WSJT-X Disabling TX INHIBIT on K3S

I asked this question previously and was told that the WSJT-X would not effect TX INHIBIT on the K3S.

In trying to confirm this just now, TX INHIBIT is clearly disabled when I call CQ on FT8 digital mode.

Any thoughts?

Re: WSJT-X Disabling TX INHIBIT on K3S

John,

Contact the WSJT-X developers to see if any command they issue would
disable K3 TX Inhibit. Since the exchange on FT8 is so rapid, my guess
is that they may very well disable TX Inhibit as a "safety" measure.

There is nothing about DATA A mode operation of the K3/K3S that would
cause TX Inhibit to be disabled.

Re: WSJT-X Disabling TX INHIBIT on K3S

Don,

Thanks for that.

Just in case anyone else asks, I thought you could only select .1 or .2 seconds delay under ADVANCED settings in WSJT-X. It turns out, you can enter any delay you want. So, problem solved.

WSJT-X Disabling TX INHIBIT on K3S

In reply to this post by stengrevics

"was told that the WSJT-X would not effect TX INHIBIT on the K3S."

I did a quick check on my TS-590S with WSJT-X ver 1.9.1. TX inhibit is not cleared by WSJT-X and there is no transmission. If WSJT-X could clear a TX inhibit it would, in my opinion, be an appalling design flaw.

I have been suggesting to a TS-590S user that they could use TX Inhibit to protect their rig when using an antenna switching system that takes longer to change from RX to TX than the maximum RF onset delay of the TS-590S. If WSJT-X could clear that inhibit it would make that protection useless and could cost hundreds of dollars in repair bills.

Re: WSJT-X Disabling TX INHIBIT on K3S

How does one implement TX Inhibit on a Kenwood TS-590? I would
like to include that information in some of the support material
I produce for other products that interface with Kenwood rigs
among others.

I find no mention of a TX Inhibit in my review of the TS-590
Instruction Manual (or the Instruction Manual for any other
Kenwood transceiver).

"How does one implement TX Inhibit on a Kenwood TS-590?"

On a TS-590S TX inhibit is menu 60. The EX command is used to change menu settings over CAT. For a TS-590S -

EX06000000; reads the inhibit status

EX060000001; sets TX inhibit

EX060000000; clears TX inhibit

For a TS-590SG the menu number is 66 so substitute 060 with 066 in the commands above.

Note that, like almost all menu selections, the inhibit will only apply to the menu (A or B) in which it was set. To be safe it should be applied to both menus.

Re: WSJT-X Disabling TX INHIBIT on K3S

Wow, and I have heard that the Elecraft menu items were "cryptic"
One does not get any more cryptic that those Kenwood menu entries.

At least the Elecraft menu items are spelled out in abbreviated English
and not a string of numbers. For instance the TX INH menu is not menu
#60, but is labeled TX INH in the VFO B display. It is easy to scroll
through the menu items to select the one of interest. VFO A changes the
parameter in plain language as well. Normally no need to refer to the
manual unless the operation of the menu item is in question.

"At least the Elecraft menu items are spelled out in abbreviated English and not a string of numbers. "

Setting TX Inhibit from the Kenwood TS-590 menu simply requires selecting the menu number, where the selection is declared in plain English, and then selecting "on" or "off".

If you want to compare setting menu items over CAT then please do so. Don't compare selecting menu items over CAT to selecting menu items on the rig.

Without an eternal control line (inhibit), the Kenwood TX Inhibit
is more like the Elecraft Test Mode (allows operation but no RF
output). I'm looking for that external control.

Andy;

Are you saying that you have to send the radio a serial command to engage and disengage the inhibit property? I don’t see how that is really useful for SO2R where you need pretty much instant switching, but then I doubt that is its use on the Kenwood.
That leads to the question of how the TS590S is protected in an SO2R or similar multi-tx environment.

Hi,
WSJT-X does not touch TX Inhibit.
The only command that WSJT-X sends is a TX; command to enter transmit mode
or it asserts DTR or RTS. The same is true for Yaesu and Icom transceivers.
Now if the radio does this itself behind the scenes, that is another story.
But 100% for sure WSJT-X does not send the TX inhibit menu command.

"Are you saying that you have to send the radio a serial command to engage and disengage the inhibit property?

TS-590 TX Inhibit can be activated by CAT as I described or by a manual menu selection. There is no hardware TX inhibit for the TS-590S or TS-590SG. I think that is a significant deficiency in the design. I think N1MM uses a software lockout in a TS-590 multi TX operation (only keys one TX at any time) but I have no experience of that implementation.

Tom,

I was told that. All I can say is that there is no delay from the K3S when I transmit on WSJT-X. I increased the delay to .3 seconds under ADVANCED in WSJT-X settings and the problem is solved.

Re: WSJT-X Disabling TX INHIBIT on K3S

In reply to this post by stengrevics

I've not checked in detail what PTT inhibit the KX3 has, but I have
tripped it up on one occasion in the past, but I forget how how I
un-tripped it!

Certainly in some circumstances an external "interlock loop" could be
useful to have, or a key switch on the front!

On my TS870s, Menu 27 set to ON, utterly disables the front panel TX and
Tune buttons, and both the Mic PTT, Aux TX line, VOX and the CAT TX command!

It's state is remembered when powered Off too, so is useful if you have
kids (or cats) in the house and when developing custom software that
will use the radio.

(The Aux port TX line needs to be used, so as to route digi-mode audio
from that port to air, and mute the Mic.)

Many Kenwoods also have a "feature" that if the Mic PTT is active when
they are powered up, they will not TX, but locks out the transmit
ability. Many have been caught out by a faulty Mic that way!

I don't know, but maybe Elecraft have implemented that last one, I've
not tried that on the KX3. If I remember, I'll try later.

I do know that if you momentarily feed the KX3's Mic jack's PTT line a
+ve voltage (I forget exactly, but somewhere greater than +3V) it will
power up the radio from the OFF state! Very useful for a QRP remote.
Once "awake" the PTT line works as normal. A CAT command is used to
power down the rig when you're done.
