Hi VLF

 

May be too late L

 

I have just started FFT recording with SLab

VLF,

My new VLF coil is now in operation. It is designed to run 300 mA. The firs= t station where i like to transmit some messages is 8270 Hz, just because 3= 6 km it is the easiest band on the VLF frequencies available for us. The id= ea is to transmit at least 100 hours on each band down towards DC, just to proof the design.
Does someone like to join the experiments, RX or TX wise?

I'm going to start a first transmission tomorrow morning using EbNaut:

f =3D 8270.005000 Hz
Start time: 22.September.2017  06:00:00 UTC
Symbol period: 24 s
Characters: 12
CRC bits: 16
Coding 16K21A
Duration: 11h,31min,12sec
Antenna current: 300 mA


73, Stefan
