Some time ago I realized that I could make a multiband vertical by simply taking half of my 80/40 meter trap dipole and turning it on end. There is another way to do this by using a tapped, switched, loading coil at the base. I recently saw a design that covered four bands with a 27 foot [...] Want to make some potato chips? I guess the million dollar question is why? So much easier to buy them. True, but if you don’t want or can’t go to the store right now, here is a way to get your chips without leaving the house. Of course you will need to already [...] After kicking this subject around for decades, I have finally decided on the best solution for my purposes. I already have a multiband beam which covers 20, 15, and 10 meters. All I really need now is a multiband dipole (inverted-vee) for 80, 75, 40, and 30 meters. Since I already have the 40 meter [...] If you are sufficiently computer literate to get on the internet, you probably already know what firewalls are supposed to do and why they are called firewalls. However you may not understand how they are best installed and used. I often hear the computer novice claim that his router has a firewall that is fully [...] Well, it is official now. I never thought I would see this day. For some reason a 20 year period in the 60’s seems to be much longer than the same period in todays time. I am not sure why the long, dim, past appears expanded while the more recent past [...] I have finally become convinced that what you hear, read, see on any media source could very well be misleading, in error, or complete nonsense. This is especially true if the tale is full of emotion eliciting details and/or lacking those details. Some of these attempts at deception indict themselves. For instance, any story that begins [...] Phase Shift Keying, thirty-one style, came out some time ago. Shortly after it appeared, I began using it. The requirements were PCs running DOS or Windows and using sound cards as a poor mans dsp. One application I had used a real dsp. A TI 50dsp thing that used a DOS [...] Over the years I have had a variety of communications equipment. Some of the gear was all tube type, other gear was all solid state. There has always been some controversy regarding performance when tube gear is compared to solid state. Tube gear is supposed to have a much better signal to noise ratio [...] It was working so well too. I have been using Debian Etch now for a number of weeks. Recently I decided to load it onto an additional two computers. I used the same netinstall CD I had used for a prior install but the install failed. The failure was an Xwindows server problem. [...] Several months ago my son-in-law presented me with a 128mb flash memory device. The idea is to plug it in to a usb port and instantly get 128mb of quick, removeable, storage. 128mb is not really large enough to serve as a system device , but it is plenty to turn a marginal 64mb, memory [...] |
