Hi everyone, [snip] Thanks to everyone for the great and helpful suggestions. This sure is a friendly group. Since I just recently started all this tinkering, my junkbox is a little low in some areas, notably NP0 capacitors.. I have a few in values from 3.9 up to 47 and a few 100s but not else. So I've used various other types when higher values are called for.. I'm planning on picking up an assortment soon. Also I have some copper clad non drilled pc boards, I'm going to try to rebuild the oscillator (and radio) using the 'ugly' method; although I'm a little afraid I'll make myself a tangled mess of useless and stuck together parts. The main reason I use breadboards is so that I can take parts in and out of the circuit quickly (ie I'm at the stage where I'm curious about what happens when I take such and such part out, or change its value etc). I'd love to get a oscilloscope but my 'play' budget is mostly spent for awhile. So I've been making due with an LCR and a little cheapo DMM. I did order the book _Experimental Methods in RF Design_ .. I've also got a lot of good info from an old (well 1998) ARRL handbook I got on Ebay. Jock |
