In fact, one can not transmit above 2800 Hz (with the 2.8 KHz filter)
as the filter roll off (and perhaps DSP limitations) result in little
or no output.

It occurs to me that you might not be able to transmit on
frequencies much higher than 3KHz or so because of the limits in
the transmit bandwidth with the 2.7KHz filter.

Try in TX TEST mode - everything goes into transmit except there is no

Adjust the audio level (both SignaLink and the mic' gain on the K3) to
obtain 4 bars solid on the ALC meter with the 5th bar flickering.
If you are not able to obtain that level, check the SignaLink

As a K3 newbie here, would the mic impedance (H or L) be a possible issue? I
could not get any ALC movement until I went to H impedance for the Heil
headset I have. I was then able to get all the ALC needed

I suspect you set the powe5r to maximum and are attempting to control
the RF output with the audio level. That is typical advice given on the
internet and other data mode instructions. That advice is not for the

With the K3, ignore that common advice for

The K3 H or L in the mic select do *not* refer to microphone
impedance, but to the range of the K3 microphone gain. The Heil HC4 and
HC5 elements (and other low level output microphones) will need the H
setting. Most other microphones can use the L setting.

Be sure you are in DATA mode, not SSB mode. You will get no output in SSB
mode.

Jay,
The K3 H or L
Yes, the K3 will work for data modes using SSB. However, the DATA A
submode is preferred over SSB. The first advantage is that compression
is turned off, and the second is that the TX Equalization is turned off
too. If you have compression set for SSB and are using TX EQ, you will
need to
software has built in filtering/DSP so the wider
bandwidth on receive works very well, for PSK31, and other data modes.

My computer software has a choice of waterfall bandwidth, 2K
(from 400Hz to 2400Hz) or 4K (400Hz to 4400Hz). In both Data A
