Adam VA7OJ has/had various files about the 7610 architecture on his web site. The 7300 has a 36kHz post-FPGA IF which is demodulated by a DSP chip I believe, the 7610 does all of this inside the same FPGA to which the ADC samples are sent. They're very different in overall architecture which is why they behave very differently with the AGC off. -- Brian G8SEZ _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
