Chip sounds on 6925
« on: February 09, 2014, 2246 UTC »
Notice it more this evening..Can anyone guess at what I might be hearing. It sounds like a short swoosh chirp that pulsates every 2 sec and sounds like tone gets higher and higher? SSB then disapears... Maybe some occilation on this end local?  Sounds like if you had a carrier and then nturned the tuning knob fast?

FWIW, I've heard switching power supplies make similar noises, especially phone chargers on standby.
