Troubleshooting hints
1)
When I apply power to WKUSB I don’t get the initial R sent in sidetone.
This means that
that the WK3 IC is not starting up. If you are running off batteries make sure you have the
battery holder wired connected to the right place and batteries in correctly. Also make
sure the isn’t a missing solder connection on the sidetone speaker or circuitry.
2)
WKUSB won’t key my radio
. First check to make sure your keying cable is wired correctly
and then check to make sure it is plugged into one of the KEY outputs. If you have it
plugged into KEY2, try KEY1 or vice versa.
3)
I get dits or dahs only or the CW output is garbled
. This usually happens when you have
not disabled your transceiver’s internal keyer. You want to enable straight key mode. In
most transceivers this function is controlled by menu selection, check your user manual.
4)
When I plug WKUSB in or install batteries, I get one R in sidetone but nothing else works
after that.
This is a sign that one of the dit or dah paddles is stuck low. Remove the
paddle connector and see if that clears the problem. We have seen cases where a
conductive solder flux (organic core) has not been cleaned off and this causes various
shorts on the board. Give the board good leaning with a water based flux remover if you
used organic core solder.
5)
When I try to run WKUSB from WK3demo I get the error message Attach WK: No Echo
.
This means that the com port selected was a valid one but not the one that WKUSB is
connected to. Recheck your port selection using WKscan.
6)
WKUSB is plugged in but WKscan does not show a com port with a WK device.
This is a
sign that either a USB driver has not been installed or the USB hardware on WKUSB is
not working. It could be a bad USB cable, missed solder connection on the USB
connector, a solder short on the USB connector, or bent pin inside the USB connector.
Note that the USB interface is factory tested before a board is shipped so if it doesn’t
work the places to look for trouble are limited to the connector and cable. It could be that
the USB cable is not fully inserted at either WKUSB or at the PC.
7)
WKUSB has batteries installed but does not respond to pushbuttons when disconnected
from the PC and will not connect to a PC application.
Early versions of WK3 can hang if
they are running on batteries and are disconnected from a PC while connected to a host
application. You can clear the hang by removing and reinstalling the batteries. This issue
was fixed in version 30.10 for the SMT version and 30.60 for the DIP version.
