Hi folks.
This may in the wrong thread apologies.
Any difference between the grey and blue radios?
Both are model 100D, this is confirmed by the front
Panel.
Would be very grateful for a quick response
Many thanks

Blue would be later manufacture, not sure what the technical differences would be.

Yes, wrong forum. It has nothing to do with where you posted it (PowerSDR).
The grey faced units are older and probably have an older revision RF/PA card in it. The older Rev. 15/16 boards used EXT1 as the feedback path for PureSignal. To better understand the differences see the
schematics.
You might also have an internal linear power supply instead of a switching power supply.
