[Elecraft] Protecting the Sub RX input

2015-01-27 Thread Ken G Kopp

I have one of the Array Solutions units protecting my K3.  FWIW,  I have a
KPA500 and a number of antennas on a two acre lot. Translates to lots of
cross-coupling.

Release Notes: 

MCU 01.35 / 1-22-2015

* Added stepped span mode, like the PX3, span is stepped 2, 5, 10, 20, 50,
100 & 200 KHz when enabled.
* Added per-band noise blanker enable and level. 
* Added serial commands: 
#NBnNB enable, sets/gets on/off 
#NBLnn  NB level, sets/gets level 
#SPMn   Span mode, sets/gets
#SVWBnn SVGA waterfall bias, sets/gets

Re: [Elecraft] Receiving AM on the K3 - Odd behavior

 Subject: Re: [Elecraft] Receiving AM on the K3 - Odd behavior

Harry,

Others may have replied off the list, so what I say my be redundant:

You are confusing RF bandwidth with audio bandwidth.

For AM 6-KHz RF bandwidth is proper for best quality demodulation and 
either AM or FM filters work as bandwidth is controlled by DSP ckts 
and not by the roofing filters.  Audio output of the K3 is limited to 
4-KHz so you will note that you cannot open the bandwidth higher than 
4-KHz in SSB (FM is fixed and you will see "N/A" if you try to adjust 
the "width" knob).  BTW I see 5-KHz displayed at max width in AM on 
my K3 (still, I believe audio is limited to 4-KHz)(I am using the 
13-KHz roofing filter for AM).

Note: I do not have the P3 so what it displays may be counter to what 
I have said (my comments are for the K3).

Content-Type: text/plain; charset=UTF-8

I noticed something odd when receiving AM.
I have the AM and the FM filter installed and both enabled for AM Receiving.
The manual states:In AM mode, the I.F. bandwidth required for good 
fidelity is about twice the AF bandwidth.?This is why a 6 kHz or 
wider crystal filter is needed to effectively use the 3 kHz 
NORM?setting. If a 15 kHz FM filter is installed, it can be used in 
AM mode to provide good?fidelity at even higher AF bandwidth settings.?

Watching on The P3 as I adjust the Filter width between 1.3 kHz and 3 
kHz it tracks properly but?between 3 kHz and 5 kHz it's really only 
varying between 3 kHz and 4 kHz (with 4 being the max)?3 = 3 , 3.5 = 
3.25, 3.5 = 4, 4.5 = 3.75, 5 = 4
I confirmed this by loading up Spectrogram and looking at the audio 
output and it tracks the same way.
To further test I went in to SSB mode set FC to 2 kHz and BW to 4 kHz 
then moved the shift ?to 2.2 kHz and the output moved to 4.2 kHz and 
the P3 tracked it as well as Spectracom.
I also looked at the Spectracom display in FM Mode with the squelch 
open ?and it appears that the audio?stages could easily reproduce out 
to 6 kHz with little roll off and ?even displayed out to a bit over 18 kHz.

Have others noticed this?

 Subject: Re: [Elecraft] K3 Sub Receiver and protecting the Sub RX input

In general, ensure the coupled energy into the receiver antenna 
connector is less than 1 watt under absolute worst case conditions, and 
preferably under 100 mW, and your receiver should be OK.

Put another way, the antennas should be separated by 40 dB if running up 
to 1 kW, 30 dB if running up to 100W and 20 dB if running up to 10W.  
You might get away with 10 dB less coupling. If you can't get this level 
of isolation by physical separation and/or orientation of the antennas, 
provide some external means of reducing the signal to the receiver input.

Yes, the K3 inputs are tested to higher levels than this, but why stress 
the radio and risk damage to or degradation of the receiver(s)?

If you hear the receiver COR relay click when using the other 
transmitter, reduce the coupling between the antennas or otherwise 
prevent the excess energy from reaching the receiver input.

Re: [Elecraft] Receiving AM on the K3 - Odd behavior

2015-01-27 Thread GRANT YOUNGMAN

If you use Sync AM mode, the K3 is single (selectable) sideband on AM.  The 
bandwidth you see displayed is NOT the DSB bandwidth, it is the bandwidth of 
the ONE sideband that is being received.  So if you open the bandwidth display 
to say 4 kHz, in sync mode, you are receiving one sideband, with an IF 
bandwidth of 4 Khz and and effective DSB bandwidth of 8 KHz.

