I'm hearing an uptick of dead air baby monitors. Don't hear any babies or people talking. Just a carrier. If I listen real close, I might hear outside noises. On one I can hear a train blowing at the same time I can hear it out the window.Off topic:
I'm hearing a baby monitor on 49.830 MHz FM; probably within a few blocks of me.
I'll have to get my 5ch 49MHz RS walkie out and see if I can find it.
Someone in the Lowe's said he uses a baby monitor to listen to his garage during the night. Might be what I'm hearing.
