Today I've been installing the G4HUP PAT kit on my FT-817ND transceiver. This kit is essentially a buffer amplifier that allows one to tap the IF of a transceiver, in order to send it to an SDR. Then, the SDR can be used as a panadapter. This kit is intended as an entry level SMD project and it can be fitted to many popular amateur radio transceivers. In fact, this has been my first SMD project, and I have found it quite easy to solder using the right tools and technique.
Gpredict stores the information for the satellite transponders in plain text files, one file per satellite. These files are called
.trsp files. The files shipped with the stable version tend to become outdated pretty soon, as new satellites are launched. However, the project's git repository is usually up to date.
The following shell script will download the files from git and install the
.trsp files in Gpredict's config path in the user's home folder. This can be used in Linux and probably other Unix-like operating systems. Something similar can also be done in Windows.
This is just an easy and temporary workaround to keep the transponder files updated, as Alexandru OZ9AEC, who is Gpredict's author, thinks of perhaps using an online database as a long-term solution.
