John, I cannot understand (with the data you have provided) how the K1 could be causing something like that. Can you hear it with the antenna disconnected? If so it is a source outside the K1. If it persists with no antenna, the next step is to check the power source - power it from a battery (an automotive battery with the vehicle not running is perfect if there is no alternative). If it is still present with the battery, and with no antenna, you could conclude that it is being produced in the K1. If it is external to the K1, there is likely not much you can do about it in a vacation situation.
There are noise sources that are frequency limited (just due to the physics of the source), and they could actually be harmonics. Do they appear at only one frequency on the band, or are there multiples per band? If only one spike per band, what are the frequencies for each band? 73, Don W3FPR On 9/27/2011 5:25 PM, john Wiener wrote: > I am on vacation and using my K1.
