[TenTec] Choosing a QRP HF rig with 3A max supply current

[designer]

The SGC-2020ADSP runs 3.5 amps @20Watts so you might be able to dial 
it back. It is not the best in anything - though the DSP sure quiet's 
the noise level down - but seems to be good enough for a portable, 
take anywhere and run off a battery, rig.

It doesn't compare to the Argo V - but I wouldn't take the Argo V on 
a camping trip.
