The Portable Post Office is now reasonably

complete and debugged.

I have worked on this for a LONG time. The application is for an organization when all other communications have failed. Examples are EOCs, Served Agencies, companies, shelters, etc. The PPO includes 5 corded phones with long cords, 4 cell phones, 1 long-range phone, 2 relay stations and a PBX. The relay stations allow the cell phones to be used at some distance, or thru walls. The PBX allows all phones to call one another with a 4 digit extension number, rather than a long IP address. An easily-updatable status board is provided that shows who/what/where each telephone is deployed. There is also a dual-band ham radio, which can be called by any phone to provide phone-to- radio connectivity. Long high-gain antennas are provided for the central node for all services. Everything is battery-powered, and chargers are provided for all batteries, including the cell phones. A PC can be plugged in to monitor and control things as needed. Efforts have been made to make the PPO indeed portable, but I would require several helpers to move it. I would like to make a demonstration to the club at some future meeting, but since we don’t know when we will have meeting space, this may be a while. The space will have to be appropriate for the demonstration. The Portable Post Office is housed in several containers. The contents of each container is listed here. Contents of Traincase PBX, WiFi Router, 10 Watt 144/450 Mhz Transceiver, 7 Amp-Hour 12 VDC battery, 5 Cell Phones, Charger for 5 cell phones, 24 Power Pole outlets, Cooling Fan, Interior Lighting, Standard antennas for WiFi and Radio, Battery Volt/Amp meter, Equipment Manuals, 2 Exterior ethernet sockets, Outside 4 conductor plug for radio controller cell phone, and the Interface converter board between the radio and a cell phone. Contents of telephone bag 4 Corded analog telephones with long 12 foot cords, 4 analog to digital telephone converters, 4 telephone 7 foot extension cords, 4 port Ethernet switch, 12 VDC battery charger for heavy loads, 12 VDC battery charger for battery maintenance, Exterior 3 foot ethernet cable to Train Case, Exterior 3 foot 12 VDC cable to Train Case, Exterior 10 foot 120 VAC power cable, Wifi Relay station #2, with 10 foot 120 VAC cord, Long Range Antennas for Wifi and Radio. More contents will be defined in subsequent editions.
