12 PA and LPF modules.ġ2 PA uses a single ST Micro STAC2942B (a twin MOSFET device rated for Po = 350W) in its output stage. Still, if the IC-7700 is new and has a serial number as described above, it will have the Rev.

The PA board is on the underside of the heatsink, so the assembly must be released from the chassis to view the board.

The PA board is difficult to inspect as it is mounted on the finned heatsink with the fins towards the top. Other prefixes are 11 for Japan (domestic) and 13 for EU. Hi Alex, If the first digit of the country/region prefix in the serial number is 1, the IC-7700 is unequivocally a Rev.ġ2 is the US/Canada version with S/N of the form 12XXXXX. The RS-232 serial port is the COM port on the computer. Hi, I wonder if anyone knows how to decipher the serial numbers on these receivers to get an approximate year of manufacture. 12 only apply to USA models or to 7700s worldwide? Is there any particular serial number I should look for that may help in the identification of whether the unit is pre- or post- revision? Free Download Remote Desktop Software Crack Sites. Does anyone know how to tell what number the PA board would have on any particular unit? Further, does Rev. 12 PA board that seems to have solved the issue. I've read about newer units with the Rev. There is no Icom dealer here in Hong Kong and so if this unit does join the Blown Finals Club I'd have to go through the dealer to have the unit shipped back to Japan and endure all the associated hassle that would entail. I'm tempted to pull the trigger on a brand new IC-7700 that's sitting in my local dealer's shelf (as he's offering a good price for it).
