Re: LF: EbNaut test at 8270.00332 from JN64bw

Hello Riccardo,

I'm sorry, i can't watch out for you in the moment. My tree is not available. It seems to have a problem. I need to maintain it soon. But there is only rain :-(

I see your antenna current is rising daily. Be careful!

For better EbNaut results i would recommend to use a longer transmit time. If you expect to be copied in a range of 1500 km, you could start transmitting at 15...7 UTC these days, i.e. 16 hours, because these are the longest nights in the year now. So you could go to 60 second symbols and gain 3 dB.
Do you have a safety system that stopps the transmission if something happens? How do you sleep at night when the TX is running? :-)

73, Stefan

PS: Yes, VLF is a wonderful place to play in. And the best: It never stops. The wavelength you are surfing on can reach an infinite length :-)

Hi Paul, Stefan, Jacek, VLF

I'm on air with continuous carrier at the same QRG until 21:30 UTC, then:

f = 8270.00332 Hz
Start time: 21:30:00 UTC
Symbol period: 30 s
Characters: 3 (repeated)
CRC bits: 24
Coding 16K21A
Duration: 8h,16min
Antenna current: 390 mA

Thanks Paul for your explanation.

It's all true! I thought it was so hard to do. But it wasn't! :-)

In my view, VLF are probably the most wonderful experience in my ham activity.
