Here's my view on your question John.

Argosy - The Argosy, at least the later Argosy and all Argosy II's have a great 
noise blanker 
from my experience.  Had terrible power line noise for several years and during 
that time my 
favorite rigs were the Argosy and the Triton IV.  Of course the Triton is out 
because it does 
not have any WARC bands and the Argosy has only 30 meters.  The down side of 
the Argosy 
is the lack of RF gain control.   There is a mod to install one.  I got around 
it by putting a 18db 
attenuator in line between the t/r switching circuit and the RF board.  
Switched it in and out 
with the push pull power switch on the volume control.

Early Corsair - I'm not sure about the original Corsair as I only had (and 
still have) a C II.  As I 
recall, when first got my C II, an early serial number unit, it had a very good 
noise blanker.  
However, at that time we had trouble with the Russian Woodpecker radar pulses 
conventional noise blankers were not very effective.  Ten-Tec sent an upgraded 
blanker board to registered owners of the C II of which I was one.  I swapped 
boards and the 
new one worked better with the woodpecker.  BUT it did not work very well on 
other noise.  

This all from memory so take it for what it's worth.   Anyone else get the 
upgrade noise 
blanker board from TT?  Please jump in and give us your experience.
