Why would you think that?

 From the FCC R&O 17-33 
(https://apps.fcc.gov/edocs_public/attachmatch/FCC-17-33A1.pdf):

23. Radiated and Transmitter Power. As discussed in the WRC-12 NPRM, we 
adopt maximum EIRP limits and transmitter power limits for the new 
amateur service bands. Amateur stations may operate in the 135.7-137.8 
kHz band with a maximum radiated power of one watt EIRP. Several amateur 
service commenters recommend that we specify a maximum transmitter power 
developed specifically for these bands, while others recommend that a 
maximum transmitter power not be specified, or that we apply only the 
general Part 97 transmitter power limit to both bands. We find that 
amateur stations operating in the 135.7-137.8 kHz band should be subject 
only to the general Part 97 limit of 1.5 kW peak envelope power (PEP). 
We find it unnecessary to limit the transmitter power
beyond what it is already provided for in our rules, because antennas 
used in this frequency band are highly inefficient in converting the RF 
power delivered to the antenna terminals.

24. We also adopt the power limits proposed in the WRC-12 NPRM for 
amateur stations operating in the 472-479 kHz band. For such stations, 
the maximum radiated power will be five watts EIRP, except for stations 
located in the portion of Alaska that is within 800 kilometers of the 
Russian Federation, where the EIRP will be limited to one watt. We also 
limit the transmitter power for amateur radio operations in the 472-479 
kHz band to 500 watts PEP; provided, however, that the resulting 
radiated power does not exceed five watts EIRP.  In other words, it may 
be necessary to reduce transmitter power below 500 watts PEP to avoid 
exceeding the five watts EIRP limit.

BTW, 1730 M is NOT 137 kHz. 1730 M is under Part 15 rules and has 
nothing at all to do with either 2200 M or 630 M Part 5 or Amateur rules.
