Ron; The digital band plan being tested currently puts the D-Star outputs between 144.9 and 145.1 and the inputs 400 kHz down. This keeps everything in the spectrum designated by the FCC for repeater use. Since alternate input channels are inputs for analog repeaters, only 9 new channels resulted. At 500 kHz spacing, we would have lost the 144.9 to 145 channels as their inputs would have been outside the repeater allocation. The 9 channels should accommodate 15 or 16 systems in Northern Calif. by judicious channel co-ordination. We have 6 systems on this plan currently. It is necessary to use a 6 can duplexer to make the 400 kHz split play. The results of some testing using a reference antenna are in the tech log at www.w6dhs.org . Ernie W6KAP
