Maybe transmit into a dummy load and listen on a different receiver? You should 
get enough leakage to hear the K1.

Re: [Elecraft] bizarre 30m ---> 20m K1

[Don Wilhelm]

Lloyd,

Take a look at the crystals on the 2 band board.  The crystal for 40m 
will be 15MHz, the one for 30m will be either 18.0 or 18.1 depending on 
whether you have the 150kHz or 80kHz VFO tuning range.  The crystal for 
20m is 22MHz.

How can this be. This transmitter is on 20. 10131 = 14031.

[Elecraft] K4 UI extensibility: "REM ANT" switch, Fn switches, automatic macros, and host-curated custom controls

[Wayne Burdick]

The other day someone asked me whether we might add remote antenna rotator 
control to the K4 front panel. This is a good time to point out a 
characteristic that's baked into the K4's user interface: extensibility. 

For example, we included a dedicated switch function called REM ANT. (This is 
the "hold" function of the main ANT switch.) We'll be able to add multiple 
antenna-related controls to this switch. It might bring up a rotator 
controller, remote antenna switch controller, even custom switching for complex 
stations -- right on the K4's screen. You could assign labels to custom 
functions or name your antennas to improve usability.

Like the K3/K3S, the K4 also has programmable function switches. But it has 
many more of them. There are four dedicated switches (PF1-PF4) above the 
RIT/XIT offset control, plus another 14 tap/hold functions accessible by 
tapping the "Fn" soft switch on the LCD. 

Any of these programmable controls can be used as simple shortcuts to 
often-used menu entries or other functions. We're also planning to include 
means for setting up switch "macros" (collections of commands) either manually 
or automatically. 

Users of our existing transceivers may already be familiar with manual macro 
setup. In this case you'd enter a string of K4 2-letter commands as text. 

Automatic macro setup will work differently: first you'll select a programmable 
control as the target, then record any combination of other controls to it by 
activating them in the desired order. 

For example, suppose you frequently use two different waterfall heights (as a 
percentage of total panadapter height). You could manually enter the text for a 
switch macro using the pertinent commands. In the automatic method, you would 
start macro record, adjust the waterfall to one of the desired values in the 
usual way, then stop macro record. That Fn or PFn control would now perform the 
same operation with a single switch activation. This could be repeated to add 
other custom settings.

Another example is setting up the VFOs and second receiver for DXing. You might 
start macro record, then tap A>B twice (copying both frequency and mode, etc.), 
then offset VFO B by 2 kHz, turn on the second RX, and set the passbands for 
the two receivers to useful starting points. When you terminate macro record, 
you'll now be able to do all of this with one press.

Taking things a step further, the K4 will allow external computer applications 
to "curate" their own controls on the K4's LCD. In its simplest form, this 
would allow an application to send details of one or more custom menu entries 
to the K4. These menu entries would appear in the K4's own menu, typically in 
the "APPS" category. The user could then make changes to the external 
application's settings directly from the K4's screen when it isn't convenient 
to do it at the computer.

Of course this will also work the other way around. Virtually all K4 functions 
will be controllable from computer applications capable of sending control 
commands via USB, RS232, or Ethernet.

Wayne

You might want to check the PLL Reference Oscillator Range on that K2 -

Jim,

There is no relay action when changing from VFO A to B or the other way
around - the MCU just sends different data to the PLL and PLL Reference
Oscillator.

However, 20 MHz may be on the lower limit of the available VFO tuning
range for 15 meters.
Try tuning the VFO for both A and B back into the 15 meter band limits.

The K3 will transmit and receive in the 8 MHz range as long as you're using 
direct sampling mode. The HDR module (in the K4HD model) has an 8 MHz I.F., 
like a K3, so it would have to be turned off in this case.

[Elecraft] KPA1500 Command Macro PF1 PF2 Buttons for fast Fan Control

[Mark Murray via Elecraft]

These two front panel PF1 PF2 button macros have served me well for
quick access & control of fan speed.  They're not perfect, but they're
still quite a time-saver from having to look over at the amp and scroll
through the main MENU items to find FAN, and then make the selection to
EDIT, and then make the selection of speed change.  If the op is
unfamiliar with programming PF1 and PF2, please see the notes below.

Macro For PF1 :^BPT11;^FS;^FC1;^BPH11;
Macro For PF2 :^FC0;^BPT03;

If desired, a first long press of PF1 triggers Fan Speed 01 and leaves
the LCD screen fixed in the FAN SPEED window.
If desired, a second long press of PF1 triggers the Fan Speed EDIT
function to allow fast or slow changes in fan speed.
If desired, pressing PF2 turns the fan off and returns the LCD screen to
regular amp STATUS window.


Note-1:  The amp's firmware will (supposedly) provide necessary fan
overrides when heat conditions require such.  
Note-2:  Amp Firmware used was v.02.17
Note-3:  I was unable to configure a single PF macro button to toggle
between FC1 and FC0.
Note-4:  PF Macros are configured and set using Utility > Configuration
> Edit Configuration > PF Keys tab
Note-5:  The KPA1500 Programming Reference has most all command format
possibilities,
  available at Elecraft.com, title: KPA1500 Release Notes
2.2.2019.E740328 ProgrammingReference Rev 2.03.pdf 

Having some fun with the fans and macros, 73 de MarkW2OR

Re: [Elecraft] The ERR 12V Message Question

[Drew AF2Z]

It's been a while since I did mine but I think disassembly/reassembly 
was a significant part of the effort. I did the front panel connector at 
the same time as the power connector. The actual removal of the 
connectors and soldering new ones went pretty quickly. I'm not sure I'd 
want to go through the disassembly for a "quick fix" only to have to do 
it again in another month.


You might want to refer to online blogs about the process, or Youtube 
videos (if any). Sorry, I don't have the links, but one hint: after you 
snip the connectors off the board use an alligator clip to grasp the pin 
stubs for desoldering; it's easier than trying to manage it with a pair 
of dikes.

[Elecraft] FOR SALE K2 SER#7750

[Robert 'RC' Conley]

LET'S TRY AGAIN:
I am relocating to a senior’s apartment complex and will not be allowed 
my ham station. As a result, my Elecraft K2 #7750 has to go.
When I built K2 #7750 it was intended to be a CW only station with 
computer control so only the KIO2 option was included.


I document all my builds. You can see the complete documented build on 
my web site at .


I had some issues, so I sent it to Alan Wilcox who fixed the issue, 
aligned it, and also built and installed the KIO2 option for me.
Then FT8 came along, so W5LA (Jim Ragsdale) built and installed the KSB2 
option for me as I no longer felt qualified to do the work.
Since Jan 24th until June 12th I have made over 2,500 FT8 QSO's, 
including over 500 QSO's as a W5L special event station with K2 #7750
and various wire antennas: an 80/40 trap inverted Vee and a 40/20 trap 
inverted Vee @ 75'. All with this K2 #7750. Sideband operation

is also available , however you supply the microphone.

I will greatly miss this radio. No need to clutter the reflector, so  
PLEASE reply off the list.
I am offering my Elecraft K2 #7750 for sale for $850.00 firm. I'll ship 
it USPS PRIORITY MAIL. I'll pay the shipping and the PayPal fees.


73, RC WW5RC ex KC5WA
