Yesterday I setup an alternative server that replaces the Worldstation server. For now this server was hosted on a pc within my local network. The radio found the server without any problems and loaded the “Worldstation” lists as usual. It did not have a clue about the fact that the lists were hosted at an alternative location. Of course I changed some of the lists to include my personal favorite stations that are not on the Penbex server (including vtuner links). The radio had no problem with playing any of the channels including the additional ones from the lists that I hosted. I discovered that the additional stations that I added to the radio’s internal “favorites” list also stayed available after switching back to the official Worldstation server. From this test we learn that it is possible to have stations in favorites that are not on the Penbex server and that we can use alternative servers. Good news I think.
For the local server I used a simple Windows XP notebook with additionally SimpleDNS and WampServer software. I used Wireshark to check the network traffic and verify the requests from the radio. The only change I had to make on the radio was the DNS server address in the network settings menu. I simply changed this to point to my local server.
It appears that the “favorites” list is saved inside the Radio’s memory. Possibly in the small 24c64 EEPROM which for sure limits the number of possible entries. The other “Worldstation” lists are loaded from the server each time you navigate through these lists. The structure of these lists is fairly simple and it is possible to extend them. You could for example add a “My Favorites” section to the regions selection screen. You can even sort this list..
