APRS over Satellites

APRS Digipeating over satellites:

Using a Kenwood TH-D72A HT to send and receive APRS messages through satellites

I will attempt to document confirmed satellites, along with the correct path, frequencies, and any other relevant information.  Trying to locate accurate information in one place is next to impossible, either the sites are out dated, or only give partial details of what is needed to work these satellites.  I found it difficult without experimenting myself to really see what works and what doesn't.  I will post my results as I continue experimenting.

  • NO-44 (PCsat1)
  • ISS

Reference for VHF/UHF amateur radio FM simplex frequencies for 6 Meter / 2 Meter / 1.25 meter / 70cm

I've compiled some suggested channels and frequencies to use on these bands

Try something new, these frequencies should be stored in every HT or mobile.  I enjoy messing around with VHF/UHF radios but repeaters usually bore me.  These frequencies are compiled from the ARRL "official" band plan as well as other forums and sites I have come across over time.

APRS services

Fun things to do with APRS

Email, Text Message, Callsign lookups, are only a few other things that you can do with APRS.

GPS tracking is a well known use for APRS, but there are many other things you can do with your radio and using the APRS network.  I've just started experimenting with APRS with my Kenwood TH-D72a HT dual band radio and wanted to document a few things I've been playing with.

Send email with APRS

Using a Kenwood TH-D72a HT to send and receive email via APRS

There are several ways to send an email using the APRS network.  In these examples I am using a Kenwood TH-D72A HT radio that has a built in TNC but you can certainly use this information to send emails using whatever APRS setup that works for you.

Kenwood TH-D72a - APRS Quick Start Guide

Here's a quick start guide to start using GPS and sending APRS beacons

I plugged the HT into the supplied wall charger included with the radio and left it overnight.  Now I want to start having some fun.  I will be using either MCP-4A or Chirp software to program local repeaters, simplex, FM sat frequencies, but before that I want to turn it on and tune into some APRS.

Purchased a new Kenwood TH-D72A HT, here's some basic info

I compiled some firmware/software/mods/etc together to get you up and running with this radio. 

After trying to pick one up on eBay for the past 3 month or so, losing every auction, I finally gave in a purchased a brand new one from Ham City

2014 Hamfests, Illinois and surrounding areas

2014 Illinois and surrounding areas Hamfests schedule.

A compiled list of local area amateur radio hamfests for 2014 for Mchenry, Lake, Cook, Kane and other surrounding counties in Illinois and Wisconsin. 

Hamfests can typically range from a small outdoor flea market style with only a handful of seller tables packed with boxes of junk found in their basement to a huge indoor/outdoor venue with a goldmine of antique radios, manufacturers selling brand new stock at discount pricing, every electronic part to fill in the gaps for your next project, antennas, coax and connectors, old and new radios, computers and anything thing else that can be useful in your ham shack.  The larger venues also can include food, raffles, and door prizes.  Parking and admission varies but is usually very affordable.  Just like your typical flea market, prices on equipment vary across the board and deals are typically to be had at the crack of dawn.
