A couple of you have asked about my mod to the MN2700 to adapt positions 3 and 4 of the MN2700 antenna switch for coax feedlines. This mod is for those of us that don't have the B1000 balun and don't run balanced feedlines or long wire antennas.
Open up the MN2700 and unsolder the three leads at the Fiberglas terminal board that connects to the B1000. Remove the Fiberglas board and save it so you can restore your MN2700 someday in the future.
Fabricate a replacement board of the same size out of scrap aluminum. Mount two SO 259 connectors to the board. Mount the board into the MN2700 in place of the Fiberglas board (the SO 259 connectors should just clear the rear panel cutout--thank you Drake). Solder the two leads from the antenna switch to the SO259 (leave the grounded lead floating). That's it.
Here's a picture of the additional SO259 connectors:
