[Kenwood] Re: TS-570

[Dave Holford]

I have to comment on this since I have recently had the opportunity 
to do a side by side comparison; although my experience may be 
at variance to some other contributors.

My TS-430S and R-5000, which I have had for several years, both 
have excellent noise blankers. They both totally eliminate ignition 
and electric fence noise (the electric fence runs within 20 feet of 
my HF antennas). They even almost completely eliminate the 
LORAN-C pulses on 100kHz.

I recently acquired a used TS-450SAT and a new TS-570D. The 
noise blankers of these rigs do not even come close to the older  
rigs and are a real dissapointment. Otherwise they are both fine 
rigs. 

While I am at it I have one other comment and that is the lack of a 
manual notch filter on the TS-570. The automatic one is fine, but it 
cannot handle an interfering CW signal which the manual ones can 
take out with ease.

If anyone has any modifications or suggestions to improve the 
noise blankers on the TS-450 and/or TS-570 I would really like to 
have that information.
