New acquisition:
Wilson WFC-500-E frequency counter
Something else for my new interest in radio. I snagged it for USD35 off of Craigslist. It came with the manual which includes a block diagram, description of operating principles, schematic, and parts list. I see ICs inside the unit with date codes from '76. It says "Made in Japan" on the back. The unit has a TOYOCOM-branded TCXO in it. This model is supposed to be good for 7-8 digits, but the last three digits (see picture from the manual) are either nonsense or my AWG is off from the frequency counter.
The BNC on the back of the unit outputs 1 MHz (even when the unit is switched "off"). The standby light turns on to show that the TCXO is still powered.
The power plug is not one that I have seen before. The seller said that there were different power cords available for Europe or Japan that used a different set of pins on the back of the unit that run to different taps on the power transformer. The power cord and power entry module show that there is an alternate universe where it's OK to plug any device you have into 100V, 120V or 240V and it will just work (if it supports that voltage) and no worries about blowing stuff up and little switches and jumpers to fuss with. I realize that's impractical for various reasons, but it could have been cool.
I also ordered a bunch of adapters from and to SMA, N connector, BNC, and UHF. Also a dummy load, a cheap SWR meter, and an attenuator. Next I've got to get me some nice coax with N connectors to wire everything together and test my knowledge of Watts, dB, Ohm's law, and equipment input maximum levels...

Wilson Electronics is still around, but they are now making cell boosters and 5G repeaters. I think they moved their HQ from Las Vegas, Nevada to somewhere in Utah.
