If you are curious, there is a thing called the MUF. Short for Maximum Usable Frequency. Different atmospheric conditions cause it to go higher/lower or stay normal. There are situations where you can have a pipe line to some place, usually a one hop skip. Sometimes it will double hop or more and sometimes you can talk to Australia by pointing a beam antenna the opposite direction from them. It is called long path. I have done it once or twice. Longest communication I have had is McMurdo Station, Antartica on 100 watts, if I remember correctly. I talked to the diesel mechanic there who said it was 84 degrees below zero with a wind chill that made it a hundred and some. He told me that they serviced their equipment, changed oil, filter and fuel filters and anything else that looked like it needed it. He tightened up the dozer tracks and run it back out. And the way I understand it, sit there running till another 30 days when they done the same thing over again. He said his helper came in and told him he better look at the dozer tracks, too tight, might break something. He had just got down there and wasn't used to the temperature expansion/contraction thing at those temps. He said he was ready to come home and had just gotten down there. Must be the money???? This can make us feel a little better about our low/rough temperatures. ohfred (KE8SS)

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
