>> .. thinking about 1.2Ghz radios providing 128Kb of data. The effective rate of the ID-1 is generally quoted as 60 to 70 Kb.. The "coming this fall" UDR56K-4 will give close to that performance. http://nwdigitalradio.com/ Considering it's running more power and is on 430 MHz instead of 1.3 GHz it should be giving us significantly better range. 73 Bill - WA7NWP
