Andre,
I have not measured the K3 line out signal level - it does depend on the
input signal level to the antenna.
However, it should work fine with most recording devices, unless that
device presents a low impedance input (which would require more driving
power).
You could try reducing the series resistors on the input side of the
isolation transformers (see page 8 of the K3AFMDKT instructions) which
may help. The mod kit addresses distortion, but should also help to
increase the output level.

Hello everyone! Greetings from northeast of Brazil!
I think this topic has somehow been discussed before but it was not
conclusive. Forgive-me in case I´m wrong.
While trying to make audio recordings using the K3 line level output
and my Marantz PMD620 handheld audio recorder
(http://www.d-mpro.eu.com/index2.php?CID=3&Pid=139&action=detail&lang=eng
<http://www.d-mpro.eu.com/index2.php?CID=3&Pid=139&action=detail&lang=eng>)
I found out that the output level of the/my K3 (#1164) is not high
enough to make a good recording, no matter I turn the CONFIG LINE OUT
to 100%.
I´ve used the same Marantz recorder many times, plugged in others
receivers/transceivers, and most of the times I´ve to attenuate the
input level to avoid overload and distortion.
Is something wrong with my K3? Can the AF stage upgrade help me with
that? According to the K3 project, what is the nominal line level
output of the K3?
Thanks in advance.
André Santos, PT7AT
