Re: [Elecraft] will utility programs run on Apple Ipad os ?

[Barry Baines via Elecraft]

Howard:

I’m not aware of a iOS program that manages Elecraft equipment directly.  If 
you do a search on the App Store app found on the iPad, you can look at a 
program developed by KS7D that apparently interfaces with a PC that in turn 
accesses the Elecraft gear.  However, it hasn’t been updated in over a year and 
it isn’t clear to me how compatible it is with iOS13.x.

In the case of the KPA500, an alternative might be to use the Remote Rig 
RR-1216H to attach to the serial port of the KPA500 and then access the 
RR-1216H through a web interface.  I use the RR-1216H to manage the KPA500 and 
a second one to manage my Green Heron controller while operating remotely.  The 
RR-1216H has a configuration specifically for the KPA500; as far as I know 
there isn’t a configuration for the KPA-1500. The RR-1216H can be accessed with 
any web browser platform such as the iPhone, iPad, Android, etc.

At this point the only ’true’ iPad app for controlling a transceiver and 
amplifier remotely is SmartSDR for IOS for the Flex-6000 series and their PGXL 
amplifier.  I would expect that after the K4 is released, ’someone’ may develop 
a similar capability for the new Elecraft transceiver and associated equipment.


Hope this helps,

I’m using a Lantronix EDS4100 to provide the Ethernet-to-Serial conversion.  I 
specifically use this for the KAT500 where I convert the serial to ethernet and 
then use the Lantronix software to convert back to serial on my laptop at the 
location where I am.  Through port forwarding I can specify the Lantronix 
device remotely for configuration/monitoring using a web browser.  The ham 
station is in Southeast Georgia (near the Florida border) and I connect to my 
station when I’m in Texas or Massachusetts.  

I also used the same Lantronics device for a second serial port to connect with 
my rotor controller.  However, I’m now using the Remote Rig R1216H which can 
control a Green Heron Rotor Controller. I also use a second R1216H to access 
and control the KPA500 rather than use the Lantronix device to connect through 
a serial connection.  The key advantage of this approach is that I can manage 
both the KPA500 and Green Heron RT-21 via a web browser using any device that 
has a browser (MacOS, iPhone, iPad, etc.).  The Lantronics works well, but can 
only be used with a Windows PC as their software for converting 
ethernet-to-serial is Windows only. I do run Windows on a Mac via Parallels 
software and run the Elecraft KAT500 utility, and the Lantronics port software 
works well in that environment.

I have no experience with the UDS2100, but it appears to be a more advanced 
device than the EDS4100, so I would expect that it will meet your needs.

Re: [Elecraft] FT8 Problems

How is your swr at the longer wavelengths? I figured out my lousy
signal reports on 80 were because I was radiating inside the house off
the feedline, as the antenna wasn't resonant.

Good luck in any case,

Re: [Elecraft] K3 KAT3

[markmusick]

Larry,
Are you sure you didn't have ANT2 selected when you really should have been
on ANT1? Or the other way around.
When you disabled the KAT3 I think it defaults to ANT1.
I've had this happen before. All bands work but one. The one that doesn't
work has the wrong antenna output selected.
Now how did it get switched from ANT1 to ANT2? Who knows for sure, but I was
probably intending to operate RX ANT button or some other function and hit
the ANT button by mistake.

My K3 seemed to develop a problem on 20 meters this evening.  Trying to work
Marquesas this evening on 20 cw the K3 would not transmit and basically no
receive.  I checked every other band and all worked as usual.

The moment the radio went into transmit, I received Hi SWR on the screen
with or without the antenna tuner

I then reloaded all of the software and still nothing.  I tried to force the
tuner into auto tune by selecting my 160 meter dipole for 20 meters and
still nothing.  I finally went into the Config menu and disabled the KAT3.

All now works.  I never use the KAT3 anymore since I have the KAT500 and
KPA500.  Has anyone else had the KAT3 fail on 20 or do I need to open the
rig up and reseat all of the contacts?

Thoughts?

[Elecraft] Triggering a T-1 re-tune over coax?

