Transformare telecomanda masinuta de la 27Mhz la 49Mhz

Salut,

baietii mei au primit doua masinute cu telecomanda, evident ambele pe 27Mhz, deci o telecomanda controleaza ambele masini. In telecomanda este un quartz cu inscriptia V27145R, care cred ca e de 27.145Mhz. Teoretic modelul se vinde si pe 49Mhz, si ma gandesc daca schimb numai quartzul in telecomanda si masinuta  la una de 48Mzh (de ex http://www.adelaida....uart-48mhz.html), va merge? Sau daca aveti o alta idee cum sa rezolv aceasta problema relativ usor, sunt interesat.

Telecomenzile nu au buton A, B, C ?

Am patit si eu odata treba asta, iar rezolvarea rapida si de moment a fost sa "mesteresc" telecomanda si masinuta prin "modificarea" bobinelor. Nu mai tin exact minte ce si cum, insa parca telecomanda avea bobina cu ferita si era reglabila.

Fiecare banda (27, 49, 50 ..) are mai multe canale, cu frecvente specifice.
Va trebui sa folosesti un quartz cu frecventa adecvata noii benzi / noului canal.
Nu uita de receptorul din masinuta, va trebui sa mearga pe aceeasi frecventa cu telecomanda.

Daca sunt simple jucarii secventiale degeaba schimbi qz, circuitele trebuie reacordate in concordanta cu frecventa noului qz, adica schimbi si bobinele in tx cat si in rx ,pt asta ai nevoie de ceva scule si experienta in rf, pune niste poze cu obiectele in cauza.
Telecomenzile proportionale au cristale interschimbabile in aceasi banda , de pilda in 27 ai
26.995 MHz -- Channel 1 -- Brown
27.045 MHz -- Channel 2 -- Red
27.095 MHz -- Channel 3 -- Orange
27.145 MHz -- Channel 4 -- Yellow
27.195 MHz -- Channel 5 -- Green
27.255 MHz -- etc ,

dar schimband qz in emitator automat trebuie schimbat si in receptor , in banda de 27 nu poti pune qz in 35 ,  40 sau 72, totodata trebuie sa-ti fie clar in ce fel sunt modulate, AM sau FM deoarece qz AM nu sunt compatibile cu FM chiar daca sunt in aceasi banda !!!

Cand cumperi 2 masinute intotdeauna verifici sa fie in benzi diferite daca vrei sa mearga simultan, nu prea ai ce sa schimbi la ele...

Am desfacut numai telecomanda. Atasez o poza cu circuitul.Evident as schimba quartzul atat in telecomanda cat si in masinuta. Nu tin neaparat sa schimn in 48Mhz, e ok si daca ar merge cu ceva apoape de 27Mhz, din tabelul din sus de exemplu 27.045 sau asa deva, dar nu stiu daca e de ajuns sa fac aceasta schimbare,

In nici un caz, dupa cum ti-am povestit mai sus trebuie refacut acordul circuitelor rf ,nu e o chestie pe care o faci doar cu surubelnita si pistolul de lipit !!!
Ambalezi una din masini si o schimbi la magazin cu una in alta frecventa .

Inteleg. La o alta masinuta era cum scria florin71_skoda, erau ceva bobine unde puteam regla sa nu fie pe acelasi frecventa, spera sa fie si aici la fel, dar nu era. Si dupa aia speram ca schimbarea quartzului e de ajuns.

@andreic: nu eu l-am cumparat, au primit cadou de la cineva care venea din SUA, deci nici nu pot s-o duc inapoi.

Indiferent ce quartz pui si acordezi, in aceeasi banda o sa tot fie interferente ca sunt apropiate ca frecvente si semnalele astea de trelecomenzi au banda destul de larga... ideal e in benzi diferite.

Engleza nu e o problema, mersi. Dar nu cred ca merita, nu e nu stiu ce masinuta. Se numeste Blue Hat Thunder Tumbler, pe Amazon e $17-$30 https://www.amazon.c...k/dp/B005Q9BCU2 .
