[Amps] FCC Denies Expert Linears' Request for Waiver of 15 dB Rule

[Jim Brown]

Hi Fern,

The best real world test is that the noise level should rise by 8-10 dB 
when you connect an antenna to the radio. If it doesn't, your ability to 
receive weak signals is limited by internal noise of the radio. 
Obviously, this very practical test is location specific. But if you 
live in a quiet QTH, noise performance of the front end becomes 
increasingly important.
