hello there audio guru,
I have some enquiries regarding the types of capacitors and inductor which can be used for your fm transmitter. I'm trying to make a pcb out of smd components with pour copper to reduce em and also reduce high frequency noise.
The following are the trimmer capacitor which i plan to use:
**broken link removed**
The following shows the inductor that was planned to be used:
**broken link removed**
as for the ordinary capacitors, i would go for ceramic capacitors...any opinions or advice on this? would be advisable to make your own inductor? if so how can you ensure that it is the correct rating and how do i make it? [unfortunately i do not have access to expensive equipment to measure inductance
]
btw, how was tuning done using audio guru's fm transmitter? i mean how would you know which frequency the transmitter is transmitting at by tuning the trimmer capacitor? do i need to use a spectrum analyser to tune everytime itry and change the frequency of operation of the circuit? please do advice!thanx in advance
