[R-390] PIN Diode Update

[Perry Sandeen]

GM List,

Thanks to the help of Andy Masters, Collin N4TUA, and Bob Camp I may have come up with some reasonable cost PIN diodes.  Bob said that a lot of what's on the market these days has a fairly small minority carrier lifetime which is OK for VHF but not HF.  I don’t know how to select what would work for my VLF loop.  Amplification of information appreciated.

Below is a list of what I was able to find on the WWW.  Someone will have to tell me what will work.  I was looking for affordable  prices as I wanted to use 10 for my loop.

Sources for Motorola MPN3404 PIN Diode.  Prices were from 25 cents to $1 each
