[Milsurplus] FR-114 Digital Frequency Counter

[Peter Gottlieb]

I have a General Radio frequency counter which uses the edge lit displays, pretty cool looking. 

Told you I have this disease.

The Hewlett-Packard 524 is big (AND-I am interested in one-the model with Nixies!), but with the plug-ins it can go up to the VHF region. They also "wrote the book" on early frequency counter accuracy. As for another device of that era, I'm trying to find a     military or lab rack mounted electric (as opposed to electronic) digital clock. Not a flip card or anything like that, but stepping relays activated by a motor driven switch to light indicators with lamps on the edges of engraved plastic plates. Like huge Nixies, the numbers dance in depth as they change. Some of these also had calendars as well.  I totally empathize with the attraction of older technologies, many of the instruments of that era exuded a vibe of confidence, optimism, and craftspersonship that has been supressed for too long and may never rebound.  Our computers and instruments today are truly awesome with what they can do, but the soul and often style of the classic gear is sadly missing. RAY- do you /did you ever have a PDP- "straight"8?  Now THAT would be way cool!

>>> For those unfamiliar with this device it’s a first generation vacuum tube digital frequency counter that counts up to about 1 MHz, it uses something called a Trochotron beam-switch counters controlled by a 100 KHz time base firing a 6D4 thyratron.
>>> Think I posted something in the past about the HP-524 family of counters but for now have given up on trying to locate a 524 thinking that the size and space requirements may be a bit too much for the current shop, keep in mind that this is being posted by someone who already has a couple full size PDP-11 systems along with a ton of other radios currently in the shop. Although I did sell off a broadcast transmitter that I had on 160 so that provided a hole.

>>> Nothing happens in a vacuum, this weird desire to want a FR-114U stems from seeing one on EBay at:
