Noise on 27.395 Hz

[CT4013]

Whilst trying to listen on last nights net (26th Feb) I had noise bars on the scope at 700Hz spacing.
Just after 10pm the bars slowly moved & I could actually hear a couple of people, it was still noisy though.
About 11pm the noise bars drifted back up & I gave up.
I hope it's not the solar panels that were installed last week, so I will listen on the frequency over the coming nights!

Take a look a these. . . . . all have interference, but none of them move up or down the band

Thanks Ray, you have certainly done your homework.
I will go through them after the 10M Test Net.

ps. I tuned to 27.395MHz last night & there was no sign of the dreaded bars.

I don't see the diagonal lines on the video waterfalls that I had so undecided.
I checked 27.395MHz again yesterday evening and no noise again!
My plan is to check each evening until/if it happens again. It has to be someone near me as I always have the same power bricks/supplies on whenever I'm on radio, Also 'Station Manager' always has the same for the LED lighting etc.
