[OZAPRS] New Oncore RX interface.

[Chris Hill]

Hi Bob,

I've had a batch of double-sided PCBs made up to do the same thing.

These boards are double-sided, through-plated, silk-screened on the
component side, and have extensive ground plane retained on both sides, to
maximise RF Immunity (and minimise any RF spurii).

You can populate the left side of the board, for basic +5V and RS-232
conversion, or populate the right side of the board as well, to get PIC
support (for a Tiny Trak PIC, or build your own).

The bare boards are A$42 each, plus postage of approx $5 (probably get up
to
about 10 boards into a $5 package, but I need to double-check with
Australia
Post first).

I've been meaning to put a web-page together for a while now...  it's on
my
"amateur radio to-do list" for the Christmas holidays.

There's already 2 units in VK3, and 4 units in use here in VK6.


Let me know if you're interested.


Regards,



Chris vk6kch

Ron,
I am interested; what is the total cost please? I think I would like the
option of a separate 12v  power supply rather than from my txcrs, which
are
ICOM W2A and/or W21A. (I may even use the Yaesu VX-5R!!).  Have you
considered the type of battery pack configuration that is used for the
PAccom Pico packet....I thought perhaps those re-chargeable packs would be
relatively available, but there again, I am not a trained technical person
and dont know of the technical challenges.

How can I tell if my Motorola board is an Oncore GT+?  The serial numbers
on
the board are "Motorola 84D43579M02"...it also has a barcode "7U3PZ" and
yet
another stamping, "BM-XD, M473D".  The 10-pin plug is on one side of the
board at 90 degrees to it rather than others I have seen whhich are
parallel
to the PCB.
Cheers

Hi All,
         For those using the Motorola Oncore GT+ type GPS receivers, I
have
developed an interface that is the same size as the receiver board and
plugs onto its 10 pin plug. Spacers and screws are included to complete
the
mechanical arrangements.
          The board provides:
a) an RS-232 interface .. lets one talk to, and look at the GPS data from
the receiver.
b) a TinyTrak like unit that will connect to a radio thus forming an APRS
beacon in conjunction with the   Oncore receiver.
c) provides the necessary 5V power supply for the Oncore RX.

For more info, please contact me via e-mail or look at my web site
  http://users.mackay.net.au/~ron/       under APRS equipment .. its the
last item listed.

The simpler basic RS-232 interface is still available .. with details on
web site also.

Regards, Ron, VK4BRG.
