PSKMail on 30 metres

I'm building a PSKMail server for my IC-745 and an old Celeron laptop (first harmonic's cast-off).

The ASUS laptop is booting the Lupu Puppy PSKMail server disk just fine.

You can download it here

http://hermes.esrac.ele.tue.nl/pskmail/liveCDs/puppy_pskmail_server-1.0.28.iso

The client will be a eee netbook and a codan 9323.

This setup can only work at freqs up to 10.140usb due to the fixed channels in the codan.

The tentative freq at this stage is 10.138Mhz USB.

Digipeater settings for VK6

The KPC 9612 TNC is being used to implement telemetry-capable, PARADIGM-compliant digipeaters in Western Australia.

Here's the configuration template being used to program them.

Note that using WAn-N in your path will produce the same results as WIDE used to do without tracing.

The new PARADIGM configuration means that WIDE now performs the same function as TRACE used to, and that the digi's no longer respond to TRACE at all.

Recommended paths are now:

Home stations VIA WIDE2-2

Mobile stations VIA WIDE1-1, WIDE2-2

Special Events VIA WIDE1-1,WAn-N

Home stations should digipeat the alias of WIDE1-1 this is the same as the old RELAY.

Telemetry prototype









Here's a look at the sensor board prototypes. This is the schematics
They're a bit rough still but hopefully they will be ready by tomorrow it time to be installed at tic hill.
any suggestions for improvement most welcome!!

Radio Mobile and APRS

this is how easy it is to get aprs information into radio mobile.
opens up some interesting possibilities for rf planning and design.

if anyone else thinks this is cool let me know.

another map


its from an old street directory so no copyright worries

heres the tiepoints tlh and brh
metromap.inf file sez:

enjoy. contribute some of your own!

Radio Mobile map



This free map should be usable with most aprs programs. YMMV.
Please let me know how you go with it.

Save it as a 514 x 514

The tiepoints are

TIEPOINT 513 513 116.1251 -32.17497

WARG Telemetry update

Ive got my hands on some CSLA2CF hall effect current sensors.

They look to be ideal for the job we want them to do, onsite power monitoring

These are a three pin device with the following characteristics:

Vs 6-12
Is 20mA max
I(sensed) 125A max
Voffset Vcc/2
Sensitivity 19.6mV/NI @ 8VDC
temp offset 0.02% / degC

I believe this means that with a supply voltage of 12V and the wire passing through the toroid without a turn (ie N=1) a current of 0A will produce an output of 6V
a current of 5A will produce 6V+5x19.6mV =6.098V.

Our KPC9612+ telemetry channels want a 0-5V reading

That pretty much sums up the interfacing requirements. looks like our 2:1 voltage divider will come into play again.

I'll be posting some pix and diagrams soon. stay tuned!
