Re: Attenuation for microphone check
Not sure what your exact intention is with a “mic check” (this could be one of several things) – however, one thing that comes to mind is to consider transmitting into a dummy load and then putting the TinySA antenna near the coax.
?
Steve, KW4H

I want to check the response of an Astatic D104 microphone through my Kenwood hybrid. I can only output ~100 watts with the hybrid and cannot dial down the power without a modification. I would like to run a mic check into the TinySA but
100 watts will blow it to bits. Has anyone tried this or calculated how much attenuation is needed?

Re: How do people keep getting clones?
#tinysa
It's not so much that people are cheap. The clones are not significantly less expensive than buying a genuine tinySA from the Zeenko store on Alibaba or Ali Express, or from R&L in the US. They are a bit cheaper than buying from Eleshop (Europe) or Mirfield (UK). It's more that they are impatient; it can take weeks to receive one through the Zeenko?store unless you're willing to pay a high shipping fee, and the authorized resellers are often out of stock. The official store is also sometimes out of stock.
So people try to buy them from eBay or Amazon sellers because they can get them faster. And occasionally somebody sells authentic tinySA there. But you're far more likely to get a clone.

PRESS RELEASE For immediate release Release date: 03/12/2021 FAKE NEWS HUMOR
A research team led by Quincy Raymond Michales, and Quincy Thomas Holmes, of Miskatonic Medical University have discovered two new genes potentially involved in Amateur Radio Cheapness disease, or ACD. They identified them by exploring which genes were turned on and off in the hippocampus of people who suffered from the disease. The team's findings are published in the February issue of QST magazine.
Amateur Cheapness disease, (ACD), is a neurodegenerative disease that involves extreme pain and the formation of protein plaques around neurons in the brain when any amount of money is spent, no matter how small. A table below outlines the effects of spending on a typical Radio Amateur:
Amount Spent Pain level ================================================================================= $00.00 - $03.00 Little to none $03.01 - $05.00 Some pain noted, with slight thoughts of building a replacement for less. $05.01 - $10.00 Marked increase in pain, actual designs thought about for replacement items. $10.01 - $20.00 Sustained pain, over longer time frames, designs being drawn up. $20.01 - and above Extreme pain, and actual urges to construct replacement devices. Table 1
A secondary effect was also noted, once the Amateur decides to build a replacement item, (see $20.00 and above in Table 1), to save money, the process begins to feed upon itself, as the Amateur shops for parts for the replacement item, he/she, experiences the effects of Amateur Cheapness disease overlayed on top of the original Amateur Cheapness Disease infection. In some cases this becomes completely debilitating to the Amateur involved. This process is extremely painful. In some cases, observers have noted this fact by observing statements such as:
1. "Oh my God, its like the walking dead in this hamfest, no one is spending any money". 2. "You have got to be kidding me, I paid good money for that thing, and I'm not giving it away". Table 2
The hippocampus, part of the brain involved in memory, is one of the first regions to sustain massive damage, followed by the reasoning center of the brain.
Many genes were already known to contribute to the disease, such as gene JT-65, and gene FT-8, but two were unknown, FST4, and FST4W. The FST4, and FST4W gene action is as of yet unknown, the researchers simply noted these genes expressed at the time of hippocampus destruction.
In a related study, it was noted that the size of the hippocampus was actually reduced by up to 12% in Amateur Operators experiencing this disease. Further this second study indicates that ACD, (Amateur Cheapness disease), is far more prevalent in the Amateur Radio population than initially thought, and that signs of airborne transmission are becoming apparent.
Overall, the new findings improve our understanding of the genetic and cellular mechanisms that cause ACD. Also noted by the researchers were some tell tail signs of this disease. Effected Amateur may make statements such as:
1. I bet I can build that for half the price. 2. That's outrageous, when I was a Novice it only cost X dollars. 3. There's only like twenty bucks in parts here, I could build it for half that. 4. I only buy used if it is 25% of new price. Table 3
The authors add, there are a number of other symptoms involved in this sadly debilitating disease, however they are far too many to cover in a single paper. Thus, more funding is requested for the effort.

It does look like we made it, but the attenuator is broken, we suggest you contact your supplier for a new tinySA. we will provide the supplier with a new tinySA host.

Table 1
A secondary effect was also noted, once the Amateur decides to build a replacement item, (see $20.00 and above in Table 1), to save money, the process begins to feed upon itself, as the Amateur shops for parts for the replacement item, he/she, experiences the effects of Amateur Cheapness disease overlayed on top of the original Amateur Cheapness Disease infection. In some cases this becomes completely debilitating to the Amateur involved. This process is extremely painful. In some cases, observers have noted this fact by observing statements such as:
1. "Oh my God, its like the walking dead in this hamfest, no one is spending any money". 2. "You have got to be kidding me, I paid good money for that thing, and I'm not giving it away". Table 2
The hippocampus, part of the brain involved in memory, is one of the first regions to sustain massive damage, followed by the reasoning center of the brain.
Many genes were already known to contribute to the disease, such as gene JT-65, and gene FT-8, but two were unknown, FST4, and FST4W. The FST4, and FST4W gene action is as of yet unknown, the researchers simply noted these genes expressed at the time of hippocampus destruction.

My TinySA doesn't do the attenuator test. All other tests pass OK. Older versions work fine.

Try updating the firmware and running the self-test.? Clones will fail.

Hi – I just received a TinySA from a vendor listed as legit.? On the back of the unit, for the serial number, is just says “SA-“ and then nothing after that.? Just checking to make sure that this isn’t a clone.

We have a TV/comms tower on the nearby hill with some nice bright red flashy lights scattered up it, helps stop the hairplanes bumping into it. They've also been known to sometimes attach powerful lasers to it as well purely to make pretty colourful night light lines going far across the sky (tends to upset the local home based astronomers though).

Thanks! That is what I was looking for!

Not sure if this helps but, according to an app installed on my phone, anything above -90dBm is regarded as good, above -97dBm as marginal, above -102dBm as poor with -110dBm as the cut of as unreadable. I think that's what the OP was asking... John G0GCD

It's an epidemic in the ham community and has been for decades.? An antenna, and the line that connects it, is the heart of a ham station.? I'd much rather run an old hand-me-down rig with a properly installed antenna than a multi-thousand dollar rig and a garbage antenna or feedline.? And the antenna doesn't have to be BIG -- it just needs to be installed RIGHT.
