Sorry, Erik, I was definitely referring to the DSP NB, not the NR.
Please give the NB a try, at a setting of t1-4 to t1-5. This should
have no impact on normal background noise or signals, but it may
substantially remove tuning noise, assuming you have any above the
noise with an antenna connected.
