[Heathkit] HR-10 Improvement on 10/15 ?

[Ross Stenberg]

I think that it is easier, cheaper, and better to just buy a softrock 
receiver. Blasphemy I know, but trust me. One of the better receivers 
that I have used (which has been many) cost me $18 several years ago. 
Nostalgia is one thing...performance is another. Computers are rather 
prevalent these days.
