I've received several transmissions from SAQ over the years with my Rycom selective level meter and a longwire.  Interesting audio signature there.

Always thought that thing was more mechanical then electronic. Huge generators and transformers. Wonder when the first Short Wave transatlantic station went on the air?  looking at what the state of the art was in 1925 to all the huge changes that took place by 1935 have to think maybe that was the biggest decade of change ever from long wave mechanical, spark gap, short wave and finally AM Broadcasting. Lot of change in just ten years.

A learned about the Christmas Eve morning transmissions a few years ago and tried several antenna matching configurations to optimize what I had for 17.2 kHz, which is quite a stretch for even a 160m antenna.

It finally occurred to be that I might be approaching things from the wrong perspective. On any other day, 17.2 kHz would be thought of as a frequency within the audio range. Thinking waaay out of the box, I fetched some audio transformers and started coupling the antenna to an RSP1A SDR as if it had an audio input.

Amazing. The few signals in that part of the band jumped in strength significantly. NAA at 24kHz in Maine was now booming in, although they also run a strapping 1.8 *million* Watts.

While most of the transformers worked quite well and had the additional benefit of virtually eliminating BCB interference, the best "match" occurred using a Radio Shack 1k to 8 Ohm audio transformer.
