Just a few errors. The QRN has been very low. What was the phase pattern? We seem to have some margin down to the limit, so there could be more QRN in the coming days. It will be very interesting to see how many days can be added to rise the SNR. There will be a limit somewhere i guess. So it is good to try that out before we start with undecodable messages (undecodable in a single attempt). The periodic actions remain active. Tomorrow, same procedure as every day. BTW, after completing the large 2970 Hz coil (including the variometer and drive motor) (waiting for dry wx to test it) i started to build another one for 8270 Hz and 700 mA antenna current. So then i can radiate about 400 uW there. 73, Stefan Am 11.11.2016 19:32, schrieb Paul Nicholson: > Stefan wrote: > > > f = 6470.00000 Hz > > Start time: 11.11.2016 08:00:00 UTC (Daily repetition) > > Symbol length: 60 s > > Characters: 4 > > CRC 16 > > Coding 8K19A > > An easy copy: 'TEST' Eb/N0 = +3.9 dB, BER 31.25% > > Carrier S/N: 16.0 dB in 35.9 uHz > : -62 dB in 2.5 kHz after blanking > > Error map http://abelian.org/vlf/tmp/161111a.gif > > -- > Paul Nicholson > -- >
