APRS sats with the TH-D74A?
Is anyone using the Kenwood TH-D74A, say with an Arrow antenna, to work the APRS sats (ISS, AISAT, etc.)? If so, what are your thoughts? Is it worth a try? Steve AI9IN
Amsat has a article on just this thought....

There is many articles that are posted on the Amsat "Station and Operating Hints" page for many of the common questions and ideas on how to get started.

Steve,
The TH-D74 works well for APRS via satellite, with those satellites that work on one frequency or band. When the ISS digipeater is operational, I can work those passes with just that HT and my Elk log periodic. It has been a couple of weeks since I last worked an ISS pass, since that system has been offline. I'm looking forward to having the new radio system operational on the ISS, which should take care of issues seen with the current system in the recent past.
The TH-D74 worked fine with NO-84 and even NO-44 in the past. The only APRS digipeater satellite I can't work with just the TH-D74 is FalconSat-3, as that is cross-band (2m up/70cm down), and the TH-D74's TNC will only work with one VFO.
I have some files in my Dropbox space related to using the TH-D74 for satellites, including those with APRS digipeaters. Look for the "TH-D74A" folder at:
The AMSAT Journal ran an article on how to use a TH-D74 with the APRS digipeater satellites, which also covered the TH-D72:

In addition, I wrote an article for QST that had the settings that needed to be set to work the digipeaters like those on the ISS:

If the links get mangled in e-mail, you can look up WD9EWK on QRZ.com to get to other links for the articles.
