Ed, Could you turn on the COMM dialog box (click on the USB icon next to the camera icon) and copy and paste the error message that occurs when a disconnect occurs?? It will probably be the same

Erik, I am now running the TinySA App with the TinySA Ultra. This is the only app running and it has "focus". In this latest test it locked-up after about 5 minutes and disconnected. I set the app for

Thanks for looking into this issue, Erik! -- Ed, K0KC k0kc@... http://k0kc.us/

Can this be confirmed by other people seeing lock up? It only seems to happen when App does not have focus? -- For more info on the tinySA go to https://tinysa.org/wiki/

Erik, I tried to duplicate Ed's disconnect issue and could only due so after switching focus to another application.? When I switched back to tinySA-App (after a few minutes in the other application)

More intel...my original TinySA froze-up after about an hour of normal operation. -- Ed, K0KC k0kc@... http://k0kc.us/

Here is no real flow control between the tinySA and the App. Just big buffers As the Ultra is faster there could be a buffer overflow I did not yet detect I will do some more tests And the baudrate

Well, it looks like I spoke too soon! The TinySA Ultra froze-up after about 5 minutes of operation and disconnected shortly thereafter. The only way to recover was to turn the TinySA Ultra off and on

Wolfgang, Thanks for the suggestion...I should have thought of that myself. I did disable all power management on both computers and changed the baud rate back to 115200. I am currently testing the

It would nice to be able to enter 12GHz as a stop frequency? (for exploring the high band) in the TinySA App v1.1.20.1 max seems 9900 MHz.

I have used it for work at 11Ghz to verify the STL signal at one of out stations. Yes it is lacking sensitivity, but since our transmit signal levels are at -5dbm+-1db at full power at the test port

Ed, did you disable the 'power management option' of your USB port? If there is no traffic on the USB port, Windows will shut it down after certain periode of time. 73's de OE1MWW Wolfgang Google:

Colleagues, I have owned a TinySA for quite a while now and just received a new TinySA Ultra yesterday (the screen was aligned properly). The Ultra seems to be working well stand alone, but I am

For me, the biggest benefit of Ultra is that I don't have to worry about spur removal. The sensitivity of the TinySA at 10 GHz is not bad compared to a pro harmonic mixer, and when setting up radio

Thanks, so it's just like the old. -- Klaus, DL5KV

Current max freq for the Ultra is 12GHz. Not sure you will see anything above that as the Ultra will need to use the 5th harmonic and the mixer is used way, way out of spec. And I have nothing to test

I have home made ham radio transverters up to 47 GHz. I use an Advantest spectrum analyzer together with a harmonic mixer up to 100 GHz to set them up. When working with the harmonic mixer, I have to

Funny you should ask Erik.? I was gifted an X-Band (10.5GHz) Gunn Oscillator transceiver in unknown condition.? After hooking it up to a 9V battery I was able to verify with my tinySA Ultra that at

In the ultra there are multiple correction tables, if there is a 30 MHz point in the table it can not be removed and correction at 30MHz must be zero. -- For more info on the tinySA go to
