[HamWAN PSDR] Has something changed, or did my Mikrotik lose 5 ghz

[Nigel Vander Houwen]

Mark,

If you were previously seeing signals in the -91 sort of range, you were on the hairy edge of seeing anything at all. Below around -90 you’re unlikely to see anything or get any sort of connection. If you do, you’re lucky.

The weather and many other things impact the signal a bit. We usually see winter signals be a couple dB higher than summer.

So, I think it’s entirely likely that if you were previously seeing signals down that low, that the conditions are just a little different and there’s not enough there.
