Hi everyone!! I open this post to see if anyone can help me, although I fear it will be difficult. Excuse my writing, I am writing to you from Spain.
I started as a child with the CB, emulating my brother, and with the little money I had, I was able to acquire an inexpensive station, a Dragon CB-240N, which shares a circuit with the Memory 8012. Attached diagram.
We had a faulty stationary meter and used the equipment with an uncoupled antenna. I have rescued the equipment recently and it has very little power output, barely 2W, having at that time raised it to about 8W. I sense that it has deteriorated endings.
Years ago, following a tutorial, I converted a Saturn 3900 to mosfet, using the IRF520s.
Without a tutorial or instructions, I am unable to make a modification. I have knowledge in electronics, but not that much. I would like to repair the equipment and give it a little more power, without exaggeration. I have in my possession a 2SC2166, two 2SC2312 and several IRF520.
Would it be very difficult to modify my scheme to be able to use the two transistors, and gain a little power? or, failing that, use the 2SC2166 as the driver and the IRF520 as the final one. I am afraid that both the driver and the end of my station are damaged.
Thank you very much for reading the post and for your help.
