I finished the KXB3080 adapter today. Receive seems OK, but transmit power into a dummy load is only about 0.2 watts on all bands. (It was about 3 watts with the KXB30.)
I suspect a short somewhere because Q6 gets hot and TX current drain is above normal at 850 mA, but I'll be darned if I can find it. The voltages at Q1, Q4, Q4, Q5, and Q are normal. I;ve also done the mod to increase the L3 windings. I'll have a fresh look in the morning, but meanwhile, has anybody else seen this problem?
