[Boatanchors] HRO-500 Data Sought

Fri Feb 13 21:46:49 EST 2009

Hi Carl,

Would you be willing to lend me the National documents that you have. I 
would be happy to scan them and put on BAMA or any other place that you 
want. I of course would send you PDF of all the files for your records.

I have a scanned manual of the HRO-500 ver 122 manual which is the HRO-500 
that I have. I also have the I believe 1965 Popular Electronics magazine 
that showed the HRO-500 on the front cover.  When I saw that receiver on 
that cover (in 1965) as a 15 years old I knew I needed to have one of those. 
Well it took awhile and I believe I was oh oh oh 53 when I got the HRO-500.

If you want to see some of my scanning work please check out the Collins 
Collectors Association manual archives. Pretty much 99% of what is in there 
came from my scanner. However the manuals came from hundreds of folks that 
entrusted them to the CCA and myself.

Recently I just scanned a 51J-2 and 51J-3 manual that I was loaned to me 
from Tapio KF7TY.

Thanks!

Larry WA9VRH
