Quite often it turns out that you want something just because you want it, not for any good reason or practical purpose but just because you want it. For some unknown reason I have now decided that I want a FR-114U Digital Frequency Meter.
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.
But there it is, insanity has no limits. I want a first generation huge digital frequency counter.
Nothing happens in a vacuum, this weird desire to want a FR-114U stems from seeing one on EBay at:

Just don't want to pay that much money plus shipping!
