Re: S-85 refurbish: I've got a problem during the RF alignment of bands 1 and 2 - trimcaps don't peak!
¿ªÔÆÌåÓýNick you are a joker..hi-hi,? as shown, L6 never gets any signal from the left but is connected to the caps and tube as expected at the right.. That switch looks clear enough on the drawing. ?Maybe the drawing has some UV components and wires? I am looking on the BAMA pdf doc.?? maybe the paper wore thin? ?

So the same would be true for L6... ? Also, I wonder if under some circumstances (~1/2w antenna) shorting out that 1k resistor would improve Band 1 performance.? Seems like it would be a voltage divider the way it's configured in the schematic.? Unless maybe it was intentional attenuation to stop broadcast band overload in urban areas? _._,_._,_ -- don??? va3drl |
