Yes, same here. It just takes a few minutes until everything works as expected. Running Firefox under Win7 32-bit. But then, very well! Impressive! And time to leave a trace there again.. 73, Stefan
Yes it has to download 1.5 Mbyte of spectrum data to fill the screen. It's throttled by my ADSL line. Unfortunately, security restrictions prevent me downloading data from a site other than the one t
15 seconds initial download to Firefox here, quick hour/date scrolling thereafter. Looks/works great! 73, Jim AA5BW Yes, same here. It just takes a few minutes until everything works as expected. Run
I've installed fbins on my VLF stream server, it should be much quicker there. Plus, I've altered it so that it displays as it downloads, so it isn't just sat there appearing to be doing nothing. htt
New H rx under test http://abelian.org/vlf/tmp/171216a.jpg with the box on the left injecting a calibrated current in parallel with the dummy antenna. This is an end-to-end test: antenna to sound car
Hi Paul, looks good. I'm using the same waterproof box for the stuff on the tree :-) What type of isolation transformer are you using? Datasheet? Distributor? As soon as the decode of the 3 char mess
Thanks. 5170 will be a good test of the new rx, the current rx is consistently bad at that frequency compared with E. Last night was -11.0 dB at Forest, stacking brings us up to -2.5 dB. PS, the spe
All my receivers use Walters OEP transformers, A262 range which are available from many places. For isolation, A262A6E at the output of the rx's line driver and A262A7E at the house end. The input t

Hoping to try the new H rx on the loops tomorrow (Wednesday), so there'll be a day of interruptions. Only one anomaly so far: noise measures .088 fT with the gain boosted to make the measurement easi
New H rx in operation since 12:00 today and calibrated for phase. The two channels are very closely matched, only 0.1 degree phase difference at 8270 Hz! Not amplitude calibrated yet but my guess of
Some amplitude calibration runs on the H rx yesterday around midday. At the same time measured the cross-talk between the two channels. At 8030 Hz: N/S to E/W -58.7 dB E/W to N/S -44.2 dB which is a

Well, not very good. S/N of the daytime signal is poor and H-field S/N is worse than E-field, as it was with the old rx. But sufficient for some rough measurements. For the first time I put all the

Very nice indeed. Thank-you Paul! Joe VO1NA I updated fbins to version 4.0a to include a spectrum plotting function http://78.46.38.217/fbins3.html Draw a measurement box over the spectrogram and you
Varying the E/H mix on recent carriers and EbNaut signals fails to improve S/N when I move away from the calibrated mix. That's a good sign but it's not quite right yet. Measured E/H is tending to co
New fbins: reload to use Version 4.0b. Earlier versions will receive no more data. Now uses the latest calibration. Also lists measurement box and spectrum plot in the URL, eg Joe's daytime signal to
Hi Paul, VLF I'm checking your description of audio transformers in use at your receiver and making my wish list for the three kings ;-) Would you please confirm some details? As you mentioned earlie
