King Cobra PCB

[praktik_1974]

My project (copy) in DipTrace
The next will be a hybrid, DIP-SMD

[praktik_1974]

I perfectly understand that you give all the files for free... You also answer all the questions and conduct consultations... I am very grateful to YOU for this!! With respect!!

Can you get the PCB King Cobra?

my old channel was banned of angry bird youtub and all files were lost. i loaded this video now. i see you are not able to understand that i share ALL ARCHIVE OF FILES FREE,
this video from the archive. thanks to Eduardo again.

It's a pity that there are very few videos of tests on the ground...(( Maybe you have a link to the video? For example, like this...https://www.youtube.com/watch?v=7Zbsse3frUA

Can I replace DIP components with smd? For example, resistors 0805, and microcircuits in smd? Will it somehow affect the operation of the device?

yes, yoy can do what you want.

Will it somehow affect the operation of the device?

not. for example, Compadre is just a part of all king cobra schematic and working good.

Good day . KT315, why didn't they make this board on smd components? Maybe the characteristics will not be the same, or not the same? I meant chips and resistors. It is clear about the capacitors, there should be a film in the right places. Sincerely.

yes, Bounty Hunter 4 Legend + is in my plan. but FT is active live company. i can violate a law.

PCB received, looks beautiful. Could you give list of components rev.5. . Thanks greetings.

looks good... congrats you are in the Game now. you got wonderful Winter Project. get a fun!

BOM file

follow rules
1. do not solder tantalums at first. leave them on last stage, when you will get working state board.
2. do not try test in NOTCH mode in your room conditions, you will get a noise a source of which you are not able to find. you must test this mode just in a field.
3. you must tune a coil in ALL METALL mode. you must get ideal work at ground, then close the coil.
4. coil is same like TGSL coil.

L1 and L2 value 22-47+ uH, or, in case you will not find them, set resistors 22-47 Ohm.

tantalum place pads

JCL does the things very speedy... i hope to get new batch of boards in 2-3 days.

Yes, a multi-turn pot will make GB adjustment finer.
Good point kt.
