Have I just been unlucky and got a bad unit, or does everyone suffer spurious signals on their TinySA?
I see specific signals at 144.20MHz, 192.15MHz, and 240.19MHz.
They are unstable, and wander over a few hundred kHz, during a period of about an hour. Each are 12-15dB above noise floor in 10kHz RBW.
They are definitely internally generated. I have applied 50Ohm loads to the SMA connectors, and even operated the device inside a Faraday cage, but still the spurious signals remain visible.
Any feedback welcome.
John
