Here is a list of things we are collectively working on.


  • Acquire/split up power supplies at CMHSW2, CMHSW3, CMHSW4, #RCHWD to handle higher load from Midland LMR Radios
  • Acquire large spool of RG-213
  • Continue to acquire gear/test equipment for shared workshop. Will need antennas to cover as much HF as possible, 6m, 2m, 222 MHz, 70cm. Spare power supplies, few computers for workstations/web search, eprom burning facilities, packet host to test cables for 4 main interfaces: soundmodem(Linux), DRSI, TNC2, Kantronics 9 pin.
  • Locate Midland LMR radio which will cover 430 MHz, several are candidates including:
  • Locate portable computer, 20amp switching power supply and appropriate cabling for a portable LMR programming station covering both Syntech I and XTR/Syntech II models.


  • Build cabinet for #RCHWD site, must house computer, radios, power supplies, TNCs. Computer should have 2 serial ports and wireless network card.
  • Build Tennis ball Launchers to aid in installation of antennas in trees
  • Construct small 222 MHz antenna to be installed very high at CMHSW3 site in hopes of having a clear shot to CMHSW4.
  • Implement 10m FM 1200 Baud RF ports on CMHSW2, CMHSW3. Folded dipole constructed for CMHSW2, need coax. Tentative frequency of 29.685 MHz.
  • Establish 70cm 1200 Baud link between CMHSW2 and CMHSW3 in 441 MHz range. CMHSW2 will use 70cm side (Duplexer is on site) of AR-270B. Unknown antenna for CMHSW3.
  • Install APRS Digipeater at N8FRT's QTH. Use directional antenna to favor 71S of Columbus.
  • Rebuild N8FRT's hamshack computer with Ubuntu and configure Soundmodem as needed.
  • Build colinear PVC J-Pole for KD8HEZ Home/Voice station


  • Work on Radio/TNC/Computer setup for CMHSW1 site (Lincoln tower)
  • Wire up BPQ Polling cable for CMHSW2 and #RCHWD. Connectors have been ordered.
  • Burn appropriate BPQKISS eproms with Channels A-F for CMHSW2, A-D for #RCHWD.
  • Investigate 30m APRS HF I-Gate, unsure of location, probably CMHSW2 or maybe CMHSW4 if compact antenna is devised.


  • Continue to modify Midland LMR Radios for Microphone Pre-Amp installation in radio
  • Replace 6m, 2m, 70cm radios at CMHSW2, CMHSW3 and #RCHWD
  • Upgrade 222 MHz link from CMHSW3 to CMHSW4 to 9600 Baud. Free up second KPC-9612 to begin testing. Probably QSY frequency down to 223.400.
  • Allocate recycled 2m Mobile radio for KD8HEZ to use, reacquire IC-27a from his mobile setup.
  • Fix man door to garage at CMHSW3, begin building benches and running electric
