John,
I don't know if or how that HRD does it, but remote power off is
available if the software issues a PS0; command to the K3. Note that a
powered off K3 is not listening to commands, there is no way to turn the
K3 on via RS-232 command. To turn the K3 back on remotely, an external

Alan,
Yes, the FTDI chipset adapters are the recommended variety.
To further confuse the issue with both Prolific and FTDI serial
adapters, there are counterfeit adapters on the market. Those worked
with few problems under Windows XP with the provided drivers, but both
companies included cod
Can someone tell me how to turn OFF my K3 radio remotely through HRD.
All I could find in the archives was this simple statement.

port, and then shut down the computer
This is late, but perhaps someone can provide me with a clue.
I loaded a new log for the CQWWSSB and started doing check outs on my
station. Everything is FB with the exception of the voice playback.
All settings are the same, and have not changed since last using this combo

I just got round to trying to interface my K3 to a PC.
I starred off with 2 different Prolific USB/RS232 cables, but although they

Paul,
The K3 does not use RTS or DTR for communicating with the PC, only RXD
and TXD and Signal Ground are used. So the setting of PTT - Key should
have no effect on PC to K3 communications. I suspect a serial port
problem or a serial cable problem.
Since you have real serial ports on your
I changed K3 PTT-Key to "OFF-OFF", that seems to have solved TX on turn on
problem. But now - not sure if related- K3 will not talk to PC serial port. I

K3 in all four and can't get it to connect. Also cannot get KPA 5
Jim,
Thanks for all the info. I hoped that you might respond. I have read a lot of
your articles. That’s a lot of homework. I suspected that it may possibly be a
combination of connection issues. I may look into the transformer as a
possibility or may just look for something simple with 2 unbal

I have NEVER got it to work correctly using MicroHam Router software.. I
need to runt the router software to use my Keyer 2R+ and Station master.
It runs for about two minutes and then crashes.. I would LOVE to get it

You're right, it will roll off on the high end, too, but the rolloff rate is
usually much less steep especially if series-tuned. An analysis of my tuner
shows that it would be only about 20 dB down at 30 MHz (when tuned on 40
meters) when parallel-tuned, and only about 10 dB down when series-t

Tim,
The KX3 works fine for MARS, I use it for AF MARS, no change to it is
required or no change to firmware or hardware is needed.
Only problem is it will not transmit from 25 MHz to 28 MHz, there are some
digital and voice nets in that freq range that I can not use with the KX3.
I do not use
Thanks for the replies. My question is answered. I really needed to know

Paul,
If the K3's "PTT-KEY" menu selection is set to something other than
"OFF-OFF" then the K3 uses the RS-232's RTS or DTR pins as a keying input.
The P3 has no internal connection to those pins. It just passes them
straight through between the "PC" and the "XCVR" connectors.
Do you have
Paul,
Have you disconnected the RS-232 cable to the PC from the P3? If not,
try that and then connect the RS-232 cable between the P3 and K3. If
the problem is resolved with only that cable in place, blame your
computer, but if the problem happens with no computer connection to the
P3, cont

I agree with you. I use Win4k3 as my rig control and HRD log and DM780. It
is stable and works great. It is nice to have my complete K-Line monitored

Tom has done a super job on this software. The Terminal part of it is also
easy to use and a nice feature.

Dave,
R39 for the XV50 should be a 1k pot. Typo or incorrect component?
The bias voltage is not the important factor, important is the ability
to produce the proper idling current - that is why the instructions tell
you to measure the voltage between TP3 and TP4 when setting the bias.

R39 is correct (10k pot) as is R10 (100k) and all the measurements
confirm this. The adjustment range, measured at pin 2 of the amplifier

maximum voltage is limited to 4.7V because of the 5mA flowing through
R28 which swamps the 1
Dave,
The PA bias control usually has much greater range than is needed, and
the PA bias input should draw very little current.
Check the resistance of R39. Is there a chance that you swapped R39 and
