RR Laurence,

Your loop for 137 kHz, what are the dimensions? What type of wire do you 
use? Do you reach 1W with the loop as well? And at which power level and 
antenna current?

73, Stefan

RR abt EbNaut. A short EbNaut message, like a callsign, transmitted in
8K19A should be no problem unless your PC isn't older than 10 years :-)<br>
BTW are you still QRV on 137 kHz, i.e. can you transmit?<br>
I guess that Jay would be able to decode you...<br>
And is your VLF grabber still ready? We have never been successful over
that path, even with the kite experiments. But now i have that earth
loop and it looks like i can reach a similar signal strength, even
stronger! And, with that loop i can transmit at night whereas this was
not possible with the 300m kite. There could be much better chances at
night. Some day it may be worth a try...<br>