[Steve Sergeant]

We're considering using a couple of T-1 tuners for a field event as
remote tuners on non-resonant antennas.

I can imagine some solutions, but at the moment I'm asking about prior art.

Has anyone built a hardware hack that lets one trigger a T-1 to re-tune
by sending D.C. over the coax? If so, can you point me to any articles,
designs, videos (if you must), or cell-phone-camera photos of the
napkin-based document?

We're going to be running 50 meters or so of coax to each antenna, so
running an additional control line seems like too much trouble.

Any disparaging of remote-tuner, non-resonant antennas, or advice on any
tuner other than the T-1 will be ignored as off-topic.

[Elecraft] K3 KAT3

[Larry Boekeloo]

My K3 seemed to develop a problem on 20 meters this evening.  Trying to
work Marquesas this evening on 20 cw the K3 would not transmit and
basically no receive.  I checked every other band and all worked as usual.

The moment the radio went into transmit, I received Hi SWR on the screen
with or without the antenna tuner

I then reloaded all of the software and still nothing.  I tried to force
the tuner into auto tune by selecting my 160 meter dipole for 20 meters and
still nothing.  I finally went into the Config menu and disabled the KAT3.

All now works.  I never use the KAT3 anymore since I have the KAT500 and
KPA500.  Has anyone else had the KAT3 fail on 20 or do I need to open the
rig up and reseat all of the contacts?

Thoughts?

Larry, KN8N

Dude!  That's awesome  One of those would fit between the uprights 
on my shack desk/hutch with 0.2" to spare...  Most efficient use of 
space possible in my setup... dual inputsKVM...


IF ONLY it had an external power supply... :-(

I'd like to pick up a couple of HDMI displays to hang on the wall

What can people suggest for quasi-affordable *RF-quiet* 4k displays in
the 27-40" range? (I'm not averse to buying something like one of the

Re: [Elecraft] 4k monitors for the shack, late 2019

[Rick Bates, NK7I]

It would be nice if you want to stream video while in the shack; I'm 
considering one also (but HDTV is much cheaper).  But one feature I 
would need is decent PIP (picture in picture) to watch two things at 
once (computer/radio and video source).


Two major things to consider are look angle and proximity.  If you have 
to look up more than a few degrees, your neck will whine, straight ahead 
is ideal.  If it's too large and close, it will be more difficult to 
take it all in or you move your head...  consider your ergonomics 
carefully, body parts resist movement, more each and every year.  It 
WILL matter, in time (or now).


73,
Rick NK7i

Re: [Elecraft] 4k monitors for the shack, late 2019

[Richard Eversole]

You may want to try cheap 4k tv... Some under $200... Several under $280...
Some use dc connector. I was going to try a couple and see... If they are
ng then return... For nongamers these should be fine... Under $200 means no
roku or other bells and whistles Seen nonham reviews that indicate
picture ok...

Tv's seem to be rca and Chinese off labels
For monitors LG and Samsung seem ok

In my earlier post, I forgot to mention that some displays are noisy and 
some are quiet. Years ago, someone gave me a Samsung with touch on-off 
control that was both very noisy and also turned flips when it sees a 
lot of RF. Which is why he gave it to me. :)


Most noise from displays is radiated by the video cable and the power 
cable, and that component of noise can be suppressed by winding turns 
through a #31 Fair-Rite core.

Re: [Elecraft] 4k monitors for the shack, late 2019

[Raymond Sills via Elecraft]

As I replied to Paul:
I'm not going to run out and buy one of those but in it's defense... it IS 
designed for high level video use, as in network edit rooms, or graphics design 
rooms.  It has many display refresh rates, so it can marry into various TV uses 
in many countries.  It's meant to be a professional product.  There are studios 
that spent that much on just a microphone, let alone a broadcast TV camera and 
its lens, which costs more than a car.
I solve the whole issue by simply not having a shack.  All my operating is a la 
portable.  So, I don't need any monitors.

Re: [Elecraft] 4k monitors for the shack, late 2019

[Richard Thorne]

Scott,

I've been looking at the following monitor 
https://www.newegg.com/lg-43ud79-b-43-uhd/p/N82E16824025629  The price 
recently dropped as it used to be in the $600+ range.


