Hi everyone! I bought a tiny tuner circuit board off of E-bay for a kitchen sound system. This one:"DSP & PLL Digital Stereo FM Radio Receiver Module 87-108MHz with Serial Control". $7.29 plus shipping. I am powering it from a 9 volt battery and an LM 7805 regulator to get 5 volts. It feeds a mini chip amp from Parts Express. Quite amazing for its size and price. I have a question about the antenna. It has only one hole for an antenna wire. The "documentation" says to use a wire about 75 cm with it. Is this a "tuned" length or is the wire length arbitrary? Is longer better? Should I be using NOS Western Electric telephone wire recovered from Area 51 and treated with ground diamond dust and ferret urine? ;) What do you think?
