FYIW. Why would you require tx frequencies? If you are affiliated with a public service entity, e.g volunteer firefighter for Lehigh County you would be provided with the fqs and other technical information needed to access the system. All the specified counties have strict regulations and instructions for transmitting on their systems and 0% tolerance for unauthorized access. I don't know your circumstances which certainly could be legitimate, so just take this response FWIW.
Have to agree with echo on that one. If you are authorized to have your radio programmed for those systems, simply take it to a factory authorized programmer and have them install the frequencies
Taxi...funny! You can get input for CIA, president, FBI, DEA, Secret Service, and PA State Police but I can't get the input freqs for Eastern PA Region (Carbon, Lehigh, Monroe,etc) I'm an EMT and in the military. Amazing!
