Wayne, Eric, Lyle: I checked my DSP firmware. It is 3.16/3.00. The new MCU (2.04p) is supposed to let me turn the NR/Notch on or off by pressing two buttons simultaneously. When I do this, I get 'not inst'. Do I have 'old' DSP firmware? If so, how do I order new DSP firmware (I can't find anything on the website)? -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco
