I am using Windows 7 Home Edition and my amplifier is the 8410. Under Calulated Data I am showing the following on 20 meter band as an example:
Plate disipation 0 W
Grid 1 Disipation 0.0
Wasred heat 1 W
Can these readings possibly be right?
The calculated data in the monitor is updated as telemetry provides new data from which the calculations are made.
Gain Gain is reported via telemetry regardless of whether you're transmitting or not (or even powered up) thus the dB calculation is always present.
Plate dissipation Plate dissipation is calculated from efficiency, plate voltage and plate current. Efficiency, like gain, is always reported via telemetry regardless of whether you're transmitting or not. Normally the plate current returns to zero when not transmitting but when the amp is off, telemetry may report an insignificant plate voltage (mine shows 3 V) and a very large plate current so plate dissipation may be positive with the amp off.
Grid dissipation Grid dissipation is calculated from grid voltage and grid current. Grid voltage is always reported via telemetry and grid current normally returns to zero when not transmitting so the grid dissipation does too.
Waste heat Waste heat is calculated from peak power output and efficiency. Since efficiency is always positive and always reported, waste heat will only go to zero if peak power does. Peak power is averaged in firmware that results in positive peak power values being reported via telemetry a significant fraction of a second beyond key-up. This will result in waste heat being positive shortly after key-up as well.
When the amp is powered off telemetry reports some nonsensical values like 2+ amps of plate current. I thought about ignoring all of these when the amp is off (state = 0) but elected so far not to. The monitor was meant to show telemetry, good or bad, and not selectively hide some of it. Whether it shows up is better controlled in firmware.
I'm assuming you're observing these values when the amp is idle or off. If you're seeing these values when transmitting then there's a problem.
If you can reply and attach a screen shot or two of the monitor I can provide a more definitive answer as the raw telemetry string and all the parsed and calculated data are captured.
