The weak signal CW recordings on AB7E's website are well worth a few minutes to listen to. His recordings clearly demonstrate -- much more convincingly than any other demo I've ever heard-- the signi
Pro sound engineers have long appreciated this fact. It is well known that one dB matters when it is close to the level of interfering sounds, but not at all when there is no interference. I also str
Wow, this is very good Frank. I can't count the number of times I've been trying to dig out a weak stn and jokingly made the statement "If I only had ONE dB more of signal from the station"! What's p
Great stuff, pays also if you are a dxer to read old QST articles, one of these is "station design for DX" tells about what a DB can do, as I remember one quote from the article " 1db opens a whole n
It certainly is! This is quite interesting. How many hams have we heard over the years preaching otherwise? "But it's ONLY a fraction of an S-unit!". 73, Mike www.w0btu.com _________________ Topband
Hi, Doubling the power output translates to less than one "S-unit" at a distant receiver. Maybe most of those hams who preach otherwise ahve less interest in weak signals. That is a matter of persona
Bill - I am uncertain, based on your reply below, whether you are a proponent of worrying about 1 db or not.......so, from a 100% QRP op's perspective, saving 1 db, i.e., delivering 1 more db to the
I fully agree. It's when the S-meter isn't moving that a dB or two really matters! If we're 10 over 9 and in the clear, that's different. 73, Mike www.w0btu.com _________________ Topband Reflector A
I spent part of my engineering career designing satellite command FSK demodulators - including the deep space Pioneer Venus orbiter. To test the performance of them, we would mix the test signal with
Hi Jim, I think I wasn't really clear about that. I agree that each decibel matters. It matters for transmit AND for receive. Now *that* is clear:) The maximum power I have available to try and radia
