Low performance receivers degrade satellite operating practices
A strong case has been made that: A GOOD receiver is needed to hear others to avoid walking on others.
Many VHF/UHF radios have poor receive sensitivity which is also poorly specified. A more expensive receiver may or may not have substantially better sensitivity.
A GOOD low noise preamplifier will overcome poor receive sensitivity for almost any receiver.

Excellent advice and I have posted multiple times on this list how to evaluate your receiver performance using no test equipment, other than a 50 ohm resistor. 73, N0AN Hasan
