Re: [Elecraft] K3 - remote control head

[Jim Brown]

:

The K3/0 should allow you to control a K3 over a RS232 connection,
which could be a fairly long cable (up to 50 feet, perhaps?),


Another very useful fact -- RS232 uses an unbalanced connection, and the 
connection is NOT impedance-matched.  That is, the source has a low 
source impedance and the receiver has a high input impedance, so the 
interconnecting cable appears as a capacitive load to the driving 
source. A decade or so ago, we often used RS232 for the connection 
between a computer in the audience in a large performance space to 
signal processing equipment buried in the bowels of the building. We 
were able to reliably use runs on the order of 200 ft at decent speeds 
by using CAT5 cable for the connection, using a pair for each signalling 
circuit, by dedicating all un-used conductors to the return, and 
connecting the returns to the SHELL of the DB9 connectors at both ends. 
It works because CAT5 cable has good bandwidth AND low capacitance 
between the conductors of a pair, the twisted pair rejects noise, 
connecting to the shells at both ends gets around Pin One Problems that 
may be present, and doubling up on the return conductors minimizes the 
IR drop from AC power leakage currents that may be present because the 
equipment is powered (and perhaps grounded) at widely separated points.


Another method to consider for longer runs is RS422, the BALANCED 
configuration of the serial interface.  A very good company in Illinois 
called B&B makes very nice, fairly inexpensive RS232 to RS422 
converters.

The K3/0 should allow you to control a K3 over a RS232 connection,

cables, and probably a wall-wart by the recliner).

I doubt that there will ever be a blank front-panel option for the K3.
The K3/0 (mini) does not replace the functionality of the "real" front
panel. I suppose there could be a version with no
display/buttons/knobs, but it seems unlikely that that would be worth
the development effort...

Re: [Elecraft] K3 - remote control head

[iain macdonnell - N6ML]

It should be technically feasible to use the "high-speed" protocol
that was developed for the RemoteRig solution to implement a remote
control head that talks over a serial connection to the K3. It'd
essentially be a K3/0 in a compact package, suitable for moving around
the desk, or mounting on a vehicle dashboard. The RR boxes wouldn't be
necessary for such short distances - just RS232 (although it'd need to
get power from somewhere too).

Re: [Elecraft] K3 - Remote Control Head

[Charles Sanders]

If what you are looking for is a multi-function remote tuning knob consider
using the Shuttle Pro 2 by Contour Design at
http://retail.contourdesign.com/

I've used this device in that role in my mobile contesting setup to control
the K3 which is in the rear of the vehicle and the operator is in the front
passenger seat. The Shuttle Prov 2 has a nice set of 15 buttons and a
tuning knob. The buttons on the Shuttle Pro can be mapped to any function
keys supported by the software you are using and also supports macros which
combine multiple function keys. There is a brief description on this page
of my website http://www.no5w.com/CQxK3RemoteKit.html describing how I am
using it with CQ/X.

Of course the above approach requires an intermediary in the form of
software running on a PC. If what you are interested in is a standalone
remote that connects (essentially) directly to the K3, an Android
smartphone can serve as the display and controlling device and can be
interfaced wirelessly to the K3 over Bluetooth via a small PIC-based board
(Android IOIO) from SparkFun Electronics https://www.sparkfun.com. Some
details of the interface and of a prototype are available at
http://www.no5w.com/CQxK3-AndroidInterface.html. It should be noted that
this is a work in progress. I believe there are others who have carried
this idea even further so look around and see what you can find.

Re: [Elecraft] K3 - remote control head

Mark,
Yes the remoting capabilities are great but a simple pod such as TenTec
uses is what some of us would like.   A good friend EI9KF is using a K3/0
with similar interface boxes and it is a pretty nifty arrangement.

Thanks.

Re: [Elecraft] K3 - remote control head

Bill,
 I wonder if the Elecraft K3 has the I/O signals to easily implement a
remote head.  This is a feature which has been requested in the past and I
think that Elecraft even had a prototype at one time but it died a death -
could be wrong on this last point.I too have hoped for this feature as
implemented with the Orion II but Elecraft has supplied so much it is
churlish for me to look for more.God, an improved AGC for CW, P3 SVGA
adapted for data modes - it is hard to keep up with Elecraft.They are
such an unusual company in their close links to the customer base and
willingness to oblige when they can.   We are a fortunate bunch to have
chosen their product.

 The hot keys software is supposed to implement some of what I want in a
remote control head but the confession is that I have not tried this yet.
Interaction with Micro keyer II or Wintest is my worry but I understand this
is not supposed to be a problem.

No big box behind the panel, just a line to the transceiver - which is

very handy to be able to move that control panel all over my desk. This 
is similar to the Yaesu 857D and the Icom 706 and 7000 series.

It is not rocket science - just another purchase for the K3.
