Hi All, I have a problem with my K3/100 #282. Background:I use Mixw for cw/digimodes.Last week I lost com port,could get it back only by reseating the usb connector on the laptop.Had to do this every operating session.Did'nt matter if I switched on the laptop first or K3. On 22/06 night I switched off after operating as usual.Switched on 23/06 morning. The K3 came on in transmit mode.Switched off power waited for some time,switched on,again came on in Xmit mode.Switched off again,removed rs232 connection, switched on to find same status.Did a forced start with ON button for 10sec's.VFO A shows frequency..
1.On to K3 utility.Comm.established with K3. "K3 boot loader is ready for MCU firmware load"shown. 2.F/W available shown latest regular release,installed is blank. 3.Tried loading,MCU firmware load fails on address x800. 4.Tried steps 1 to 3 on pc with real serial port with appropriate port change.Observation same as above. Going through Elecraft reflector,there is a reference made to U1 snag.This ic is located on the board which accepts on-board speaker connection.Looking at the ic,changing this alone is beyond my capability. 23/06 evening.With K3 connected to real serial port on pc.K3 utility is on and the polling process is not showing any signs of stopping,keeps on toggling through all the speeds. Have written to support at Elecraft. lMaybe they are all busy in DL. 73 de Nandu.
