Basic U. S. regulations below; International regulations vary. During the
last sunspot peak, Russian cab drivers were heard regularly above 29.1
MHz on AM.
Novice CW
28.000-28.300 MHz is a very active part of 10 meters for CW operation. 
Novice/Technician phone
28.300-28.500 MHz is probably the most active part of the 10-meter band.
Operation in this segment is almost exclusively SSB worldwide. 

AM sub-band
>From 29.000 to 29.200 MHz. Formerly practice was to use the band in 10
kHz steps: e.g. 29.010, 29.020, 29.030,... etc. This has not been the
case since the 1970s, which saw an influx of surplus 23-channel CB
equipment modified for use on the 10-meter amateur band. The surplus
equipment would land in 10 kHz steps on the 5 kHz step such as: 29.015,
29.025, 29.035, etc. Users of the surplus equipment also inherited those
radios' odd channel spacing, which on CB skipped channels that were not
used there, because they were set aside for remote control operations. 


Amateur Extras, Advanced, and Generals can operate phone from 28.3 MHz to
29.7 MHz with full power. Only Novice and Technicians have the 200 watt
and SSB limit from 28.3 MHz to 28.5 MHz.

I dont think AM is allowed in the Novice subband of 10m.
Didn't Ashtabula Bill get in trouble for that? 
Plus, a 200w PEP limit of power...

Courier 23 is a 23 channel AM transceiver. The majority of all 10 meter
AM contacts happen within the AM band plan designation of 29.0 to 29.2
MHz. You might find some AM signals coming out of Japan around 28.310
MHz.
Not to say you can't work SSB stations somewhere within the 10 meter band
but you might have add a BFO to the Courier 23 in order to understand
what they are saying.
You should have mentioned, if you convert it to 10 meters, what
frequencies do you wind up on. 10 meters covers a big range of
frequencies.
