Re: SAQ Grimeton Transmission on July 4th
Kellymarie, I took a look for the pips and there they were on 175 kc/s as you said. Attached is a waterfall of them. I couldn't get a reliable null on my loop antenna so it's either coming in on skywave or it's something on the mains wiring and coming from all directions.
