[GreenKeys] UPI on the air (Was: ITTY channels offline)

[John Hargett]

Paul, 

Thanks for keeping this going.  I have been able to catch a glimpse of the man ( and the equipment) behind the curtain when I came up and picked up the machines that came back to Texas.  I have a great deal of respect for the work you put into this and intrigued by the workings from your basement.  I have since picked up 2 more 28KSR  and I am looking for a mite to run with my PRC-47.  I really appreciate you running this and keeping it going and the time and effort it takes is beyond us.  My granddaughters are intrigued by the machines, and can’t wait to get them hooked together to use from the shack to the house.   
Like the others, just keep the A-Z and 0-9 coming across and if we don’t like what we see, we’ll quite often I just turn off the TV or go outside and play with the dogs, but to keep a feed running to keep these machine operating and able to show what they can do is greatly appreciated. 

Thanks again
73
John
