This doesn't directly have anything to do with discrete codes but I decided to measure my RCA DirecTV receiver's current flow between On and Off. I have often heard speculation about how much power it consumes. I thought it would be useful to quantify the economic value of a discrete power command.
Both On and Off fluctuated between 100 and 103 mA RMS on a digital multimeter. That means these devices consume approximately 12 watts (117 V*.103) on or off. Since many of the DSS receiver functions go on in the background, this is not an unreasonable result.
So for me (12 watts*24 hours*365 days*.0377)/1000=$3.96 per year (24x7x365) my electricity rate being $.0377/KWHr. This of course is On or Off.
So I think the little LED for power on a DSS receiver is a giant practical joke by the DSS receiver manufacturers ;)
Anyone else get materially different results? Remember I am only talking economics.
