4.Support multi-band support, continuously adjustable 10m within 80m frequency range (from 20khz..99mhz, loss performance)
5.Open source firmware, built with arduino ide; allows experimentation, new features can be added, contributions can be shared via github, software complexity: 2000 lines of software-based Vovox code available for fast full control (qsk and half-qsk operations) or rx/ Auxiliary switch tx for external control of ptt/pa output using fully digital tx-delay stage and software based ssb stage transmitter in digital mode (no cat or ptt interface required): controls the phase of the sill si5351 (by switching at 800kbits/s Small frequency changes under i2c) and magnitude of pa (via pwm pa key shaping circuit).
6.Software-based all-digital SDR receiver stage (optional): The I/Q (complex) signal is sampled from a quadrature sampling detector digital mixer and a 90 degree phase shift is performed mathematically in software ( Hilbert transform) and three independently switchable analog faders (0db,-13db,-20db,-33db,-53db,-60db,-73db) from the pre-receiver by adding Atten sidebands.
7.Receiver noise floor mds: -135dbm at 28mhz (200hz bw).
8.Receiver receiver front-end selectivity: +/-2khz steep 45db/decade tuning frequency rolling.
9.Blocking blocking dynamic range: 20khz offset 123db, 2khz offset 78db.
10.cw decoder, direct/iambic-a/b keyer.
11.vvfo a/b + rit and split, and the corresponding relay through i2c.
12.cat supports cat with filter switch (using kenwood TS-480 protocol).

Runs like a Rolex
Color: 5535-ZP-blue
What a watch!! A very nice watch. Everyone asks if it is a Rolex!! I say NO but it keeps me on time like a Timex. The band is wearing a little quickly but otherwise thumbs up!

Most important review for this watch and company.
Color: 5566-ZP-blue face, Color: 5566-ZP-blue face
I bought two and they both broke. Customer service has ignored my e-mail. What more do you need to know about a company? I personally wrote them through their own website, so they could keep Amazon out of it. It makes me angry that they won't even reply to my e-mail. I was nice. Both watches broke, neither one if actually water proof. The band is exceptionally thin and it WILL break on you once it arrives. It's so poor, that my body moisture is what got into the face of the watch. What the heck? I've had better 9 dollar watches from Walmart. Zero out of zero for the COMPANY who doesn't care about their customers, and zero out of ten for watch quality. Useless. I wasted 60-80 bucks on two of these! BOTH BROKE! and in more than one way!!!!! Terribly marked up (this is less than a 10 dollar Walmart watch - quality is LOWER than the lowest 3 dollar watches off Temu, Shien, Walmart), customer service is non-existent, and the band WILL BREAK on you. It's worthless. Take your money somewhere else. Attached pictures show the moisture leak from my sweat, but in real life, it's actually much worse. Worthless, not usable. Two of them folks. TWO!

As Advertised
Color: 5535-HP-white
The watch is what I expected, and works upon receipt as advertised. At this price, if it only works for 4-6 months it's easily worth the money. Large, nice looking face, day/date. Wristband is what you'd expect, but adequate and comfortable.

Dies after a Year
Color: 5566-ZP-white face
Watch worked fine for about a year, then just stopped working - just like that. No amount of shaking or gentle impacts would get it to start ticking again. I'd also say my biggist issue with it was it was always difficult to tell which hand was the second hand and which hand was the minute hand since they're both the same color and thickness. Wish the hour and minute hands were a little thicker so they'd stand out a little better and/or that the minute hand was a different color so it was offset. Resulted in having to study the watch to get the time instead of a quick glimpse to see what time it was. Irritating after a while.
