[GreenKeys] LOOKING FOR THE JOHN SHEETZ RTTY ART TAPES

[David Christ]

Mine is undated but your date seems right as I have 50 more listed in mine.  Number 438-235 ran 235 minutes.  Clever how he included the time with the tape number so you could pick out the length you wanted. The numbers seem consistent between the two as 364-399 is blue boy in mine as well.

Someone can correct my math as I don't have any tape here at the house, but assuming 6 CPS in speed and a hole to hole spacing or 0.1 inch (questionable) you get 0.6 inches per second and 3 feet per minute.   A 399 minute tape would be almost 1200 feet long.  Someone please clean up these calculations.

Which brings up the question - how many feet of tape  on a normal roll?

While most RTTY Art tapes that Al sold were for 25, 50 or 75 cents, there were a few larger tapes. Tape 364-399 labeled The Blue Boy by Gainsborough was $12 and ran for 399 minutes.  That would be a great tape to run on a Saturday RTTY ART session...
