Wetnet Brunch Report 19-Sept-2015

Brunch is always great fun - even if they had no Banana Creme Pie this week.


WSJT-X now has an auto-qso mode.   What took them so long?

Good to see our wandering ski board friend on his seemingly annual visit.

MonWyDaHoTa - no, I haven't figured out what that means either.

Learned of the Gamma Research power supply.   Special feature is that it uses capacitor technology to supply the peak current needed for a 100 W SSB or CW transceiver - but runs with much lower rated full duty cycle construction. Pricey but a small size.

I shared that both of the Elecraft K3S stations at Summer Gathering were using the recommended PowerWRX 12V SS-30DV supply.  It has a small size and built in power pole connectors.   Should be a lot lighter in a Go Box than a 7 A or 12 A Astron.


I brought the Dash Cam I picked up a few months ago to try and get working.  Ren shared the well done Dash Cam reviews at Techmoan.   (No - I didn't get mine working.  It keeps power cycling like it's not getting enough current.  Time to RTFM.)

The "Periscope" streaming video AP was demo'd.


It's possible to Screen share (VNC) between Mac devices - but what about Airplay screen casting?  We experimented.  No definitive answer yet.
(Update de Jeremy:  You want to use Airplay to stream your screen to someone else’s monitor?  Try Airserver: http://www.airserver.com/Mac  I’ve used it a couple of times to use a Mac laptop instead of an AppleTV off of my iPad.)

For your notes - the magic code at Jimmy Jacks is :  J..J..sGu..1

Bob has a new 820T2 RTL SDR dongle running and is now a master of signal scoping.   He claims he can't decode the 9600 APRS UHF packets by sight but I'm not sure I believe him.

It does appear that SDR#, the main SDR dongle software, is indeed supported and hosted by the Airplay folks at their site.  Many have websites on how to get started but it's still confusing and not straight forward.

Onward!

It was fun!

Discusses Close out deal on Radio Shack 10' antenna masts.  Current prices is $9.97 - the .97 is key that this is a close out.   (NWP: at $10 these masts are a good deal.  Otherwise if I was working on an antenna project I'd instead use the 10' thick wall conduit from Home Depot.  A little more money but stronger.)

Ideas for Next Time:
* Cut and tune a full wave antenna and 1/4 wave matching section.  Compare it to a dipole.  On the lawn - with an AB switch for quick testing.

Wetnet Brunch Report 6-Sept-2015

First things first...

  BANANA CREME PIE

Average turnout...

Bruce was using a 6 AH LiPo battery.  Looks like the idea RPI UPS.   Ordered one.  It will be interesting to see if these new-technology batteries will work in the severe winter conditions of my  unattended property monitoring project.

Reminded to pick up some personal: ID Labels from Mavericklabel

... more RSN

APRS Packet DX

All absolute statements are wrong.  :)     There is a small chance that some unique DX packets will randomly make it through the system. This is, I would guess, what the K12 propagation website relies on.

Hopefully our next generation IS will preserve and make available dupes if only for local stations to enable better propagation studies and network management.

It's fun to pick out some DX packets...   Somewhere I saved the San Francisco region node broadcasts I received up here in the Seattle area during a similar lift a few years ago.
