K3: As remote Base

Hello,

I am considering the use of a remote base type of setup to get away from
the RFI in my area. I have finally given up on trying to fight it, and
want to move the rig away from the city, as opposed to hunting down and
correcting every new RFI source endlessly.

My station consists of a KPA500, P3, and K3. I am using a P3 external
keyboard, running an external computer to do FT8, and finally CW via the
radio, not using a computer.

Is there a system which would allow the same functionality I now have,
remotely via the Internet?

Remote operation is certainly feasible, but it does introduce new considerations/tradeoffs. I’ve been operating remote since purchasing my K3 system in 2014 specifically for remote operation. About 80% of my operating is done remotely.

1. I use a K3/IO-mini with the Remote Rig setup to control the K3 because the K3/IO-Mini front panel is the same as the K3 and I avoid the need to use a computer to control the K3.

2. I control the KPA-500 using the Remote Rig RC-1216H as it provides a web-based front panel that matches the KPA-500. As it is a web-based interface, I can use any device (Mac, ioS iPhone or iPAD, Windows PC) to access the KPA-500 front panel.

3. I have the KAT-500 Tuner which I am forced to run the Elecraft Utility to manage it. I have a serial-to-ethernet converter in the ham shack and my network at the ham shack location is linked to my location (through VPN) so that the Windows computer at my location will connect to the KAT-500 serial interface.

4. I do not have access to my P3 operating remotely. Others have installed video cams aimed at their P3 to forward imagery to their location to see what the P3 is displaying. Others who do this may have some thoughts on managing the P3 remotely.

5. Antenna selection is done using an Antenna Genius from 4O3A. There are a total of 8 antenna ports and two radio ports. The K3 system is connected to Port A and communicates with the Elecraft through BCD to select the antenna based upon the band that the K3 is set (e.g. 10-15-20 goes to the tribander, other bands such as 40 and 80 to an EFHW with additional ports for a dummy load and future 6M antenna). The Elecraft interface to the AG is based upon Y-boxes developed by Bob Wilson, N6TV. See: https://www.kkn.net/~n6tv/Y-BOX/ <https://www.kkn.net/~n6tv/Y-BOX/>

Antenna Genius Port B is used by my Flex-6700 Antenna Port ‘1” and associated hardware. The Flex communicates directly with the AG through a CAT5/Local Area Network connection.

I also use the AG utility but it can only run in Windows and works with a remote connection through VPN.

My primary use for the K3 is voice communications, so I have not delved into digital modes (yet). My presumption is that operating digital may require using the PC in the ham shack to do the actual digital operation while connecting to the shack PC via Team Viewer or other remote access software to manage the process. Again, others who are actually doing digital modes while operating remote may have specific suggestions.

Overall, I’ve been very pleased with the K3 setup operating remotely. The Codec(s) used by Remote Rig require very low bandwidth while providing excellent audio. As my station is located in rural SE Georgia where internet access (at best) is typically 768 Kbps upload/20 Mbps download, I have no problems running the K3 remotely while using SSB. While I also enjoy the Flex (particularly since SmartSDR v2 was introduced that allows remote connection), slow internet is better handled by the K3 system because of the Remote Rig audio Codecs and the lack of panadapter/waterfall display that can take up bandwidth.

FWIW,

Barry Baines, WD4ASW

Re: K3: As remote Base

Dave, I've been very successful using a RemoteRig configuration similar to
that described by Barry. Instead of a K3/0-Mini, I have a full K3 at the
control site where I can also operate locally when the suburban QRN
subsides. I use an external CW keyer at the control site and inject keying
into the RRC through a rear-panel connection, documented but non-obvious.
The local monitor in the RRC avoids the confusion caused by latency on the
remote K3's own sidetone. I use KPA500 Remote and KAT500 Remote instead of
the RC-1216 and I'm very happy with their UIs. They and other utilities I
use do require a server computer running at the radio site. I have a remote
power strip so I can power down individual devices. A remotely controlled
relay board controls various accessories. I use PstRotatorAz to control my
rotator and SteppIR beam.

The big and new difference between my config and Barry's is remote
panadapter. I was dissatisfied with a camera facing the P3 as it provided
no access to the P3 controls. But my logging program, N1MM Logger+, now has
a Spectrum Display window that I drive with an inexpensive Airspy HF+ SDR
at the radio site. It not only provides large-screen display and control of
spectrum and waterfall but also integrates with the band map in Logger and
the mouse for click-to-QSY functionality. Click on a callsign or signal
(with smart zero-beating), or click on a gap between signals, and you're
there! I can drive it either from the K3 I.F. Out signal or the K3 RX ANT
IN/OUT loop. Both work great and it has introduced a whole new dimension to
station control.

Internet connection is critical. You don't need high bandwidth but you do
need reliable packet delivery. At first, at the rural location of my
station, this was a problem - lots of snap, crackle, and pops in received
audio. But over time the ISP improved the cable plant and central office
equipment and now I can comfortably operate a contest with very little
evidence that I'm not actually sitting there.

The system integration is a challenging but fun project - don't get
discouraged by the many "moving parts." Get it going one piece at a time
and you'll be very satisfied with the accomplishment and the eventual
result of enjoying a quiet location for the radio while sitting where you
need to be sitting!

Re: K3: As remote Base

It's the I/O RJ45 connector on the back of the 1258, pin 4, that will
key the remote radio, I use it with a Winkey3. Pin 8 it ground, and
while it is documented in a combination of schematic and pin-out
diagram, it is, as Rick says, decidedly non-obvious.
