[TenTec] In praise of older technology

[K3GHH]

Rick, I used an HRO-5 as a Novice. Each plug-in coil had a graph on the 
front showing a more-or-less linear relationship between the dial 
readout and frequency. I wonder how close to any particular frequency 
anyone could have gotten with that system?

Of course I loved it anyway... and never should have sold it...
