Topband: topband for k3 users

Sat Oct 5 13:43:37 EDT 2013

Jose,

Not trying to compare or talk down the very fine K3, I am only giving you my 
real-world experience.

In regards to your inquire; I cannot speak of the AM broadcast issue, 
however regarding "city noise"...My Kenwood TS-590 performs true magic by 
means of use of the noise reduction control!. NR1 is a analog type with NR2 
a DSP type.
Living in a suburb of Cleveland Ohio in a populated city lot-with 
power,telephone & cable lines across my lot, the Kenwood TS-590's noise 
reduction is almost unbelievable. Compared to my TS-440, TS-450, TS-511, 
TS-850 & TS-930 Kenwood sure got this function performing beyond what I ever 
experienced in an HF transceiver!

With the usual "noise" we city dwellers experience by use of the noise 
reduction function-the noise is "completely" gone and leaves nothing but the 
pure CW tone-almost in an eerie manner. Only thing I can compare it to was 
my TenTec Century-22's well known filter system- You hear nothing but the 
station desired and absolutely nothing else...No white noise no atmospheric 
noise no nothing.

Please know I am not comparing the TS-590 vs the K3, wont even get into all 
that and there are other user groups available for that conversation...I am 
only offering my reply & experience to your inquire of  improved reception 
with "city type noise".

Good luck with whatever you decide...There is a solution to your 
situation.....
