Thanks for the decode. The error map is astonishing clean! So 200s symbols to 30s symbols that's 8 dB and without the 6 dB QRP, here we are: 14 dB :-) Still some things to prepare for next tests. Need to finish the usage of 'Oskar' now, because it wil be much easier to add the remaining 2 yoghurt cups on the coil to get more L. I thought about the old times and the 46 km band. Not only i have been on 6.47 kHz these days, if i remember correctly it was DF6NM and OE5ODL as well. I would like to come back to that band for some tests. Maybe we can see a first tendency of advantages / disadvantages. 73, Stefan Am 03.05.2016 07:34, schrieb Paul Nicholson: > > Stefan wrote: > > > 130 mA > > f = 8270.1 Hz > > Start time: 01.05.2016 15:00:02 UTC > > Period: 200 s > > Length: 5 > > CRC 16 > > Coding 8K19A > > Copied 'VLFDX' > > Reference phase: constant > Eb/N0: +5.4 dB > BER: 26.8 % > Carrier: S/N: 19.77 dB in 9.8 uHz > Error map: http://abelian.org/vlf/tmp/160502a.gif > > I am seeing the expected 6dB signal reduction > at the lower antenna current. > > -- > Paul Nicholson > -- > >
