I work for a company in the oil and gas industry, in my line of work I need to keep in contact with the various companies that I work with on various pads through out PA, WV, and OH. Some of them have no issue issuing me a radio while others are short on them or just dont want to give them up. I would like to get a radio that I could program fairly easy. I have found the frequencies online for the various companies and this would save a lot of trouble. The little research I have done has left me with some questions 1. I notice the frequencies listed have 3 digits a decimal followed by 5 digits the radios I have come across on amazon specifically only let you program 3 digits a decimal followed by 3 digits. with that said what are my options if any? 2. I am under the understanding that even though the frequencies list are public I will not be able to transmit only listen which is fine just curious if that is true? Lastly if I could be guided in the direction of what I need and where to buy that would be great. Thanks in advance for dealing with my ignorance in this matter.
