This is a guide to build & improve this $14 DIY Ebay kit as the OEM docs (also incl. here) are borderline Chinglish.

Could you possibly post the LT spice file?

Looks like a complete and lucid hack discription.  i ordered one and intend to do your mods. I didn't read where you used the amp or what you used it on.

My bitx 20 has 2 IRF510s for output for about 8-10 watts.  Would I better off taking power from the stage before output, rather than trying to turn down to such a small output? Or is there another way (attenuater of some sort?)

Thanks
