[Milsurplus] Info wanted: AN/GRC-87 and another

[Kenneth G. Gordon]

I think the AN/GRC-87 is a variant of the AN/GRC-9, but hopefully, 
someone can fill me in on the details.

Also, there was a solid-state version of the AN/GRC-9 that MAY have 
been called the RT-524, although I thought that was a VHF rig.

Anyone know what I am thinking of? At one time, I had the receiver 
portion of some sort of really neat small solid-state HF rig, but mine had 
no nomenclature plates on it, so I never did find out what it was, 
exactly.

Does anyone know about something like this?
