I post this more as a public service than a great DX catch: If you hear South Asian music on 580 kHz, it's from Edmonton/Beaumont, Alberta. It just signed on full-time about two months ago, so it's hard to find in many of the online AM listings.
Behind the mix of KIDO’s “Coast to Coast AM” and sports talk on Southern Oregon's KTMT the other night, I could distinctly hear South Asian music. After some online hunting, I found CHAH’s “MyRadio” site, and the online stream matched. I also matched what I was hearing with an SDR near Edmonton.
CHAH is listed as 10 kW; distance from me is 530 miles.
