Hi David Thats what I am referring too, its the tuning by product effect. Now if there is weak signal on that spot, it makes it very difficult to copy or tune in a station. It is as if the signal "drops into a hole" or that the synthesizer skips or jumps that spot. Thats the best description I can give. Anyway you have to tune carefully.
On bands where there are a lot of birdies that have been removed, if you spin the VFO fast you can notice the "holes" 12 Meters is a case in point, there are several birdies there, and the band slice is small. You notice the tuning weirdness more on a narrow band like 12 meters. You also have the pre-amp engaged and the noise floor is low, any quirks on receive become very obvious. Holes or artifacts same difference! Anyway its a quirk of the radio and thats it, I can live with it! 73 Juergen --- On Mon, 6/13/11, David Gilbert <[email protected]> wrote: > From: David Gilbert <[email protected]> > Subject: Re: [Elecraft] P3 Broad Birdie & straw men... > To: [email protected] > Date: Monday, June 13, 2011, 2:29 PM > > Juergen, how exactly does the SIG RMV feature in the K3 > "leave holes in > the band"??
