If you take a look at the block diagram, you will see that the Hi-z antenna goes in at a much later stage than the A and B ports, bypassing the filters and notches. It's a bit of a mixed bag - it misses out on the filtering and notching, but it's actually a quieter receiver better suited to HF and l...

Wow Phil, commiserations on the eye injury. I hope it recovers soon, but I know how slowly eye injuries go and how painful and irritating they can be. Good luck with it.

I wouldn't worry about it, Paul. It is completely counter-intuitive that the loop should receive best when 'edge-on' to the source. Until you start to analyse what's going on with a loop, that is. Then you get one of those 'Ah!' moments and you never look back. Sounds like your Wellbrook is working ...

Me again, sorry.
Don't forget the main responses of the Wellbrook are 'off the edges', with a hole going through the centre of the loop.

The latest versions of SDR# will not work with SDRPlay products as the writers of the software have deliberately prevented it.

Which software is this? SDRUno 1.22 won't accept it as it is above the top limit of the tuning.

Hi Max. The original, first-version of Uno was indeed a bit of a pain as all you got on first use was a tiny start-up pane. You had to fiddle about opening the various panes and sliding them into position, then save. After that it would always start as you had saved it. The latest version of Uno ope...

Thanks for going to the trouble to post this Noel, it's all very useful info. Just one point - in a superhet with a 455 KHz IF, the image frequency will be at TWICE 455 KHz above the receiving frequency. This is because the local oscillator will be running at Fsignal + IF and the image response will...

Hi Paul, it's Andy again. I bet you think I'm stalking you! I honestly cannot think of any reason why you should be seeing such poor reception on the Hi-z input from your active antennas, unless you are making a mistake with the connections. The output from the antennas DC power injector box should ...

Hello Henry and welcome to the forum. You'll need a standard USB-A to USB-B lead for the connection from the RSP to your PC and some kind of adapter or adapter lead with an SMA male plug on one end to a female connector which matches your own antenna connector. That's it. It's worthwhile reading all...
