Preamp 1 has negative feedback to improve linearity without compromising NF. In the Pro3, the preamps have been designed for highly linear large-signal handling, consistent with a low noise figure. When switched in, Preamps 1 and 2 do not raise the audible noise level in the receiver as much as they did in the Pro2. S9 + 60 dB signals 1 to 2 kHz above and below our channel edges did not produce any perceptible artefacts in the received audio. In addition, the Pro3's strong-signal behaviour appeared to be excellent.

I am able (by using a combination of NR, NB, Twin PBT and Manual Notch) to squeeze intelligible copy out of the assorted 'garbage' on the band more effectively than on the Pro2.ДЄuthor: Topic: Stolen IC-756 Pro 3 / SP23 /PS125. The next day, I was able to sustain the sked with my friend Matt KK5DR somewhat longer, as the Pro3 'hears' signals buried in the noise somewhat better than the Pro2 did. I find myself routinely operating with the preamp off on the Pro2, I invariably had Preamp 1 on. Overall, I would judge that the S/N ratio is better than on the Pro2, even in the presence of power-line noise.

The NR and NB appear to have been significantly improved. I was able to work a number of SSB stations on 40m which I would not have heard on the Pro2.

Preliminary findings are that it pulls weak, noisy signals out of the noise somewhat better than the Pro2. That evening, I installed the Pro3 in my station.
