Re: [Elecraft] [K2] K2/100 RF power indication not working - Blown D16 & D17?

[Bill Coleman]

Took me over week to check this, but power is the same whether Tune or 
Tune/Display — 100 watts! 

So, the suspects are likely D16 & D17.

Fortunately, the last time I replaced them I put in a couple of pins from a 
machined pin socket, so it should be an easy job.

I’ve had to replace U6 before as well. I think I have a socket there, too.

[Elecraft] Turning on a KX3 remotely

On the KX3 you can turn on the radio remotely.  The instructions are on p28 of 
the manual and say
"To turn the KX3 on, a remote-control system can place 8 to 12 volts DC on the 
mic jack’s PTT line for 100 ms or longer.”

I use my KX3 remotely two floors up via a Raspberry Pi where  I can either run 
digital programs WsJTX or JT8CALL on and operate remotely via VNC, or I use 
“ser2net” and run Pignology KX3UI or similar.   I haven’t yet cracked send 
sound over the internet as I mainly use JS8call.  Of course PSK31 would be even 
easier

I set the timeout on the KX3 fairly low, so that if something goes wrong the 
KX3 will automatically shutdown and can be restarted.

[Elecraft] KX-2 Accessory Port

[mike.crownover]

My ACC port on my KX-2 has quit working. I can no longer connect to the KX2
Utility. I've tried everything, different cable(s), different computers, yes
I matched baud rates and I've tried each speed. Something is amiss in the
ACC port. Has anyone had the same problem? Is this a common problem? Is
there a simple fix? Will it need to go to the hospital to get fixed?

 

Thanks in advance,

 

Mike AD5A

Re: [Elecraft] [K2] WSJTX -W10 Rig Control Error - PROBLEM SOLVED

[Neil Zampella]

FWIW ... I use DXLab's DX Commander with my K2, and have full CAT
control.  Not using a Rigblaster, but connecting through the RS-232
cable, CAT works fine.   I've worked a DXPedition using this setup, and
the Fox/Hound mode worked perfectly.

I wish to thank all the folks here who offered helpful comments on the

I've been there, but with no resolution this time.  Neil did relate his
solution to the problem and I will respectfully continue with him
off-line as to the details.

The solution was so simple that it hit me in the face when I tried it!

In WSJTX Configuration (F2) Radio tab -  I set Rig to "None".  This turns
off CAT control.  Then I set PTT to RTS and the COM Port to the one that
controls the RigBlaster that is connected to the K2.

Lo and behold, the rig is recognized and operation is as expected.
Sure, there are no CAT control bells-and-whistles, but the program works
KISS.  Now to make contacts again.

[Elecraft] K3s apparent TX failure

[eric norris via Elecraft]

The transmitter of my K3s appears to have suddenly failed.  There is no power 
out.  I reloaded the current fw three times.  I ran TX gain calibration three 
times, and get "tx gain calibration failed because transmit power did not reach 
the expected value.  5 watt calibration failed."  This was at 1.9 MHz, the 
first band tested.  "Calibration power settled at 0.0 watts."
There is no power at either antenna port.
Any ideas?
Thanks and 73, Eric WD6DBM
