Wow! how many more amazing tricks can you make this brilliant device perform? A massive thanks for all the time, effort and dedication you have put into the development of the tinySA.
Useful video ! I actually didn't know at first that the basic TinySA could listen, but it thankfully does. It may not be the brightest way to listen to FM, but sure an unique one. I would assume you are the designer/creator of the TinySA and i would like to thank you for such an affordable tool. With great regards from germany.
Hallo Klaas, Fijn dat je dit met ons wilt delen man! Hartstikke bedankt! ja en nou krijg je natuurlijk zo iets van wanneer komt nu de tinySA met de optie tot luisteren, want jij bewijst dat het kan! . Nogmaals dank! VrGr Rob
I upgraded the firmware where it shows the choice "listen" in the "Level" submenu. However, I tried to connect a headphone as showed, but it does not work. Besides, checking with a scope I cannot detect any signal on the "red" spot. Any suggestion?
Do you see the signal using a scope? If yes, use a sensitive in-ear headphone. Make sure you first test with an AM modulated signal so you can tune on the signal, without signal you should hear noise
@@ErikKaashoek No signal detected with a scope (even at high sensitivity). No noise at all from the in-ear headphone (which I checked in advance as working). Maybe it should be connected at some other point? Btw I had to use an electrolytic as 100 microF capacitor. Tested both with the 2 x 10K and the 1 x 4.7K resistors.
Hello i am missing some informations: a ) what jack plug is needed here: stereo, mono ... ? b ) which impedance / earphone shall be used ? I tried earphones from my collection. Some of them seemed to cause shortcuts. I had to plug off half way to hear something. But it is not important, most signals are noise. I am using the latest firmware from 2024-01-10.
Thank you very much for this informative youtube just I want to ask about how to shift from am to fm? Second thing how to send a signal to another device from this device? Thank you again
is there an FM demodulator on tinySA ultra or AM only? Your next step may be to make sound quality to high fidelity so it may be used as a radio receiver and in additional demodulation modes.
@@ErikKaashoekit appears that malahit is the only model in the class with decent demodulator sound quality, but it has much narrower bandwidth. You may increase the price of the final product if you can make good performance, as it may be used then by radio amateurs.
I am a complete noob with a tinySA. I got my tinySA Ultra today. So I hope this is not a totally silly question but why is a FM radio station reception not best (89 to 110 mhz) when a waveform peak is selected?
For AM you should select the peak but as there is no FM demodulator you have to use the slope of the filter to do the demodulation so you have to put the slope of the filter on the peak, so tune to the side
Hi, if I were to replace the two resistors with a variable one, what value would that be? I have no knowledge of electronics, but I'm not afraid to solder, haha. Is there a technical drawing of the case? I want to make a 3d printed version (which I will happily share for free, of course) that accomodates an earphone jack, the stylus and maybe a larger battery. Which brings up another second question: Can the TinySA recharge a 18650? The last question would be: Can the audio be sent by software only to the USB for a USB to 3.5 mm jack adapter?
@@ErikKaashoek Thanks for answer. That is why I asked. I want to use microspeaker(8 Ohm) from dead M5Stack, and I'm not sure it'll be driven enought. Maybe ih future FW release it'll be possibe? At least any linear amp(LM386) may be used.
@@ErikKaashoek "@andilowe9526 I don't understand your question" I meant, is there a little built-in speaker in the TinySA or whatelse did you connected to the TinySA to hear the sound?

@@ErikKaashoek Erik, greetings from another Netherlander! My family immigrated to the USa from Overjssen in the 1870's. I have a matlab code to drive TinySA.

A massive thanks for all the time, effort and dedication you have put into the development of the tinySA.
Absolutely fantastic! I steered clear of these spectrum analysers simply because they had no audio, I couldnt hear the signals I was tuned to.
Great video. I am old enough to remember "slope detection" because FM demodulators were rare back in the day !
Zo ontzettend tof dat een nederlander, jij , dit ding gemaakt heeft, kudos!

Listen: BIG YESSS.
It makes a huge difference on how we can use the unit.
Please publish how can it be done!!
Thanks from Puerto Rico
Is there a way to have a noise squelch set to -X dbm ?
Is the signal output from the DAC active only when "listen" is chosen in the menu? And silent when not? Thank you for a great product!
Indeed.

@@ErikKaashoek I used the tinySA_v1.2-86-g6e72f45.bin file, from March 17 2021. Seems the latest.
@@ascaniosobrero Than I have no clue
Kun je hiermee ook naar VHF/UHF frequenties luisteren of alleen am/fm?
The AM and FM listening method is independent of the frequency. It should work on any frequency
Eric thanks for your reply another question is that what is the gain of this receiver i mean the gain of the tinySA
There is automatic gain control applied to the audio so not a single gain
Hello i am missing some informations:
a ) what jack plug is needed here: stereo, mono ... ?
b ) which impedance / earphone shall be used ?
I tried earphones from my collection. Some of them seemed to cause shortcuts. I had to plug off half way to hear something. But it is not important, most signals are noise.
I am using the latest firmware from 2024-01-10.
Stereo, highest impedance headset works best. Often the cheapest are the loudest
So to listen to FM You basically use AM Slope Detection?
Yes
I just received a TinySA Ultra.
Is this possible brand new out of the box? It had the menu option. I don't really want to mod it.
Did you notice the already present 3.5mm headphone jack on the side of the tinySA Ultra?
Thank you very much for this informative youtube just I want to ask about how to shift from am to fm?
Second thing how to send a signal to another device from this device?
Thank you again
Do detect FM you use AM slope detection which means you tune next to the signal and carefully select an RBW that has its slope directly at the signal.
@@ErikKaashoek if you could make a short youtube to explain that it will be highly appreciated.
Thank you
Then how do I know the number of channels scanned by my tinySA
Did you check the wiki?: tinysa.org/wiki/pmwiki.php?n=Main.HomePage
amazing! is there any way making it sweep while listening, so it can move the marker every time to the strongest frequency?
No, no sweeping is possible while listening
is there an FM demodulator on tinySA ultra or AM only? Your next step may be to make sound quality to high fidelity so it may be used as a radio receiver and in additional demodulation modes.
AM only, but slope detection works for FM

My TinySa Ultra not working with Audio. It just Freeze after i put "Freeze" on the Touchscreen...
Please join groups.io/g/tinysa/messages for support, I do not understand what you mean with 'i put "Freeze" on Touchscreen'
can any software save this signal that we hear through 3.5mm output, but by the usb that we connect to computer? I have Tiny Ultra
Not in any current sw
No, but you can connect it to a 3,5 mm aux to computer or phone as microphone connection and with lowered voltage.

@@ErikKaashoek excellent, thanks!
which version is your tinySA, thank you
I ordered one online, listen does nothing. How can I enable it
Please join groups.io/g/tinysa/messages?expanded=1 for support
Great! Erik, is there a signal(pin) that activated in Listen Mode? I want to use it to enable/disable audio amp, like NS4150.
Thanks in advance
No, the listen output is loud enough for a headset. Te NS4150 amp is class D so it may cause spurs if fit close to the tinySA

Is it possible to make all hackRF stuff into this tinysa?
I don't understand the question. The hackRF is a SDR radio/transmitter. The tinySA is a spectrum analyzer.
Is it possible that tinysa can be a function generator, so that you can copy the signal and replay it like HackRF?
@@jessishandsome No. The tinySA can generate a signal based on certain settings but it can not play back a wave form.
