Fred, You are pulling what I call a "boogie man" ref the RFI. It gets addressed at the design stage.
Your fans and heatsink comments are also not valid. Power is NOT dissipated in an evenly distributed manner. Again, it is an issue addressed at the design stage. You comment about service is valid, but, the goal is to never need the service. I have had no issues with the Kenwood service, my TS-480 just works. OTOH, I put the TS-480 back into service when my K3 was sent back to the factory.

Too many for discussion here. However two thoughts. In general the faster the processor the 'more' chances of producing RFI. It could be Wayne and the boys kept the processor speed low to reduce noise. Also in CMOS processors the current drain goes up proportional to the square of clock frequency. Simply faster processors take more power and with power comes the need for fans and heatsinks. That's from the physical side. However the application of more filters could possibly reduce noise from the software side but this is far from a simple tradeoff. Finally even if were a push between the K3 and 7851 have you ever heard of anyone bragging about their service? 73 Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Robert Sands Sent: Monday, November 9, 2015 1:32 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 DSP processor speed I was informed by an ICOM 7851 owner that the ICOM has DSP processors are 10 times as fast as the K3 and therefore has noise reducing advantage. Not that important to me but curious if this is meaningful and if there is consideration of chasing this performance spec by Elecraft and if not Why not?
