Howdy Dave, Via's are holes in the circuit board that are plated through the board to the other side. Don't ask me why they are call via's ;o) The purpose of the mod is to increase the signal output at the IF Out connector that you would connect a Panadapter to. Some Panadapter need a little stronger signal from the K3 to enable you to see weak signals in the Panadapter display. If you're not using a Panadapter you don't need to do the modification. If that doesn't clear it up for you send me email off the list and I'll try to help you. 73, Tom, N5GE K3 #806 with SUB RX, PR6, KRC2 and K144XV K3 #1055 with PR6 and XV432 W1, 2 W2's and other small kits http://www.n5ge.com http://www.swotrc.net ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
