FM TRANSMITER 5W BY SATRUN S-083

[andygaz21]

sekedar informasi itu letak kaki kaki transistor BUFER C2053 X1 & C710 X10 nya Kliru. tapi yang di ocilatornya udah betul. trus itu hasilnya tidak sampai 5W gaz

 :-\wah  jadi inget jaman smp dulu karena belum tau cara ngukur transistor pernah bikin pemancar ini nyampe berkali kali kebakar terus hikz..(tapi untung masih murah jaman dulu tr nya) sangat memalukan

[rubel]

dengan paralel 4 TR 710 apakah meningkatan watt ?? @andy

[andygaz21]

Itu rangkaian meski kamu rangkai dengan betul match output gak sampai 5W paling cuma 3W.
selain itu frekwensi yang di hasilkan lumayan setabil. trus untuk mendapatkan out yang agak gede di bagian final bisa di tambahkan C1946 out bisa mencapai 25W oya jangan lupa kasih juga LPF biar gak nyamber ke mana mana

Thank you.

Hello
You ...  andygaz21  ....  Circuit this .....Sending out 5 watts or not.  I wish sector RF.  Because I do not buy a 2SC1971 transistor.  C710 is not a transistor  RF.  Please confirm,  have  picture of this  circuit or not.  (Assembly is complete) ...............To reduce costs. Because it is expensive.

Thank you

Dear STL,
As described above by AndiGazz, this power output not more or less than 5 watts. in additional,the lead placement of BUFER C2053 X1 & C710 X10 was wrong (inverted)
As far as i know, 2SC710 was capable to operate at VHF area and ease to handling 108 Mhz.

at local shop here, the price of 1971 is nothing more than IRD.27500,- around US$3 each and I think its fair enough.

ni bahasa bikin pusing ni kepala

if you want to add a larger power transistor BLF278 MOSFET will be out 300W

neng merconiz masak transistor 1971 harganya 27500,- la wong di tempat saya aja 1971 harga mencapai 160.000rb-175000rb merk mitsubishi. oya ird tu merk dari mana kok saya gak pernah tau
