  The repeater cabinet next to the duplexers. |
 Close-up of the duplexers. The green bottle in the background is empty, but usually holds nitrogen to pressurize the hardline coax and keep water from getting in it. |

W5AC-2 Digipeater This is our whole digipeater setup, converted from a RoseNET node that had fallen into disuse. At the bottom level is the power supply: unknown brand, but it makes a nice, loud hum. Above that is the laptop, donated by a club member, running Digi-Ned software on SuSE Linux 8.1. Next is the TNC. Simple little MFJ-1270B with TAPR 1.19 firmware in KISS mode. Up top is the radio, a 2m mobile. 5 Watts out right now until we solve the slightly-higher-than-wanted SWR. |
Comms closet This is the communication and networking closet that houses our digi. We're not sure how much of that wiring is still in use. You can also see the orange fiber-optic cable coming into the closet. It's main- tained by Texas A&M's CIS department and is currently off limits for us. |
Not pictured - Dangers of radio work Those shelves in the digi case are sharp! Look out. | |
