The Elad is much better concerning handling strong signals.
I don't kwon the performance below 500 kHz but on MW it is very good. Only the Perseus is better.
Maximum bandwidth is 6144 kHz from which about 5 MHz is usable without aliasing.
You can use the Elad with its own FDM-SW2 software but also in SDR Console and many others with the Extio.
DRM can be done without extra licence in the FDM-SW2 software.
Your other question about DRM was answered in a separate mail.
