Re: [time-nuts] Wanted - AN/URQ-10 manual
Goodness FORTH and a R1051. Who would have thought. I am a big fan of forth also. Loved the way you could extend the dictionary. Plus it ran like a bat out of heck fast. Like you I went through ETA school as the second class to be trained on the 1051. At $27,000 each did not think I would ever own one. I do have a operational 1051 purchased many years after leaving the service from Fair Radio and a RT-918 all operational. Though the RT918 was a serious $25 basket case from the air force. DDS for the 1051. I have often thought about that. Today they are so cheap that you could build a composite unit or 3 or so separate ones for the translatersyn. What will drive me to do that is the pesky aging crystals that I have already had to deal with on the RT918. To keep this in a time-nuts spirit, they all run on the RB reference or the GPS reference. See back to time-nuts. Regards Paul WB8TSL On Sun, Nov 18, 2012 at 3:32 AM, DaveH i...@blackmountainforge.com wrote: Another FORTH fan here.
