[Fourlanders] Question on Receiver Sensitivity

[S Kosmetatos]

I'm looking at the specs on my two all-mode radios, the ICOM 706 and the
Yaesu FT-847. What are the receiver sensitivity figures which would indicate
the need for an external preamp? Are the figures shown adequate for the
general WS communications I would be working, or would I benefit from
preamps?

I'm thinking if I do, I want to incorporate them as mast mounted as I
assemble the components for my antennas and tower.


		Icom		Yaesu
 50 MHz	.15 uv	.20 uv
144 MHz	.11 uv	.125 uv
430 MHz	.11 uv	.125 uv

Both are based on 10 dB S/N in the specs.
