Hi Dave, A "via" is a small hole in the circuit board used to connect traces from the top side of the board to the bottom. There's a small hollow metal insert in them that connects the two sides of the board (called "plated through vias") They're usually smaller than a typical component mounting hole.
If you look at the picture in the instructions, the closeup on the right shows a via (the small hole) just to the left of R8. In the picture on the left hand side, it shows the little 1/8 watt resistor with one lead going through that hole. The little white plastic thing in the kit contains a surface mount resistor you can use to replace R8 with if you can do SMD soldering. If you don't have have a fine tipped soldering iron, steady hands, and a good magnifying headset, you can use the 1/8 watt leaded resistor instead. The mod gives you 10 dB more signal at the IF output connector on the KXV3. This is useful if you want to use a panadaptor (such as the P3) with your rig. It won't make any difference in what you hear through your headphones. 73 -- Joe KB8AP On Mar 1, 2010, at 8:49 PM, dbellw...@aol.com wrote: > So I see how to attach it but have no idea what a "via" is? > ... > And for that matter, what is the purpose of this modification? ... > 73, Dave > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
