hello juliano, I'll put the single "080 info" Book of troubleshooting, if it can help you
If you saw the message INFO 080, the I/O controller (IOC, RF-U1) or other auxBus device did not respond to messages from the main processor (MCU). Turn power OFF and back ON; if you hear some relays switching on power-up, the IOC may be OK, and the problem is likely to be with the AuxBus (081) If you do not hear any relays switching on power-up, your IOC (RF-U1) may be defective. Inspect U1 carefully to see if you have installed it backwards or if any pins are bent. Pull U1 out, check its pins, then re-install it, making sure all pins make good contact with the IC socket. Check the 4-MHz oscillator (075). Remove the bottom cover and verify that all pins of U1’s socket are soldered, as well as those of the 6V regulator (RF-U2), and U1’s 4 MHz oscillator (RF-Z5). With power ON, check all voltages associated with U1. You should see 6V at pins 1 and 20 at all times, even when the IOC is sleeping (not being accessed by the MCU).

I now have K1, K2 and K3 + P3. The K2 serial number is very low and I think some changes are essential and others less so. Can anyone tell me what mods are the really important? I also have a problem that occurs very frequently: when I change band +/-, very often comes out "INFO 080". What can I do? Thanks for the help I0CG Italy ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to f8ac...@yahoo.fr ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
