I've found that a lot of sticky things, including sticker glue, is oil soluble. So I just use a liberal amount of vegetable oil with a cloth to dissolve the stuff and get rid of the goop. Then you are left with an oily surface (you probably shouldn't use this method on cloth which might be

Hi Bob It's certainly very much from the same family, these seem to be a couple of years more recent but obviously aimed at the same spec, and I don't doubt they're going to behave in basically the same way, but given that such things are firmware driven that doesn't exclude possible

Hi Charles Thanks for your comments, the surveyed position on this is looking pretty good but what I have now realised is that the severity of the jumps seems very much related to the number of sattelites being tracked. Switching from 8 to 7, or 7 to 8, sats seems to produce the biggest

Hi You may have your elevation mask set to low for your antenna or a multi path issue from some other source. If the survey location is good to under a meter and the signals are good, there should be very little shift as sats are picked up or dropped. Bob On Aug 1, 2013, at 5:09 AM,

all crystals would have been subject to X-rays to some extent because this was how the planes were located and the cutting angles determined. The dose rate was probably quite low in this case.I dont remember seeing much protection around the machine in the lab I worked in. Alan G3NYK

Hi The only known impact of radiation on quartz crystals is to move impurities around in the lattice. That's going to be a bad thing. There have been many papers on this. If you want to dig into them, digging into a good index of the FCS proceedings is a good starting point. The crystals shown
