Hi Domenico, VLF,

OK, then i will try a new attempt for a first EbNaut message to south Italy. There will be improvements at RC4HAA this weekend, so more carriers will be required then. You can use the chance to receive them as well, in a few days.
But for tonite:

f = 8270.100000 Hz
Start time: Wednesday 029.Mar.2017   18:00:00
Symbol period: 30 s
Characters: 2
CRC bits: 21
Coding 16K21A
Duration: 7h, 4m
Antenna current: 700 mA

73, Stefan

Hi Stefan,

first of all, congratulations for the achievements on ULF. Great job. A milestone for the future OM activities on these VLF/ULF  bands!
Many thanks for the 8270.005 kHz signal of yesterday. After your announcement, i have activated my rx setup at about 23.00Z :

It is a 47 uHz BW grabber centered on 8270 Hz with GPS 1pps calibration. The first waterfall pixels appears today on early morning.

Looks like there is some straight line on your QRG, but most probably it is an artifact.
Hoping in a "quite" night as the last one, can i ask you another "only-carrier" session prior of  EbNaut ?

I'm in touch with Max ik0VVE and sure we can manage EbNaut decoding from his site.

Again,  many thanks for your activities.

Hi Max,

What about a new attempt for your first EbNaut message? The signal should be strong enough. Are you ready?

Hi Stefan & friends,

despite the heavy local noise (that I'm trying to solve...) it seems that your signal is coming to my poor system that has been collecting a couple of your electrons..., HI.

Thanks for transmission.

Oggetto: LF: New carrier on 8270.005 Hz

Hi all,

Just in case someone new or old wants to try, i'm running 700 mA again on 8270.005 Hz until 05:30 UTC.
It is a first test for a new RX stn on VLF! If the trace will become visible, it would be a new personal distance record < 9 kHz for me :-)

It is still to early to hope much, no GPS module is available so far.

But i can tell you i have been in contact wil RC4HAA (club station) in LO53CF! See their grabber (running on VLF since a few days) at
A GPS module with PPS+NMEA will be available in a few days...

73, Stefan
