John,
On the TMCC Signal Booster (SMC) schematic in the PDF there is a AD774SQ op-amp part. The AD suggests its an Analog Devices part, but I did not see any 774SQ parts. Is this the correct part number? Do you have a link to the datasheet for this part? You might want to include a complete parts list with the instructions. Is the 24VDC wall wart power supply regulated? What is the amperage rating on the wall wart?
