Re: [digitalradio] 14100.5 kHz USB - ALE Channel Bandwidth, IARUBeacon Guardband
You do have a problem then. I don't As I don't have a waterfall or sound card and can't click on a thing. Therefore - again - if I say meet me on 14,075 you will be right on with my mark & space tone with 2125 2295. Now if you have what ever you run way off the standard you will have to look for me. Its so easy Ray Charles could see it... And yes I do have the same tones time after time after time. It never changes. I think you see why I *can't* use a waterfall frequency now.

Re: [digitalradio] 14100.5 kHz USB - ALE Channel Bandwidth, IARUBeacon Guardband
But- what is default offset? Not everyone has the same thing for an offset. It is determined properly, by simply starting on one end of the waterfall and clicking every 100 cycles, and transmitting and observing your transmit output. Where the RF output is the highest (from the sound card - which drives the rig at its highest power) that is your sweet spot on the soundcard, and where you offset should be set. Every computer sound card I have used has had a different spot where that happens. My present one happens to have its highest curve setting at 1 kc, but others have been much lower, and some much higher. RTTY IS easier to find, but if someone gives me that stupid 14.070 freq, and I go to it (14069 on the VFO plus 1 KC on my sound card), very likely there is NO signal on that freq. But, there are dozens above it, so which one is he when I go there? I have to individually go to each one, one at a time, and copy till I get a call readout, or in my case - using WinWarbler I have wideband copy, and go to that window and search down until a call has indicated where he is. Its just so much easier to use the correct freq in the first place. I dont care where your VFO is, or what your offset is, and you shouldnt care where mine are either. If you spot 14.07380 and I click on it, that is where my program sets my tracer to copy the signal there, and I have the target copied immediately. If you tell me 14.071 in the freq column, and then put a note in "+1280" , my CAT control is still going to set my vfo to 14.071 and then the waterfall tracer will be up 1kc from that, putting my trace on 14.072 which is still 1.8 KC off the target- and there will be a dozen signals between my tracer, and the real station. This is the reason we should all use the waterfall freq, not the VFO freq, and should train new ops right off the bat, so there is no confusion.

It makes sense if you are running "true" RTTY AFSK tones of 2125 / 2295. Or any mode for that fact. If you are using default offset I will find you on any dial frequency you may give.

Re: [digitalradio] 14100.5 kHz USB - ALE Channel Bandwidth, IARUBeacon Guardband
It just doesnt make sense to give someone the incorrect frequency when spotting a digital station. Nor does it make sense to give them a VFO freq, since we all know that the station IS NOT THERE. It is the VFO plus the audio card freq added together. That is where we will find the digital station, no matter what rig we have, or what our offset freq is. I really detest seeing someone giving a vfo on the spot, and giving a offset to add to it, in the notes. Just give me the freq. I dont care what your vfo or offset is. Mine may or may not (probably not) be the same exact things. But you can bet that if you give me the vfo plus offset as one figure, that when I click on it, my CAT program will put me on top of the signal, and I can read it immediately, without having to look around at a dozen different signals before I can do so. It is the same with CW signals. I may have 800 cy offset , and you may have 600 or 759, it doesnt matter. If you are using a waterfall, and I am, the signal will be right where we want to copy it. If not using a waterfall/computer readout, it will still be in the correct place in our earphones. Danny Douglas N7DC ex WN5QMX ET2US WA5UKR ET3USA SV0WPP VS6DD N7DC/YV5 G5CTB all DX 2-6 years each .
