I neaver hear or see any of them. There is no Band who the can run?!Another pain in the neck are these cheap wireless mice, which often run right around 27 Mhz
Sure I use 3 of them but the dont help that much. The other Problem is I have to power the LNA via USB to.A series of clip on RF beads quieted things down quite a bit (as ka3jjz mentions above)
I am not from us. But when I have an training to become an IT Engineer our Instructor told us that no Pc, Laptop, Mobilephone,... could legaly sold in Austria because the dont pass an RF Test in an "independent" Test Lab. Such an Test would take 1 - 2 Years before the could pass and everyone know its impossible to wait that long...If the computer and monitor and other parts are not all FCC Part15 compliant, you may never get rid of the RFI or EMI they emit. And if they are compliant, they may be Class A or Class B compliant. Class A is for "office" use, and is not supposed to be sold for personal/home use, as it will always be excessively noisy.
I dont know it powered with an small Cellphone USB Charger. And yes i tried several out and nothing chance on the noise floor.What does that little Pi3 require in terms of power?
The most USB Charger are the same crapy quality. The only thing who is different is the Name and the Logo.Sometimes getting a more up to date version of the power supply is the answer.
Wow,, I did the roll of coax and my noise floor dropped and so did some of the spurs/spikes...Yes I tried out but nothing. No difference between Metal Shielding or not.
And Ferriets doent bring that much/ anything.
I run ACARSDeco2 1x with and 1x without Ferrite Cores arround the USB.
No realy difference in kb size of the logfile.
