Mobilinkd is still open for business during the COVID-19 pandemic.
While the state of Illinois is on lockdown, we are a home-based
business. We will continue to accept orders as long as the postal
service continues to accept packages. USPS is reporting service

The TNC3 is a 1200/9600 baud KISS TNC.
