[dorkbotsea-blabber] Pirate radio info

[Steve Safarik]

The late 90's saw a flurry of pirate radio activity in Seattle and elsewhere in the country, with several local groups broadcasting.  Two of them were Free Seattle Radio at 87.9, and Central Seattle Grassroots Radio at 99.5, but there were a number of others also.  I helped with a bunch of the engineering on these, and one of the main issues is what frequency to use (87.9 being the best overall, but a few others too depending on your location).  The other issue is that of frequency stability.  You want to use a PLL type of transmitter as it will not drift at all (as opposed to a VCO which moves around, often onto another station), and you want a low-pass filter between the transmitter and the antenna (many xmtrs have this built-in).  There are a number of transmitter brands & models, but the best in my opinion is the PLL Pro-3 from nrgkits.co.uk (http://www.nrgkits.co.uk/cart_new/contents/en-uk/p3.html), and comes in kit or preassembled form.  

Eventually the FCC came knocking, but it was nice for a few years at least to have some alternative news & political commentary on the radio, and maybe it'll pick up again.

Steve.
