WSPR rides again

Nice to be back on WSPR on 40.  Looks like there's more activity in Japan then before..   Quite a few captures in the 8000+ KM range.

Three Magic Wishes for Ham Radio - 2015

> If you found an old radio (tubes of course) in a pile of junk, rescued
> it and in the act of polishing it up a magic genie appeared and
> offered you any three wishes related to Amateur Radio - what would
> they be?
>
> Hold the ideas for a few hours and let's see if anybody agrees...
> (Hams agreeing - I did say this involved magic....)



My wishes:

1.  Every ham has at least one full function RF APRS station on the air..   APRS is pretty incredible and the future potential (Packet Plan 9, HamBox, etc) is even more awesome.

2. Sane HF digital.   Separate the computers and the human operators, double (at least - it's a good start) the spectrum for the computers. Remove all 'rules' on the computers.  If it fits in the bandwidth (30 KHz?) then it's allowed.

3. I had to think about this for a bit but I finally came up with a third wish.   That's a new license class.  Add a little annual charge. No CW required - as cool as that would be.   No test either.   Fill out the form, sign your name, send in the money - you're a ham. Limited privileges of course - I'm thinking that 2 meter band only  would be good.

Ok - back to work on Plan 9...

20145 Microhams Digital Conference notes and comments


March 21, 2015 at building 36.

add lots of good notes here...

SECN MP-02 Demo with N8GNJ

demo notes and thoughts here

After party - no pizza at Round Table but a Wetnet Geek Night dinner at Redmonds Claim Jumper.  Missed the pizza but it was a good gathering of the Wetnet group.

WT-700 Windows Tablet for $60


If nothing else it's a good way to learn Microsoft Windows 8..

Open Questions:

  • Where's a tutorial?
  • What is a good bluetooth mouse and keyboard to get.
  • Can it be used for serial by bluetooth with the AP510 APRS Tracker?
  • How would one power this full time from DC - perhaps 12V?  Would being on constant charge be some how damaging?
  • Is this a good APRS client for the full time DC powered APRS emergency application I'm working on?

Configuring Data Radios for 9600 baud



See the wiki:  (link coming soon)

Next Generation Unconnected Amateur Experimental Packet System


APRS is 20 years old and still using 25 year old technology.   What can we do different:


  • Remove the scheme of hard coded paths and hops like WIDE1-1.  Instead go to a purpose coded system or better yet - just eliminate it all together.  Let the network nodes, which we used to call digipeaters, do it.   They're better, smarter and cheaper.
  • These network nodes will tell the clients how to address their packets.  The system will be automatically configuring.
  • Servers, and even clients, can record ALL the audio heard on the channel.  It's a minimal amount of data by todays standards.   A user on the web should be able to click on a callsign and packet and hear just how it sounds.
  • Trackers (and even home stations) will take a web cam snapshot associated with every position transmission.  These will be web uploaded when bandwidth allows.  Possibly it would be a 360 degree panorama.
  • No data will be directly injected into the IS infrastructure.  Only what's heard on the RF.  All stations gating from RF to IS will be keyed with a secure certificate that's created either locally or at trusted sources such as ARRL's LOTW.
  • Stations may have an alternate frequency agile RF receiver such as one of the RT802 dongles.  This will allow automatic Direction Finding of on the air signals when queried by local clients.
  • much more to come

AP510 Tracker


Better all the time.   Radio, GPS, TNC, memory, thermometer, etc etc.   All for around $100 with Amazon Prime shipping.

Perhaps this will be the Ham Radio side of the Montana Lander...


2015-2-7  AP510 arrived at Zeus.  Downloaded files from the Yahoo group.  Watched helpful 9 minute video by Eric/KI4xxx - on how to configure hardware and software.
   *

Alternate download location for AP510 files

2015-2-8 Watched video again.  First pass at configuration.  Fortunately there were no issue on DLL's or serial drivers with my dated Vista laptop.

Visited 8GNJ - helped him set up his AP510.  His went fine - mine started acting weird.

Reinstalled Firmware in mine.  Now it's happy and acting normally.

2015-2-9 It's running.  Light turned solid blue for the first time while sitting on the car's dash.  Apparently that indicates GPS lock.   Note to self.  Beacons and beeps every 15 seconds is a bit much.  Reconfigure tonight to turn off beep and set transmission to nice sane 2 minutes.

2015-2-10  Reconfigured.  Changed SSID from -4 to -5 to be in sync with Herb.  The -5 is for 510..  Set beacon time to 125 seconds.  Turned off the beep.   Next time - turn off MIC-E to see what it looks like.  MIC-E is much shorter which is a good thing but we're curious how the packets are going to look.
