Example Radio Memory Programming • Besides Frequency and Offset, for D-Star there are three additional key fields: UR, RPT1 and RPT2 • Example: UR RPT1 RPT2 Comments CQCQCQ^^ N5VGQ^^C N5VGQ^^G Used to Communicate ^^^^^^^U N5VGQ^^C N5VGQ^^G Unlink ^^^^^^^I N5VGQ^^C N5VGQ^^G Information REF004BL N5VGQ^^C N5VGQ^^G Link to 004B Refl REF048BL N5VGQ^^C N5VGQ^^G Link to 048B Refl REF001CL N5VGQ^^C N5VGQ^^G Link to 001C Refl ^^^^^^^E N5VGQ^^C N5VGQ^^G Echo Test Saturday, August 31, 13

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 Saturday, August 31, 13
