Example Radio Memory Programming

  • Besides Frequency and Offset, for D-Star there are

three additional key fields: UR, RPT1 and RPT2

  • Example:

Potential Local D-Star Repeater Project

  • ICOM currently has special pricing to the end of

the year

  • Cost is approximately $1600-1800 for

VHF and control modules. Would not include duplexers or computer, but we can probably use existing assets for that.

  • Tax-deductible donation opportunity for anyone
  • interested. Looking for donors that would be

willing to donate a minimum of $100 each.

  • We currently have about $700-800 pledged from

both Longview and Tyler club members. So, we are almost half way there!!

  • Will need to purchase before year-end
