Re: Transmitter gain calibration
How are you measuring power output?toggle quoted messageShow quoted text
I have set up three K3s now and have found the following:
- my measurement of power was all over the place until I calibrated my power meters with against a professional one - HP438: my Bird was 20% out, slug cal was off with a very noisy cal pot. All my various power meters of various ages were out to some degree. Better agreement now.
- Out of the box the K3s are set to deliver higher power than indicated, around 10-15%.
- power can be set right at half power or full power (i.e. 5/50, or 10/100) but not both as the power measurement is not quite linear
- Low voltage limits power output, and dodgy power cables/ connectors can achieve this
Don’t know if this helps
