Re: [Elecraft] Upgrading a K3?

Yup, that was me. The Radio Shack portable mat in particular is one that my testing showed to have too high a resistance to do any good. The one Walter mentions (below) is probably OK. The Amazon page specifies "Surface resistivity: 10E9 - 10E11 Ohm/m2" and it mentions that the back side is

For data modes (PSK-32, FT-8, etc.) you don't need to move the radio. Raspbian supports VNC natively. There are VNC clients for just about every operating system including Android and Windows. Sit in the living room with your laptop or tablet, jump across your network using VNC to get to

Re: [Elecraft] AUXBUS Troubleshooting

Karin, Jack makes a very valid point. If you are not using the K2 to PC special cable to the AUX IO connector that removes all but TXD, RXD and SIGNAL GROUND from the RS-232 cable, the K2 may display "strange happenings" or in the worst case can cause damage to both the K2 and serial port.

Re: [Elecraft] AUXBUS Troubleshooting

The auxbus is activated briefly on band changes to update transverters and the KRC2, whether present or not. It’s possible that during auxbus activation, the K2 may be missing an RS232 character or two. (Interrupts are locked out.) I’d have to dig into the K2 code to determine this. The

When working on tube gear, keep one hand in your pocket. When working on solid-state gear, keep one hand on the chassis. But a static mat is cheap insurance for when you need to scratch your nose. Amazon has one for $11. I think I paid more for mine at Fry’s, but whatever.