IMO, the sync AM mode in the K3 is one of the best sync detectors I’ve used 
(pick one, I’ve probably used it).

Re: [Elecraft] K3 Sub Receiver and protecting the Sub RX input


Ken,

I am not Wayne, but I can tell you that you question does not have a 
single answer.
Do you run an amplifier?  More power requires greater separation between 
the TX and the RX antennas.


Another factor is the orientation of the antennas.  An RX antenna in the 
null pattern of the TX antenna will not pick up a lot of TX RF, while an 
RX antenna broadside to the full TX antenna RF will be a problem.


If the antennas have orthogonal polarity (one horizontal and one 
vertical), that will reduce the pickup on the RX antenna during TX.


So a lot depends on the type of RX antenna, its orientation, its 
directivity, and a vast array of other factors.  There is no one answer 
to your question, it all depends on your installation.

Re: [Elecraft] PX3 with "other" I/Q Receiver?

2015-01-27 Thread Tom Blahovici

Hi
It would not work properly as is. I think one would need to send information to 
the px3 via the serial port to establish the centre frequency,  markers, and 
respond to qsy''s.etc. as well as react to requests coming from the px3.
Assuming these are standard api type  commands it could be a possibility. Could 
be a fun project.

Re: [Elecraft] K3 Sub Receiver and protecting the Sub RX input


Phil,

The K3 ANT1 and ANT2 connections are not of concern, they are protected 
by the T/R circuits in the K3.


The AUX ant is protected by a COR (Carrier Operated Relay) that will 
activate if there is too much RF being brought in by the AUX antenna.  
While it should protect the K3 (and KRX3) from damage, you will hear the 
COR clicking as you transmit.
If you do hear such relay clicking, the "cure" is to move the RX antenna 
further out of the field of the TX antenna, or provide some form of 
external 'protection' such as shorting the RX antenna input during TX or 
alternate means of disconnecting the RX antenna during RX.

I ordered the sub receiver and in the conversation with Elecraft I was 
informed that it is good idea to build a device that would short the 
dedicated RX antenna to ground to protect it during transmit.
The simple way would be a relay but I'd rather not hear a relay click 
with each transmission.

I was wondering what others are using to accomplish this.

Thank you

Re: [Elecraft] Remote Rig RC-1216H use with KPA500

2015-01-27 Thread Barry Baines

Eric:

Thanks for the suggestion.  Some of the software options are certainly worthy 
of a closer look.

Since my primary use of the K3 is through remote access, I'm looking for 
simple, reliable equipment connections that allow as much flexibility  as 
possible with minimal "fuss."  Here are some thoughts for your consideration:

1.  While the use of a PC at the radio site is certainly an option, it also 
introduces an additional failure point as well as extra cost as the PC is up 
and running all the time.  It also adds to complexity by having to setup, learn 
and run two different software packages, one on the PC at the radio site and 
another on the laptop at the operator's location.

2.  The RC-1215H approach is far simpler to install as it is a stand alone box 
with a RS-232 connection to connect the KPA500.  All it requires is an ethernet 
connection. No special software is needed, only an internet browser as the 
"smarts" in the device interfaces with the RS-232 data coming/going to the 
amplifier.  Any OS can be used on the connecting computer (Mac, Linux, Windows, 
even a tablet such as an iPAD through WiFi) as it is "cloud computing" with no 
special software. 

3.  The RC-1216H complements the Remote Rig with K3/0-Mini as it makes possible 
full control of the KPA500 and the Remote Rig setup allows full control of the 
K3.  

4.  As the popularity of Remoting increases, operators will be looking for 
simplified solutions to gaining full control of their ham stations.  What sold 
me on the K3 was the K3/0-Mini, allowing full front panel control of the K3 and 
good audio connections between station and remote location.  I had some initial 
"hiccups" due to my network configuration, but once those problems were 
resolved, it has been fun to use.  I do have the ability to remote turn my 
rotator and use the WN-2 through a USB-to-Ethernet device from Digi 
International called Anywhere/USB2.  However, this approach requires the use of 
Windows as Digi International only provides drivers for Windows.  

