Paul 61 material ferrite will give higher Q than -2 powdered iron at LF/MF. Nothing wrong with -2 powdered iron ... it's just 61 material ferrite offers superb Q. I wouldn't recommend any of the lowe
Alex I haven't looked at your 136 kHz list in a while ... it was quite a trip down 'memory lane'! Your work on the list is much appreciated. Jay W1VD WD2XNS WE2XGR/2 -- Original Message -- From: Alex
Joe, Paul Works good here on both XP/SP3/Firefox and Win10/Firefox. Impressive stuff Paul! Jay W1VD WD2XNS WE2XGR/2 Sadly this appears as boxes with a blue background without spectrogram. Is there so

Stefan Yes ... first EbNaut decode for me. Antenna info at: http://www.w1vd.com/modifiedeprobe.pdf Have been using this antenna for many years for general purpose VLF, SAQ etc. Jay W1VD WD2XNS WE2XGR
Paul Paul, W1VLF, lost interest in the band ... there wasn't much going on in 2010. Unfortunately, the BIG coil has since been decommissioned. Jay Well done, the 3rd station in USA able to decode EbN
Stefan Probably should have added 'on this side of the pond' ;~) . Anyway, Paul W1VLF could only attract the interest of one receiving station (me) at 3 miles distance. Jay Am 03.01.2018 15:49, schri
Thank to Markus for pointing out the 4 cycle SpecLab latency ... with that I was able to improve the W4DEX decode from the other night to Eb/N0 5.9. found xxx list rank 0 reference phase 180,180,180,
Joe Please verify the new EbNaut start time was 2140 UT. Previous post to Stefan had 2040 UT as start time. Tnx for the signal! Jay W1VD -- Original Message -- From: <[email protected]> Reply-To: <rsgb_l

Paul The path from VO1NA to Burlington CT is only 589 kM ... and it's mostly over water. Have been attempting to decode VO1NA for a couple weeks now (both 2100 and 0900 transmissions) and only have t

Ward It appears that your carrier was easily received in CT last night. Using the same file as Stefan's transmission your carrier (*) was detected immediately at the 0,0,0,0 phase trial ... and impro
Ward Glad to hear a message will be in the works! Some sites have it as ls and some as ms ... we're right on the line. Ls is the one. The actual coordinates are on my website. Jay -- Original Message
