• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet.

    PAR FM Broadcast Filter with PSR-600

    I was getting fuzzy audio in the background on most 2m ham and 155 mHz police transmissions from a 50,000 watt fm broadcaster around 10 miles away. I bought a PAR fm filter from Grove, and the difference in receive sensitivity has been amazing. The distorted audio has disappeared, and signal...
