El vie, 24 feb 2023 a las 13:50, Erik Kaashoek (< erik@...>) escribi¨®: New FW release
Version V1.4063, Ultra only
Changes:
- Option to sound a beep when the trigger level is exceeded.
- New measurement: MULTI BAND
- Waterfall height reduced.
The multi band measurement allows the definition of up to 8 bands to be scanned, each with a possible trigger level
The active bands will be scanned in the order as listed.
As the scanning is intended to be as fast as possible the RBW and display points are automatically optimized for speed depending on the span of the band.
There is not enough free memory in the 2.8" tinySA to add these functions.
The wiki is not yet updated with this new functionality

Re: tinySA deeper case back, larger battery, 3.5mm jack for Listen mode
Very nice. Are you willing to share your two STL files?

I wanted to change to a larger battery (1500mAh) and add a 3.5mm audio jack so I designed a new back case in DesignSpark Mechanical and printed it in PLA on a 3D printer.? I also 3D printed a protective cover.

Sorry, the links are in error due to having to correct the file names and then replacing the files with the files that were renamed.? The files you should look for are:
- TinySA Ultra Menu-Tree Chart - v1.4-49 - Updated February 23, 2023_V3.pdf
- TinySA Ultra Menu-Tree Chart - v1.4-49 - Updated February 23, 2023_V3.vsd
Just go to the Files section and sort by date so the latest files show at the top of the list and you should see them.

If you run any of our HTs through the "safety" applications from FCC or RSGB, they fail when the HT is hand-held next to the head.? Does anyone care??
Even the public responders and enforcers are exposed to identical levels of RF exposure.? Does anyone care???
Virtually all our cell phones and smartphones have a warning in the User's Manual (which no one reads) to hold the unit(s) several to 10 cm from the ear.? Does anyone heed this warning?? How could they as they don't read the User's Manual.? Does anyone care???

Hi Rob,
If you are standing that close to such a powerful source of RF or interference, you may also have to consider health issues :-)
It's always sensible to play on the safe side and start with an attenuator connected. A small 20dB attenuator, rated at 1 or 1/2 watt with SMA connectors would be a good starting point. At higher power levels attenuators begin to become quite large, but I find that a 20dB attenuator rated at 100 watts to be probably the most useful in the workshop. This brings 100watts down to a more manageable 1 watt, that allows the use of additional smaller 1 watt attenuators as required.
The TinySA already has a reasonable dynamic range, so as long as you don't exceed the recommended input level, and are using it in conjunction with a relatively small antenna, then you should have enough in hand to be able to differentiate between the strongest and weakest signals you are ever likely to encounter, unless of course you are standing right next to a transmit antenna.
Regards,
Martin

At times I have high noise level on 80 meters. ?I thought the TinySA would help me find it but I saw nothing until I built the impedance-boosting circuit. ?With this amp added to my TinySA,I could see the noise and walk right up to the house where it came from. ?They¡¯ve got a new ceiling fan that puts out a hump of noise every 30 kHz. ?We haven¡¯t figured out what to do about it yet, but at least I know where it's coming from.
I built and tested several extra boards and I¡¯ve been selling them for $24 including the battery and shipping. ?My PayPal account name is? wb2jlr@...?if you're interested 73, Rich?

I use these and they work well and are quite accurate.?

Rob,
To handle the 5W HT, you should use a fixed attenuator capable of handling the power. If you also have a step attenuator, they are never rated for more than 1/2W, sometimes less. So to get the %w down to 100mW or so, a 20 dB fixed attenuator will do. If you want to use only the fixed attenuator with the HT, you need to get the power down below 10mW to keep the Tinysa protected, so a 30 dB attenuator will do. I have seen step attenuators on eBay.

Hello,
I am a new Ham. Just purchased Ultra. One of the use cases I will use is for RFI finding.
Any one could suggest a small portable attenuator? How many levels would you suggest?
If I am standing near a power line with a magnetic loop or 2m or 70cm Yagi, how much "power" can I expect from the antenna?
Can I connect it to Ultra directly and not worry about damaging it under all cases of RFI / Power lines?
While we are at it, I like to use it with any 5W HT. So it should handle that power. But I think that might be overkill since the switchable 5W attenuator might not be small.
Perhaps someone has a schematic that I could build?
Suggestions are welcome.
73, everyone :)

The ultra is not an SDR
Hi Erik, That was the distinction I was trying to make between the two. Using the TinySA as an item of test equipment. I think the ability to plot signal level vs location would be a valuable addition to the tool set. If the TinySa is not able to do this itself, but an app was able to log signal levels and positional information, and then be able to export it. For off-line processing and further analysis in another application, or even by using something like an Excel spreadsheet. It would be able to compete against some very expensive professional tools, that actually don't do much more than this. Regards, Martin

At the moment SDR Angel will not support devices like the TinySA, but you can use any of the devices listed as being supported on the SDR Angel website, and that includes cheap RTL dongles. It may be possible to ask the SDR Angel developers to incorporate some method of importing raw data from a TinySA. But it's not really what SDR Angel was intended for. I think a better option would be for the TinySA app to incorporate a similar heat mapping function. As it is likely to be of more interest to the TinySA user base, as the commercial equivalents, that are typically used for the validation of transmitter coverage area predictions, or checking Cable TV leakage compliance, are outside the finances of most 'hobby' users. I guess a lot depends upon how many people would actually be interested in such a function, and if the app developers would be prepared to consider incorporating it. Regards, Martin

no doubt such equipment exists. No one is questioning that :) could you please point me to a cheep solution that is ¡°good enough¡± for everyone to report most common RFI issues and perhaps produce open street maps or any other maps displaying FRI?
I have asked the SDR Angel developers to produce an additional plugin that will do just that. It was only formally released a few days ago, and I haven't had a chance to set it up yet, but it does look promising. You can use it with one of the common sdr's in conjunction with a GPS receiver that can provide co-ordinates in NEMA format. Something like a cheap USB GPS/GNSS dongle should do the trick, as long as the interface appears as a COM pot and can support 4800 baud rate.
