[ARC5] BC-230 first run

    I just posted an explaination with photos 30 mins ago but it had not been reflected.  Will check when I get home since I've been called out to the wilderness for the railroad again ;-)

The soldered tap is obviously factoryinstalled and is about two-thirds the way up the coil, counting fromthe socket end, which is the 'earthy' end.> Actually, the schematic that Neil sent shows the variable tap on> the coil which goes to the antenna, but does NOT show the fixed> tap that Neil was talking about...unless I'm looking at the wrong> schematic....The situation is as you describe it.I've just now checked the wiring, and there is no doubt that the fixedtap connects to the final tank variable capacitor - and to nothing else.In the manual, the transmitter's schematic does in fact show the tap,with the unused portion of the winding shown as a single loop.So, was this outer winding and its former simply a stock item thatwas used for other frequency ranges, or was there some reason fortapping the capacitor down the winding?I guess we'll never know.73 de Neil ZL1ANM______________________________________________________________ARC5 mailing listHome: http://mailman.qth.net/mailman/listinfo/arc5Help: http://mailman.qth.net/mmfaq.htmPost: mailto:ARC5 at mailman.qth.netThis list hosted by: http://www.qsl.netPlease help support this email list: http://www.qsl.net/donate.html
