Build

Develop/Test

Maintenance/Modifications

• Inventory existing radio and TNC stock. Once inventoried, modify to ham bands. Mark each radio with center frequency and maximum power output. 7/08/10 Radios and TNCs inventory completed, begin modifications/tuning next.

Sites

• Ashland - Online

• Columbus/Battelle - Had to be removed due to personel changes at Battelle

• Columbus/Lincoln Tower - Parking for now

• Johnstown - Online, replaced computer with 1U compaq server, seems to hold up in heat better.

• Lancaster/Firestation #1 - Online

• Lancaster/FMC - Online, installed Polyphaser on V2000, grounded packet and echolink computers.

• Lancaster/WW Hill - Online, installed Polyphaser on V2000

• Mechanicsburg - Offline, cronic computer trouble. Have replacement to Rick. Waiting installation. Need to install small antenna in 433 MHz range to link Mechanicsburg to Mutual

• Mutual - Offline, wiring issue, waiting to hear from Rick.

• Richwood - Online

• Springfield - Online

• West Liberty - On hold

• Worthington/CMHSW2 - Online, recently added 3.585 USB WINMOR port. Ideally want to install end fed half wave for 30m and 80m to help reduce crosstalk.

• Worthington/CMHSW3 - Offline, hopefully pending move

• Upper Sandusky - On hold, Richwood side is now online. Get in contact with station engineer. See what facilities are available. Reach out to local club to see if any sponsorship can be gained (Mainly antennas, feedline and power supplies). Ideally would like to link to Richwood, possibly Mechanicsburg to the south then Findlay and Tiffin to the north.
