[TenTec] Drake R4-B Sensitivity

[Ken Brown]

Bill,

Hopefully you mean uV and not mV if you are talking about receiver 
sensitivity. Even so, increasing sensitivity from 0.5 uV to 0.1 uV will 
probably only help on the higher HF bands, or when using inefficient (rx 
only) antennas. On the lower HF bands and MF, noise levels are generally 
so high that 0.5 uV sensitivity is enough.
