Re: [Elecraft] K4 NR & NB

2020-05-23 Thread Brian Hunt
Will the NR "mixed mode" (NRmF5-x and above) where some of the 
unprocessed signal is mixed with the processed signal be available on 
the K4 as it is on the K3?  I've discovered that feature coupled with 
the APF is an excellent way of copying near-the-noise CW signals.


Thanks & 73,
Brian, K0DTJ

Hi Drew,

The K4 has one linear control range of 0-15 for both NR and NB, making
adjustment far simpler. There's virtually no delay in setting up NR.
