The 6N2 should have a quiet receiver. Its MDS specification is 10 dB
poorer than a rice box on 2m and 2m rice boxes are at least 10 dB poorer
than 2m atmospheric noise in mid USA and more than 10 dB poorer than the
2m receiver state of the art for sensitivity. Of course that makes it
easier to stand strong signals, and adding external broadly tuned
preamps makes it a whole lot more susceptible to out of band strong
signals like pagers and repeaters.
