It's tough to beat the air 910 for receiver sensitivity and noise figure. It uses Gaasfets for the rf amps on both bands.I have two of them at both my primary and secondary qth.They both check at .12 uv on uhf and .11 uv on vhf for 20 db.That is state of the art stuff.If you compare the specs on the ic 910H and the new 9100 on vhf and uhf you will find them to be identical.WB8RJY
