Re: LF: Cat Whiskers

Hi All,

I regularly get that type of visual image on my captures along the line of the harmonic on 504 kHz, example is attached which occurred on the 12th of this month.

I have seen the effect again today fro 1008 to 1140 utc but not as strong.

Too glib

 

I can visualise the whisker pointing in the direction of time but not the mirror image how does that work. Please explain?

How can the spread of sideband frequencies colapse onto the start event before its happened it doesn't compute!

I see similar QRM . centers for me at 180 Kc and will come and go

the interference will be noticed up to 500 Kc. Usually a short carrier happens first

the burst usually lasts for 10 sec. I figure mine is from some kind of switcher

at the hospital / I am right across the street form the hospital

 

be interested to find out what it is
