Unfortunately, no, we do not provide that service. Part of the value in purchasing from shielded signals is knowing that you will get equipment that we know and understand, and that provides interoperability with other shielded signal subscribers if needed or desired. our equipment provides robust encryption, and even if we sell radios from more than one manufacturer, you can be assured that all of our radios will be compatible with each other.

We are starting small on purpose. We had an idea and we wanted to see how much interest we could generate before expanding further.

we plan to provide more coverage in iowa as our number of subscribers grows. if interest is high enough, we will also investigate the possibility of installing repeaters in key locations to further enhance coverage.

Our 6 “standard” channels are assigned to shielded signals for our exclusive use. there are no other entities in the state of iowa authorized to use those 6 channels. the statewide channels are considered “itinerant” channels. They are available for use by multiple companies on an ad-hoc basis. chances are that you will never hear anyone else on the statewide channels who is not a shielded signal subscriber. however, if you do, they are very likely assigned that same channel for their company, and we cannot claim interference. Everyone plays together on those channels.

absolutely! when you purchase your radios from us, they are yours to keep. we provide the programming to use our frequencies and encryption, but they are still your radios. However - if you no longer subscribe to shielded signals, you lose your authorization to legally use our assigned frequencies. you will also not be able to change the programming in your radios on your own, as access to programming features are locked out. but if you return the radio to us, we will remove the programming and ship it back to you, with all of our programming removed.

if your equipment is in good shape, we may be interested in purchasing it from you. we reserve the right to accept or deny any offer to buy back equipment you purchased.
