Dear Jim, Is this radio dual-conversion? I thought that, for proper DRM reception, the output had to be 12 kHz. Am I incorrect? What would you need to receive DRM with this receiver? Best, Joe Jim Hackett wrote: 455 khz I.F. output for DRM (Why they made it a PAL connector, I'll never know) The 455 kHz IF output is a plus, not just for DRM but for any software defined radio IF/demod. With software, you can demodulate AM/SSB/CW/FM and digital modes, have incredible variable bandwidth, shiftable IF filtering, noise reduction, improved AGC, spectrum display, etc. You need a 12 kHz or so IF to do the above via a conventional computer sound system and, consequently, a down converter between the 455kHz output and the computer. I guess that would make it a triple-conversion supehet receiver (if you don't count the A/D and D/A converters in the computer sound system!). Tom |
