OK, there is more to this story.? This was a functioning QCX,? but it had firmware version 1.00g.? I in my infinite wisdom decided to upgrade the firmware my self rather than just buy the chip.......oops LOL
I get all the cables, down load the software plug it all in and press the button..... I believe I should have not been powering the radio when I pushed the button.....Anyway, afterwards,? the chip did not update and the screen,? while it lights up still displays nothing.? I have since ordered a new chip.? Which has been delivered and installed.? Alas, the same issue? is still present,? The display lights up (Backlight?) but nothing is displayed.? Regardless of the contrast adjustment. ?? When I plug in my earphones I do hear hiss,? so I think? it is receiving?? but I do not hear anything but hiss.? since I can not see to tune the radio I am not sure that it is actually receiving....Any suggestions?? I did check pin 3 and the pot does adjust the contrast between 0 and 5V.
Thoughts on where should I look?
