I checked with the built-in power meter - 0W at the BNC output, but 2.28W at the drain of Q3. Not sure whether that means there is RF, but a fault in the LPF now.
Steve,
You may see I've asked about this.
Your problem might be C29 or LPF but I'm wondering if the internal power meter might give an erroneous result on the PA drains. Many have reported 5W or more indicated (not necessarily accurately) on the drains.
