Hrothgar Update: Here is the latest. Here is the bottom line - with this machining layout I have accommodated every SDR ppl asked for and made this pretty universal. The heatsink profile is 7" long. The baseplate is the same 2.079" width as the heatsink profile, but an inch longer. 4 #4-40 SS machine screws sandwich your SDRs between them with a bit of heatsink grease you supply. If you have other SDRs (except Airspy and SDRPlays that I already know fit) please let me know your wish list. UPDATE: Hrothgar is in production. Latest pretty drawing attached.
