Saku,
I thought your measurement of 5 carriers should be around -8dB –
10log (5)=-15dB but your measurement was much worse.

1.Here in KP01 / OCF dipole: W7/KH7Z , if 1 carrier, is loud abt -8dB,
but
2.5 carriers -19 .. -22dB and mostly useless (gets rolled by qsb/qrm).
Hi Take-san,
the output when NSlots >1 is not a simple distribution of the Tx power
between tones, the reason for this is that multiple tones will mix and
some filtering is necessary to minimize undesirable side-bands. The
result for NSlots=5 is a power reduction per signal of ~14dB with
respect to an NSlot=1 transmission using the same radio settings.
