One important thing that has not been mentioned on this receiver. It has no serial port, RS232 connection. There is also no force load procedure, via the usb, to date from Vantage to un brick this receiver if you happen to lock it in "boot " mode. I have sent Vantage numerous request and various samples of force load procedures from different manufactures but to date have gotten no response. This means a trip back to the manufactures or if lucky the supplier if he has been given the info.
I have been using the Vantage receivers for over a year and locked two to date. My foolishness by experimenting with file releases and channel editors to try to correct some of the bugs. The 1100 is a good receiver and with the stutter issue corrected has the potential to be a great little unit probably untouched dollar for dollar.
