What are the typical ADC and VSWR values (for fault finding) for the A100?

The following figures relate to typical values seen in the diagnostics screen of an em-trak A100 Class A unit working in high-power (ie 12.5W). These figures reflect what you ought to see when a unit is connected to a suitable VHF antenna, GPS Antenna and PC Comm Port.

Diagnostic Values on the Unit:

Internal GPS Status:

GPS Locked

ADC & VSWR:

Ch0 – Needs to be over 100 (typically around 140-150)

Ch1 – Needs to be under 50 (typically around 20)

Ch2 RSSI Rx1 – About 50 (can typically vary between low 40s to mid 60s)

Ch3 RSSI Rx2 – About 50                  “                        “

Ch4 RSSI Rx3 – About 50                  “                        “

Ch5 ADC Channel 5 – Below 70

Ch6 6v8 Supply – About 06.8

Ch7 13v8 Supply – About 13.8

VSWR Last Transmission: (Good VSWR is less than 3:1)

TX power level: High (if in high power mode)

Forward Power – Typically around 220

Reverse Power – Typically around 15
