Joe,Did you check the RS232 cable? Use the RS-232 Break-Out-Box (if avaliable) to see the serial port activity (especially on lines 2 and 3) Can you control the radio by, say, TRlog or TR4W? If not, check the K3 schematics and find where the COM port lines are going. The problem could be there.73, Vic US5WE/K1WE K3 #2907 --- On Mon, 7/6/09, jmalloy <jmal...@hamilton.edu> wrote:

Neither the Prolific USB-serial nor real com ports -- and three different computers! -- make any difference. I think it's a problem with the K3 itself. 73, Joe, W2RBA Don Wilhelm wrote: > Joe, > > Have you tried the steps in the "Forcing a Firmware Download" on page 44 > of the K3 manual? > Before doing that, how about closing K3 Utility and reboot the computer > - sometimes that alone works wonders at cleaning things up. > > 73, > Don W3FPR > > Joe Malloy wrote: >> Hi, Matt, I'm not using a USB hub, my system used to work with a >> straight cable from a com port to the K3 or with the Elecraft/Prolific >> USB to rs-232 cable but no go, no matter which of four port I have.
