Well with 19.8 dB in 92.6 uHz, my currently running transmission is maybe to optimistic. Then we are very very very very close to the limit! http://abelian.org/ebnaut/calc.php?sndb=19.8&snbws=0.000092&snmps=&code=16K25&sp=4&crc=10&nc=30&submit=Calculate The parameters were based on: Am 14.04.2017 18:47, schrieb Paul Nicholson: > Stefan today is averaging 0.25 fT and 25.8 dB S/N in 69.4 uHz. ...but that was a very quiet day. But today the 5...8 UTC SNR is 19.5 dB, yesterday it was 17.4 dB. So maybe with some luck it is a quieter day and we can expect a bit more than 19.8 dB between 8...11 UTC. Fingers crossed... 73, Stefan Am 19.04.2017 10:28, schrieb Paul Nicholson: > > Stefan wrote: > > > The carrier will stay on air for at least 1 day, > > Here's the complete measurement: > > S/N in 92.6 uHz, absolute phase, flux density > > 20:00 to 23:00 19.6 dB +14.5 deg 0.25 fT > 23:00 to 02:00 14.5 dB -3.2 deg 0.22 fT > 02:00 to 05:00 16.5 dB +16.4 deg 0.18 fT > 05:00 to 08:00 17.4 dB +51.5 deg 0.15 fT > 08:00 to 11:00 19.8 dB +68.3 deg 0.20 fT > 11:00 to 14:00 19.7 dB +62.3 deg 0.19 fT > 14:00 to 17:00 18.9 dB +65.2 deg 0.20 fT > 17:00 to 20:00 17.5 dB +22.8 deg 0.25 fT > 20:00 to 23:00 12.4 dB +4.0 deg 0.20 fT > 23:00 to 02:00 17.0 dB +6.6 deg 0.28 fT > 02:00 to 05:00 16.9 dB +27.9 deg 0.20 fT > 05:00 to 08:00 19.5 dB +64.2 deg 0.20 fT > > Looks pretty steady with repeatable diurnal. > > -- > Paul Nicholson > -- >
