K3 feature request

K3 feature request Hi folk,

i would like to have the key out connector switched during “Tune”. That would be a
useful improvement for tuning linear amplifiers.

Re: K3 feature request

G'day Uli,

KEY OUT switches on tune on #345. That is how I tune my Acom 1000.

Regards,

Mike VP8NO

Hi folk,

i would like to have the key out connector switched during ³Tune². That
would be a
useful improvement for tuning linear amplifiers.

***********************************************************************************************
dr. Uli & Mike,

After much consternation and thought, with also much help from the "Reflector-Group" out here,
what I did was utilize my "Heil-footswitch" to do everything (keying) I wanted it to do.

I say that because the FS has (2) lines out of it, on for keying the "KEY"/constant tone for
either
tuning your XMATCH or Linear and also for PTT for SSB instead of crappy VOX!!! Everything thing
here works great!!! My Alpha 91b amp works great because of it's QSK and the K3's as well!!!

Regards,

Jim/nn6ee
Concord, Ca.

Hi Mike,

How is your firmware version ? I use the latest one V 2.76.

Re: K3 feature request

I would like the key out not to switch on the amp when tuning the antenna
with a remote tuner without turning on the amp. That way when I operate the
amp is loading into a tuned circuit via the K3 tuning mechanism. I have the
ALS 600S

Re: K3 feature request

Ouch.. that could blow the pin diodes or protection circuits in my
internal Ameritron PIN5 QSK switch if the amp were in the "Operate" mode
and RF were applied from the rig without the KEY line activated. It is
imperative that the KEY line be actuated before RF hits the amplifier
input to avoid damage to the pin diode switch. With Ameritron amps with
an internal pin diode switch, the wiring is such that the only time the
amplifier is actually bypassed is when the OPERATE switch is in STANDBY.
Otherwise the path is to the amplifier input AND the pin diode switch.
In this mode, the KEY line only goes to the pin diode switch, not the
main OPERATE relay which would otherwise bypass the amp. I normally
don't put the amp in the "Operate" mode until after the antenna is tuned
using the normal K3 "TUNE" mode while the amp is bypassed. If I forget
to tune the antenna first and operate the amp I get a huge reflected
power (seen on the tuner bridge) but nothing catastrophic for a short
operation of my AL-1200. If the KEY OUT is to be optionally disabled
during K3 TUNE, it MUST be a menu selected option or it will result in
damaged equipment.

Just curious - how is the K3 supposed to "know" that you have an external
tuner that needs to be tuned so that it could do this?

A properly connected and adjusted ALC system that responds to
amp/antenna anomalies by signalling the rig to cut back on drive
might be useful. Don't know how it would respond to keying weirdness.

Re: K3 feature request

No PTT when tuning so it won't key the amp. Put it in the menu to switch
the PTT on or off?

Come on guys, why put this in the K3 or in any transceiver?
I really really don't understand why. If you are using an amp, set the
amp to standby. The K3 signal will go straight through. That's what it's
for!

You're right Arie! But when I forget to put the Alpha in STDBY it just refuses
to take the input and goes into STDBY ;O)
