Joe Wasn't able to get set up in time for the 0000 and 0100 transmissions ... unfortunately no decodes at 0200 and 0300. Will be ready to go tonight at 2300. Based on receptions a couple weeks back 0
Paul So ... we're still stuck at solving the gate drive overlap issue. Your's seems to be slow to turn on and to turn off. Think I questioned back a while ago the driver circuit board 'trace' widths.
Joe, Riccardo Sorry ... last night there was high static levels so no chance for a capture. Even DCF39, which on a quiet night is quite strong audible copy, was just about completely wiped out by the
Stefan Will set things up. A quick check of www.lightningmaps.org shows significant thunderstorm activity over southeast US. The storms are associated with a large frontal zone so they'll probably ha

Joe, Riccardo I didn't see your signals on EU grabbers last night so the receiving setup was turned off. Unfortunately, we missed one of the quietest nights since mid winter ;~( . Looking at the wx m
LF EbNaut enthusiasts The wx maps indicate that tonight will be another quiet night on VLF/LF on this side of the pond ... in case anyone is thinking of putting 'fire to the wire'. (descriptive LF te

LF EbNaut enthusiasts Despite low QRN levels last night, there were no successful decodes. The path to Italy on LF has always been difficult from here. As Markus suggested, maybe the Alps have an adv

SAQ enthusiasts Copy of the 0845z transmission was poor due to high QRN levels. Copy at 1045z and 1245z was much improved due to lower QRN levels ... a slight edge going to the 1045 transmission. Eve
Saw the writeup in QST and immediately noticed the receive two-tone, third-order IMD at 2 kHz spacing is 60 dB and at 75 kHz spacing is only 74 dB! Good luck with that if you've got strong signals at
Andy Maybe I can shed further light on my comments ... The ARRL receiver measurement system was developed by Wes Hayward of Tektronics back in the mid 70's and has been used with minor changes since.
Rob Wondered why copy wasn't 'off the charts' last night. Forgot to add latency and TX delay to start offset ... doh! With the corrected start offset the results are more in line with expectations. S
