Two Way Radio Communications, Inc. has a 10 channel trunking system in Cumberland, MD, call sign WPRI785. According to Google Maps the transmitter site is approx. 4,000 feet away from your QTH. One of the repeaters is licensed for 461.5875 MHz, 11K2F3E emissions and 250 watts ERP. I would bet that this is what you are hearing. The pulse every two seconds is usually indicative of some LTR type trunking system, usually normal LTR has a pulse about once every 10 seconds and the Passport variant is usually quicker, about 1 to 2 seconds between pulses. 73, Eric KF8YK