5.  I don't currently have a good way to control the KPA500 without using a PC 
at the shack and for the reasons above would like to avoid it.  FWIW, in using 
a Lantronix serial-to-ethernet device in order to avoid the PC at the shack, 
I'm able to remotely connect to the KAT500 from the "control" PC from my remote 
location and thus avoid the need for the PC at the shack, but this approach 
still requires Windows on my local PC (e.g. MacBook running Parallels/Win7 Pro 
or run Bootcamp w/Win7 Pro) due to Lantronix and Digi International only offer 
Windows software utilities for a personal computer to create the serial ports 
for their devices to work with.   So far, I have been unable to get the KPA500 
connection using a Lantronix serial-to-ethernet device as the interface.  

Given Elecraft's apparent interest in creating relatively painless solutions 
for remote operations, I would encourage the company to consider future 
offerings for full complementing of remote operations, including amplifier, 
tuner, and rotator control.  Stocking the RC-1216H and offering the unit as 
part of the Remote Rig package through Elecraft is one option. Developing your 
own "box" that can handle the KPA500 and KAT500 through ethernet interface and 
web browser interface is another option.  Looking at key station accessories, 
such as rotors, and offering an integrated package that includes these 
components is a third option. In each case, the ability to connect seamlessly 
through a browser offers real advantages since the user can then use whatever 
platform (Windows, Mac OSX, Linux) they prefer.  That said, there is the 
question of how to interface the rotor so that reporting of antenna position 
and commanding rotor positioning can be accomplished while running logging and 
other programs.

I Can recommend the Elecraft sw for control of both KPA and KAT. Using it via 
Teamviewer and HRD (both available as freeware) You Can easily control the 
entire combo ( K3, KPA and KAT) from Remote PC. Really no need for expensive 
external boxes.

Right now I am doing just that from EA8.

Re: [Elecraft] K3 Sub Receiver and protecting the Sub RX input

This would only be necessary if you're running high power and/or the antenna to 
be used with the KRX3 is close to the transmit antenna. Could you describe your 
antenna system?

Re: [Elecraft] Panadapter

I generally agree, Jim -- though the PX3 even with 
this limitation is better than no panadapter at 
all. And it's far nicer than the Tiny Python 
Panadapter (April 2014 QST) I built earlier.


But I sure hope Wayne and others figure out how to 
add Fixed Tune mode to the PX3; I'd use the rig 
more if it had that capability.


Wayne has mentioned Fixed Tune Mode for the PX3 
("carefully", I'd say) in past posts. Maybe he'll 
chime in with an update.

This is a BIG negative for me. The current

GREATLY reduces its usefulness. To see weak

the noise near the bottom of the amplitude

So, is this limitation of the PX3 going to be fixed to support the fixed tune 
mode.  Fixed tune is about the only way I use my P3.  Although I need to

I am not going to answer your question because I have no answers about

However, I can offer you an alternative that I find useful.
First, I have programmed the first 10 K3 memory locations with "Quick 
Memories", so I do not have to use the band up/down buttons - just tap 
M>V and then one of the number buttons to switch to the last used 
frequency on a band.

Then I have programmed memories for the M1-M3 buttons on each band. M1 
takes me to the center of my operating range for CW, M2 for DATA modes, 
and M3 for SSB.
I reserve M4 for saving any frequency/mode of interest on that band - a 
double tap of the V>M button followed by a tap of the M4 button will 
save any frequency/mode of interest so I can return to it with a tap of 
the M>V button followed by a tap of the M4 button.

I know that is not exactly what you asked, but it works for the way I

Re: [Elecraft] Receiving AM on the K3 - Odd behavior

2015-01-27 Thread Edward R Cole


Harry,

Others may have replied off the list, so what I say my be redundant:

You are confusing RF bandwidth with audio bandwidth.

For AM 6-KHz RF bandwidth is proper for best quality demodulation and 
either AM or FM filters work as bandwidth is controlled by DSP ckts 
and not by the roofing filters.  Audio output of the K3 is limited to 
4-KHz so you will note that you cannot open the bandwidth higher than 
4-KHz in SSB (FM is fixed and you will see "N/A" if you try to adjust 
the "width" knob).  BTW I see 5-KHz displayed at max width in AM on 
my K3 (still, I believe audio is limited to 4-KHz)(I am using the 
13-KHz roofing filter for AM).


