The SX-1HD-1ST 1-Channel Bi-Directional Video Transmitter from Meridian Technologies features a built-in re-clocker and transmits multi-rate SDI / HDSDI videos. This serial digital video transceiver provides broadcast-quality transmission of the industry-standard range of digital video data rates. It supports one, bi-directional channel of SDI / HDSDI video over one fiber in each direction. This rack-mountable card transmits and receives real-time video. The built-in re-clocker supports 3R (Retiming, Reshaping, Regenerate) functions and dual buffered outputs. One buffered output can be set as a time base (clock).
This transmitter supports buffered loop-through, which ensures maximum performance over long distances. No video compression is utilized. It supports 1-channel of SMPTE bidirectional 292M, 310M, 259M, and 344M compliant digital video data rates over one multi-mode or single-mode fiber for each channel. No user adjustments are needed, thus ensuring fast deployment and setup with broadcast quality results. It can transmit and receive on both multi-mode and single-mode fibers. This enables you to convert the type of fiber in mid span.

Amazing Energy Boost
This gave me an energy boost immediately after I first took it. It worked so well, so fast, I thought it could not be from this product. Nothing works that fast right? But this did for me.
This is my first time taking Spirulina. I’ve taken supplements and used energy drinks but none had noticeable effects. This Sporulina does.
It is easy to take in this pill form. I curled my fingers in the photo to show how much green residue gets on you when you reach in the bag. It’s a bit more when the bag is brand new. I am halfway through the first, around two months. The green washes off easily with water and does not stain.
It does smell like fish. The odor is stronger when the bag is new. It barely has any taste so breathing through your mouth makes it easier to take if you don’t like fish. I like fish, but not strong fishy fish like mackerel. This is medium fishy when new and is still easy for me to take.
The energy boost was incredible for me. You might not have the same experience. I am a bit older than middle age male. That likely played into my increased sluggishness.
I sleep better after starting to take this. I no longer need to sleep in, and I am not foggy headed all morning. I’ve never been a morning person but now find I can hop out of bed and be ready to go early in the morning. Incredible for me.
I now fall asleep easier and stay asleep. When I do get up for the bathroom I can fall right back to sleep. Ive had sleep apnea my entire post HS life and possibly before. This did/will not cure that and I still use a CPAP. I was alway very trim and fit. So I wonder if this would have helped my sluggishness in my younger years. If that is you I would definitely give this a shot.
I have no idea what is in this that I needed but it is nothing short of amazing for me. Quality multi-vitamins or greens never did this for me.
Hard to beat all that and that a four month is just over $20. Hopefully the price stays there.

Pure energy and nutrition in a scoop
I’ve been taking organic spirulina for a few weeks now, and I can honestly say it’s made a noticeable difference in my overall energy and wellness. The quality of this product is outstanding—deep green color, fine texture, and no weird aftertaste, which tells me it’s truly clean and nutrient-rich.
I love that it’s USDA organic, non-GMO, and free from fillers or additives, so I feel confident about what I’m putting into my body. I’ve been adding it to my morning smoothies and even mixing a bit into water or juice—it blends well and gives me an instant boost.
Since starting spirulina, I’ve felt more energized throughout the day, and it’s helped curb my cravings between meals. My skin also seems clearer and more vibrant. It’s packed with plant protein, iron, and essential vitamins, so it’s now a staple in my daily routine.

More Hilarious Aristophanes!!!
Format: Hardcover
Here we have a fantastic translator of Aristophanes, Jeffrey Henderson who has translated all 11 of Aristophanes' plays, who in this handy volume presents us with all the remaining fragments of the great comic playwright.
Translated and published in 2007, this is a welcome edition to go along with whatever you already know about Aristophanes!
I believe that without these fragments of his unknown plays, our picture of Aristophanes is incomplete and somewhat biased. And this goes for Aeschylus, Sophocles and Euripides as well. People who love the ancient playwrights need to know about what else they did besides what is already out there. That's why I love these Loeb Fragments editions! They reveal so much more about the dramatists' genius, art and ouvre.
Here's the breakdown of this ultra-rara Aristophanes volume:
1) TESTIMONIA (of Aristophanes):
Life, Father, Mother, Sons, Homeland, Era, Works and Competitions, Actors and Producers, Feud with Cleon, Socrates, Eupolis and Plagiarism, Baldness, Portraiture, Critical Judgements, Metrical Art, Editions and Commentaries, Epigrams.
2) ATTRIBUTED FRAGMENTS (of 36 Plays)
3) UNATTRIBUTED FRAGMENTS
4) DUBIOUSLY ATTRIBUTED FRAGMENTS
5) INDEX
This is a fantastic accompaniment to those seeking more comic relief outside Aristophanes' already known plays!
