Memory does seem to go sometimes! I do remember where my shop is but 
have trouble finding things on the computer at times.

Have been looking over all the ACP's that I downloaded. Didn't like 
reading them back then but enjoy doing so now.

I worked in comm centers all the time. Voice, TTY via satt and HF and CW.
For awhile I ran CW training for the ships in company with the us (USS 
Ranger). Long ago forgot what the name of the CW keyer was. You would 
type on it and it would send out CW. You could adjust the speed and it 
would put the text into a buffer if you could not type fast enough to 
keep up. I would type in the AP or whatever news we were copying at the 
time. Really liked that little box.
