Do we have data from the various countries represented on this list as to the real vs theoretical probable role of Amateur Radio communications in disasters? My sense here in the USA is that most if not all high-speed critical and/or confidential traffic will be handled by government personnel using government gear on government spectrum. Amateur Radio will be asked to handle more of the non-critical peripheral communications. Generally speaking the Amateur Radio role here in the USA will not require wide bandwidth nor high speed modes. We really need to focus on improving coverage and efficiency and reliability using likely modes rather than getting too distracted by the bells and whistles of modes that are too rare and unreliable to be useful in a genuine disaster. WDYT?
Icom has broader filters to be installed instead of the existing smaller filter. We measured he existing filter to have a bandwidth of 2.9Khz. In out experimental links it showed that other factors like noise and interference were much more likely to slow down the linkspeed, than the actual bandwidth of the filter. By the way not all transceivers have 2.9Khz. bandwidth, most of them only 2.7Khz. Yes I agree, there exists a lot of nonsense about the speed item. Transferring football matches is not really a goal to meet in a thin communication channel. However as you know that a fast mode would permit more traffic been handled in an emergency situation.73 Karel, hc1akp
