Hi Dave, My K3 shows an IMDR3 of between 110dB and 105dB with slight variations from the upper to lower side. This with the 400Hz roofing filter and 400Hz DSP filter at spacings of 100, 50, 20, 15, 10, 5 and 2kHz on the 20m band. Last week our quick and dirty first look also gave us numbers in the same ballpark: IMDR3 of 106db at 20 and 5kHz and 104db at a spacing of 2kHz. We did find some spurs, last week, which were coming from one of the HP signal generators, which slightly confused us at first. The spurs were very far down, but they were there. vy 73 de toby _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
