This is one of those things that has always been possible in radios that had both. In the MP, with the 0-6-12-18 ATT and both IPO and menu selected preamp function, it has always been possible to do preamp with the ATT set. Make any sense? Maybe, but don't think so. Even less so on a K3
A lot of the design decisions in the K3 appear to have been made with an eye to keeping the APPEARANCE of analog function, e.g. so called RF gain. The menu driven RF gain on the Orion was always a startup learning issue. I'm sure Wayne was watching. It certainly is possible in firmware to not allow the PRE to be set when the ATT is on. But why put up with the support calls about can't turn on PRE when it doesn't behave like predecessor radios, when most will intuitively understand that ATT+PRE equals neither. Most of the time I don't need to be protected from myself. The other times no one can help me anyway. : >) 73, Guy.
