Hello Uwe, Markus, VLF !
 
3D""
 
I just took a "look back in = time" in my 2012 and 2013 log's (www=2Eqs= l=2Enet/pa1sdb) and I think over the last two years there is a large
rise in signal level when I take a look at DJ8WX his signal=2E The trace in some saved Spect= ograms in 2012 and 2013 are not that
impressive as they are right= now=2E 
 
Look at the trace in th= e spectogram above=2E Impressive !!!

I have to do research if those "glitches" are at the TX or RX side=2E=2E=2E
Do you recognise that glitch= at about 2 h Uwe ? (in your debug log ?)
I'm not at home this weekend= , so I can't tel you the exact time right now=2E

great signal = here, better than ever!

I had fixed m= y frequency offset and you were spot on 8270=2E004, albeit with occasional transmit phase glitches widening&= nbsp;the 42 uHz trace a bit=2E Sorry about the apparent 0=2E8 mHz up shift after= around 3 UT, it is an artefact caused by a too narrow settin= g of samplerate tracking tolerance (0=2E2 ppm)=2E
 
Thanks very m= uch for this test! It's a pity that Mal hadn't left his RX on overnight=2E

Hi Markus,
just now reading your mail=2E the switch off time was some min after you sent it=2E=2E
sri for that=2E
now the TX will stay on the air until tomorrow abt 0900utc=2E

Hopefully Mal reads this=2E
