[Elecraft] MICROHAM USB III INTERFACE WITH K3 UTILITY DOES NOT WORK

[Tom]

Hi,
I may be mistaken with the following. Joe can answer this best.  Using the 
K3 utility with the MicroHam, is not something you generally want to do. 
Many of the commands are not part of the Elecraft serial port API.
I know that in the past when Win4K3Suite was being developed, the MicroHam 
would not pass P3 commands and Joe was kind enough to add these commands to 
the router firmware.  Now in the case of the K3 Utility, many of the 
commands are not published and therefore might not be passable through the 
serial port.
Use of the K3 utility though any software router is not recommended and you 
might brick your K3.

That being said, VMWare fusion will pass all USB ports through to the 
Windows 7 virtual machine.  You must first plug them into the Mac OS and 
make sure they work there.  Then you start up your virtual machine and make 
sure you have enabled and connected the USB devices in the VMWare settings 
(I think there is a tab on the top to do so.)  If this is not done, then no 
ports are available.
Hope that helps.

Greg,

Do you have a USB to serial cable other than the MicroHam?

If so, try connecting using K3 Utility with it.  If it works, then you
will know the K3 is OK, and the computer (at least for K3 Utility) is OK
too.
If that is the case, then you will only need to look at the MicroHam,
the serial cable from the Microham to the K3 and the cable between the
computer and Microham.

That is a lot better than trying to troubleshoot the entire system
(computer, Microham and K3) as a single unit - in other words, isolate
the problem to one box and its connecting cables.

Set the baud rate for the COM port at 38400.
