I bought the Hurricane AM Modulator. Here in my living room the hum was considerable even though I had an EARTH connection. So what I did was use a coax cable made of two different ends of coax cable, just the isolated kernel of both taped close together so the signal is transmitted on one, received on the other without the wires touching. One end in the antenna OUT of the transmitter, the other end in antenna IN of the receiver. Now I can wirelessly send music from my laptop or telephone to the Hurricane and ‘receive’ it on the radio of my preference. A little hum remains... PS: I later used the INC button on the front to increase frequency to 2016 kHz and now there is no hum or other noise audible on my setup.

Antenna bought at https://a.aliexpress.com/_EHGugUd See also: https://swling.com/blog/2023/06/frans-checks-out-the-mra-qrp-20w-qrp-passive-loop-antenna/?swcfpc=1 On arrival one of the parts, the semi-transparant box with variable capacitor for antenna tuning turned out to be broken due to the bigger box having been thrown around in transit. The seller promptly provided me with the necessary part (plus extra) for repairs. Yesterday I repaired it and today I assembled the antenna and tested it a bit in the afternoon and early evening as soon as reception started to get well enough. It’s a fun antenna, affordable too. The video shows how effective the variable capacitor is.
