Re: VLF: EbNaut transmissions on lower frequencies?, pre-tests: 6.47kHz

[Michel Brunel <f5wk@mterrier.net>]

Thanks Stefan,  VLF is a step toward LF, I'm planning to be "EbNaut ready" RX and TX  for summer on 137 kHz 

It's too early to conclude about SpectrumLab on Linux/wine. It looks like higher resolutions fail and systematically stay at 62% sample acquisition. I need time to investigate on this problem. 
I'm also trying to setup Paul's excellents vlfrx-tools. I just need to build a proper integrator for the 1PPS  in order to feed vttime with a correct pulse. (1PPS pulse witdh = 25 mS)

Hello Michel,  That is very nice to hear, thank you for trying. Welcome back on VLF :-) I remember you had very good results in the old days! Currently i am running about 200 mA on 6480.00000 Hz, on request of DF6NM. Also i know that DJ8WX is listening and others too.  Linux/wine, does it mean you are using SpecLab on Linux? If so, does it work well? OK about EbNaut, exciting to see there are more RX stations. Maybe EA5DOM will leave a signal from the other direction in some time ;-) 73, GL, Stefan Am 06.05.2016 23:30, schrieb Michel Brunel:

Hello Stefan,

Now running the 40 µHz test under Linux/wine ...
Antenna is a 10 meter vertical (no loop yet, too noisy at home)

Hope to be ready for EbNaut in a few days.

Hello Markus, VLF,  OK so i will run the next carrier on 6480 Hz for some hours this evening for you and Uwe. Prepare your receivers to 47 uHz (or 63 uHz maybe). 73, Stefan
