Low Tx Data Sound Output volume

I am not sure if this is a Windows 10 problem or something changes in my
K3s settings and want to see if others have experienced the same thing?

When the K3s is in Tx Data (PSK 31 and RTTY) - AFSK -A LSB, I now find that
the data output (sound) is no much lower than when just in LSB mode. This
seems to have occurred with the latest Windows 10 update. Hence in this
weekends CQWW RTTY contest, I could only use MMTTY with the K3s in LSB mode
and not Tx Data mode. I am not sure if it changed something with the Codec
driver or by some fluke, something changes in the K3s settings. Hence, I
ran the contest in LSB versus Tx Data.
Thanks,

Re: Low Tx Data Sound Output volume

Irwin,

Did you get the information that Elecraft radios are different than
other amateur transceivers?, and that you have to set up the audio and
power differently. It sounds like you may not be setting the audio and
power correctly for the K3/K3S.

The common internet "advice" is to set the power to maximum, and use the
audio level to control the power output. That does not work well with
Elecraft transceivers - ignore that advice.

With the K3 (K3S, KX3 and KX2), set the audio to produce 4 bars on the
ALC meter with the 5th bar flashing and adjust the power with the Power
knob on the radio.

AFSK A should be no different than LSB except that compression and TX/RX
EQ is automatically turned off.

For PSK31 or other data modes, the use of DATA A submode (which is USB)
is recommended although PSK31 does not care about the sideband. Other
soundcard digital modes do care.

Please refer to the K3 Data modes article on my website www.w3fpr.com.
Scroll the left column down to the bottom and you will find the link to
the page.

Re: Low Tx Data Sound Output volume

With FLDIGI there are two modes for DATA. PKTUSB is preferred for all modes except where one chooses PKTLSB for AFSK. The CAT command will handle the radio mode switching. Thus one does not have to turn to the radio and initiate the REV mode.
