Re: [Elecraft] Dual Receivers 2 different antennas Diversity receive

[E.H. Russell]

I also get excellent results pairing a 39’ vertical with resonant dipoles and 
inverted vee’s spread around the yard not far away. Because of the close 
proximity and QRO, I have a RF protector/limiter on the vertical.

I notice a big increase in intelligibility of cw signals in conditions of QSB 
and even QRN with diversity on 40 through 10 meters (well, at least I have dim 
memories of 15/12/10 m). 

My antennas are only about 10m apart, but one is a horizontal dipole and the 
other is a vertically polarized small loop (a “pixel loop”, now made by DX 
Engineering). The dipole is also about 5m higher than the loop.

Re: [Elecraft] Dual Receivers 2 different antennas Diversity receive

[John K9UWA]

You could use a device such as the KD9SV  FES "short for Front End Saver" The 
Device removes and grounds the receive antenna input during transmit. Yes it is 
fast enough for QSK. You can also run your PTT line to your amplifier through 
this 
device. If the Device fails to work that prevents the amplifier from being 
keyed.

[Elecraft] No Longer Deaf K3!!!

[John Unger]

Thanks to Rick, N1RM, and his expertise in tracing circuits, my K3 is back
in FB working order. We found that a switching diode on the bottom
(fortunately) of the RF board had failed. (I think it was D25.). It was a
low cost fix, and with Rick's surface mount skills a replacement was soon
installed.

Rick's main expertise in working with ham equipment is repairing ACOM amps,
but fortunately he had the ability and equipment to help solve my K3's
problem.

Thanks for all the ideas and feedback here on this reflector.

Frank,
My read of your comments is that it is all OK. If you are getting 
power out, you're on the air. Nothing to do but operate. Pick some 
strong station calling CQ and give him a call. And, see what happens. 
There should be nothing else on the rig to fiddle with at this time.

Currently I'm interested in trying VOX in order to enable running multiple

Are you in Data A mode and do you have anything plugged into the Line IN

Line Gain on the radio is typically is set for 30 to 40 using the MIC 
control on the front panel.   And with the others,  set the ALC bargraph 
to show 4 to 5 bars and then set the PWR value on the radio to that 
which you desire to operate.  The PWR slider on WSJT-X is set in the 
upper 3/4 of the scale, depending on SPKR level set on the computer.   I 
use 30 to 35 for SPKR level on the computer.

Re: [Elecraft] K3S, VOX and WSJT-X?

[Frank O'Donnell]

Bob,

First, let me back up and say that I'm operating with the K3S in 
transverter mode on 630m with an external power amp. I've successfully 
used CAT control with WSJT-X on a MacBook Pro to tx/rx JT9 and WSPR. My 
objective now is to use the K3S in VOX mode with a Windows 10 desktop 
running two instances of WSJT-X, and one instance each of SlowJT9 and 
JS8Call. I'm told that a number of ops do this with other brands of rigs 
to allow the decoders to rx simultaneously, and to tx with any of them 
without any reconfig necessary (though obviously only one app can be 
used to transmit at any given time). At this point, I have all the 
decoders running simultaneously and successfully decoding incoming 
signals. Now I'm just working on getting VOX mode working to transmit.


As things stand now, when I click Tune or enable transmit in WSJT-X, the 
Windows audio system indicates that audio is going out to the USB Codec.


To answer your questions, nothing is plugged into the Line In on the K3S 
rear panel. When I started working on this, the K3S was in split mode 
with Data B selected. In order to get into Data A, I first needed to 
disable split mode. I then enabled VOX. The levels you mentioned all 
appear to be set appropriately.


Now, if I click Tune or enable transmit in WSJT-X, the K3S reenables 
split mode and switches to Data B. The red transmit light never comes on.


Undoubtedly there's another setting I need to do something with?

Thanks and 73,

Frank K6FOD

Re: [Elecraft] K3S, VOX and WSJT-X?

Rich,

I don't think CAT control is necessary in this case, because in this 
configuration, all of the tx/rx is on one band (630m) and one frequency 
(474.2 kHz, used by JT9, WSPR and other digital modes, unlike HF bands 
where they are on different frequencies). I haven't yet found anyone 
else with a K3/K3S operating in this configuration on that band, but a 
number of ops with other brands of rigs set things up this way, with 
several decoders running all in VOX mode. I assume there must be a way 
to do this with the K3S.


