Bill, Alan may provide a better answer, but are you making that comparison on the amplitude of a single signal that is substantially greater than the ambient noise level?
If you are comparing the ambient noise level, the s-meter reading on the K3 will vary by bandwidth, and will be lower at narrow bandwidths - because the total noise depends on the bandwidth. For the P3, the bandwidth of each sample is quite narrow, and the noise level will be lower than shown on the K3. The same phenomenon applies to a SSB signal, but to a lesser extent than noise. The K3 is looking at the entire SSB signal where the P3 is looking at smaller slices of the frequency spectrum contained in the signal. Bottom line, compare the two at a CW signal peak and they should agree more closely. It is just the way the math works out. 73, Don W3FPR On 1/15/2011 11:16 PM, bill wade, sr. wrote: > Newly installed P3.
