As far as I can tell from a web search that might be a SR400AC (giving us the FCC ID: might help to check that).
If it is that model, it's input is marked as 12V 3A which should give decent range of PSU's to test.
If a clip on or two didn't do anything then larger FT-240 with multiple turns should show if it is coming from the leads.

Personally I like a low power main router, something decent that sips electricity as it is harder to spray energy around if it is hardly using any, then get a separate WAP (or mesh?) and move those around as best suits your location and wireless coverage. One other option is to move that router away from the incoming data and bridge that gap with fibre to ethernet adapters. In the UK VDSL is ubiquitous and noisy, I have the VDSL-Ethernet modem then Eth-fibre-fibre from there, means the VDSL lead is kept short (with ferrite) and the rest of the stuff has no "long-copper" links to risk radiating (or injecting noise).

(I'm going to have to put a personal web page up somewhere to avoid posting the same "fibre, ferrite.." comments on all threads, at least I didn't mention a brand of routers this time.)

One for Rob (no follow up needed),
Checking my Grafana plots, 40m together with 60m were virtually a straight line, all the others looked normal.

Long story short I had a -1000dBm/1Hz recorded at the same time on those two bands so the "Auto" scale was doing it's best to keep everything in view.
1:36AM was the exact moment we had a fairly local, singular, lightning discharge.
I am somewhat impressed that it caught it, equally disturbed that all my Kit was connected to the antennas at the time.

Hi Tom,
Quite interesting idea to have a "follow" feature, would probably need the users permission (or a pop up "user x wants to follow") or it gets a bit creepy.
Yeah, "stalker mode enabled...".

I've seen people on my SDR and wondered what they were looking for.

Project needs a "Thermal Cape"
I've ordered some bits as my scrap box only has a couple of heat pipes and both need a lot of work, would get round the space issue though.
This is just waiting for some themally conductive double sided tape plus a pad for the PMIC and a bit more inspiration on physically retaining at the network end.

The ML-30 has an impedance mismatch that means there is a noise spike around 5MHz with the supplied loop, DSL creates loads around 15MHz so phone lines are an issue.
That said for a balcony install your noise level is better than many. I don't think mine 7m from the house had that few interfering signals.

I would try another BiasTee - feed the voltage to the loop through that. The supplied BiasTee has a 5V-12V step up which does create noise. I used mine with an unregulated "6v 600ma" Linear from a DECT phone, that gives about 10V at the load presented by the ML-30. You could see a bit more noise generally but also some wanted signals may come up throught the noise.

Also buy Ferrite beads, large sizes (11-13mm) wind all your in-home cables through those a few times while watching the waterfall. I did that unitl I could not longer see a difference.
Concentrate on VDSL/ADSL lines and any switchmode supplies.

I aslo found that a large FT240 size ring on the coax (as many turns as possible) realy helped, they are expensive but really do sink the QRM.
