The audio CODECs in the K3 have a 12 kHz sample rate. This puts the maximum

In addition to Joe's excellent advice, you may need to set the Tx output
level for the soundcard in DM780 to a higher-than-default level. In the
DM780 version I have on my computer, I have the Transmit Level sliders
for Master and Wave both set to about 70.

This problem is fixed in the latest beta firmware for the K3/K3S. Until
then, it is best to set PTT-KEY to OFF-OFF before taking the K3/K3S to a

The KX3 operates well in most environments in modes with reasonable
key-down times. Recognizing that more and more operators are using
digital modes with extended key-down times, we recently replaced the
supplied heat sink of the KX3 with one having significantly more thermal

The KIO3B includes an FTDI-based serial port (drivers widely available
for all sorts of OSes and versions of same) and a UAC1-compliant CODEC
(driver built in to most OSes since late in the last millennium). It

Ted,
The discrepancies in instructions are due to the KPBF3A instructions
being written with the K3S in mind, while the KBPF3 mod instructions
