Holy cow! Finally a video of what I'm trying to do! I want to be able to detect rain/snow and intensity with no moving parts! Please tell me how you made this!

Dali je to neki repetitor ili?

4xz Israeli 🇮🇱 Navy

I had many QSO's here in Hungary on DSB, all my friends said this lil radio sounds not bad on their radios. I use the UV-5(8) orange display. Im very happy with it and the IJV 3.16 Firmware

any code and schematic to learn about it ? CA2RXU , 73!

i there i am living in India .. i can't tarack a balloon using auto rx .. it picks up the signal but it can decode .. i'am 1 km away from the local metro dep.. i did some research on local station I found that .. they are using rsg-20A radiosonde .. does auto rx decode it ? pls help

What is the signal transmitting

Great, 73 from Germany

Koji je to vrag?!

Ovo bi bio vrlo zanimljiv projekt, pošto do sada još nisam uspostavio niti jednu SSB vezu na 50 MHz. Jesam na FT8, ali bi želio znati kako mi radi antena. A band je konstantno zatvoren. Ili barem ja nisam uspio biti na pravoj frekvenciji u pravo vrijeme.

Neki dan sam našao slično na 1876 kHz (USB), neke informacije oko vremenskih prilika. Kasnije na 1883 kHz. Uglavnom, nije LSB, nego USB (Upper Side Band). Dosta je slab signal, pošto je moja antena teška improvizacija.

Ti baš nađeš svašta. Evo, i ja slušam tu frekvenciju. I nije mi jasno kakva je to modulacija, odnosno kakav kod. "Mijau, mijau...." :D

Dali je to isto MSK144?

Ovo je intteresantno. Na zalost još uvijek nemam UKV stanicu. Dali si slušao GRAVES na 143.050. Svakog dana imaš pingove. Stavi na recimo USB i malo pomakni frekvenciju tako da ti je 143.050 negdje na 1 kHz. Isto tako, prelet Starlink satelita ima interesantne refleksije. Nisam još skontao ISS, ali i on ima super refleksiju. Taj odašiljač (GRAVES) emitira svaki dan i noć. EDIT: Samo okreni antenu na zapad i malo podigni. Trenutno slušam na GP antenu, isto tako ide - čak i backscatter prima.

Nije čisti sinus. Moraš staviti low pass filter. Inače ideš gore na više harmonike.

Na kojoj je frekvenciji?

Moraš odblokirati i ostale videe. Htio sam te nešto pitati u komentaru, ali ne - sve je za djecu. :D

That is very strong signal. Which antenna on your RX?

How does it compare to Tx power in V/UHF? Too low?

I dig it. Do you have the amplified freq out going right into the speaker?

127 AM tx????

How

Tell me more about this…

I used HC12 baud 1200 100mW power with external LPDA. I can receive signal 12km away

in 27mhz or air band receives in Am, but if you activate Fm radio tbem has TX Fm in these bands.

How to decode that beacon from sdr? Please share the arduino code

Da prima samo jake i signale koji su emitirani iz blizine,softver zeza itd,treba vremena da ga poprave kroz firmware,ako budu htjeli,mada sumnjam.

Does it hear ANYTHING down there?

Hi there! It appears, you have mislabelled: it's ADC, which stands for Analog to DIgital Converter, of which the DAC (Digital to Analog Converter) is the opposite. The ATtiny13 is a really compact, useful chip, but it doesn't have a built-in DAC (but you could make one with a PWM channel and a low-pass filter, or an R-2R resistor ladder, up to 6 bits of resolution, or even more when utilizing shift registers, but that defeats the purpose a little bit). Keep on learning, because that's why we live! Congrats for fitting the code into 1K of Flash and only 64 BYTES of RAM! TL;DR: Please read the datasheet first, everything you need to know is in there! Best wishes, Greg (from Hungary)

Nice video, like it, thanks for sharing :)

I can even enter 11 meter band

Code

Interesting project

Cool. I want one.

funny

Good job!

What is the sound on reception?

Температура от датчика движения??? Rcwl.

Скетч???

but HOW?!

Good project

Please develop 12F675 push button led function change running

Got same thing today with UV5R on a pass where crew spoke to a school in Ohio.

Wow that was too fast...

Hi ! Looks like the first one is just a "standard" clone of the original frequency meter (without crystal tester) : www.qsl.net/dl4yhf/freq_counter/freq_counter.html. The "secret" menu allows customizing some frequency offset.

hola, esto es lo mismo? www.ebay.com/itm/ICL8038-Monolithic-Function-Signal-Generator-Module-Sine-Square-Triangle-DIY-K9/222315826544?epid=728634713&hash=item33c30e4d70%3Ag%3A~v8AAOSwcUBYKqw6&LH_BIN=1 gracias.

You're right. My rashness.

Why not tell the truth, 9K was no better than 439?
