A VLF transmission on 14.2 kHZ
For those who ,like to try and receive the SAQ transmissions here is another VLF transmission which would like reception reports, this time from a balloon aerial on 14.2 kHz

Re: A VLF transmission on 14.2 kHZ
Funnily enough I've just been talking with a friend about this. I usually hear the SAQ transmissions OK on my homebrew LF loop and SDRPlay receiver, so I'm hoping the loop will work just a few kc/s lower. I don't think there's been any mention of the power level - obviously it will be a whole lot lower than the mighty Alexanderson beast!

Re: A VLF transmission on 14.2 kHZ
Hi
Having had another look at the Alexander page, I think it will be very low power. I had thought it was the antenna that the balloon was taking up, but the mention that it will rise to 30km (around the normal bursting point for a High Altitude Balloon) suggests a battery powered transmitter with a trailing antenna. Still, you never know, it will be very interesting to see the results Kind regards Dave G0ELJ |

No reception here. I've been listening since 1200 hrs and not heard a sausage.

I will be sending a "no signal received" report to them. Too much noise here.
