FWIW, I tried this mod in a 2016 Cobra 29 and I'm getting 7 watt DK, with a steady 20-22 watts on voice, and 28-30 watts max pep with the stock driver (4 turn with core). I don't have the tool to tune L17 yet. Thank you for posting up this recipe, Sir.

So, L14 needed some tuning, 24-26 under modulation now from an 8~ d.k.

I Guess the question is is it maybe just a misprint about the 3mhz transition frequency? Maybe it's supposed to say 30mhz. Has any actually tried them? I know that I tried the hg1969 and it didn't go well in a 29 with the tip120 mod they usually fail catastrophicly! What about the cb20? In the same scenario do they work well?

I thought of a misprint. I'll have to order one and give it a whirl. They're $10 to us in .ca, but rather part with that than trust an ebay fake.
