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) ----------------------------------------- From: K8tp@...To: [email protected] Cc: Sent: Wednesday August 25 2021 4:25:28PM Subject: [tinysa] Can't update firmware I've downloaded dfusedemo, version 3.0.6.

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
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. S. |

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.

Re: Attenuation for microphone check
¿ªÔÆÌåÓýNot 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. On Mon, Aug 23, 2021 at 8:53 PM Jim Shorney <jshorney@...> wrote:

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.

Re: Firmware update

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