I think I would rather have an Elecraft OR a 7300 for portable qrp or at home respectively.
I like the idea of the 705 but high current drain and no tuna is a big downside.
vhf/uhf is nice, high performance is nice, but Elecraft wins on the portable battery operation segment, low power draw, antenna tuners that can actually tune an antenna, small and light weight.
I wish Elecraft could come up with something like the MChf radios, all mode, built in battery and band scope, great fidelity, filters, color display, just add their great antenna tuner to a package like that.
At any price, I think I would have to go with a KX2 or KX3 if we are talking 10 watt radios for use in the field.
I can't see the 705 being as good for that.
