This is similar to a message I got yesterday. It came from some non-US
email address. It was someone saying they wanted to buy my K2 and to
tell them how much where to send the funds.
I just deleted the message.

Jim,
The change is only in the displayed width. Before it was the IF
bandwidth, and now it is the audio bandwidth - for AM, that will be 1/2
of the IF bandwidth, so 10 kHz before equals 5 kHz displayed now. It
is consistent with the other bandwidth displays that indicate the audio

George,
The K3 keys up to 200 volts POSITIVE via the Key Out jack in the back. If
your amps require negative voltage to be keyed you will need an outboard
relay.
You really do not need ALC, but if you want to use it, the signal is on the
accessory jack. Be sure your K3 has the negative ALC

I can almost guarantee this is going to be another one of those, My radio

The reason being, this phenomenon is level sensitive. With a weak signal the
noise reduction lowers the signal strength but above a certain level, it
increases the signal dramatically.
I have used 1N4007 diodes for this purpose and had no trouble! The last
relay I took care of was the keying relays in the old Navy TCS-12
transmitter I have. If you get across the key contacts when you are

I guess no-one except myself looked at the data sheets for the drivers.

Hi, I have used the diode snubber in all designs of relay control from small
reed to large contactors. I usually check the series resistance of the relay
and the non solid state device activation and measure the voltage kick. I
then use ohms law to determine the peak current that would occur
I downloaded the latest beta with the squelch and tried to set it up, but I
wonder if
there is something about it that I don't understand, or need to adjust

I was hoping I could basically set the squelch with the RF/SQL knob on the

Help:
Lance,
You have your choice of either an RF gain control OR a Squelch control
(but if you do not have the subreceiver, you can have both).
If you choose to have the squelch control, then the RF gain can be
handled by using the attenuator and the preamp, and the AGC will also
work to limit the
The flux can be very considerable! As the flux collapses it can induce a
very high voltage transient across the coil far exceeding the voltage
produced to energize the relay. There is a certain amount of energy stored
there in many instances. The 'back EMF pulse can wreak havoc with solid
Don - A couple of minor clarifications:
1. If you dedicate the Sub RF gain knob to adjust Squelch, you get a
combined RF gain for both RXs on the main RF gain knob.
2. If squelch is fully counter clockwise, it is always open with no
threshold.
This is all covered in the latest f/w release
Before, activating NR reduced the signal strength and sometimes drastically. A
few of us asked to put NR and NTCH inside the AGC loop to keep teh signal
strength even. It seems as if the firmware upgrade just increased gain with NR
but NTCH is definitely not inside the AGC loop yet.
Ignacy
Thanks for the clarifications Eric.
I do not have the subRX, so I assumed and we all know what that does.
You are correct about the SQL knob at zero. I do mentally relate it on
a relative scale basis to the S-meter - the higher it is set, the
stronger the signal must be to open the squelch.
Today I was listening around on 40m cw and messing with the Shift and
Width knobs. I had the NR turned on. I was running the Shift up and down the
range just casually listening to the noise pitch change. Retired people have
this kind of time. I had the width down to 50 hz then I hit the FIL
