P3: Noisy on 28MHz

[paul.bradbeer2]

I've been somewhat curious as to why my P3 has been showing an increased
noise floor on 28MHz recently (only 28 MHz, all other bands are fine..).
To cut a long story (but quite a methodical investigation) short, powering
the P3 from my K3 gives about a 10dB increase in noise compared to powering
it direct from my RigRunner.  All adds up....my P3 always was powered
direct until I did the mod on the K3 to increase the available current on
the 12v accessory socket.  It's no hardship - I'll just power it from the
RigRunner but curious to se if anyone else has noticed this?
