The trailer now has Air Conditioning and heat provided by money through the Saginaw County office of Emergency Management. The unit is a Dometic 13,500 btu AC with heat pump for colder weather.  The front 12V and florescent lights had to be move forward to provide space the AC unit. The roof was beefed up with steel L supports tied into the existing roof beams and framed with 2x6 lumber to support the inside control unit. A new electric box with circuit breaker was added to support the electrical needs and is connected to a second generator box on the outside to provide power.  Power is provided by a Honda 3000 watt generator.

2022 Update

Two Nino 1200/9600 baud TNC's were added to the Alinco 220 radios to allow for Winlink capabilities.  These replaced the internal boards that were not full KISS compatable.  The TNC's were funded by Covenant Health Care, a local hospital and will be added to other packet locations in the county.
