When I was around the same age, my Father bought the 3-transistor regenerative Short-Wave Radio Kit. A listing of the P-Box kits can be found here: http://my.core.com/~sparktron/pbox.html My Father was a Fireman, so there was no way he would trust me with a soldering iron at such a young age. Instead, he ended up building the kit himself while I watched with great interest. He wound several coils so the receiver could receive several ham bands as he was trying to spark an interest in Amateur Radio, but I don't ever recall hearing any hams with the receiver, just the typical short-wave broadcasts of the time. Several years later, he ended up taking the receiver away from me because the radiated broadband noise interfered with his Swan 500CX. :-) It didn't matter much to me anyway as I never heard much with it. But it was every educational in the sense that the frequency range of the receiver was dictated by the size of the coil wound by the builder. Eventually he gave me his old Hammarlund HQ-140-X, so I hardly ever missed that old Radio Shack regen. Interestingly enough, there's a modernized version of the receiver that employs silicon transistors (2N3904 and 2N3906s) instead of the original germanium jobs. Details can be found here: http://www.netzener.net/images/swradio/swradio.pdf And that old Hammarlund lives on to this day after I "solid-stated it" not long after becoming a ham 40 years ago. 73 de John, KD2BD ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
