Fixing some issues in Gpredict

Update: after installing the new version, it can no longer engage with my TS-2000
via rigctld. Need to look into it as to what changed there. So for now it’s probably
better to stay on 1.3 if you’re using rig control.

In the past I had some issues with Gpredict when tracking a satellite and having
Gpredict control my TS-2000. Mike K2MTS reported a similar problem on the list
hosted on Sourceforge, that his FT-847 would flip-flop between uplink and downlink
frequency. I saw the same problem with Gpredict 1.3 on my TS-2000.
Alexandru OZ9AEC submitted a fix to SVN and I finally got around to check out the
new code and bring my version of Gpredict to 1.4svn which should solve that problem.


Installing TrustedQSL on OpenSuSE 11.4

One thing I really like to use is LoTW. Not to replace a paper QSL card which
I still enjoy, but to quickly confirm contacts especially when needed for awards.
Some distros package TrustedQSL which is the application used to send your
QSO data to the LoTW servers, OpenSuSE apparently does not so you have to
build it yourself.
First you need to download the source code for TrustedQSL and the tqsllibrary
tqsllib library download:
TrustedQSL app:

Once you downloaded the source code, unpack the tqsllib file and run the configure
script. In order to compile the library you need to have a complete build environment
including expat. To build the TQSL applications, wxwidgets needs to be installed. The
steps are the same for both packages:
mschulz@shack:~/Downloads/tqsllib-2.2> ./configure
If successful you can build the library using make
mschulz@shack:~/Downloads/tqsllib-2.2> make
After a successful run, you need to install the library as root
mschulz@shack:~/Downloads/tqsllib-2.2> sudo make install
If you’re starting fresh with LoTW, you can refer to the documentation on the ARRL
on how to request your certificate. I already had a working installation on
Windows that I was using with HRD so I copied the TQSL directory from my Windows
installation into my home directory under Linux. Simply copy the certs and keys
directory as well as the config.xml file into the .tqsl directory in your home and you
are ready to use LoTW with TrustedQSL.
