[Elecraft] KAT-500 behavior under firmware 1.58

2014-02-22 Thread DeYoung James 
Greetings,

Here is a little feedback on the new KAT-500 firmware.  I installed version 
1.58 last night and was using my 160m capacitance hat vertical antenna and 
observed what I think is strange behavior.  First, I admit my 160m cap. hat 
vertical is not an optimal antenna.  Previous versions of the firmware however, 
produced acceptable matches.  Version 1.54 was a little better by introducing 
the finer step search.  The version 1.58 firmware however produces worse 
results in my case.


The tuning passes, the clickity-clack search, is clearly different on 160m.  
The KAT-500 now finds no good match in auto mode.  I place the KAT-500 in 
manual mode and using the utility software set previously used capacitance 
and inductance values.  Now the KAT-500 goes sometimes into bypass mode (I have 
no KPA-500), drops setting values with an audible click, and some times when I 
checked the utility it has gone far away in capacitance and inductance values 
without a clickty-clack tuning cycle.  My K3 used to be able to produce 
nearly full power with its super ALC method of power control.  According to my 
Palstar PM2000A power meter, not so much anymore, as it behaves now like 
traditional power fold back on 160m.  It appears something is interacting.


I have no evidence of RF in the shack.

[Elecraft] K3 not completing all events when changing frequency by direct keyboard entry

2013-06-01 Thread DeYoung James 
I do a good amount of direct frequency entry from the keypad.  About 50% of the 
time when I hit the FREQ ENT button, punch in the frequency, and finally hit 
the AFX/[return] button some actions take place but not all.  Most obviously, 
sometimes the relays don't reset to the new settings, the signal bar graph gets 
either stuck w/no signal or is pegged, no audio heard, etc.  It seems to be 
random when it happens and how it hangs.  I try to make sure that I hit the 
AFX/[return] button centrally and with enough contact time to be sure it takes. 
 However, I'm still getting the hangs.  Any ideas how to fix this?

[Elecraft] KTCXO3-1 TCXO warm up time to stabilize

2013-02-03 Thread DeYoung James 
Greetings,
 
I find that 3 hours in 70F room is required to reach stabilized frequency.
