I've recently built the Backpacker II 40m QRP kit from Tejas. I enjoyed
building the kit, and have been impressed with the direct conversion

type of design).

However, the VFO has a low output - approx 0.1v pk-pk after the NE602 mixer
compared with an expected (manual) 0.5v pk-pk.

I've tried swapping the MPF102 VFO to see if the o/p is dependent on that
device - no change.

Any hints/suggestions/experiences with the Backpacker II would be welcome.
