Just over a decade ago Peleg 4X1GP gave a good presentation to the annual AMSAT-UK Colloquium in Guildford that pointed out that OFDM was the way ahead for Amateur communications.
Well 10 years later the first OFDM Amateur transceivers have been announced.
Doodle Labs have announced a range of 64 QAM OFDM Transceivers for the Amateur bands above 420 MHz.
The 420 MHz transceivers feature speeds of up to 12 Mbps and bandwidths of 10 MHz or 5 MHz, while data throughput of 48 Mbps is claimed on the 1240 MHz verssion.
Details of the 420 MHz version are at http://www.doodlelabs.com/products-and-services/amateur-bands/420-450-mhz-ba...
The others in the range can be seen at http://doodlelabs.com/products-and-services.html#Amateur
