Especially so when (AFAIK) the person who doesn’t know what he doesn’t know hasn’t yet got in his possession an example of the actual instrument that is being discussed! Often “less is more” IMHO. Peter

In a thread about the antenna attachment, I thought you said something about the antenna being a potential (no pun intended) ESD risk. Can you fill that in a little, please?

All tinySA Ultra have always had ESD protection
Happy you do read the wiki :-)

Basic or Ultra?

Good morning,

I recently purchased a TinySA and went through the first use steps and updated the firmware using the STM32 windows application. After completion I power cycled the unit as instructed and I am getting a grey/white blank screen. It will not reconnect because it is no longer in DFU mode.? Any suggestions would be greatly appreciated.?

Jason?

As Erik is the designer and Hugen is the maker (AFAIK) it’s pretty certain they will always give the right answers!

Remote diagnosis is always an iffy proposition, hence "almost certainly". Missing some crucial piece of information, an otherwise good guess can come up with the wrong answer.?

I have to admit the screen and hand sizes went sailing right past me. Between the bogus artwork and the selling price ($139 at R&L), there are red flags in plain sight.?

Camil Direct just sent me a note full of apology. A day late and more than a dollar short... >:-(

Ha, that's just a viewpoint from your 'perspective' :-)

Here's an easy question for ya'll.? In the Wiki FAQ it says about ESD protection "Make sure you have FW v1.3-3 or later. Go to CONFIG/VERSION. If the last line of the displayed version info is "ESD protected" the diodes are installed."

My vendor was Seesii via Amazon and unit was purchased March 15th.? I've updated the FW to the current .156 and it passes all selftests and calibration so hoping it's not a clone.? I look at the last line of the version info and don't find the ESD Protected.? This is the version screen.? I'm assuming it's not ESD protected.? Why were the protection diodes dropped in the later HW versions?

Thank ya'll for all the info I've learned from this group.

Seriously, Erik and Hugen's answers are almost certainly the answer to your question - not a clone, just dinged, but repairable. Best of luck with the surgery!?

There are companies in the US who do this as a commercial venture.? They also have the wherewithal to perform the required near-field to far-field transformation of the data - without which renders meaningless numbers, even in pattern strength and directivity.

They have to pay for very expensive waivers and jump through hoops to allow for flight in non direct line of sight (LOS) situations.

You do know that it is illegal for a non part 107 sUAS pilot to fly in a non direct LOS manner, correct?? To be clear, we're not talking about radio LOS - If you can't see the sUAS with the unaided eye, you are in violation.? Only a part 107 pilot with a waiver can operate non-LOS.

The FAA actively monitors the interwebs for such violations, and actively pursues those who violate the laws pertaining to "drones" (sUAS) nowadays.? There's been too many stupid people operating the aircraft in stupid ways as of late - and they've ruined it for everyone who never did, including your basic RC airplane/helicopter enthusiasts.

It is failing because you have two of COM4. This should not happen but the solution would be to map the second COm4 to a different port number.

With this in mind, it would be really useful if the TinySA app could take in real time GPS NMEA data, and create updated log files with time, date and position stamped signal level or plot file information.

A portable wideband HF active antenna could be calibrated to give the necessary antenna factor (needed to convert dBm to field strength). I haven’t got around to making/calibrating such an active antenna, but it’s not particularly difficult.

I have used a high impedance "E-Probe" type amplifier with a 1m long whip, fitted to a car roof with a magnetic mount. The intention at the time was to build a cheap drive around VDSL interference measurement system. But with fibre to the home now being rolled out, it doesn't seem to be such a big issue any more. However, EEV vehicle chargers may be the next problem.



I calibrated it using the Equivalent capacity substitution method.

You can either calculate or measure the whip capacitance.



And then use the Equivalent capacity substitution method to obtain the antenna factor.

Thanks Rick. I guess the next question is obvious.
Does anyone have suggestions on where to buy the input switch XINLUDA XA17-G4K in the US? I checked my usual sources (DigiKey & Mouser) with no luck.
Cheers, Mike
