Christy, 70cm is harder to hit. If you're using an antenna indoors you may well
have problems hitting the repeater. Run the rig on 35w if the antenna will
handle the load. Also, if you're using a magmount try sitting it in a frying
pan (cast iron works well for this) to get some ground plain effect.
Rigs like the Kenwood ts570 have a built-in antenna tuner.
Since you have a computer you can get a serial cable to connect to that 707
and get output if information from the radio that isn't spoken normally.
