Yes. I've been in email contact with him (having built his LF converter in 2003) before some months and asked why he didn't at least stay at LF since there are no contests and no SSB and so. Here, th
Hi Daniele, OK, i will set up the usr file. But it is nothing special, since we want to display the sferics, we won't have a blanker and/or clipper and no filtering and no sample rate drift correctio
Now i have added a wav (audio) file of the SAQ message of last sunday. Very fine CW reception. Even the carrier during key-up was audible... I used a 300 Hz CW filter and a noiseblanker (15 dB trigge
Dear VLF, i have created a google earth picture where my current VLF receptions in DFCW-600 (sri, just above 200 km) are displayed, so one can get an impression of the different locations, distances

Hi Daniele, Yes, adjust the B slider. But the QRM/QRN must be totally visible on all frequencies. You can increase the input level but it's better to leave it as you usually have it. It is better to
I am pleased to have received SAQ the first time at all! Since i was not QRV on VLF last sunday i took a recording that is analysed now. SAQ is 40 dB above noise in 12 Hz FFT on my grabber. 73, Stefa
Hi Tony, Thank you. I am looking forward for that! Our distance is 1310 km (pic attached). Pse, what is your complete RX equipment? Do you have the settings for DFCW-600? Any noiseblanker and/or clip
Hi Roger, Nice that you are back :-) I assume you will spend the night by reading the older LF mails? ;-) Yes, maybe this saturday but it's still uncertain, as usual... 73, Stefan Am 19.10.2010 16:54
