This was a unit ordered from amazon. I intend to use it with a KX3
I followed the instructions to cut the two traces to the CMOS pads, and then added 3 solder bridges on the RS-232 side.
Multimeter confirms the 2 traces that needed to be cut have been. Also there is no bridging between the 3 RS-232 solder blobs.
I took the digirg and hooked it up to my kx3, and the PC could not communicate with the radio. I confirmed with the factory elecraft USB-> serial that the rig was able to communicate.
Back to the bench for a bit more testing. If I hold the digirig so the digirig text is right side up:
I have continuity from the top rs-232 blob to the bottom right cmos pad. 33 Ohms
The diode beep / continuity from the bottom rs-232 blob to the bottom right cmos pad does not show continuity, but I have 42k ohms between the pads.
Thoughts on what to check next?
