Bob,

The one-button QSY is great for bands supported on the subject radios. Thanks for highlighting it. I wish that was better promoted. In my case, we have 23 centimeter and HF to contend with, hence the low-tech procedure. Note to the radio manufacturers. Give us more bands on APRS radios, or add APRS to radios that already have them!

73,

When we try to get volunteers for events, we don't have much control over the kinds of equipment they bring. I was trying to support using very basic APRS systems during times when the telecommunications grid is unavailable.
