Simple logic on your part, and careful inspection and application of a

We have a problem with our k3 tx bandwidth.
Firmware is the last stable version.
This k3 was used in E4X.
In the config menu we have selected the 2700 filter for TX, but TX bandwidth
is around 1800.
We tried to solve it, but finally the k3 had to be used in cw.
What do you think?

Are you sure you're not in CW? There is no auto notch in CW, only SSB mode.
(or some other mode I'm not aware of)
That was it. Thanks!

I use DXLab's Commander, its rig control module, with its user-defined

My setup has a PR781 on the front input and a Heil Proset Plus on the rear.

Just installed a sub RX in my K3, mainly for the purpose of making things
easier when working DX with split - finding the calling station's frequency
and moving my TX freq there.
Before getting the sub RX I did this by holding REV while adjusting VFO A
knob to center the calling station in the

main receiver and knob. When I have found him, I then press the AB button and
put the sub receiver on his frequency and then tap sub. Then I tune the main
VFO to the frequency that I want to transmit and I don't
Mike,
The contour is nothing more than a Notch/Dip filter or a Peak filter (you can
change it's function in the menu). Basically you center the contour in the
center of the pass band (pitch freq) and you can set it to either Push up that
signal (no different than if you set your Pitch freq.
The contour...
The reason I chose 400Hz is because unlike the contour which can variably
move through the entire pass band area (600Hz - 900Khz) , with the K3 you
only get a specific Freq. settings for each EQ setting.
In CW mode you also have DUAL PB which tracks your PITCH setting.

I also added the GaAsFet 6M preamp to the station and
Actually you can't do that with the K3 at narrower bandwidths in CW. The RX
EQ is deactivated at narrower filter settings. (Unless this changed in a
recent firmware release). I don't recall what the cutoff width is and I

Thanks to everyone for the suggestion (and variations thereon) of not using

I just noticed my VFO B knob was cracked; I rarely use it, so don't know how
long it has been that way. A three minute phone call to Elecraft and the
replacement is already in First Class USPS mail. I don't know how it could
get any simpler than that. No mention of any charge either.

John,
Yes, the PR6 can be used on the K3 with a single TX/RX antenna - if the
KXV3 option is installed in the K3.
The PR6 is easy to place in the RX only path if the KXV3 is installed.
The KXV3 option has RX ANT OUT and RX ANT IN connectors - the PR6 is
normally placed between those two

Set 'TUN PWR' = 020 so you have 20W for tuning the Acom.

Was operating on 17M SSB with NR on. Went to change AGC setting. When
it cycled through AGC off, the NR turned off. It did not return when a
more slow or fast AGC was selected.

Hi Brian,
It's always been like that. The manual says NR is not applicable in
DATA and FM modes, or with AGC turned off. When you say it did not
return when a more slow or fast AGC was selected, I assume you mean
it didn't automatically turn itself back on when you re-enabled AGC.

I also added the GaAsFet 6M preamp to the station and it makes a HUGE
difference on Six.
It needs to be pointed out from time to time that whether the PR6 makes no
discernible difference or a HUGE difference depends on one critically
important variable: YOUR NOISE

That's the way the K3 operates.
There are two mode groups; CW/FSK D/PSK D and SSB/AM/FM/DATA A/AFSK A.
Note the A in DATA A and AFSK A ...
So no solution? I want VOX to be on no matter what band im on when i select

when I switch from doing digital modes i occasionally forget to turn VOX off
and i go into TX.

I'd have to go check but I'm pretty sure that VOX is remembered per
band/per mode so you just have to set it that way and it should remember
it.

You seem to be right. The VOX state is also not retained when programming

Also check your VOX level in the menu. It needs to be turned up very
high when using it for digital modes. You are correct to use DataA for
PSK and other audio based digital modes. AFSK can be used for RTTY and
gives you the advantage of using the dual peak filters. Other than that