Thanks and 73,

Frank K6FOD

However, you also said you wanted to run multiple instances of WSJT-X.
That's a different matter, and PTT/VOX is only a small part of it. If you
try to run more than one instance of WSJT-X, only the first instance will
be able to use CAT control. Any other instances will not be able to open
the serial port used to control the radio, so they will not have CAT
control of any kind, including not only PTT control, but also frequency and
mode control.

JT9 uses CAT control not only for PTT, but also for frequency control
(split operation, and/or specific frequencies for different modes on
various bands). The instance you use for JT9 and similar modes should
probably have full CAT control. WSPR, on the other hand, does not really
need CAT control once you have tuned the transceiver to the correct
frequency for the band.

Re: [Elecraft] K3S, VOX and WSJT-X?

Frank,

Although several others have had success with VOX, I find the most 
reliable is to use PTT via CAT command.  Set it in the application and 
you will have no problem.


If your problem is related to audio levels, refer to my website 
www.w3fpr.com.  Scroll the left column to the last article and click to

mode or the normal antenna, you must have 4 bars solid with the 5th bar 
flashing on the ALC meter.

Re: [Elecraft] K3S, VOX and WSJT-X?

[Frank O'Donnell]

Don,

Thanks for the comment.

CAT has always been the PTT method I've used with WSJT-X, and it's been 
very successful. It would normally be my first choice.


However, I just ran across this interesting configuration that some 
number of 630m ops are using, using other brands of rigs. Since all of 
the digital modes on 630m are based off the same frequency of 474.2 kHz, 
they set their rigs to that frequency and then use VOX control to allow 
several decoders on the same PC to rx simultaneously, and tx one at a 
time without any reconfiguration. I gather this couldn't be done if the 
decoder apps used CAT, as only one app can have CAT control of the rig 
at any time.


So I wanted to give this a try. So far I have several decoders receiving 
simultaneously from the K3S, and it's nice to have JT9, WSPR, SlowJT9 
and JS8 all being decoded at the same time. I'm just having challenges 
getting transmitting to work with VOX. I know the PC is sending audio 
out the USB Codec when I hit the Tune button in WSJT-X, and I know VOX 
works on my K3S because I use it for CW. Just trying to knit the final 
details together.

Frank,

Although several others have had success with VOX, I find the most 
reliable is to use PTT via CAT command.  Set it in the application and 
you will have no problem.

Hi Gordon,I have a KX2 s/n under 250. I'm not a hiker but I operate on the 
ocean beaches in WA state and up at Mt Rainier NP. In the field I use the AX1 
ant on a camera tripod. Works very well. The only mod was the 2nd harmonic mod 
to the transmitter. Excellent portable/field radio!Enjoy 73Jim hk7...@aol.com

[Robert Cunnings]

What is your VOX gain setting?

with WSJT-X on a MacBook Pro to tx/rx JT9 and WSPR. My objective now is to 
use the K3S in VOX mode with a Windows 10 desktop running two instances of 
WSJT-X, and one instance each of SlowJT9 and JS8Call. I'm told that a number 
of ops do this with other brands of rigs to allow the decoders to rx 
simultaneously, and to tx with any of them without any reconfig necessary 
(though obviously only one app can be used to transmit at any given time). At 
this point, I have all the decoders running simultaneously and successfully 
decoding incoming signals. Now I'm just working on getting VOX mode working 
to transmit.


As things stand now, when I click Tune or enable transmit in WSJT-X, the 
Windows audio system indicates that audio is going out to the USB Codec.


To answer your questions, nothing is plugged into the Line In on the K3S rear 
panel. When I started working on this, the K3S was in split mode with Data B 
selected. In order to get into Data A, I first needed to disable split mode. 
I then enabled VOX. The levels you mentioned all appear to be set 
appropriately.


Now, if I click Tune or enable transmit in WSJT-X, the K3S reenables split 
mode and switches to Data B. The red transmit light never comes on.


Undoubtedly there's another setting I need to do something with?

Thanks and 73,

Frank K6FOD

Re: [Elecraft] KX2 ... Any KX2 users on this list?

[Wayne Burdick]

Hi Gordon,

It's a safe bet that there are a thousand or more KX2 owners represented on 
this list. There are also many frequenting the KX2/KX3-specific list, 
elecraft...@groups.io. 

I use mine every weekend :)
