I may be out of my realm. Good reading in the link though.
5G is years out there in my area. But I do have a 5G phone. I have to drive to a city 40 miles away to even get a 5G signal.
As in my reply above. Twice a year I have to tweak the declination on my dish to get 131W. 127W has strong TP's across the board. A dB here or there is the difference between signal lock or not. Especially DVB-S2. Agree?
If you sweep your LNBF with an SDR I'm pretty sure you won't need 6GHz capability because you're only going to be sniffing the I.F in the range of 950-1450MHz.....or something like that. Something as simple as a piece of coax jumper opened up and a small decoupling capacitor soldered to the center conductor and insulated from the shield and a bit of soldering to connect the SDR should work just fine. Anyways. I'm pretty sure your everyday run of the mill SDR dongle only goes up to around 1.75GHz without running the harmonics firmware hack. And isn't SDR# only opened up to 2GHz?
I dunno. I use HDSDR and SDR Console.
Anyways. Has 5G cell interference been ruled out? And if your phone is 5G capable are you even getting a signal at the dish? There are tower and info apps to let you know. Or as in my case. Did the earth just tilt a little bit when the leaves started popping out and the snow melted? How about a sacrificial roll of foil folded over in half and wrapped around the dish rim as a test?
