Thanks to everyone that emailed me with responses, this learning curve for
SO2R is steep !

[Elecraft] Mouse and P3 SVGA

[STEPHEN R]

There is a lot of room in the P3 box. Put a small microprocessor in there that 
would control a mouse. Why not? Sure would make the P3 and SVGA work better. 73

Re: [Elecraft] Mouse and P3 SVGA

[Fred Jensen]

There are a large [possibly infinite?] number of ways to "do" most 
everything.  Driving faster than light may be one of the exceptions.  
Doing them profitably over a sufficient period of time is another 
difficult challenge.

I seriously thought of ordering one to replace the KPA500 at the remote,
but I'm going to give www.rf-kit.de a try.  It is a similar put it together

 When I go to transmit, all is well; when the transmission should end,
 the tones stop as expected, but the KX3 stays in transmit (until I hit
 the XMIT button).  Clearly something is amiss.

[Elecraft] K3 users with SteppIR interface

Ok, guys, I will be getting a new 3 element SteppIR soon. I have a K3 and a P3. 
I want to use the SteppIR interface to have the antenna track frequencies as I 
turn the dial. I used to do this on my old Pro 3 with the SteppIR I had about 4 
years ago. As I understand it, you connect the SteppIR interface cable to the 9 
pin port on the back of the K3. Problem is that I use Ham Radio Delux and there 
is already a cable from the computer to the K3 using that port. I would like to

Re: [Elecraft] [KX3] New behavior using JT65

Dave,

You still may want to check that cable - or perhaps the soundcard has a 
high noise floor.

When the audio stops, the KX3 should drop out of transmit when using VOX.
Of course, I don't know what happens if VOX and PTT are asserted together.
Cables are always one of the high failure items in any system.

[Elecraft] New behavior using JT65

I reboot the system, and things go the same way; no effect.

[Elecraft] K3 for sale

[Joe Hoffman]

My beloved K3 is on it's way to the mother ship in Watsonville to migrate a few 
things to my new K3S.  Once that is done I would like to sell it and perhaps 
even have it shipped to a new home directly from Elecraft if payment is made 
prior to it leaving Watsonville.

Here is what I have for sale then:

K3 S/N 1713 with the 100W module, the KAT3 ATU and the KXV3 transverter module.

If you are not familiar with the migration process note that any needed repairs 
(which I do not expect) would be charged to me.  Shipping from Elecraft will 
also be charged to me.

My K3 is in excellent operational and cosmetic condition with nary a scratch on 
it.

I would like $1750 for it shipped to your door.

73,

Joe, W8JH

Re: [Elecraft] SO2R Antenna/Band Information

[Joe Subich, W4TV]

On 5/25/2017 3:22 AM, Matthew Cook wrote:

No.  Each will require a binary (BCD) to one of 16 (10) decoder to drive
"one line per antenna" switches.  The K3 will provide encoded band info,
the MK2R+ can provide either encoded band info or encoded antenna info
depending on data source.

MK2R+ can derive data from transceiver frequency with a customizable
band table (Router | Options | Band Map) that would allow one to
define separate "bands" - for example 80 and 75 meters - or can derive
either band or antenna based on the SO2R protocol commands generated by
the logging software.  The choice is made on the ACC tab in Router
(assignments for pins 6-9 and pins 10-13) as well as in the way the
logging software is configured.

Using the "Band Data" from the K3 is probably more simple while using
MK2R+ is more flexible.


Logically the same but time differences or local user input can make
the two different.


There is no time difference with CAT derived band data.  The logger
command driven antenna select data is sent when the loggers change
transmit focus, when the user selects an alternate antenna from the
logger, or the logger senses a manual band change on either transceiver
(bad idea - get used to changing bands from your software).  In any
case, any antenna/band changes should be sensed long before the logger
initiates any transmission.

I'm currently trying to get my head around where to get antenna band

I believe I can pick up band information useful for making antenna
selections from the following two locations;

- from the 15-pin ACC (between K3 and KPA500 via Y-Cable)

I'm wondering if there are any pitfalls or hidden gotchya's in either of
these two locations.

To me it seems more sensible to slave the antenna section to the KPA500's
since it knows where it will be transmitting when PTT is engaged; where as
the back of the Microham MK2R+ is where "it thinks" or "has told" the radio
and amp should be...   Logically the same but time differences or local
user input can make the two different.

Any suggestions or guidance gratefully appreciated.

The Microham MK2R+ that arrived today certainly has a steep learning curve !

Re: [Elecraft] K1 - VFO frequency range

[roney]

Hello Mike and Cameron, I appreciate your tips.
I adjusted the L1 inductor, getting 3.500,3 mhz and 20.098,2 mhz on VFO.
That was perfect to me.

(updating Cameron about the email)

So I moved the rig to another place and used another PSU (first using a
12,4v, and after using a 13.8v PSU)
I noticed that this minimum frequency changed to 3.501,2 mhz.
No problem about that.

Thanks and 73,
de PY1ZB, Roney

[Elecraft] Impatiently waiting...KPA1500

[Jim Miller]

Sold off my KPA500 and ACOM1500 and now barefoot with K3s.

This waiting will no doubt make me crazier than usual. :-)

I'll be low power in WPX CW this weekend.

[Elecraft] P3 external touch screen

[Mike Keller]

Hi

With Field Day around the corner, I am planning to bring a larger LCD monitor 
than I use on my P3 SVGA when in my shack to enhance the visual experience of 
our guests. I have noticed that since last Field Day, the prices of touch 
screen monitors have fallen precipitously

 Our current generation of young prospective Hams are definitely touch screen 
oriented and I think they would find it attractive.  Is there any way to use 
one with the K line?
I am not adverse to using additional hardware.

Tnx,
Mike 
W1BNC
K lines 2 and 3

[Elecraft] SO2R Antenna/Band Information

[Matthew Cook]

I'm currently trying to get my head around where to get antenna band
information for a K-line SO2R setup using a Microham MK2R+.

I believe I can pick up band information useful for making antenna
selections from the following two locations;

   - back of the Microham MK2R+... or
   - from the 15-pin ACC (between K3 and KPA500 via Y-Cable)

I'm wondering if there are any pitfalls or hidden gotchya's in either of
these two locations.

To me it seems more sensible to slave the antenna section to the KPA500's
since it knows where it will be transmitting when PTT is engaged; where as
the back of the Microham MK2R+ is where "it thinks" or "has told" the radio
and amp should be...   Logically the same but time differences or local
user input can make the two different.

Any suggestions or guidance gratefully appreciated.

The Microham MK2R+ that arrived today certainly has a steep learning curve !
