Hi Chris,

Very good luck. I'll be looking for you and hoping for success this time.

An email direct and to this group saying when TX starts/ends would be helpful. Don't suppose you can send QRSS60 or similar to help with ID? Have passed the word on to Nick G4IKZ as he is closer to you than me and not sure he subscribes to this list.

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.
