7. The software vovovox code can be used for fast complete control (qsk and semi-qsk operations) or RX/auxiliary switch TX to be used in digital mode (no cat or PTT interface is required)
8. The PTT/PA output is externally controlled by the all-digital tx-delay stage and the software-based SSB stage transmitter: the phase of sill SI5351 is controlled (by a small frequency change i2c at 800 kbits/s) and the PA amplitude is controlled (by a pwm pa key shaping circuit)
9. Software-based all-digital SDR receiver level (optional): sampling of I/Q (complex) signals from a digital mixer with an orthogonal sampling detector, and mathematically perform a 90-degree phase shift (David Hilbert transform) in the software by adding an Atten sideband
10. Three independent switchable analog pushers (0db, -13 db, -20 db, -33 db, -53 db, -60 db, -73 db) from the front receiver
11. Receiver background noise mds: -135 DBM at 28 mhz (200 hz bw)
12. Receiver receiver front-end selectivity: +/-2 khz scrolling at steep 45 db/decade tuning frequency
13. Blocking dynamic range: 20khz offset 123db, 2khz offset 78db
14. CW decoder, direct/iambic-a/B keying
15. VVFO A/B + RIT and split, and the corresponding relays pass through i2c
16. The CAT supports cat with a filter switch (using the kenwood TS-480 protocol)

Package includes:
1. 1 x transceiver
2. 1 x the microphone
3. 1 x charger
4. 4 x machine floor Mats

Meh
Size: 10, Color: Black
I had a real leather version of these shoes for many years. They are still totally wearable, however the soles have worn smooth from using them so much. so naturally I buy a new pair. These are the same design. the stitching is close, the pattern in the leather is the same. But they are so much cheaper. There is no real leather. It's all synthetic. The sole is not the same quality of rubber. The stitching is not as good. They look fine, brand new, yet I am sure they will not last. these are cheap. They also cost less, so I guess they are an average value, but I am very annoyed.

The "Lazy Professional" Look: Is Hands-Free Luxury Actually Real?
Size: 9.5, Color: Black Napa Leather
Living down here in Florida, my footwear needs are pretty specific. It’s hot, it’s humid, and I spent half my life rushing from the car into work or a meeting. I’ve reached that age where I value efficiency just as much as style—maybe more. I’ve been eyeing the Marc Joseph New York Hands-Free Slip-on Penny Loafers for a while, and after putting them through the wringer, here is the honest truth from someone who just wants to look sharp without the hassle. The "Just Step-In" Reality Look, the big selling point here is the "Hands-Free" tech. We’ve all seen the commercials for those athletic slip-ins, but finding that in a legitimate leather penny loafer is a different game. Does it work? Yes, surprisingly well. The heel counter is firm enough that it doesn’t collapse when you slide your foot in, but it doesn’t feel like a piece of plastic digging into your Achilles once you’re in. For those of us who are tired of bending over or hunting for a shoehorn every morning, this is a genuine quality-of-life upgrade. The Florida Factor: Comfort and Style The leather is actual calfskin (on most models), which is a must for the Florida heat. Synthetic shoes turn into a sauna within ten minutes, but these breathe reasonably well. The aesthetic is classic—it’s a "professor" shoe through and through. You can wear them with chinos and a blazer for work or throw them on with some nice jeans for a weekend lunch. Inside, they’ve got a gel heel insert and a padded footbed. It’s not quite "walking on a cloud"—let’s not over-hype it—but it’s a massive step up from the hard, flat soles of traditional dress loafers. I’ve spent four hours on my feet lecturing, and my arches didn’t hate me by the end of the day. The Sizing Gamble Here’s where you need to be careful. The consensus from other guys (and my own experience) is that the sizing is a bit of a coin toss. They tend to run a little large and sometimes wide. If you have narrow feet, you might find the sides "gaping" or flaring out when you walk, which kills the sleek look. I’d recommend ordering a half-size down if you’re usually between sizes. The Breakdown The Pros: True Hands-Free: You can actually put these on while holding a coffee and a briefcase. No hands needed. Legit Materials: The calf leather feels premium and smells like the real deal. Versatility: Perfectly bridges the gap between a "car shoe" and a formal loafer. Comfort: The gel insert makes a noticeable difference for long-duration wear. The Cons: Sizing Inconsistency: They can run wide, leading to some "heel slip" if you don't get the perfect fit. Break-in Period: The heel is stiff by design (to allow for the slip-on feature), so expect a day or two of minor stiffness. Price Point: They aren't cheap, though often on sale. Value for Money Are they worth it? If you’re comparing them to high-end Italian brands that cost $500, these are an absolute steal. They look 90% as good for a fraction of the price. However, if you're used to $60 mall shoes, the jump to $150+ might feel steep until you realize you’re paying for the convenience of never having to touch your shoes to put them on. For a daily driver in a professional setting, the value is definitely there.

Step In Look Good
Size: 11.5, Color: Cognac Napa Leather
I am wearing these shoes as I write this review, and they look and feel great. I have a bit of a disability with drop foot on the right leg and bilateral neuropathy and have been wearing step in shoes for about 10 years. But the first company that introduced leather dress and casual shoes stopped making them and now only makes sport and casual shoes. So I have been searching for some that meet my need for shoes like this and this company has given me three pairs, so far. Easy to get into, comfortable to wear, and good looking. And they take polish very well, too. (Remember how to do that?). We may buy another pair or two in different styles as well.
