If i replace c75 with 22pF the power down to 1.2 w. If i replace with 100pf down to 1.8w. The original value of 47pF i like is correct. Note, the hfE of c2314 is 220. Is correct or low? The datasheet show max 3xx hfE

New info: With 4 turns L13 coil around 2.2w. If i remove c75 obtain 1w of power

I have see that the Midland 5001z schematic is similar to my station. I have make a fast search in google, and i have found this: http://www.copperelectronics.com/discus4/messages/3847/118418.html?1452960370 Can help me this info? p.s.: C75 keep or remove?

Ok, first i remove the 10k addition. The two capacitors swapped, keep or undo? I remove C72 out, with this capacitor installed, the power is down. You latest attached file is a schematic from a midland, it is correct? Before damaging L13, if it seems right, I will make a swap with another...

my l13 has 6 coil turns. if I add a slug, it decreases the power, it never increases. So should I change L13 for a 4-turn coil without slug? also, I undo the mod to add 10k + coil ?? An L13 with 4 turns can increase power from 2w to 8-10w??

Hello! It's late here, but I did a quick test before going to sleep. L13 has 6 copper turns. I have rescued a core from another coil, and I have placed it at 4 turns, barely 1w. if I loosen up to 5 turns 1.5w, if I take it out more or take it off 2w. This info can help?

After the latest changes, the power is around 1.5w, nothing more. If i try to remove again c72 te power ups to 2w, same power fron step 1, without 10k+rfc4. I need more help :)

I have reinstall c74 removed yesterday, swap c77 with c73, changed c72 with 330pf. Before install 10k + rfc4 the power output is around 1w. Less. I'm going to add 10k+rfc4, try, and after remove R78 and jump R79 (10ohm) and try again.

Step 1: reinstall L11: Power is back!! 2w power, i go to try step 2

First of all, sorry if I have expressed myself badly. I'm going to keep trying the latest suggestions that I have done to me, I have scored everything and this afternoon I try. I have not given up, and I know that my station is not the same as "charges 29". Perhaps the fact that he does not...

Thank you for responding and for all the time you spend on my problem. This afternoon I try to execute the changes that you propose to me now. I have saved all the components, I always do, if something does not end well, I will try to return to the starting point. Returning to my initial...

Thanks for answering. Before reading all this last post, I was doing the conversion. Before conversion, the transmiter delivered a power of approximately 3 watts. After conversion, zero watt. I have tried different IRF520s, I have tried different values of C72 and C77, I removed C75 from the...

Okay, I did not go into that detail, but I have the concept, I know that two capacitors in parallel add their capacity. Agree. Do I continue with your recommendation to add capacitors IN PARALLEL to C77?

Okay, thank you very much, I will carefully study all this information and try to solve my problem. I really appreciate all the information and your patience. :)

Thank you! how much information! I will read it a couple of times to understand it better. What values of C77 do you think I can add in parallel? Or rather, what maximum total capacitor do you recommend? I don't know if adding another 150pF cap in parallel will be too little or too much.

Just a detail Handy Andy, when the power was turned up to this station, they took the core out of L13. Can this go wrong for this modification? I don't have that core.

Yes, with dummy load, and also with antenna. Where another station gives 8W, this one only gives 2W. I have no equipment to measure RF, just a multimeter.

Hello, i have check the power with a watt-metter only. The station have tunned up to 8W years ago, but after use it with a de-tuned antenna, the actual power is around 2W Yes, i have a legit 2312 and 2166, from the Saturn 3900 converted to Mosfet. In good condition.

Thank you!!!! I just saw it right now! I did not receive a response notification !! I write it down, and I'm going to try it !! Thank you!!! So I keep the Driver and use an IRF520 as final, right? You have made my day!!

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...
