Re: [Elecraft] K3/P3/Microkeyer hookup

[john]

I do not own a Microkeyer but I do have several DigiKeyer II's that I  
use for FSK and CW. My MicroHam cables are clearly marked where to  
plug them into a K3/K3S.  I move my transceivers around a number of  
times a year, the markings have made setup quite easy. If you do not  
have MicroHam cables, making and labeling your homebrew cables as  
shown in this schematic should help:   
https://www.microham.com/Downloads/DB37-EL-K3.pdf . The Elecraft  
manual will show how to add a P3 to the mix.

OM-Power includes TCP/IP support built into the 2000A+ and via an 
optional control head with the other autotune amps. They use Lantronix 
XPort.

Re: [Elecraft] K3+P3+Microkeyer II

[Josh]

Again, that makes no sense. OM Power  supports ELECRAFT directly and provide a 
pair of serial ports for doing so. No Y cable is necessary (and a bad idea). 

This is how OM Power describes using their product. It works fine. You're 
coming up with a workaround for a nonexistent problem.

I know you know this, but others might not -- RS232 is NOT a matched 
system. It uses a low-Z driver and a high-Z receiver. The real issue 
with loading is CAPACITANCE -- later versions of the RS-232 Standard 
reference cable capacitance and baud rate rather than cable length as 
the limit of transmission distance. CAT5/6/7 cables are among the lowest 
capacitance paired cables we can easily buy, and their loss is fairly 
low at RF. CAT5/6/7 cables are four twisted pairs, each with a different 
twist ratio to minimize crosstalk. RS-232 cables wired to use one of 
these pairs for each of the signalling circuits are about as good as it 
gets without spending big bucks. Most ham gear uses only RXD and TXD 
(pins 2 and 3 on a DB9) with pin 5 as return.


My serial cables use two pairs to connect 2 and 3 with both pairs 
returned pin 5, and with the remaining conductors wired to the DB9 
shells. My cables are pretty short, but I've used cables like this that 
are 200 ft long or longer to connect a computer to sound system DSP to 
do system setups at fairly high baud rates.

Re: [Elecraft] K3+P3+Microkeyer II

[Joe Subich, W4TV]

microHAM has provided "cross brand" support for mixing transceivers
and amplifiers for a dozen years or more starting with the original
microHAM Band Decoder.  Icom has been the default interface for
serial (CAT) controls while Yaesu (BCD) has been the default interface
for "Band Data" control.

Since the current OM Power transceivers support Icom interfacing, it
is the obvious choice with microHAM interfaces and has been since the
earliest serial controlled OM Power amplifiers (those that did not
provide for CAT pass-through).  Using the Icom controls is far more
reliable than using a "Y" connection on a RS-232 connection; it avoids
issues with loading RS-232 circuits and the isolated CI-V Transceive
emulation provided by the microHAM interface avoids issues with
collisions/corrupted commands on a shared CI-V bus.

Re: [Elecraft] K3+P3+Microkeyer II

[Josh]

Patch the OM Power between P3 and microham box. TCVR goes to P3 and PC goes to 
microham. Then select Elecraft and baud rate from the menu. You should 
immediately see it following frequency on the display. 

OM Power echoes serial commands through and monitors the data. I don't have 
your model, but this is how they all work. 

Any problems you should contact OM Power support. Tibi is very good and will 
respond quickly.

Re: [Elecraft] K3+P3+Microkeyer II

Don is off base when he talks about a system using a microHAM
product.  Configure your station as shown in the application note
"Using the Icom PW-1"
  
at http://www.microHAM-USA.com/support.html

The connection diagram for microKEYER II is here:
  

You simply configure the amplifier as if it was connected to
an Icom transceiver - that information is generally in the
instruction manual provided by the amplifier manufacturer.

Note: this information applies to *any* frequency agile amplifier
capable of serial control using Icom protocol.  The information
in the application note "Using the Icom PW-1"
  
also covers interfacing of BCD controlled amplifiers - like the
Yaesu FL-7000/Quadra, Elecraft KPA500 (and KPA1500), Ameritron
ALS-600/1300/1306, etc. to transceivers which lack BCD outputs
using microHAM Station Master.

You can add as many Y-adapters as needed to the K3 AUX connector.  In some
of my setups, I have as many as four, due to the number of devices connected
to the AUX signals.  Just be sure you get Y-adapters that have all 15 pins
wired through and none shorted to each other.

Re: [Elecraft] K3 + P3 + Microkeyer

[Joe Subich, W4TV]

The KPA-500 does not figure in the K3+P3+MKII "chain" ... As long as
you have the DB15HD "Y" cable (part of the KPAK3AUX cable set), you
can connect the KPA-500/K3 AUX cable to one leg and the MK II ACC
plug to the other and there will be no issue.

If you use the MK II PA PTT output for amplifier keying, you will want
to include the Elecraft "Key Line Interrupter) between the KPA-500/K3
AUX cable and KPA-500 to block the K3 -> KPA3 key out signal.

Re: [Elecraft] K3 + P3 + Microkeyer

[Joe Subich, W4TV]

I do it that way myself ... each K3 (+P3) has an RS-232 A/B switch on
it.  The computer serial port has an A/B/C/D switch that connects to
each of the A/B switches, the programming cable for the XG3 and for
now the LP-100 (but normally my general purpose test port).

Re: [Elecraft] K3 + P3 + Microkeyer

[Don Wilhelm]

An RS-232 A/B switch can make that changeover easy - the common of the 
A/B switch connects to the K3 (or P3) and one side connects to the 
nicroHam while the other side connects directly to a serial port (or USB 
to serial adapter).  A simple "flip of the switch" changes it from 
normal configuration to Firmware download mode.

Art -
 
You have it right.  
 
In normal use the microHAM unit is in-between the PC and the K3 or if
there is a P3 it is PC - P3 - K3.  BUT when having to do FW update to
the P3 or K3 or screen capture off the P3 the PC needs to be connected
directly to the P3 or K3.

If I remember correctly, microHAM specifically advises *against*
connecting like that and doing updates through the microHAM device. It
would seem prudent to disconnect your microHAM device and directly
connect your P3/K3 combination and effect updates in that manner.

The big cable that you plugged into the back of the microKeyer with all
the
seperate leads you hooked up to the K3 - one of which is the serial
interface (RS232).  Now the communication between the PC and K3 is via
the
microKeyer.  Works fine but for one task...FW updates.

Be sure to note in the manual about not trying to do any firmware
updates in
this configuration.  You MUST plug the K3 directly into the PC for these
updates.  Believe me, as the manual says, it does NOT work with the
microKeyer in the middle.

All information is pretty clear in the MicroHam manual.
