If your Hardware store stocks a simple buzzer or bell, they are the same thing ready to go. Usually run off of 6 or 12 volts, ac or dc.
Why simulate the QRN with a solid-state circuit when the real thing is so easy to produce? Hi! Ron AC7AC -----Original Message----- The standard "circuit" Ten Tec uses to test their noise blankers is a relay wired to open its own coil circuit and then remake. The arcing at the contacts makes a good close by test source for this. 73, Stuart K5KVH _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
