How do rigs degrade with degradation of supply voltage

I am curious as to how rigs work with lower power supply voltages. I am
planning of building a small rig for a 50 mile back packing trip next
summer. In the past I have had trouble with transmitters becoming
unstable or unclean when the battery voltage declines. I am planning on
using alkaline cells because I believe they have the greatest energy
density.

What I propose is for some of you to hook up your favorite qrp rig to a
variable bench supply and then measure power output and supply current
versus supply voltage. Also, note when any irregularities occur
(instability, etc).

Any takers?

Thanks and 73. Lowell
