I was looking through my ham radio bookshelves (yes, plural!) a few weeks
ago, and I had nearly forgotten that I had this book...so I've been
re-reading it. (No, I'm not interested in selling it.... <grin>)
The history alone - details about the birds up to and including AO-13 -
makes for fascinating reading, never mind the technical details for
orbital considerations, tracking, and building satellites. Remember that
this when AO-13 was only 2 years old, AO-7 hadn't been heard from in a few
years, and FM birds were only a twinkle in some engineer's eye.
If you can find this book, I highly recommend that you borrow/buy it -
quite interesting to read what was going on in the satellite world 28 years
ago! (I bought it in late 92/early 93 to read on the plane trip to VP2M
for an AO-13 DXpedition.)

Hi to the list,
is there anybody that owns a Kenwood TS-2000 that has used
with the Digital FM satellites like the old KO-23 KO-25 UO-22 etc?
If yes how has do it as I have noticed that if I put into Satellite mode,
First I cannot put it in Packet mode and second the SUB RX becomes muted,
But if I set the SUB, as CW or LSB or USB, the SUB becomes loud again.
If I am not into Sat mode, I can receive in any mode either on SUB or MAIN.
Is it normal or the radio has a problem?
Please How to work the Digital Satellite?
Any help will be really appreciated.

I have both first and second additions. Martin is an excellent author
and still pops up here in the BB sometimes.

This Friday and Saturday (5/4 and 5/5 EDT) I'll be taking part in the New
England Tech Trek at NEAR-Fest. It?s a youth outreach STEM activity. This
takes place at the Deerfield Fairgrounds in New Hampshire, USA. I believe
the grid is FN43; we will be using special event call sign N1T.
I'll try to post a set of passes that we will be working with a GOTA (Get
On The Air) satellite station. Remember there will be a bunch of
inexperienced kids (and me!) so I hope you will all be nice to us :-), but
also please respond and ragchew when appropriate. I'll do my best to
record contacts and acknowledge QSLs, but this is my first time at this
sort of event, so we'll see what happens.
More later.

Hi!
I will have an AMSAT table at the Cochise Amateur Radio Association's annual
hamfest on Saturday morning, 5 May 2018. The hamfest will be held at the
CARA's "Green Acres" field, along Moson Road south of AZ-90 in Sierra Vista,
Arizona. More information about the hamfest is available in the flyer at:
http://www.k7rdg.org/2-Events/2018_CARA_Hamfest.pdf
During the morning, I will have on-air demonstrations of satellite operating
from the hamfest site. I will use my own call sign WD9EWK, and please call
WD9EWK to be part of the demonstrations. All QSOs will be uploaded to
Logbook
of the World sometime after the hamfest. The hamfest site is in DM41.
I will post updates from the hamfest on my @?????? Twitter account. If you
do
not use Twitter, you can still see these updates in a web browser without a
Twitter account:
http://twitter.com/WD9EWK
I will squawk WD9EWK-9 to the APRS network as I drive to and from the
hamfest,
and around southeastern Arizona. This should be visible on various web
sites,
including:
http://aprs.fi/WD9EWK-9
Thanks, and 73!

I posted a list of passes on the AMSAT Facebook pate for Friday that are
visible from FN43. I expect to be working most, if not all passes on
Friday between about 1030 EDT (1430Z) to about 1600EDT (2000Z). Saturday,
the times are different and I'll post those when I figure it out :-)

Vincenzo,
How many satellites at a time do you want to look at? SATpc32 can show up
to twelve at a time and that is more than I can visually keep track of.

I don't want to be an alarmist, but we need the Hams with the proper
knowledge to get involved in this disturbing news.
The National Electric Code now requires electronics on every module of a
solar array communicating via signalling on the DC power lines to assure
EACH pair of panels can shut down independently. This is to make all
possible faults never allow more than 80 volts anywhere in the system.
This is effective 1 Jan 2019
This is the nail in the coffin of simple DC series string arrays which are
the quietest systems and almost demands microinverters or optimizers on
every panel. Refer to the QST article a few years ago about how disastrous
optimizers are to RFI and HF operations with modules all over the roof..
Here is the Solar news:
https://solarbuildermag.com/bos/nec-2017-module-level-solar-system-shutdown/
Also, what is going to happen to an array that has signaling all over it in
the near field of HF?
Although you can avoid it by going solar before then, you may have problems
when your neighbors go later.
I hate to be an alarmist but we all know what happens when ham radio and
commercial systems are incompatible and even though Ham radio might be in
the right, we are only 1 in 600 and no one is going to side with us.
We took on broadband over power and squelched that dumb idea, but now this
has the potential for equal demise of Ham radio. It should be fixable, but
we also know that there is high competition in the solar market and the
modules that are made the cheapest will be popular and will likely not be
adequately filtered.
Sorry for posting to the AMSAT-bb but it is the only HAM email reflector I
subscribe to.
If nothing else, we need to find out what systems are terrible emitters and
nip them in the bud. Maybe all it takes is driving by solar systems you
see and turing on your AM radio on a weak signal channel and seeing if the
background noise peaks near that home. But also it has individual peaks,
so it might also be nice to tune around too find the max and then check the
range. I find the noise can go hundreds of feet along the power lines....
You cant miss em... just sounds like a 60 Hz buzz on all the harmonics of
the inverter switching frequency.

I don't want to be a pessimist, but I think HF (and lower) is history
anyway. If it's not this new breed of solar arrays, then it will be
something else. Residential noise levels are up so high in many places
already that HF is unworkable anyway. Even VHF is starting to suffer
from increased noise levels. The only hope is that any commercial or
government service using that particular part of the spectrum is
affected, then the solutions are available before you know it. Sad but true.
