Title: interesting problem
Post by: schwartz84 on January 13, 2012, 04:11:49 pm

hello ! i've built this http://pira.cz/gallery/show.asp?i=58 . i sold this transmitter to someone and he tell's me that he connected the exciter(without the 100w RF amplifier in the picture) to a 300w arf amplifier and this exciter i have built by PIRA schematics oscillates.is that possible?i don't think so.why?because i had connected this exciter to the RF amplifier 100w in the pictures in the link and works like a charm.i'm waiting for your opinions.thank you

ERM.... you need to calrify your question there sir... OBVIOUSLY IT OSCILLATES!! It's an oscillator (or has one in it!). Do you mean that the amp oscillates? Or there's audio issues? Let me know what you eman, describe the problem!
