Rondo, I checked the FCC rules again to verify the rules for 10m. It is correct that you may transmit CW and single sideband (SSB) voice on the 28.300-28.500mhz portion of 10 meters IF AND ONLY IF you have passed the Technician class written exam AND the 5 wpm Morse code test. That is, you and the wife MUST both hold what is generaly called "Tech plus" licenses. To get frequency privileges in phone mode (voice) beyond that (e.g., outside the 28mhz slice plus 20m, 40m, etc.) you must BOTH hold General class licenses. This requires passing a 35 question written exam in addition to the 5 wpm code test. Hope this helps.
