When you purchase TvXplorer directly from this site: www.redzonereceiver.tv an account is automatically created for you. If you purchased TvXplorer or RedZone Receiver through one of our re-sellers, contact us with your first and last name, your business email and license key and we’ll get right back to you with a solution.
You can either over-install Tvxplorer, or you can un-install TvXplorer and then re-install it on another PC. Be sure you are connected to the internet when you un-install as the license key needs server-side activation.

We recommend Intel based PC’s with a Core i5 or better CPU.
If you are going to be capturing recordings make sure the hard drive or SSD storage is adequate. We recommend 1TB of storage, or two separate hard drives.
Machines with 8GB of RAM should be adequate but we recommend 16GB to be more future proof.
Microsoft Surface tablets are small and portable but the small screen provides limited screen real estate and is difficult to see the wide array of information in TvXplorer windows.
Larger & higher resolution screens make operation with TvXplorer much easier at the cost of a larger heavier machine. We have had good luck with Dell and Lenovo HDR screens, but would not limit the choice.

Airwavz RedZone Receiver can access any frequency 50 MHz to 1 GHz, and cover just beyond TV Channel 83.
All of Airwavz television receivers support 50 MHz to 1000 MHz (up to 1GHz), in the full VHF and UHF spectrum.
Over-the-air television channels are divided into two bands: the VHF band which comprises channels 2 through 13 and occupies frequencies between 54 and 216 MHz, and the UHF band, which comprises channels 14 through 51 and occupies frequencies between 470 and 700 MHz. These bands are different enough in frequency that they often require separate antennas to receive, but the RedZone Receiver covers the entire VHF and UHF TV bands.
The VHF band is further divided into two frequency ranges: VHF low band (Band I) between 54 and 88 MHz, containing channels 2 through 6, and VHF high band (Band III) between 174 and 216 MHz, containing channels 7 through 13. The wide spacing between these frequency bands is responsible for the complicated design of rooftop TV antennas. The UHF band has higher noise and greater attenuation, so higher gain antennas are often required for UHF.
No. We currently only support Windows Operating Systems 10 and 11
