The wind is too strong to launch the balloons anywhere ne= ar to=20 vertically and the first attempt
snagged a nearby tree.

I'= ll try=20 again later if the wind drops.

I think I'll take up stamp col= lecting as=20 a hobby instead !

The frequency will be

8.976 66 kHz=C2=A0 (i.e. 10.000 MHz / 1114) and is deriv= ed=20 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 /=20 1112 . .10.000 MHz / 1116=C2=A0 etc.
=C2=A0
I shall send a continuous carrier as and when conditions=20 permit.
=C2=A0
My newly built VLF TX is working well and can deliver about 150= watts=20 of RF.
On this occasion I shall be using the original (fairly lossy)= loading=20 coil but am=C2=A0presently making a more efficient one.
