Hi George, My own experience with those modes that can dig out signals from below the noise is they are too slow to be any use for much beyond "propagation studies". I am doing a very little bit of that on the 600 meter band. The typical story is set the radio and the computer and let it run all night (*ALL* night) to get a few words through IF propagation cooperates. Look at your results in the morning after breakfast. Not my cup of tea. YMMV.
Can the other stations hear you? If not..can you apply more power? (not already doing the limit) There are some antennas talked about here that might help you with receive. I have the small lot problem too but I am slowly working my way toward better reception and I'll be increasing power soon, too. Even with my puny station (25 watts!) I have worked some other stations on Top Band. I can hear better than I can send. Some people detest that there is digital activity on Top Band but it is there. Somebody else will have to point you at it (1840 or so?) as I don't use it. If you decide to join those guys let me wish you best of luck. 73, Bill KU8H On Sat, 2012-09-15 at 20:59 +0930, George, VK5IT wrote: > Hi Topbanders, > > > > I would like to bring up a topic which I suspect must be tantamount to > heresy among the diehard CW operators and that is the question of the use of > some of the digital modes on the "Gentleman's Band". > > > > It may be that CW can still hold its own by the speed and simplicity and use > of narrow bandwidths?? > > > > These dangerous thoughts have come about because a friend put me on to a > programme called Ham Radio Delux with its imbedded programme Digital Master > 780 which supports a whole raft of digital modes.
