Hello,
Thanks for the great video, it is very impressive and very well made.

I am also using the same ebay driver 3.2 w module that I bought for 7 euros on AliExpress.

1),I noticed that the Gain in the 160m band drops by about 3 dB compared to the one on higher bands. Did you experience the sane issue? Is this why you replaced the 2 native chokes by some 220uh ones?? If you could post a picture of the modified board so I see better how you have done it, it would be greatly appreciated.

2. could you also describe a little bit more the added value of the RC feedback mechanism you added to the module (with the value of the components). I noticed that the Gain of this little Power module is quite high, around 45dB and quite flat over all HF bands (apart from the 160m band where it is about 3dB lesser), so I wonder what is the purpose of adding this feedback network. Again a picture would be much appreciated

Best Regards
Peter
