LF,
 
I have had permission to transmit on VLF this coming weekend:= 12th and=20 13th February.
Weather permitting I shall try again with my balloon-launched= aerial,=20 hopefully about 50m vertical.
 
The frequency will be
 
8.976 66 kHz  (i.e. 10.000 MHz / 1114) an= d is=20 derived from an oven controlled xtal oscillator.
Hopefully the frequency will be more stable than last time.
If this frequency proves unsuitable I can transmit on 10.000 MH= Z / 1112 .=20 .10.000 MHz / 1116  etc.
 
I shall send a continuous carrier as and when conditions permit= .
 
My newly built VLF TX is working well and can deliver about 150= watts of=20 RF.
On this occasion I shall be using the original (fairly lossy)= loading=20 coil but am presently making a more efficient one.
 
All reports will be most welcome.
