. no terrestrial
use. - That's a first !! We've got our own piece of spectrum.

Hi David,
I'd use the words "a disaster" rather than "a first".
The Amateur Service in the UK lost 10.475-10.500 GHz in 2006. While it is
notionally still allocated to the Amateur Satellite Service the high-powered
commercial stations that now occupy the segment render it unusable.
Below some related links regarding the loss of 10.475-10.500 GHz.

Oh, I forgot to mention HO-68 has a great CW beacon at 435.790. Listening to
it right now. It's also in a great 1200km orbit, so long passes and slower

A few suggestions based on my experience.
Don't use HRD for sats, especially to tune. SatPC32 is far superior for
satellite tracking, and while some stubbornly stick to HRD, those that move
to SatPC32 rarely go back. You don't have to register SatPC32 to begin using
it.
Forget auto tuning to start with. Run some pass predictions and double check
them with the AMSAT page. and listen, tuning around a bit. Point the
antennas at the TCA heading (time of closest approach) and listen there for
the entire pass to begin with. This will compensate for any clock, kep, or
frequency inaccuracies. During the week and when illuminated, AO-73 has a
booming BPSK beacon. FO-29 is weaker, but always there. Start with those two
and see if these steps lead to any success.

There are even more problems with the ARRL's "band plan" for 10-meters. The
frequency of 29.300 MHz is widely used, especially in Asia, for 10-meter FM
operation and, when 10-meters is "open", it is easy to work, from the United
States, Japanese stations on 29.300 MHz. Then, 29.510 MHz is within the
29.500 MHz to 29.700 MHz segment in which FM repeater operation is allowed
for stations within the jurisdiction of the FCC.
Also, many operators are not aware that FM/PM operation is allowed anywhere
that phone operation is allowed EXCEPT for the 5-channels in the 60-meter
band. The only restriction is that, below 29.000 MHz, the modulation index
cannot exceed 1. Modulation index is defined as the absolute number of the
deviation divided by the maximum frequency of modulation. This means that,
below 29.000 MHz, the deviation is generally limited to +/- 3 kHz. Most
"modern" transceivers, that have FM operation available, have a "narrow" FM
position which limits the deviation to +/- 2.5 kHz. With the usual +/- 5
kHz deviation, and with the 3000 Hz maximum modulation frequency in most
equipment these days, the modulation index is 1.66667 which means that such
modulation has to remain above 29.000 MHz. Conversely, a deviation of +/-
2.5 kHz results in a modulation index of 0.83333 which does meet the
requirement of the modulation index being less than 1.
However, in the 28.300 MHz to 28.500 MHz segment, in which Novice Class and
Technician Class phone operation is allowed, those classes can only use SSB
for phone operation, as well as CW, as outlined in 47 CFR Part 97. However,
higher class licensees, General Class, Advanced Class, and Amateur Extra
Class, operators can also use AM, FM, PM, ACSB, as well as SSB in that same
segment.

I am glad we have moving birds and not stationary ones.? Somehow someone
would repeat this on the birds today if it were easy.
The point being, gentlemen and gentlewomen, should coordinate and help
each other, not tie up repeaters and ISP time fussing about human nature
that is not going to change with out conscious effort.

Friends,
Kent Britain, WA5VJB (a.k.a. Mr. Cheap Yagi) is looking to borrow a
cubesat frame for some antenna testing. If you have a cubesat frame that he
could borrow, please email him directly at wa5vjb at flash dot net.

Just a reminder that the award period for the 73 on 73 Award begins at
0000Z on September 1st, so begin keeping track of the unique callsigns that
you work on AO-73. When you reach 73 unique callsigns in your log, email me
at n8hm@xxxx.xxx with a list of calls, date, and time worked (in UTC) and
your mailing address. I hope to have a website up soon with an example of
what the award will look like.
Some tips for working AO-73:
-Keep in mind the frequency drift on the transponder. The offset needed on
your transmit frequency is usually from +10 kHz to +16 kHz. This can vary
throughout the pass, requiring frequency adjustments if using computer
control. Many find manually tuning the uplink to maintain a constant
downlink to work better than computer control.
-I usually start a pass by trying to find myself come into the top
edge of the passband (145.970 MHz). To do this, I usually start
transmitting around 435.135 MHz and tuning up slowly until I can hear
myself enter the passband. Then I can move around the transponder
easily. Remember to tune your uplink to maintain an constant downlink
frequency (the opposite of FO-29).
-Keep power output down. The transponder has a very sensitive receiver
and a very active AGC circuit. Excessive uplink power will not make
your signal louder - it will only reduce that available for others on
the transponder. With a clear view of the horizon, 5 watts to an Arrow
or Elk is plenty for horizon to horizon coverage. Very slightly more
might be necessary if you are beaming through trees or other
obstructions, but try to keep power to 25-40 watts ERP.
Good luck! Who will claim the 73 on 73 Award #1?

Hi!
One of the unique calls you may be able to work on AO-73 is
W1AW/7. I plan on being on AO-73 tonight as W1AW/7 at 0359
& 0534 UTC, and at least the 0420 UTC pass on Monday evening
(Tuesday morning, on the UTC clock), while I still have the
use of that call. After Monday evening, I'll add my own
call to the mix that you can work toward the 73 on 73 award.
73!
