Yes, that would be great. The K3 doesn't do that, unfortunately.
The K2 and my other non-Elecraft rigs don't have the 'presence' that the 
K3 gets from the ability to insert a slight delay on one side.

[Elecraft] Elecraft CW Net Report

2021-12-26 Thread kevin


Good Evening,

   Conditions were so-so to OK.  Rapid QSB was on everyone, it chopped 
up weaker stations, the stronger ones were better.  More than one 
operator mentioned I was the only station on the band.  I did not hear 
anything except check ins on either band.  I don't think it was due to 
lack of focus.  However, an hour with a chainsaw followed by working 
with cold hands did affect my sending.  It took a word or too for my 
fingers to lubricate.


   During the second check in on the second net I watched a large tree 
bend over and then fall over.  It rotated around its root ball like it 
was a ball socket.  It fell in one of my antenna paths.  If the antenna 
had not already been broken it would have fallen today.  I was also 
taking each second as it came because the power kept blinking.  If there 
is any wind tonight there will be a power outage.  For some reason this 
layer of snow is not sloughing off of the trees.  Power lines don't like 
it either.



  On 14050.5 kHz at 2300z:

NO8V - John - MI

W0CZ - Ken - ND

K4JPN - Steve - GA

K6XK - Roy - IA

AB9V - Mike - IN

W8OV - Dave - TX


  On 7047.5 kHz at 0030z:

W0CZ - Ken - ND

K6DGW - Skip - NV

KG7V - Marv - WA

K0DTJ - Brian - CA

K6PJV - Dale - CA

AE6JV - Bill - NH



   Until next week 73,

      Kevin.  KD5ONS

Re: [Elecraft] KAT 500 Firmware

2021-12-26 Thread Dave New

I had a KAT500 fail to xmit back to the PC, but it could receive, so  
only one of the transistors was out.


To determine this, use Putty or other terminal program to send test  
commands to the serial port that shows up when you plug in the USB  
cable.  If you can command the KAT500 to switch antennas, for example,  
but you see no return message when you ask for the firmware version,  
then you will only need to replace the transistor that drives the  
KAT500 to PC line.


73,

-- Dave, N8SBE

Quoting Andy Durbin :

"I had this happen a while back and it turned out the Q! and Q2  
(transistors that control the send and receive lines on the com  
port) were in operatable."


I would expect that fault to result in the utility not seeing any  
data at all.   In that condition the utility does not report that  
the connected device is not a KAT500 because it can't connect at all.


Please confirm that you saw the message "Unexpected Device -  
Connected device does not appear to be an Elecraft KAT500" when the  
TX and RX data lines had both failed.  In my experience this fault  
can only result if the utility is connected to a port that is  
receiving data but it's not the data the utility was requesting.


Andy, k3wyc
