Re: Cell phone signals
According to the Great Knowledge Base, the internet, -50dBm equates to 0.000000008 Watts, (1e-8). John VE7KKQ On Mon, Aug 23, 2021 at 8:06 AM Loren Moline WA7SKT <wa7skt@...> wrote: Correction: -50dbm.? |

Re: How do people keep getting clones?
#tinysa
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.

Re: TinySA battery no longer charging
Tried a different USB cable, made no difference. Tried a different USB charger, including a laptop USB port, no change.
What I tried was to completely drain the battery by leaving the TinySA turned on overnight. Then plugged in the USB cable to charge it. Charged for about 3 hours, but the battery voltage only gets to about 3.73v. |

Re: Firmware update
#tinysa
Here for me it was perfect. Wonder.
I just noticed that the automatic att of the HIGH channel doesn't seem to work, but it could be a problem with my square wave generator. But the problem I was having when calibrating, has been solved.
Thanks. |

¿ªÔÆÌåÓýErik ¨C it¡¯s a shame that the cloners have ripped off your product like this.?

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. On 8/23/21 6:17 AM, Erik Kaashoek wrote: Many people buy first from the cheapest seller and only later inform themselves about the tinysA73, Dave, |

To be sure to buy a genuine tinySA have a look at the "where to buy" list:?
Look at the serial number at the back of your tinySA.
If the number starts with "AD" its a clone. ------------------------------------------ For more info on the tinySA go to https://tinysa.org/wiki/ |

Re: How do people keep getting clones?

Erik hi I would just like to echo Larry's comments, the TinySA is a brilliant piece of kit ... ?... I bought my TinySA from a UK supplier that was listed as a recommended? UK dealer - and I paid in full straight away, i.e. I purchased in good faith.? As far as I can tell? my TinySA is genuine, the self tests run but I have not had to put it to any further tests, or upgrade firmware. Erik, I intended to buy a 2nd SA to use as a tracking generator and maybe the 'VNA as well, but where do I do my shopping?? If my 1st purchase transpires to be a clone what can I do ??? There ought to be a simple way for you to protect your products and the interests of those who purchase it. |
