*Edward,* * * *Now that the contest is over the bands should return to normalcy and by this I mean clean clear signals will again be heard.* * * *I wonder how many contesters were using SDR radios?....* * * *Listening to absolutely horrible audio and distorted CQ calls then a voice change when you work the station and find that the PTT audio is almost as bad. In some cases all but impossible to understand what the operator was saying.* * * *Yes the points are all that are important but when did that have to be the overriding factor above a clean signal?* * * *Certainly some stations were using software such as N1MM and wave files for their CQ Contest calls but surely they could take the time to ensure that their audio cables were not affected by RF, mic gain/ comp settings were correct for clear audio and the list goes on I am sure.* * * *One station here in VK was so bad I heard him call for 5 minutes without a response and when I suggested he had an issue he simply ignored my comment and started to CQ again.* * * *The stations in the contest in VK that I know use the K3 were all sounding great.* * * *Maybe SDR means true 'software controlled' with a box minus the knobs and buttons, but I think it would be a handful in a contest and I am not sure I want to place that much faith in a radio dependant entirely on Microsoft etc. A full Linux/Apple OS may be more reliable?* * * *The K3 to my mind IS SDR with a fully operational radio for those of us who dislike the mouse and function key style of operating becoming more popular and you have the option to add programs such as LP-PAN etc.* * * *The simple connections to a PC from the K3 are ideal for the way I operate but these days I have settled on N1MM logging and the K3 for everything else.* * * *I wonder if I am headed for the minority benches?..Grin* * * *I hope all those who played in the contest had a great time, after all, it is just a hobby and a darn fine one at that and enjoyment should be what it's all about, whatever flips your switch!* * * *73's* * * *Gary * On 28 March 2011 04:39, Edward R.
