The FT-891 is a great alternative as you can just leave it at 5 w and if you need more just dial it in. You dont need 100w or the 25A draw when you can make contacts at 20watts with a good antenna like a linked dipole

Certainly... But the 891 burns 5A at 5W output. My MTR burns 0.7A at the same power output... Not to mention the 35mA on receive...

13.8VDC at 5 Amps = 69 Watts to produce a 5 Watt signal.  Receive current is also too large for real field work., unless you're vehicle mobile or drag it to the nearby operating area , then back to the car. It's a matter of what you prefer, but I prefer portable.

My opinion as well Ray.

Julian did make it work with new battery technology and a large solar panel, but I also prefer something that fits in a small bag or a large pocket for that matter... One thing that might work is something like the new QRPVer digital QRP transceiver:

But you still need a tablet... It is a small solution for someone who does not want to learn Morse code.
