[Elecraft] RSP-1A as panadapter

[JR]

I use a couple of RF limiting protection devices, each purchased on 
eBay.com, with my RSP1a.   One is Chinese and cost $20,  and the other 
is from Slovenia and cost $32 (I think).   I have had excellent helpful 
communication with the maker in Slovenia.   From what I can tell, they 
are each constructed with similar parts/circuits, and limits RF which 
could damage the receiver.   A local electronics guru / Elmer who used 
to design radio equipment for NASA and the Air Force reviewed them and 
considers them appropriate to the task.   I use one of these RF limiters 
whether I connect the RSP1a receiver directly to the rig or to a 
separate antenna outside.

Other ops use similar RF limiting devices from Array Solutions and 
DX-Engineering, which I am confident are also appropriate to the task at 
around double the cost of mine.  Just another way to skin the same cat.

Just my take.    K8JHR
