This linux command line is hard!?!

Someone just pinged me with the regular beginner fears of working in a linux environment, especially the command line.    Luckily I found a nice site that gives a good set of introductory command line commands and arguments : 

http://en.wikibooks.org/wiki/Linux_For_Newbies/Command_Line

A few of my personal tips :

1) Use the man pages!    IE: ‘man rm’ will show you all about the rm command and how to operate it.

2) Note everything is not in the path, especially the current directory.    If a command will not run, try doing a ./<command> rather than just <command> if it is in the current directory.

3) / Unix   \ Windows.     The path separators are different.. so if your a windows command line guy.. this will take a bit of getting used to.

2m / 70cm Cheap Antenna Setup

So I removed the temporary Slim Jim stuck on a fishing pole from the side of the shack. It wasn’t a bad solution but certainly wouldn’t hold up to any real weather. More info on the SlimJim can be found here –> n9tax antennas

Being a cheap ham and having spent a lot of money getting the rest of the ham shack together, I didn’t want to break the bank on the permanent solution. So I settled on a Tram Dual Bander which can be found here –> Amazon Link I did take a minute to inspect all the solder joints and put rubber electrical tape covered with shrink wrap tubing over the main joint (just because I am paranoid). At 8 feet and a reasonable gain for ~$50 I figured I didn’t have much to lose.

So the more interesting piece was the mount. I was playing with a lot of ideas from a ROHN pole to some other type of mast. I came across this mount on Amazon and couldn’t resist for $30 : Winegard gable antenna mount This thing is a beast!! Getting it up to the mounting location took a bit of planning. Lesson learned : Attach the top section first, insert the pole between that and the long gable mount and bolt it in… then bolt in the longer gable mount to the wood. I painted it a nice brown that accented the shack fairly well and after a few hours (that included adding some 2x4s to the underside of the gable for support) I was on the air. SWR was fairly flat over the 2 meter and 70 cm bands and was able to hit all my favorite repeaters.
