|AVRT5 APRS tracker|
All measurements were made with a 6dB attenuator and 1m RG58CU between the Tracker and the Analyzer.
HF Signal - 144.800MHz
|Power Measuring: 30.46dBm / 1.1Watt|
|At -5khz from center freq we measured a delta of 41.18dB|
|Harmonic frequ: The 1st harmonic at 289.7MHz has a delta of -9.13dB. That is too high for using it for a permanent digi. A filter is needed to further lower the harmonic signal.|
