I bought a big (4 foot wide x 2 feet high) curved high-gain directional antenna (like you see at TF&R stations) AND I still can't get a reliable signal to decode LC/NWORPS system on my POS PRO-96 scanner. I tried aiming it one direction, checking decode (get 53%, 80%, 0%, 33% etc) and then move it about 15 degrees and try again. Still no consistent, not even half, of the calls decoded.
Should I try horizontal polarization instead of vertical? I'm in West Toledo, and I thought my best bet is to ONLY get the Station 18 tower or Flower Hospital tower? Very frustrating all that I've tried in order to try and get a simple APCO25 CQPSK system to decode within the city limits. Ready to throw the scanner off the roof...