Watch the video on the LG site.  You can have multiple inputs. For 
example your main computer and maybe the output of the K4. It will be 
nice if and when DXLabs or N1MM can integrate dx spots onto the 
display.  Imagine having the K4 plugged into a large monitor and a mouse 
plugged into the K4.  When a spot you need or want shows up on the 
pan-adapter use the K4 mouse, click on the spot and bam, the rig is on 
frequency.


I'm currently running a Dell 34" curved monitor which has lots of real 
estate.  I'm thinking real hard about the LG 43" monitor because of the 
dual inputs.

Why 4K? I own a half dozen 23-in 1920x1080 Samsung displays that 
nominally use 14VDC, but run just fine on 12-13VDC. The major source of 
noise for most displays is the switch-mode power supply (wall wart) that 
provides that DC voltage. I cut the cable for the noisy power supply, 
splice it to an old linear supply. I've gone a step further -- I run the 
monitors in my shack from a big 12V battery that runs other ham gear, 
and float-charge that battery with a suitable charge regulator.


Since I bought these (about $200 each), the trend has been to higher DC 
voltage. Also, larger and higher res displays tend to use higher voltage.

Re: [Elecraft] Adding PTT Out Switching to a K3

[Don Wilhelm]

Pete,

To my mind, the PTT and KEY OUT nomenclature used by Elecraft is 
entirely correct and completely descriptive of what each does.  Yes, I 
know that some other rigs use PTT and KEYOUT interchangably, Icom 
confuses my mind more by labeling the KEYOUT with SEND.


PTT is what you do to put the transceiver into transmit - Push To Talk. 
That may be like activating the PTT button on the microphone (I shudder 
when a ham talks about "keying the mic" - to me that is CB talk) or it 
can be from an external device such as a footswitch.


KEY OUT is just what it says:  It is an output signal that is to be used 
to key other devices (such as an amplifier) when the transceiver is in 
transmit.

Don W3FPR

While I'm on the subject, I wish that Elecraft would clean up their 
terminology - their use of "Key" to denote PTT is confusing.  See the 
back panel of the K3, for example, which has PTT IN and KEY OUT jacks in 
the same row.  I believe this usage originated with CB.

[Elecraft] 4k monitors for the shack, late 2019

Hello all,

I'm going to continue to eagerly await a K4 for A While. In the
meantime, I've been reconfiguring a room to become my shack, and am
slowly terraforming it.

I'd like to pick up a couple of HDMI displays to hang on the wall
above/behind the rig and the computer I interface to it. Viewing angle
will be shaded, pretty much on-axis due to location, and it will be
right next to the entry of my feedline. Expected usage would be
waterfall/UI and pskreporter type apps.

If the open circuit (unkeyed) voltage*/is the same polarity/* for both

you can connect a diode in series with each keying line. Then connect

I need to be able to disconnect the antenna to my SDRs when

this - I don't believe sequencing is required, just a second PTT output.

Re: [Elecraft] Adding PTT Out Switching to a K3

[N4ZR]

Well I'll be darned.  I just pulled that cable out of the K3 and it is 
indeed redundant.  I must have missed that in the manual.  Thanks, Bob.


While I'm on the subject, I wish that Elecraft would clean up their 
terminology - their use of "Key" to denote PTT is confusing.  See the 
back panel of the K3, for example, which has PTT IN and KEY OUT jacks in 
the same row.  I believe this usage originated with CB.

If you're asking about third party apps running locally on the k4, Wayne's
been pretty clear that won't happen.

If you're asking about ability of things like wsjtx to drive it, they've
indicated that will be preserved and encouraged. I would not be surprised
if there are alternate UIs/clients built on their client APIs

Re: [Elecraft] Adding PTT Out Switching to a K3

[Don Wilhelm]

Tom,

To the best of my knowledge, there is no external signal from the K3/K3S 
to indicate whether ANT1 or ANT2 is active.


If you have any manual switching in place, incorporate it in that switching.

Re: [Elecraft] [K3] Relay click - SOLVED.....