Note: I do not have the P3 so what it displays may be counter to what 
I have said (my comments are for the K3).

<631043647.573239.1422324055017.javamail.ya...@mail.yahoo.com>
Content-Type: text/plain; charset=UTF-8

I noticed something odd when receiving AM.
I have the AM and the FM filter installed and both enabled for AM Receiving.
The manual states:In AM mode, the I.F. bandwidth required for good 
fidelity is about twice the AF bandwidth.?This is why a 6 kHz or 
wider crystal filter is needed to effectively use the 3 kHz 
NORM?setting. If a 15 kHz FM filter is installed, it can be used in 
AM mode to provide good?fidelity at even higher AF bandwidth settings.?


Watching on The P3 as I adjust the Filter width between 1.3 kHz and 3 
kHz it tracks properly but?between 3 kHz and 5 kHz it's really only 
varying between 3 kHz and 4 kHz (with 4 being the max)?3 = 3 , 3.5 = 
3.25, 3.5 = 4, 4.5 = 3.75, 5 = 4
I confirmed this by loading up Spectrogram and looking at the audio 
output and it tracks the same way.
To further test I went in to SSB mode set FC to 2 kHz and BW to 4 kHz 
then moved the shift ?to 2.2 kHz and the output moved to 4.2 kHz and 
the P3 tracked it as well as Spectracom.
I also looked at the Spectracom display in FM Mode with the squelch 
open ?and it appears that the audio?stages could easily reproduce out 
to 6 kHz with little roll off and ?even displayed out to a bit over 18 kHz.


Have others noticed this?

Re: [Elecraft] K3 Sub Receiver and protecting the Sub RX input

2015-01-27 Thread Edward R Cole

An alternative to a relay (which should ground the sub-receiver ant) 
is using a pin diode to short the input.


Typically one uses a coupling capacitor to isolate the antenna from 
the circuit which will have a low value of dc bias to turn on the pin 
diode which will conduct to ground and short the antenna ckt.  I 
assume the K3 sub-receiver antenna ckt is capacitively coupled to 
isolate it dc wise.  Use a RF choke between pin diode and antenna to 
keep from loading the antenna in normal use.  hint: google pin diode 
antenna switching.


Use KEY OUT ckt from the K3 to control the pin diode via a transistor 
switch that applies the bias thru a dropping resistor.  You will have 
to do some design work - not plug-n-play freebie


Many ham rigs that do QSK use pin-diode TR switching.

change frequency. Once (or if!) that is added to 
my PX3 it will be well-nigh perfect.

Re: [Elecraft] K3 Sub Receiver and protecting the Sub RX input

2015-01-27 Thread Mike K2MK

There are a couple of things to think about. How much power are you running?
How close is the receive antenna to your transmitting antenna? Does your
receive only antenna possibly have an interface that can connect to the key
out of the K3? (My Pixel Loop antenna has such a device)

You can also try it out and listen for a clicking noise from the carrier
operated relay inside the K3. It is a protective relay that will energize if
it sees too much power coming in on the RX antenna input. If you hear it
clicking then it is a good idea to consider additional protection.

There are external protective devices available that you can purchase. DX
Engineering and Array Solutions have them I think there are others out
there.

[Elecraft] K3 Sub Receiver and protecting the Sub RX input

I ordered the sub receiver and in the conversation with Elecraft I was informed 
that it is good idea to build a device that would short the dedicated RX 
antenna to ground to protect it during transmit.
The simple way would be a relay but I'd rather not hear a relay click with each 
transmission.
I was wondering what others are using to accomplish this.

Thank you

Re: [Elecraft] Remote Rig RC-1216H use with KPA500

2015-01-27 Thread Eric Swartz - WA6HHQ, Elecraft

We also have free full remote control software for the KPA500 and KAT500 on our 
K3 Software page.

http://www.elecraft.com/k2_remote.htm#k3remote

I use these with my remote station. 

These windows programs include both the host and client programs and they 
provide complete access to the KPA500 and KAT500.

Also of interest is the free remote software from remotehams.com .  (The 
author, Brandon, works in our engineering group and we are a sponsor of his web 
page. ) It includes embedded Voip and control of the K3, KPA500 and antenna 
rotors that support the high gain serial protocol. This is the s/w I also use 
for my remote operation.

Bit of a learning curve on FLDigi, but excellent signal reports and substantial
