Why did I see the Fox send several CQ and then disappear completely from view while the Hounds are still there? Initial Fox CQ calls are made using full power for one signal. The Fox works Hounds using several tone frequencies simultaneously with a reduction in signal strength for each signal. If the Fox uses 5 channels this reduction is 14dB. ===== Well that was my experience on 40 metres. I saw a couple of CQ from Fox at a respectable -18 and responded accordingly adding my voice to the many baying Hounds. Fox may well have heard me and responded (though probably not) but once he switched to N channels I could not copy him at all. Nevertheless I kept trying for several cycles, therefore adding to the QRM, as I had heard the Fox with what would normally be a good margin. The final paragraph of Fox instructions should be read by Hounds, (though many obviously don’t read). To reduce Hound QRM I believe the initial Fox CQ ought to be sent at a similar power to that going to be used for working traffic. If N is varied automatically according to traffic rates it should not be increased rapidly as QSO that have started are going to get dropped. I guess it should start high and reduce slowly as traffic reduces.
