JASON is reasonably robust, but with no forward error correction, would be in a much lower category. Take a look at: http://www.w1tag.com/600M_Modes.htm for some thoughts on what Jay and I have been playing with over here. The bandwidths of some of the modes may strain the rules of propriety -- your call. If you want to try JT2, I can furnish some hints that worked well at the TX and RX ends in our tests. John Andrews, W1TAG > DD7PC has suggested JT2, which I don't know much about > yet, and I2PHD's "Jason" also seems like a good candidate. Any other > suggestions or comments?
