Thanks for that Lamont.
The device is a transceiver and the power usage on:
Transmit is 850VA and on
Receive is 210VA
Wow John those figures are high -- is it a tube type radio?
210VA = 95.55W
850VA = 386.75W
Does sound like a tube rig.
Golly Brenda how does
210VA = 95.55W
850VA = 386.75W
wikipedia on volt-ampere
A volt-ampere in electrical terms, means the amount of apparent power in an
alternating current circuit equal to a current of one ampere at an emf of
one volt. It is equivalent to watts for non-reactive circuits.
Are you using peak, rms, or average factors?
I assume the VA figures given by John are rms values
thus RMS voltage is the amount of dc voltage that is required for producing
the same amount of power as the ac waveform
