| The 705 and [[706]] are essentially the same. The 706 does not have the compartment in the bottom to hold a 9V battery to supply voltage for the electret mic and circuitry. The [[706]] only works with rigs that supply the necessary voltage through the mic connector whereas the 705 can operate from rig voltage or battery. Also the 705 has a switch on the bottom to tell the controls on the mike base if you operate VOX or PTT. The 705 has a bit more versatility for use with older transceivers not having voltage present at the mic connector for the electret mic. | The 705 and [[706]] are essentially the same.

| + | ===== Corsair Modification ===== | ||
| + | The documentation that accompanied the 705 microphone included information on modifying a Corsair I or early Corsair II (s/n before 1970) to power the 705 microphone. The modification involves shunting an existing 10K ohm resistor on the IF/AF board with a 470 ohm 1/2w resistor. | ||
