2017-04-10 Amateur radio callsign lookup on Android without needing Internet access 10 months ago
Earlier I had the Android application Ham Radio Prefixes - Android Apps on Google Play installed, but it needs some server on the Internet to look up callsigns and determine the country it is assigned to. Sometimes I need to do a lookup off-line, and I noticed fldigi and CQRLOG do that fine when the country data file is installed. So it can be done, I just have to find software that does this right. On ICQ Podcast Episode 234 - Portable Power Distribution and I heard mention of Pocket Prefix for Android which can be found at Pocket Prefix - Android Apps on Google Play and which works off-line. This was even mentioned on the podcast as one of the advantages. It even gives extra information when available, the given example is that prefix SV is for Greece but SV9 is specific to Crete. Or EA9 is specific to the Spanish enclaves Ceuta and Melilla which are located in Morroco (and therefore count as a contact with the African continent). It's a nice application, thanks to Derek Turner G4SWY!
