iPhone Interface For Ham Radio Mates Old With New 51
jjp9999 writes "By using the same technology found in older modems, Thomas Tumino, vice president of the Hall of Science Amateur Radio Club, has invented an iPhone interface for ham radios. He told The Epoch Times, 'Today there are iPhone apps where you can use the systems in the phone — and its sound card, which is being used as a modem ... And then you connect that into your radio with an interface like this, that just isolates the telephone from the radio, and then you can do all sorts of things.'"
SDR (Score:5, Interesting)
I went to a Maker Faire a few months back and started talking to some HAM radio operators. They told me that far from a dead activity, they have actually gone digital, incorporating the Internet to connect to transceivers for when they aren't able to have an antenna in thir back yard. One other technology mentioned was SDR, otherwise known as software defined radio. SDR means that the necessary hardware is simpler, with the majority of the signal processing now in software. There is an SDR app for the iPhone, but you need a piece of hardware that plugs ino the antenna and also plugs into the headphone jack of the phone. I haven't looked at Android, but I imagine you could use some form of GnuRadio.
