Hi Clinton,
now I understand a little bit more.
Please change your setup to 20s or maybe a little bit more.
10h is useless and you will have airbournes which are not real flighing.
The other point open speaking I do not understand
It seems that you are matching mV and mW
The adjustment is for the internal AMP inside of the stick. It is a Reference Voltage not Power itīs for the internal comparator. Inside of the ADSBstick you can adjust this reference voltage with ADSB Scope. The GNS 5890 is doing it by themselves dynamically.
Please for the antenna ..height and direct view is everything.
If there is something between Antenna and airbourne you can not receive well.
Because of the Power of the ADS-B signal from Airplane....
The fieldstrength is different therefore there is a need to have a internal amplifier. You can imagine that this is not easy because you have very noisy signals and very small signals you want to detect.
This is for example the reason for the donought effect which some receiver have.
regards
Bernd
