 Super Tropo on 2m Now
Worked EA1 and F6 all S9 with a tiny 7el here.
Band is open to EA all day

 Re: Super Tropo on 2m Now
The tropo shows up on Hepburn but here is nothing here. I suspect that the boundary between the high and low pressure areas is in that region. You'll be sending me another update. Have fun. Cheers Tony

 Re: Super Tropo on 2m Now
Got on a bit late but worked Wiltshire from Ruislip 5-7 so pretty cool and just now worked Bogota on 20m also heard 1 MM3 and 1 M6 cornwall got Q5 an Zero S reading from Colombia but he was 8000ft ASL great dx for 130am Cheers Regards Damian

Zero S reading would imply that there was no signal. In that case you wouldn't be heard. The meters on most radios are meaningless so assessing the strength on a signal to noise basis tends to be more meaningful. Nothing too out of the ordinary here. PI7CIS - 500km - beacon is up a little and 2E0NEY - 190km - was a good 59, a bit above normal, when we had a chat earlier. Hopefully things will pick up later. Rare for me to bother with HF here. Cheers Tony

Cheers Tony It just means their signal isn't strong enough to register on the rigs meter, one could guess backwards I suppose that they'd be registering 0.3 if the meter was sensitive enough to show it. I feel bad enough giving Zero reports without going to those extremes.

No signal, no information can be passed. 51 is rare enough, in reality, as anything that weak is likely to be disrupted at some point and become 41. Cheers Tony

 Re: Super Tropo on 2m Now
Thats why I explain that "you're not showing on the meter BUT you're readability is 5".

There is a standard and I have thought of re-calibrating mine but, in the end, it's too much trouble with too many variables relating to pre amps, transverter gain etc. To that end I use the "educated guess" method which is related to the perceived signal to noise. I work on the basis that a report has to be a whole number so, if a QSO happened, the signal strength must be, at least, S1 as S0 would indicate nothing heard. There's plenty, on the web, to indicate how poor the calibration of amateur equipment is. Cheers Tony

I did say signal strengths were always given in whole number. I bet you've never given a report of 5 by 0.5. Quote: The S stands for "Strength". Strength is an assessment of how powerful the received signal is at the receiving location. Although an accurate signal strength meter can determine a quantitative value for signal strength, in practice this portion of the RST code is a qualitative assessment, often made based on the S meter of the radio receiver at the location of signal reception. "Strength" is measured on a scale of 1 to 9.[3]
1 Faint signal, barely perceptible 2 Very weak 3 Weak 4 Fair 5 Fairly good 6 Good 7 Moderately strong 8 Strong 9 Very strong signals
S 0 = no signal. If it's less than you are not going to derive any information from it. The baby is 9 months old when it pops out. Cheers Tony
