Dear Russell: Re: Modifications to a Simple Radio, June '12, page 24, Figure 2. I have four questions since I am not an RF guy: 1. C1: How long can the antenna be? 2. C2: Is its value 0-59 pF? 3. Can L3 and L4 be put on the same diameter plastic bottle if they are spaced 1" from each other? 4. Can any amplifier be used if connected to the right of C4? I have a spare NE386 amp.
