    Hello, can somebody help wich transistor is like bfg520

    I remove lpf , so now tuning to transistor q2 is from 88 to 108Mhz, is okej now to build, normal when i change the value of varicap i get those result

    Hello, can somebody help wich transistor is like bfg520

    Sorry one more question, how m Hello Audioguru if i wanna change my varicap voltage i can get this result from 76 to 97mhz, BUT NOW AT THE OUTPUT OF Q2 is going from 88Mhz to 108Mhz, when i change the varicap value, is right now?

    Hello, can somebody help wich transistor is like bfg520

    I change the varicap BB515 now is rom 89Mhz to 101Mhz, if its okey local oscillator, so you think is ok, soi gonna buid tomorow(i hope);)thnx for help:)

    Hello, can somebody help wich transistor is like bfg520

    Yes, i put the probe to the cathode of varicap, and i change to voltage...the tuning is from 90 to 100Mhz? is that normal? of what i have to do, i try also with BB515? but is not working

    Hello, can somebody help wich transistor is like bfg520

    Sir i go to sleep, but now stay the problem in the tuning, i dont know what to do of like that is normal, what do you think? goodnight.

    Hello, can somebody help wich transistor is like bfg520

    Because that sir he make the same, and i make mistake, i was looking one more time his schematic, after i change like him, i just add C10 also, i make experiments, and i did it, now i have only the problem with tuning, i put the voltage probe to chathode, i just change 90 to 100 i think, you...

    Hello, can somebody help wich transistor is like bfg520

    I make to work my circuit is working perfect the filter and everything, just one problem if you can help me, i can change the frequency from 90 to 100 this my pronblem now, can you help only with this also here my schematic

    Hello, can somebody help wich transistor is like bfg520

    Is orginal you circuits, you think software problem?

    Hello, can somebody help wich transistor is like bfg520

    look this one i make mistake i forget to connect 47P in serie with varicap, i dont know what mistake i make now?

    Hello, can somebody help wich transistor is like bfg520

    Thnx for explain, but i make the circuits like yours in -#71

    Hello, can somebody help wich transistor is like bfg520

    HELLO, i build the filter the same problem like min look the circuits

    Hello, can somebody help wich transistor is like bfg520

    Hello sir i think i ask you of i forget, the what DO the resistor 100m, why he dont work from 88 to 108mhz, how can i build, because like i said my circuits he dont work i want to use yours like said maybe the mak mistake, i understand you now

    Hello, can somebody help wich transistor is like bfg520

    One more time me, why you use that 8ohm resistor in serie with inductor?
  20. M

    Hello, can somebody help wich transistor is like bfg520

    Hello sir, i build your circuit is working perfect, but also mine old circuits is working perfect, the problem was only filtes, so i just remove all filters and now perfect is working....
