KX3 TX inhibit ?

All,

I plan to use my KX3 for RX only, connected to a 2m downconverter; I want to
be 100% sure that no power gets transmitted because of a n accidental
manipulation; is it possible to inhibit the trasmitter ?

I didn't find any hint in the manual.

Re: KX3 TX inhibit ?

Easiest way is to set the power output to "0W" -- this will prevent the KX3 from generating any RF.

R: KX3 TX inhibit ?

Thanks Matt, that's what I do today.
Still, the potentiometer could accidentally be turned, I'm looking for a
harder lock, multi-op-proof.

If you have the packet cable kit, you can ground the ACC2 line and set the
ACC2 IO menu option to LO=Inh (see page 35 of the manual for details).

R: KX3 TX inhibit ?

Thanks Mooner,

I would have preferred a menu option but you are right; I do have the cable
kit, if a shorted 3.5mm jack will be seen as LO I could use that as a kind
of Hardware-lock.

Thanks for the hint !

Re: R: KX3 TX inhibit ?

In reply to this post by Marco HB9CAT

On my KX3 I have to push in and hold the "PWR" (KEYER/MIC control) button to
get to the power settings. So, unless you accidentally press and hold, and
you will then see PWR displayed, I can't see how it can accidentally be
changed?

R: R: KX3 TX inhibit ?

Fair point Dave, but let's assume I want to modify the PBT I/II and press
the wrong button; that did happen to me a few times.

And particularly in a multioperator contest environment I must assume the
worst case and have a foolproof solution.
Missing a software setting I'll try the ACC2 solution.

Re: R: KX3 TX inhibit ?

I guess if you are letting oher people use the rig there's always a danger
that they might accidentally mess it up !!

I did hear a story about someone who got their 70cm radio back after a
contest, which had N-Type sockets for the antenna, where someone had forced
a PL-259 into the socket! So, I can see why you would want a fool-proof
solution in those cases...

Re: R: KX3 TX inhibit ?

Now all you need is a way to securly lock the 3.5mm jack plug in!

Experience of past contests/Special Event stations tells me that people are
strange creatures and do things that seem illogical. Like pulling out plugs
that they don't know what it does...

Anyway, I'll also make up a 3.5mm short circuit jack plug as well for times
when I do not want to accidentally transmit.

Re: R: KX3 TX inhibit ?

Perhaps it will be enough to set menue to "low=inh" without plugging in a shorted jack at
ACC2. My K3 works that way because the INH input is low by default.

R: R: KX3 TX inhibit ?

Thanks Win,

tried that, the inhibit is triggered only setting "low=inh" AND with the
shorted jack effectively plugged in.

I'd personally prefer Elecraft to add a menu item for this, but I realized
that it could potentially cause a pretty high number of trouble tickets /
returns because of "broken" TX.

Re: R: R: KX3 TX inhibit ?

Marco,
I had the idea of using some CAT-command to do so, but couldn't find a
specific one in the manual.
There is, of course "RX;" and "PCxx;", which would have to be sent
frequently. The VOX state command is commented as "GET only, SET is
planned".

In Win-Test, for example, you could assign a script to all Fx- keys, the
script looks like
wtRadio:Send("RX;")
wtRadio:Send("PC000;")
return -1

Happy contesting!

R: R: R: KX3 TX inhibit ?

In reply to this post by Marco HB9CAT

Right Mark, I shall just have used the opposite logic:

Setting "HI=Inh" in the ACC2 IO Menu de facto disables TX (TX blinking); so this is the perfect solution with no need for external HW.

Thanks for the hint !

The kx3 is different from the k3 in that the input is normally hi. If set txinh=hi it won't transmit unless pulled low.

Gernot,

Thought about it, but the dependency on CAT would be too risky; I have the
solution now, see previous post.
