Brian, I will defer to Kevin, Steve, Mike, and others who have far more experience in performing this conversion than I have.

OK I think there's an inductor and/or a resistor that's need to be changed ...... but that would leave the IF strip intact? Right? Brian, WD9HSY ********************************************* Chris, You bring up an interesting point. I simplified my previous response because the poster had a DVP station he wanted to use for conventional operation. In this scenario, it really wouldn't matter which exciter or receiver board was installed. The reverse scenario, that of operating a conventional station in a digital mode, is something I did not address. I certainly agree that the exciter and receiver from a DVP station are the best choice for digital modes. 73, Eric Lemmon WB6FLY ************************************************************* [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> writes: There's nothing different about a DVP station other than the backplane, SCM, and the DVP processing modules. All of the RF equipment is plain old Micor stuff. 73, Eric Lemmon WB6FLY Eric, If you have the DVP manual could you check the part numbers on the IF filters? I was always under the impression that they were spec'd for flatness and group delay to be able to pass 12KB securenet data without distortion. I have been looking for a DVP Micor to find out if I could use one to build a Digital transparent repeater that would pass D-Star, IMBE, and AEGIS similar to the ones built out of Maxtracs.
