Hi Jeff: First, note that 12 meters (along with 60, 30 and 17 meters) will NOT be used for Field Day. Those bands are "off limits" to contests.
But your K2 should work fine there and on 10 just the same. Does this occur with a good dummy load attached? That sounds a LOT like RF feedback. Such feedback is often much worse on higher frequencies. The same basic audio/modulator stages of the K2 are used on *all* bands, so if your audio is good on the lower bands, they are working properly. The other possibility is some sort of instability in the output stages on the higher frequencies. That is quite unusual in Elecraft rigs, but when it happens it is often the result of a poor load at the antenna. Again a dummy load might identify that by making the problem go away. When checking with a dummy load. Be certain you have a good 50 ohm coaxial cable between the rig and the load (it's a good idea to use a different cable). Ron AC7AC -----Original Message----- My K2 sounds fine on all bands on all modes, both TX and RX except for 10 and 12m. On those two bands, RX is fine, but TX sounds horrible on all modes, LSB, USB, and CW. It puts out full power though. Any ideas? I'd really like to use this at field day. Of course 12 and 10 probably won't even be open...
