Hi All,

I have been reading the reports on the K3 noise blanking 
abilities.Unfortunately there is no audible comparison between the 
jamming signals on 160 meters and the signals both on 40 and 80 
meters.They appear to be more a rapid pulse signal where the 160 meter 
is a continuous noise with an overriding pulsing which I originally 
described as sounding much like an idling diesel engine.
The "Dragon" interference really needs to be examined closer to the 
source on all three bands to determine the nature of the signal and also 
perhaps a K3 can also be tested the same way to see how the blanking 
system really works if at all on these signals.
I find I can handle the 40 meter pulses fairly well with my existing 
equipment,most of which is fairly old.However nothing I have has any 
effect on the 160 meter jamming signal which can reach S7 to S9 at my 
location at times.
I would be interested in any follow up of this problem and actual field 
tests on 160 meters with the K3.Not that I will be ever able to afford 
to buy one..

Good Dxing......Bob VK3ZL...
