Re: [Elecraft] FW: K3/KPA500/KAT500 SWR problem

2014-12-20 Thread Don Wilhelm
I doubt your problems are because of the firmware, but the answer about 
the best version of firmware to use is to always load the latest 
production version.


Beta versions can be useful if you are experiencing problems that the 
beta release corrects.  Remember that beta versions are usually OK to 
use, but there are made available so a large number of users can report 
any problems they experience.  If there are no problems reported, that 
beta version will be advanced to production status. OTOH, if there are 
problems reported, that beta version will be replaced by another beta 
with those problems addressed.

2013-12-30 Thread Bill W2BLC
In regards to proper grounding etc.: I think it is safe to say that K3 
owners have a very good grasp of what is needed to construct and operate 
a proper station - safety and RF wise.


I do, yet still went back over every last connector/connection/lug, etc. 
Everything is locked down properly here. No baluns, good coax, and 
everything is mechanical and soldered along the entire antenna routes. 
Yet, the problem continues. Perhaps the most disconcerting part is that 
my other auto tuners/rigs do not exhibit this difficulty. Perhaps the 
KAT500 is seeing something the others do not.


The difficult part is never knowing when the tuner will take off and the 
fact that MANUAL selection does not appear to make any difference. I 
have been using MANUAL for a couple of months. I do not see that it has 
made any difference in occurrences. The instances of run-away are 
random and it is usually days between events.

Everything in the shack is grounded to an aluminum bus bar across the 
back of the operating table which is tied with #6 solid copper to the 
same point as the tower and AC Main grounds.


Just for reference, the antenna is a 260ft OCF Inverted Vee at 75 ft 
using a Balun Designs #4115ocf 4:1/Choke combination balun.  Coax shield 
is grounded at the top and bottom of the tower.

Hmmm,  An aluminum bar tied to a copper wire!  Be aware that there will 
be oxidation at the junction point due to dissimilar metals unless 
special bonding is used to slow (but not stop) the oxidation.


Just something to bear in mind.

Good point Don!

That's why I use stainless steel hardware and ICE 602 copper/aluminum
