    Sirio mobile antennas, which is which

    I've been thinking about mounting a roof mount sirio antenna on one of my vehicles. I like the size of the base and I like the fact that they have their own internal matching device so they do tend to tune very well. I have not been impressed with the quality of Wilson's in recent years. All...

    What's inside the yaesu 101 filters?

    Even though the yaesu 101 is an ancient radio by today's standards they still get used, traded, and sold. In fact, I'd argue they are an easier sell when they are in working order than loads of their more modern counterparts. There are a handful of places that still repair them as well which is...

I have seen mention on various electronic forums and I think this one as well, a technique of using the secondary of a second transformer, just the secondary I think, in series (I think) with the primary of a high voltage transformer...

    List of radios that have a TVI trap

    So from what I can see any type accepted cb like a cobra or uniden has a TVI trap built into the final circuit. Does anyone have a list of radios that do NOT have a c TVI trap circuit? I can only assume all 10m exports do not, what about their cb cousins like the galaxy 959 and similar...
