I thought I had this figured out and solved. That I have not solved it does not surprise me, I'm fairly old and this *has* occurred once or twice before.
Every now and then, generally more "then" than "now," the baseline on my P3 sort of wanders upwards. Sometimes it's on the left, sometimes it is on the right, sometimes [not so often], it's the entire baseline. It goes up maybe 1/3 of the screen [I usually have the waterfall turned off, I can't see it, long story], and it moves around vertically, not fast, but not slow either [being a retired engineer, I like to be precise]. The band noise and signals seem to ignore this, they just appear on the elevated baseline as if they didn't know, which I suspect they don't. If, when this is happening, I place my hand on the top of the P3, the baseline returns to where it should be and stays there like a chastised 4 year old, with about the same attention span. I have grounded the P3 to my single point ground [a wide copper strap along the back of the shelf and "grounded" straight down to the ground], I've moved the rig power supply [FT-1030A] away, and I've shut the KPA500 [about 10 inches underneath] off with no change. I actually don't mind putting my hand on it to fix it, I've banged radios and moved stuff in magic ways for 50+ years to solve problems, but I'm just curious. My P3 is powered from the K3. Has anyone else seen this? I haven't yet tried "hand on side of P3," tonight if the baseline wanders. 73, Fred K6DGW - Northern California Contest Club - CU in the 2011 Cal QSO Party 1-2 Oct 2011 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
