Is there a "first step" that could be made to permit MAP65 to be used with Winrad and an SDRIQ receiver, if only one polarity was involved? Many of us do not have crossed polarity systems, and it would be a great advance if we were able to use the Winrad/SDRIQ/MAP65 system with our very primitive antennas! Good luck on this exciting project, and I look forward to hearing more about your progress! MNI TNX and VY 73, Lance -- Lance Collister, W7GJ (ex: WN3GPL, WA3GPL, WA1JXN, WA1JXN/C6A, ZF2OC/ZF8) P.O.
