Event 9 it patched with 155.475 (police national) for the Lance Armstrong bike race. PSP units using 155.475, everybody else on Event 9.
The DTMF tones are coming from Berks County's 155.475 transmitter. The DTMF occurs at the end of their morse code transmissions. It would be nice if neither of things came across the channel...no idea why Berks does this.
