I hope to receive the SAQ station at 17.2KHz, using my RSP2 High-Z antenna input. So not using the Mini-Whip of PA0RDT.
Has anyone experiments doing this ? What type antenna is used.

For most of my LW/MW and HF listening I use a Wellbrook 1530 loop to help keep the noise down, as wires are very noisy in an urban environment. However, the 1530 falls off below 30 kHz and only just receives SAQ, so I built a similar loop using a plastic hula hoop with a few turns of wire inside and a simple amplifier similar to the PA1m design. I put a large capacitor across the loop to limit its response to below 100 kHz. Result! SAQ is now easy.

Thanks for your quick answer.
The good news is that I live on a very rural area with neighbors a mile away.
For the homemade hula hoop you used an preamp, why can this not directly connected to the High-Z differential input from the RSP2 ?
Do you remember how many turn you used for this magnetic antenna ?
Good suggestion for the large cap !

Please explain what SAQ is about? Thanks

It a machine transmitter in Sweden on 17.2 KHz

PA0MHE. Me again. OK, I've just found a few notes I made when I was building this LF loop. The hula-hoop is about 80cm diameter and there are six turns of wire threaded through the tube. This gives 125 uH and to tune it to 20 kHz took (get this) 470 nanofarads or 0.47 uF. Tweaking this value could land you directly on SAQ, but mine receives it anyway even though it's not bang on the frequency.
Re using it without an amplifier - I've just quickly built an identical loop and connecting the ends to a balanced, twisted feeder and applying the other end of the feeder to the balanced hi-z input of the RSP2 got me signals. About 15dB lower than the version with the amplifier but I'm sure it would be OK.
I'll be taking my loops down for their annual maintenance soon, so I may add an extra cap to see what's even lower down!

Here is SAQ as received on the loop this morning with my RSP-2. Lots of electrical spikes today, but copy is still good.

Thanks, I also succeeded to receive it magnetically with to your help.
