No so, only in the UK generally, and 10w erp has been authorised in the past,  other countries 20 plus watts erp.
If you have a vy small antenna you would need around 5Kw to get 1w erp and would need about 10 T-200 toroids stacked times 2 for your filter.
The trend in the past on 137 has been to work long haul with the odd local QSO.
