Comprei um megir drum roller e estava +1,5 seg dia. Retirei o cristal e fiz a aferição 32.768.020 😮😮😮. Fiz os cálculos e coloquei um cristal 32.767.400 e ok 👍

the advertisement for this watch is that it uses a Taiwanese quartz module. is that true?

Problemas: 1- o equipamento de aferição tem que estar 100% calibrado 2- retirar o cristal do relogio e colocar em 36 graus se for de pulso, se for despertador fora de pulso deixar em temperatura ambiente 3- ter um oscilador com amplitude 100% aferido 4- conseguir bons cristais 5- cristal 32.768.100 é um otimo cristal mas vai adiantar 8 segundos por mes 6- cristal 32.768.500 vai adiantar 30 segundos por mes 7- 32.768 não serve de referencia 8- o c.i divisor de frequência dos relogios tambem sofrem desgaste. Eu tenho um despertador de 30 anos e adianta 1 segundo por dia com 32.767.900

Thank you for your vidéo, very nice.

Thanks for sharing 👌

Can you show the TTL to RS232 connecton to the MAX3232 mini converter board? I worked with the MAX232 chip years ago when I configured my Icom radio to RS232 and I am now confused as to how to interface the chip. 73 WA2SST

Hi, what capacitor is used?

Scusate ma radio frequenza la può fare

Как-то настраивали HC-05 дополнительно?

Saludos de acuerdo a cuantas estacionaria mete tu medidor SWR O ROE YA LO CHEQUESASTE👈🖐 SOROATRONIK el video en youtuve EL COLEGA TIENE UN VIDEO Q TE PUEDE INTEREZAR COMO ESTE DE LOS INTERRUPTORES Q TAMBIEN METE ESTACIONARIA DE TU VIEJA ESCUELA ACORDARTE DE Q TODO LO Q LE METES A TU RADIO TE SUBE COMO ESTE INTERRUPTOR DE LA VIEJA Alma MATER CON EL ADVENIMIENTO DE LOS MEDIDORES NANO VNA LO MISMO Q LOS DOMMYLOAD METE UNA CHURRADA DE ESTACIONARIAS SERIA SÚPER BUENO Q LO INDAGUES SALUDOS DESDE PANAMÁ

How to update to a higher version? Ex.V21.4 ​

Look at your pin,s rs-232 ?? if i look in te manual yaesu 991a than yaesu mention pin 3 input , not pin 2 ???you speek this and do that. , help pls , thanks for the good video

Perhaps it's a TCXO (Temperature Compensated Xtal Oscillator), which may use (basically) phase 'jitter' or little frequency steps to keep the average frequency exactly on the mark. ...Maybe... Maybe not. 🙂 73.

Hi, because I have the same radio I immediately thought that if someone don’t want to open up the radio there’s an easy way to do it. Just access the normal user menu. Can’t recall which menu item but is called “freq adj” or something. You have a narrower range but still… for small alignments is doable. Anyway, very good that you calibrate your radio in frequency. So many hams are out of freq. 73

ХЕРУРГ.

I speak a little English, but I understand this very interesting and good maked video. Thanks!

That was quite interesting, I have just completed a Sony TCK611s and notice that the belts I ordered were oily like tacky. And there did seem an un-eveness on the capstan flywheels which I kind of let go thinking it was just the nature of the belt as well as the tape deck having sat around for years. But then the elastic in the mode player whind up pulley began giving issues. This was the belt just not capable of reacting to the expansion and contraction of the Mode motor changing directions.

Excelente trabajo. Hay otro modelo que tiene un att de -20dB y mide la potencia. Seria muy bueno poder hacer una entrada de audio independiente y poder ajustar la DEV. LU3MKH 73

Fantastic video!

its a very good idea with separate battery casing

Those GPS modules typically provide a 1PPS discrete that could blink an LED to indicate reception. Two colour LED might be used for subtle combined effects, power and signal in one. Best if blinking was subtle.

Where did you get the module from

That was good investigative tech work! Thanks for sharing! The only thing I would have done different: set the power levels to 10w, 32w, and 100w so the s-meter is evenly divided as the powers are increased. Each power level increasing by 5db, which is almost an s-unit. For me, I guess I would have used 4w, 20w(for 10mhz),100w - each power level 7db apart and a very even progression up the s-meter and quieting of the receiver at the other end. Thanks for another great video - helping empower dx-sr8 owners! Oh! By the way, congratulations on owning a Dx-SR8 - they are great rigs at a decent price point.

Nice video my friend, What was the little board you had in the video when you first install the GPS? I have try to make my GPS works but I didn't know about that converter. can you please send me a link about that little board? 73 de PJ2SM. Thank you for your videos!!!!

Wow! I Admire your courage!... I´ll cosider to do the same with mine!, Thank you for share.

Perfect match of the housing to the cover. I like that you took your time and the rig survived it without a single scratch.

My radio was much clearer in sound.

Nicely done!

you have confused ferrite toroid and iron powder toroid. Iron powder toroid uses metal dust mixed with epoxy ,with low metal dust densityso it is not as hard as ferrite.

Man you can make the plug-in gps nodules for selling it!

Mate it is definitely the good add-on to the radio, however i think it have to be installed on the back side. Also have to be possibility to turn it off and the LED will eat your eyes during the night use :) IMHO!

What component are you actually tuning. VR120 or another part

My radio only puts out 49w on full power, brand new right out of the box. I know the radio is a few years old but it was never taken out of the box until I received it from a friend.

dirty semiconductors, lol

Congrats mate! Nice soldering iron!!!

give him enough time and he will destroy that helicopter and kill himself and anyone that's on board.

he left in too big of a hurry. you should lift off slowly into a hover and then proceed.

Tried to programme ist with a pickit2 - but althought the pickit is detected by my PC the pickit itself does not detect my "PIC16F1938". Neither in Windo$ nor in Linux. In Linux I can at least try to read the "PIC16F1938" but all I get are zeros. (pk2cmd -PPIC16F1938 -R -J -GE00-3F and pk2cmd -PPIC16F1938 /GP0-F) So I did not dare to write my modified hex file back onto the "PIC16F1938". Lucky that I do not know the Linux command for writing to hex file to the "PIC16F1938" 😁

May I commend you with your video production and I would like to ask you ask a question . Do you know if it is possible to mod this atu to accept a remote tune connection compatable with the Icom IC705 ?

That toroid made me shocked

Awesome project. Can i ask how i can find the trim capacitor and the crystal quartz on ali express? Search words, data values etc.?

Speed of the rotation will jump due to difference in thickness and sound will swim :)

thanks, i see that i should not buy a cheap chinese watch?

is the crystal expensive? i wonder why skmei did not install it like that when new ?

Hi guys, thank you for your comments. I will experiment with both of them, and then decide which one works better for me. If you want, I will let you know how it goes.

Where did you buy this box?

A good idea. One option would be to use a DPDT switch and send the unused antenna either to ground or through a 50 ohm resistor. That'd prevent noise and leakage between the two antennas or, if the switching is between two transceivers, RF from the hot one from getting into the other.

Ok, where did you get the manual for tunig the kit with the pickit?

Лампочку 12В в разрыв провода заземляющего сигнал добавь. Будет как контролька наличия питания на сигнальном проводе но при этом так же заземлялка...
