K2 KIO2 Problem. A few days ago we had a power fluctuation in our neighborhood. The surge protector and Battery Backup UPS did not help. The Power surge took out my computer hard drive, serial interface card and it would appear had some affect on my KIO2.
The KIO2 still works with my KAT-100 and KPA 100 Change Bands and Tune, but I cannot make any connection with the computer serial interface card. I have run the Serial interface Test several times. Of course I replaced the serial card and hard drive, I even switched computers, NO JOY. I have checked all of the voltages on the KIO2 interface. The voltages on the J2, Q1, U2 all match the manual. The diodes (D1, D2 and D3) seem okay but I don't get an exact match with the manual. The voltages on the U1 and J1 don't match the trouble shooting instructions; U1-1 13.6 VDC U1-2 0 VDC U1-3 0 VDC U1-4 0 VDC U1-5 0VDC U1-6 0VDC U1-7 0VDC U1-8 9VDC U1-9 0VDC U1-10 0VDC U1-11 4.9 VDC U1-12 5 VDC U1-13 4.9 VDC U1-14 0VDC U1-15 5 VDC U1-16 5VDC J1-1 0VDC J1-2 -6 VDC J1-3 0VDC J1-4 OVDC J1-5 0VDC J1-6 5.5 VDC J1-7 0VDC J1-8 14VDC J1-9 8VDC Comments, suggestions would be appreciated 73 K2CG Chuck Gehring P.S. I really feel so lucky to have an Elecraft K2. A friend of mine has a IC-756PROIII, He got hit with a voltage spike last month and after several hundred dollars for replacement boards he still has to send his entire rig back the service center. I am very close to talking him in to buying a K2. At least that way he will have a Back-up rig for his K2 when the Icom gets back. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
