Please note that as of July 2020, the 600 MHz wireless frequency band is illegal to operate in within the US and Canada.
While we are no longer exchanging these systems you do have a few options:
• Some countries can still utilize this frequency range, in which you are welcome to sell privately via an international reseller market such as eBay (or similar)
• You can recycle these with your local electronics recycling program
• And if you would like to discuss current replacement systems that meet your needs, we would of course be happy to discuss further.
