LF,
I have had permission to transmit on VLF this coming weekend: 12th and 13th February.
Weather permitting I shall try again with my balloon-launched aerial, hopefully about 50m vertical.
The frequency will be
8.976 66 kHz (i.e. 10.000 MHz / 1114) and is 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 MHZ / 1112 . .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 RF.
On this occasion I shall be using the original (fairly lossy) loading coil but am presently making a more efficient one.
All reports will be most welcome.
