Re: [Elecraft] K3 s/n 2274 update to new synthesizer board

[JOHN LAWRENCE via Elecraft]

Hi Don
I was thinking of you when making this inquiry.  Thank you!  
I’m also changing K3 to other changes: usb io, plus adding the 2 meter and GPS 
boards aimed at the digital mode use.  
Awaiting last K3 update production boards to arrive in June.  
Again thanks for tip on synthesizer board washers when removing the old board.

John,

Yes, there are lockwashers behind the board - when removing the old 
synth, do not initially remove the screws completely - loosen them until 
they are almost out, then tilt the board toward the rear and push the 
lockwashers up against the old synth board.
Now you can fully remove the screws without dropping the lockwashers 
(they will stay on the screws if you are careful)

[Elecraft] K4 production software release 13 now available

[Wayne Burdick]

K4 production software release 13 is now available. We strongly recommend that 
all K4 owners perform the update to remain current and take advantage of the 
latest improvements. 

An Ethernet connection is required to obtain new software. The K4 accesses our 
software server directly.

To perform the update:

1. Tap the Fn button (on the LCD), then hold UPDATE

2. Select "Production Release" from the pull-down menu at the top of the 
screen. Then tap the "Check for Updates" button. This will download (but not 
install) the latest files.

Note: You can tap "Release Notes" to read the release notes before doing an 
"Install" (step 3), if desired. You can also read them after installation.

3. Tap the "Install" button. This will install all software and firmware that 
is newer than what you have at present. 

NOTE: When the load process has completed, if you see any error messages in the 
status area of the update screen, please try loading a second time. This is a 
one-time step that may be needed that takes advantage of improvements in the 
updater itself.

For more detailed information, tap the "?" button on the LCD from within the 
update screen.

[Elecraft] “Direct connect” of a K3/0 to K3s feasible/possible?

[Paul GACEK via Elecraft]

Is it possible to connect, using just copper wire a K3/0 to a K3s and forgoing 
a pair of Remote Rig devices?

The use case is a K3s rack mounted in my house and a lot of cat6 (4x pair of 
copper) wire running around that is not connected to my LAN.

The K3/0 would be in another room and I’d use a free cat6 to connect the /0 and 
the k3S. Scenario is CW.

Given it’s last order time on K3 parts, I want to check feasibility of the K3/0 
without spending a fortune on the remote rig boxes given my use case is intra 
house.

Anyone have any ideas or direct experience?

I've decided it's time to get serious about saving money for a K4 purchase in 
the not-to-distant future. My KX-3 (S/N 62**) gets very little use, so it's 
time to let it get. The radio has only been used a few times outside for 
backyard or picnic table "dxpeditions."

This is a fully loaded radio with all options (except for the 2-meter module), 
It includes:

* KXFL3 - dual bandpass roofing filter
* KXAT3 - automatic tuner
* KXBC - charger (with realtime clock) for internal NIMH batteries
* MH3 - hand mic
* KX3-PCKT - accessory cable package
* KXSER - radio-to-computer USB cable
* Pro Audio Engineering KX31 heatsink
* Nifty Mini-Manual for the KX3
* Fred Katy's book - "The Elecraft KX-Line."
* The Elecraft KX3 Owners Manual

I think 60% of the original price is fair for this pristine radio. $1200 plus 
Priority Mail shipping ($21.90) to any US ZIP Code.

I will be happy to send pictures to anyone seriously interested in the 
purchase, if you can put up with my primitive photography skills.

Peer into the side of the KPA100 (the side where the coax and power

done.  If you can only see red toroid cores in about the middle of the 
board, the lastest update is not installed.

Re: [Elecraft] K2 #7997 is alive

[Doug Person]

Building a K2 takes quite an investment of time. But, once you've 
completed it and made your first QSO where you proudly say "Rig here is 
an Elecraft K2 that I just finished building...", you have a sense of 
ownership unlike anything you just took out of a box and plugged in. 
It's a marvelous little transceiver. It's truly fantastic for cw but 
shines in SSB as well. I can't recommend the experience enough. I've 
learned to have a very ZEN mind when I built them. Total focus on 
exactly one thing - a resistor, capacitor... what ever it is... do it 
perfectly and don't think of anything else. And then admire its 
perfection when its done. When I finish a board, I inspect it with a 
quality magnifying glass. I look at every solder joint, every part 
placement like it's a work of art - which, in many ways, it is. Whether 
it becomes your main radio or sits on a shelf awaiting an occasional use 
- it is always a source of personal pride. To me, building something 
like the K2, is a very important part of the Ham Radio Experience.

The KPA100UPKT totally revamps the T-R switch section on the KPA100,

There is a chance that there may be a nasty spur when on 40 meters -

comes sometimes creeping or sometimes suddenly. It seems to have 
something to do with the transmit / receive switching. I checked this 
very carefully with an HP8664A signal generator and a spectrum analyzer. 
Sometimes both receivers are exactly the same, then the main receiver 
slowly gets worse and worse (within a minute the amplification drops by 
6-8dB) sometimes it happens immediately after switching from RX to TX 
and back. Then it happens that after switching from RX to TX and back 
again, both receivers are the same again. It can also happen that the 
main receiver is initially 8dB worse than the second receiver, but 
without RX / TX switching the missing 6-8dB are suddenly there again - 
in the middle of receiving mode, without switching. So it's intermittent 
and it drives me crazy not to find out what's going on. Is that another 
bad pin diode somewhere in the main receiver and if so: which one? Maybe 
someone has an idea? Help is very much appreciated.


This is a K3 #56xx with all features and all upgrades so its more or 
less a K3S rather than an K3.

Re: [Elecraft] Share a port for KPA500

[Steve Forst via Elecraft]

Tnx to Andy and Bob for the feedback on this.   Yes the manual says that 
the Main / Sub radios must be connected at 115,200 bps, and while it was 
some time ago,  my testing here  seemed to prove it true.


The 890 does install 2 virtual com ports for the USB connection: 
standard and enhanced. The standard port is used for radio control 
and audio in and out.The enhanced port seems to have limited 
functionality.  It's a little beyond my skills and abilities to figure 
out if the  band data  is available here and if so, how to  get it to 
the KPA500.



I've gotten away with a single receiver for decades, so no big deal, or 
I can just go with the RF sensing on the amp.


Tnx again, Steve KW3A

I also have a TS-590SG that I can use as a second receiver  for the 
TS-890.   For this to work right, the sub RX needs to connect to the 890 
via the serial port with a null modem cable and set to a 115,200 baud rate.



Is there a simple way to get the band data to the amp while the 2 radios 
are connected to  each other as described above?


I guess I can use the amp's RF sensing, but  have always loved having 
the amp follow the radio.
