APRStk Automatic Satellite Monitoring



Satellite Packet Ops:

I just posted a new copy of APRStk for operating via the UI digipeating
Satellites and monitoring the others.

Run this with your D7 or D700 with just a 20" WHIP antenna over a ground
plane and SHORT coax and you will hear almost a dozen FM satellites over
30 times a day...     Look ma.. no hands!

The 20" whip is 1/4 wave on the uplink and is a 3/4 wave 7.9 dBi gain
UHF omni antenna on most downlinks.  It is the ideal simple Satellite
OMNI antenna.  With it, you should hear most of the 12 FM satellites when
they are above about 25 degrees..   This is only about 1/3rd of all access
times, but it is automatic and simple.  A nice way to leave the rig when
it is not doing something else.

AND this antenna can be at ANY level, since it only needs to see the sky
above say 20 degrees.  No need to go higher (and add lossy coax)...  On
the roof of your car is perfect, or just outside your window...

APRStk will automatically do the following:

* QSY and doppler track AO27 and UO14 so you can hear QSO's
* QSY and doppler track UO22,KO23,KO25,TO31 PACSATS and capture STATUS,
  the PBlist, TELEMETRY and any other UI packets (No BBS traffic)
* QSY and Doppler track SUNSAT and work other stations via SUNSAT
* QSY to the ISS downlink & work other UI stations if PACKET is enabled.

Sorry, it was written to take advantage of the single serial port Radio
and TNC control built into the Kenwoods.  Use WISP for all other radios.

download:  ftp://tapr.org/aprssig/dosstuff/APRSdos/astk-exe.zip

The above file contains the APRStk.EXE and all support files.  Unzip it
into an existing APRSdos directory using PKUNZIP -dn or Winzip.  It is
just the new EXE and new support files, and must run in an existing
APRSdos structure.  Be SURE to read README\APRStk.txt in the readme's.

If you don't already run APRSdos, then download and install APRS848.zip
first from the same site.  

Enjoy...
