There was a lot of stuff that was dual-band 6 & 2 meters in the '60s and 
'70s.    The Collins 62S-1 VHF transverter with a 4CX250 final, the Heathkit 
Seneca 6 & 2 meter AM/CW transmitter, the Johnson VHF Thunderbolt 1KW 
amplifier, All these actually bandswitched numerous tuned circuits between the 
two bands.   Hy-Gain made several 6n2 dual-band antennas.   Actually 6 & 2 
dual-band antennas are easy to do since there is a nearly  third-harmonic 
relationship between the two bands.

I am presently running a currently-available Comet SB-14   6M-2M-450   mobile 
whip. At home I have the fiberglass-sleeved base station version of the 
slightly taller version of the same triband mobile antenna, the SB-15.

Any of the current "DC-to-light" all modes such as the Icom 706, the Yaesu 
FT-857, Kenwood TS-2000, etc can put out 100W on 6 meters.  And all of these 
radios have the mini-DIN data ports that give you direct access to the RX 
discriminator and TX modulator so 9600 is easy to do.
