Re: Can't update firmware

 

Hey Terry, I just upgraded two Tiny SA's (one older and one the newer version) to FW 1.3.317 with no problems. I did it this time with the TinySA-app using the applications built in upgrade function. Smoother that the DFUdemo. However, for previous versions I have used DFUdemo, also with no issues. If you aren't using TinySA-App (available at (), but are using the DFUdemo program, be sure you are using the "Upgrade" section, NOT the "Upload" section and have the correct .dfu file selected (can be found on the site above).?

I also believe that I did run into a recognition issue, a while back,with the DFUdemo program seeing the device with either the TinySA or the NanoVNA. I had to either connect the device first, switch to DFU mode, then fire up the DFUdemo program for it to see it. But if you can connect the TinySA to the PC (assuming you are using a PC), and it shows up in device manager under the COM ports, when you switch to DFU mode, the COM port drops and it shows up in?USB Serial Devices.

I'm sure some of the other guys on here will also respond with good suggestions...Good Luck....Ted (KD7AQO)

Subject: [tinysa] Can't update firmware

I've downloaded dfusedemo, version 3.0.6. With it running, I connect the TinySA and put it in DFU mode, but the application doesn't find it. If it's any help, when I enter DFU mode I get the 'USB disconnect' sound.

I've viewed a couple of YouTube videos, and can't figure out what I could be doing wrong. Also, if I click CHOOSE and select the new .DFU file, the application reports that the file doesn't have the correct format. Seems I have two different issues.

Re: Attenuation for microphone check

 

Thank you all for the replies, especially the links in the wiki that I did not realize was populated. We designed a replacement pre-amp for the D104 roughly based on W2AEW's preamp. It contains op-amps and two variable caps to set the bass and treble roll-offs. I want to check the output of the microphone as I adjust the pots.

Re: Attenuation for microphone check

 

...and by take the antenna off I am referring to the one on the Tiny SA, NOT the radio!? Hopefully you knew that.

Re: Attenuation for microphone check

 

Just put it near the radio.? There should be plenty of leakage to tickle the SA.? Be sure to set the SA for the audio range only if you are looking at modulation. If you want to test the microphone you would do that direct, not using the RF out of the radio.? You will still need a pad and possibly a DC blocking cap depending on who set up the mic. (It shouldn't have DC voltage on the wiring but do you know for sure it was wired correctly by a competent person?)

Take the antenna off initially and use input 1 to see the radio modulation.? You can measure it effectively without it being hooked up but you can see if you have a working mic and should see a decent audio spectrum this way.

Re: Attenuation for microphone check

 

You control power level with the mic gain control or the level of your audio source. However you will still want the safety factor of an attenuator or air-gapped dummy load.

Not sure what your exact intention is with a ¡°mic check¡± (this could be one of several things) ¨C however, one thing that comes to mind is to consider transmitting into a dummy load and then putting the TinySA antenna near the coax.

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.

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
