[Hammarlund] HQ-110 mods.

[Kenneth G. Gordon]

I have heard that there were a very few mods for the HQ-100/110 series 
receivers. Some of those, at least, were designed to help with the audio 
quality. Others may have had something to do with stability.

I have searched the web pretty thoroughly for those but have not found 
any. 

Does anyone here know where those might be found, or would anyone 
here have those they could send to me?
