OK, seem to have solved the problem. The P3 XV Gain #1 setting was way wrong, in fact never set right. Also had to switch the P3 XV Invert #1 to inverted. So now appears that I can see the 2m spectrum with the P3. Just have to go get a signal generator to calibrate the display.
Alan and Gary from Elecraft kept suggesting what to do until I got it right. Thanks Alan and Gary and Elecraft. 73, tom n4zpt On 8/7/2011 2:02 PM, Tom Azlin N4ZPT wrote: > Thanks Alan, > > I will go back in and check the initial set up for the K144XV as well as > the P3 and K3.
