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.

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

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
« on: July 24, 2020, 1542 UTC »
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.

« 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.
