Further javAPRSSrv ports update (I know again!)

After some consultation with the T2 Sysops I now have my javAPRS mirrored like that of a T2 server, but without T2 status! (I need a fixed IP to become one) So here is the list of amended ports…

Available Ports

1314 Messaging Only Feed
8080 HTTP POST Submission Port

Available ports for javAPRS

Since changing from APRSD to JavAPRSServ the ports that one can connect to have also changed!

The old ports have been removed, leaving now only 3 to connect to and 1 HTTP port

1314: Message-only Feed

10152: Full APRS-IS Feed (limited to within 300Km of my location)

14580: User-defined Filtered Feed

14501: HTTP status page (this is the only port viewable with a web browser!)

you can telnet into the first 3 however the information you receive back won't make much sense unless you are using an APRS compatible application to interpret the data!

APRS uses AX25 to send and receive GPS positions, messages and objects for Amateur Radio use.

APRS 40m Gateway VK7HSE-4

After some extensive testing in Australia/New Zealand on 40m (7MHz) I have now setup a full-time 40m Gateway. The centre frequency for this is 7.034.300MHz (sideband irrelevant) so your TNC/Soundcard set-up will determine what you will need to set your radio frequency to.

The set-up for the Gateway is as follows…

  • Yaesu FT-847 transceiver (100w)
  • PK-232MBX (with DSP)
  • Hustler 5-BTV
  • Philips PRM-8030 (VHF)
  • MFJ-1270b (TF2.7b)

The software in use is Linux AX25 Kernel and Digi_NED v0.39 and APRSD for my I-Gate (VK7HSE-3) I would appreciate signal reports if this is possible!

40m APRS Trials

Recently on the OZAPRS mailing list there was the suggestion of setting up an APRS network on 40m (7MHz) this has been used successfully in New Zealand for some time and I have in the past attempted to initiate similar but with no takers! So what have I seen on 40m thus far? here's a screen shot of my XASTIR viewing the South East of Australia… UPDATE: the gallery plug in was removed so images are no longer available

TinyTrak4D as Sat-Gate for ISS

A few days ago I put my TinyTrak4D onto the ISS packet frequency of 145.825MHz.  Well was I surprised to see this morning some success !!!
