My K1 (sn2450) went together back in Oct 07 without a hitch and has been working flawlessly ever since.
A big glitch showed up tonight.? When I pushed the attenuator button it started transmitting dashes.? That cleared by cycling the power.? I then tried sending the content of memory 1.? It began sending that message, stopped, "end" appeared in the display, then started transmitting alternating dots and dashes.? When locked in transmit, the display blanks out.? Initially I verified that it was transmitting with another receiver, but now it seems to have lost output too.? It was hooked up to a resonant antenna or dummy load, so I wouldn't think the final fried.? I'm running it off a supply at 13.6VDC.? A voltage check of RA3 pin 5 of the MCU shows 5.6V with both dot and dash contacts open.? When the WPM-/attn button is held the dashes start sending and the pin 5 voltage drops to 5.0 even? though the contacts are still open. I've been awake too long and not much is making sense, so I'm going to call it a night.? Any ideas or suggestions on where to look would be greatly appreciated. Chuck?
