hi,
I have corrected my mistake and put the transistor in its correct polarity and now tsa5511 locks the frequency and the transmitter works (must be taken to be learned).
after my test, it turns out that it does not lock above 98 MHz with frequency of my conpteur I see it oscillate around 99...
HI ,
I think I found why the oscillator does not work and if I'm right I'm an idiot for not having thought .
As I said this is my first fm transmitter and in addition I chose a pll version, so this is a big first for me in the use and welding mosfet has 4 pins, thereby for the implementaion of...
hi,
i have just check if there is a on ascillation on RFIN1 of the tsa5511 and i can't get it on my victor 3165 frequency conter
maybe the eco not oscillate but i don't know why!!
i use bf981 mosfet transistor and bb809 varicap
maybe the polarity is wrong but i don't know how to chek it
I...
Hi,
thank you for taking time to help me.
regarding the scheme, what I mean is that any partial order part is missing on this one, but the whole party and oscillator amplifier is complet.Je board not found another diagram of the rdvv300 full internet and the link provides the issuer does not...
hi,
I recently made my first FM pll transmitter Rdvv 300mW found here: http://www.3-mtr.info/shareware/RDVV%20300mWatt
The pic, the buttons, the lcd are working but the TSA5511 chip cannot lock, the led are not activate and on the lcd stay on "busy"
i have double check the board before solder...
