As mentioned in another thread, the Spectrum Analyzer needs these features:
1) Able to scan all frequencies and bands to find the transmitter a) If this is not easy due to technical constraints, workarounds will be needed such as scanning common frequencies, or scanning slower, or scanning every third frequency, and narrowing in when a signal is found. Perhaps all of these can be implemented, and perhaps others. This is critical, as the Spectrum Analyzer is not useful in its current state.
2) Once a frequency is found, the exact frequency needs to be displayed, and/or put in automatically into the TX/RX section.
I was looking at the specs comparisons, and noticed for the SDRplay RSP it shows 24Mhz to 1.8Ghz with 3Mhz bandwidth.. Looking at their specs it is actually 1Khz to 2Ghz contiuous and 8 to 10mhz bandwith. So the information you are showing is not correct there at all.
