[QUOTE="Terryl, post: 1134395, member: 369937"] I don't have the modified receiver anymore, but I do remember a bit on what I did. After a bit of poking around I found the variable voltage chip and circuit used to switch between the two voltages, I cut the trace for the main output voltage and did use a .1 ohm resistor like you mentioned in series, this allowed me to monitor the DC voltage going into the resistor, (voltage going to the LNB and the voltage drop across it, (current measurement) the circuit involved had RF suppression components to keep the circuit from interfering with the RF signal from the LNB. It worked fine till one day the main tuner took a nose dive. [/QUOTE]