[markmusick]

Ray,
I echo John's advice.
I use the DXE-RG5000 on the inputs to my K9AY Beverage antenna switch.
This protects both the main and sub-receivers.
You do not want to rely on the relay in the K3 high RF input circuit.
It is not intended to be the main protection for the receiver.
If the relay is operating, it is telling you that you need additional 
protection for the receiver or need to move the receive antenna further away 
from the transmit antenna.
By the way, K3LR uses the DXE-RG5000HD in his contest station. It is tried and 
proven.

Why not reduced the RF to a safe level on the RX line?  I would try something

and move the wire further away if possible to ensure that you do not damage the

[Mike Flowers]

Thanks, Bob.  I powered it off and on a couple of times and it came roaring 
back to life.  

 In many ways this behavior Is just as disturbing.  

When I have a couple of hours I’ll put it on the bench and exercise (gently) 
the internal connectors, etc.  

Thanks for your suggestions!!

Re: [Elecraft] Adding PTT Out Switching to a K3

Connect the KPA-1500 via the ACC cable and thus free up the PTT

use this method with my KPA500 and KAT500.


The PTT Out is connected to the VHF transverter.

Re: [Elecraft] Adding PTT Out Switching to a K3

[donovanf]

Hi Pete, 


If the open circuit (unkeyed) voltage is the same polarity for both devices, 
you can connect a diode in series with each keying line. Then connect 
both diodes to the KEY OUT (not PTT !) jack. 


The voltages do not need to be identical , just the polarity

Subject: [Elecraft] Adding PTT Out Switching to a K3 

I need to be able to disconnect the antenna to my SDRs when 
transmitting. This used to be easy but now my PTT Out jack is committed 
to the KPA-1500. I'm looking for suggestions of how best to accomplish 
this - I don't believe sequencing is required, just a second PTT output. 

Ideas?

Re: [Elecraft] [K3] Relay click - SOLVED.....

[David Olean]

Hello Ray

I built an RF limiter to put in my 2nd receiver line. It consists of two 
toroids and a pair of 1N914 or other fast diodes. Basically you step up 
the impedance to a pair of diodes and then step it back down to 50 
ohms.  Mine limits nicely at about 0 dBm or so. You can buy similar 
stuff at DXE I think.

Re: [Elecraft] K3 #2257 woke up deaf this morning ...

[Bob McGraw K4TAX]

Check all connectors.  I've found that connectors that just "sit" and 
are never moved will oxidize and prevent signal flow.   They rely on a 
mechanical connection only.   Just unplug and re-plug 2 or three times 
for each one.

Hi Folks,

  


I powered up my trust K3 #2257 this morning and found it deaf.   The RF and
IF stages appear to be working just fine.  I have 20M FT8 showing lots of
signals on my P3, but no audio.

  


WSJT-X shows no audio from LINE OUT either.

  


I'm on the right antenna and haven't fiddled with parameters for months, so
I am wondering if there is anything I might try/check before taking it over
to Watsonville for repairs.

  


Thanks!

Re: [Elecraft] AXE1 assembly problem

[Mike Parkes]

Thanks to all who replied on this issue. As it turned out the missing part
somehow ended up on the bottom of the whip, instead of inside the base on
the AXE1. Elecraft customer support was also very helpful and replied
shortly after I sent my support question email. Thank you Rob at Elecraft
for your help on that!

Re: [Elecraft] [K3] Relay click - SOLVED.....

[john]

Why not reduced the RF to a safe level on the RX line?  I would try  
something like this https://www.dxengineering.com/parts/dxe-rg5000hd  
and move the wire further away if possible to ensure that you do not  
damage the receiver.

[Elecraft] Lantronix UDS2100

[Hans Johansson]

I have a KPA500 and a KAT500 at my remote QTH and I want to
remote control them over Internet. For this I am planning to use
a Lantronix UDS2100 ethernet-serial server at the remote radio site.
Is there anyone on this list who has experience of controlling the PA
 and Tuner via Internet with KPA500 remote and KAT500 remote
programs in the computer at the control site.
The control way will thus be:
Control computer - router - internet - router - Lantronix server - KPA500
and KAT500
