tinySA Frequency Correction

Short video demonstrating how to measure and correct the tinySA output frequency. You will need an accurate frequency counter to do this correction.
For more info go to tinySA.org

I really don't know what people expect from something under $70 but this is an amazing little box and I love both of mine!!

[@98xjdriver]

Very straight forward, I'll be trying this soon, I have a fairly good HP counter and a GPS DO to check it against before I run through this process.

Hi Erik. Great video. One question: where did you buy that little RF amplifier, to beef up the signal for the counter?? Thanks in advance for the info!!

[@ErikKaashoek]

Many available on eBay

[@JohnHill-qo3hb]

Yes, thank you Erik, this is a wonderful little box.

Hi Erik, I tried to follow your frequency correction but when I input correct frquency, I made mistake by clicking Mhz rather than Hz. After then, my tinySA doesn't generate detectionble signal at all. I tried to use factory defaults already but it didn't work. Would you advise me how to revive SG function?

[@ErikKaashoek]

Make sure you have the latest FW installed. Look here: tinysa.org/wiki/pmwiki.php?n=Main.SETTINGS3 and use the CLEAR CONFIG command You have to do a touch calibration after clearing the config. In case of problems read this: tinysa.org/wiki/pmwiki.php?n=Main.FAQ

@@ErikKaashoek many thanks for quick and kind asnwer! I really like TinySA to use for my tube radio repair and maintenace. It's both amazing and accessible tool~

[@jazzncofee3871]

@@ErikKaashoek finally I suceeded in frequency correction and huge thanks for the advice!

[@JohnTarbox]

Thanks for posting this, very useful information.

[@dummyload5648]

is this freq counter really precision? best to use complex with sdr radio and freq/time standart radiostantion?

[@ErikKaashoek]

The counter resolution is 64 Hz in high range, sufficient for tuning the tinySA

TNX Eric !!! 73 N8AUM

What do I need to do to be able to analyze frequencies between 100khz and 200khz with Tinysa by detecting them with a telescopic antenna?

[@ErikKaashoek]

The telescoping antenna is way to short to effectively receive such low frequencies. You will need an antenna of one quarter of the wavelength for effective reception. or you use a loop antenna, possibly with multiple turns, and an amplifier. The telescopic antenna may work with a 30dB amplifier.

[@ahmetozdemir7173]

@@ErikKaashoek Do you think the mini active whip antenna would work? It works between 10khz-30mhz.

[@zeljkoadzic1692]

hi can you tell us model type of amplifier PCB

[@ErikKaashoek]

Any of the low noise amplifier modules you can find around $10 on eBay will do.

[@АндрейДенисюк-ш7п]

The question is where to get calibrated freq counter. I think we could zero beat against 10MHz time signal with some effort, don't you?

[@ErikKaashoek]

Use a signal generator and zero beat it to the 10MHz time signal using a receiver and then use the tuned 10MHz to calibrate the frequency counter.

[@johnk9895]

That technique will only get you within about +/- 10 Hz at 10 MHz (+/-100 Hz error at 100 MHz)

[@skylabby]

Thanks Erik.

[@kantarjiev]

Where to get that frequency counter? Tnx.

[@ErikKaashoek]

Search eBay for "8 digit counter"

[@WanderLucioGomes]

Now that I got to understand how to calibrate, because I thought that these 10MHz that I would be seeing during the calibration, would also be corrected, but these 10MHz don't go through the calculations. exact?

[@ErikKaashoek]

Indeed

[@Ibelieve218]

i have no way to calibrate the high side?

[@ErikKaashoek]

Low and high side use the same calibration
