The Epson Toyocom has landed too.

epson10mhzFirst Impressions

It was only a 10 day trip from China for this 10MHz frequency standard to arrive at my station. It looks like the pictures on EBay and has four standoffs on the circuit board for mounting into an enclosure. The BNC connectors also have the necessary hardware for mounting through a sidewall. The circuit board layout is substantially different in the details than shown on Ebay. They layout seems to be flipped. That means there are more than one layout or version, but this is not a concern of mine. Just an observation.

All in all a very impressive looking piece of electronic hardware. This is a first look impression. The real proof is of course in performance. 

It will be awhile before I can rig up a test. Perhaps one of the clan members at NTMS can help with frequency and calibration tests. ha! From what I have seen, there are folks that love doing that.

There are no data sheets or other instructions provided with the delivery. Here is a datasheet I discovered just for the TCO-6920A Xtal dual oven. TCO-6920A.pdf

I assume from the EBay photos there is a built in splitter for the two outputs. I also assume a termination load may be required if using just one output. I see what appears to be voltage regulators on the PC board but I further assume something more stable than a wall wart will be needed for the power supply ( 12 or 15 volt). Hmm... that's a lot of assumptions! :)
