HPSDR PA Gain for Hermes
After adjusting for 10W output with PowerSDR drive set to 100 from the Hermes ANT1 port, as measured with an HP 8482H power sensor and 30dB power attenuator, the PA Gain table looks like this:
In operation, drive is set to 75 for each band, which yields 70-80 watts out of the TenTec 418 amplifier when that amp is set to 0dB attenuation. At the moment, the TenTec amplifier seems unhappy when measuring its 6M power using the 6M ANT output.
