A little off topic, but the RTL-SDR.com v3 dongle does support HF without
up converting, and is inexpensive. They are a good way to play with SDR and
not spend a lot of money to do it.
As mentioned, it will shut down due to near by transmissions. I attempted
it on a linear bird one time with it hooked up to my Android phone and SDR
Touch app.

Hello fellow people of the birds,
Tomorrow (Feb 14) I will be returning to Alaska from a little visit to New
York. As long as all goes as planned, my intended flight arrives at
Anchorage at about 1400Z and I will have several hours on the ground there.
The BP41/51 line is on the airport so I'm planning to head over there, or
at least activate both grids separately (there are parks either side of the
line). Weather looks like it should cooperate, hopefully. Ops will probably
more centered around BP51, but I'll try to do as much from BP41 as
possible.
I will have info on specific passes on my twitter more near-in,
@???????????. I'll be back to ninja-portable on this visit with my
FT-817NDs.
73,
Gabe

I would expect any major airport would be very interested (not in a good
way) in someone waving an antenna around at the sky, talking to people
in strange places. Be careful...

Weekend

Content-Type: text/plain; charset=UTF-8
Hi Folks!
"VE3HLS Heavy" will launch this Friday morning for Quebec.? Below is the
schedule for this weekend's activities.? Note that I have included several
FM satellite passes despite my grumbling on my last rove.? I promise to be
there and ready for those passes, but I won't think twice about pulling the
plug if things are so unruly that I can't get a word in edgewise.? If you
can govern yourselves accordingly then maybe you will score a few new grids
that get activated very rarely, if at all.? It's up to you.
As always, the weather dictates what actually happens.? The trip to the
FN39/49 boundary is 2+ hours on what appears to be an unpaved logging road
(I'll find out when I get there).? I have found that Quebec keeps their
roads very well plowed in winter.? Hopefully, this will be the case here
too.? The weather forecast looks good, so I am hoping I won't have to invoke
the Weather Permitting Clause of my service contract to the satellite
community.?
I had planned to activate FN46 for VE2FU, who needs his home grid.? It turns
out he won't be able to get on the air so we have put that plan aside.?
However, please get back to me if you do need FN46.? We can do it early
Saturday morning.
Now, the good stuff.? As always, if I have left your region out of my
schedule then please get back to me.

I'd rather not wade through the process of downloading and installing the
various multitudes of compass apps to see which of them can indicate true
north (handy for doing satellite demos when you're not at home, and don't
know or don't have the magnetic declination of that location).
My phone doesn't seem to have a magnetometer anyway (from the error
messages I'm getting when I've tried a few compass apps).
Do any of these apps use GPS to show true north, and not just magnetic
north (or both)?

P.S. I have an Android phone and tablet, but I'm sure iPhone users could
find this info useful as well.

GPSTEST, droid, will allow you to disable inclination therefore showing you
true north. It's a free app.

In most areas, the difference between true and magnetic north are of
little consequense for LEO satellite communication. Now, this is not the
case for terrestrial navigation, but aiming towards a satellite, either
number will work and you will be able to correct by listening to the best
signal.
The simple solution is to buy an inexpensive compass. One more piece to
schlepp, but not to big nor heavy. Unless your compass is one where you
can change the display, it will give you the magnetic north. And like I
said, you really don't need to know the local declination and do any math
for your purpose.
You can also orient yourself with a map, matching it to your surroundings.
There are many other McGiver ways to find north, get a compass, KISS.

Subject: [amsat-bb] Smartphone (compass) apps which show true north?
I'd rather not wade through the process of downloading and installing the
various multitudes of compass apps to see which of them can indicate true
north (handy for doing satellite demos when you're not at home, and don't
know or don't have the magnetic declination of that location).
My phone doesn't seem to have a magnetometer anyway (from the error messages
I'm getting when I've tried a few compass apps).
Do any of these apps use GPS to show true north, and not just magnetic north
(or both)?

P.S. I have an Android phone and tablet, but I'm sure iPhone users could
find this info useful as well.

First result on a google search for ?android true north? is
https://play.google.com/store/apps/details?id=com.q9tech.tool.compass&hl=en
As far as iOS users go, the stock compass app has a true north option.
