I noticed a few  weeks ago that someone was using TDoA while listening to my transmission. I wonder how accurate it was?
Yesterday I tried it to located a HF  transmitter which I already know the location of and found it To be hopelessly inaccurate. Skywave wouldn't have helped.

1927 Music. 80's pop?
Weak but very audible.
1950 Michael Franks, I think.

1915 trace of music. Too weak to ID then gone.

That will be fine on SW but on MW (Txing), the SW feedline running close to the tower may cause an issue with tuning.

if you took time to read what i said i didn't say we were closed down our link to the tx got closed down our aerial was down our web site got closed down fact .I t was nothing to do with short wave I said we will be off air for a break as we didn't know what was going on .our aerial is now back up.We went off air for security reason ,and no link to our tx

stated Paul Watt.

One thing we can all agree on is that Brian is Brain(y)

Very good Jock. I didn't cop that  :D

Very wide 12 Khz audio today

Sounds like Ofcom had nothing to do with it, this time.

It's just a load of attention seeking drama. He's been posting on every message board about being closed down.

Nothing to see here!

Equipment / Re: DRM pirates

I used the DReaM software to generate DRM about 16 or 17 years ago. I had to modify my high level audio MW transmitter in some way to take the coded signal. Can't recall exactly what I had to do but there were 2 outputs from the PC. One output went into the normal audio input on the TX and the other went to a small circuit that I had to put in the output of the PLL oscillator.
I don't think the mod is needed on modern transmitters though.

It worked.............sort of.  Not having a portable DRM radio was not ideal for field tests but I was able to decode it on another PC in the house with a modified radio.

Equipment / Re: 20mb and 10/11mb folded dipole antennas
« on: July 16, 2020, 1558 UTC »
Just going by my experience of folded dipoles on band 2 VHF, I would say that the bandwidth is considerably better. I've been toying with the idea of making one for HF transmission but I'm not sure if I can build one to handle the power I would be using.
