The speech amplifier is a … Reply to rahul The transmission frequency can be adjusted using the variable capacitance C3. we may use crystal earphone but output very stong ,*danger for ears *, feels a series volume control with one the earphone leds absolutely nessecary e.g 50-100k. can it be increase by using larger wire? L1 make copper wire?indutor col with the value 200uh?and this transmitter range pls and on transmitter how mw,sw? Like a heat sink atached to the transistor? The circuit may not be working at all . Python 75MHz AM Radio Transmitter (No Receiver) Vintage RC. C1 is decoupling capacitor.

4.4 out of 5 stars 327. sir please explain the working of the there a mix up int the explanation?it is written that Q1 is the oscillator and Q2 as the amplifier??

That means only the amplitude of the waves gets changed but the frequency … THANKS. /M-E. Hi Linta the range may be between 100 to 200 ft. You can use a roof top diagonal antenna of 100ft in length with (seven strands wire)the transmitter.

Online shopping from a great selection at Home & Kitchen Store.

?how many tuns?? Before feeding any signal to transistor base, the signal is decoupled so as to remove any noise present in it, if any. We have many posts on FM transmitters, so we decided to make one on AM transmitter.

There are two types of transmitters; FM & AM. Also I used 10uF for C5. your formula does not have n number of turns of coil. - 14oz Stainless Steel Travel Mug, Silver, #am - 11oz Ceramic White Coffee Mug, White, got am? This formula is a close approximation for coils having a length equal to or greater than 0.4 d. Forgot: is it ok to change the 500pF to 40pF???
