Sometimes people ask what I prefer, receivers with more bandwidth or better quality?

I did a few tests on VHF UHF with a professional receiver (1 MHz bw) against a cheap device (4 MHz bw) at the same location and with the same antenna.
Result :

• 1 MHz high quality: 2773 decoded signals
• 4 MHz, low cost: 5671 decoded signals

4 MHz, low cost SDR

1 MHz, prof. SDR
