Hello Glen and Matt, I've been going back and forth with David here about a very low cost SDR for 2M/70cm and a few concerns have come up. The main one has been dealing with strong interferers at a very near by frequency. Do you guys have any suggestions to to help mitigate receiver overload/desensitization? I've attached a block diagram of the radio we're working on. Here's a link for the datasheet of the RX IC we're using: http://www.cmlmicro.com/DesignSupport/resources/2012/11/23/CMX994-Datasheet What sort of specs should we aim for to have good strong signal performance? Any suggestions will be greatly appreciated!
