The world seems to be going to direct-conversion I-Q receivers with the
baseband going to a DSP for processing. Reverse for TX. I think this would work fine for any mode on 2m, including FM if you're clever with your algorithms. You are right, for example most of the 802.11 or Bluetooth solutions are zero-IF, but I don't think that this is ideal for Ham Radio (the main issue is re-injection of the LO into the RX). A better option (for us) is the low IF option (like in the DSP10). The DSP10 has an IF at 19.665 MHz and one at 15 KHz. The concept is excellent but slightly overdesigned for what I want to achieve. The drawback (when compared to zero-IF) is that the low-IF receivers still requires dual conversion and IF filters to achieve any level of performance. |
