It seems that 144.165MHz is being adopted as the 2m JT65B frequency in Europe. This morning, starting shortly, I shall be beaconing sending on that frequency (USB dial). Any reports would be appreciated. Best to upload your spots to PSK Reporter Maps. My actual transmission will, of course, be slightly HF of the dial setting.
UPDATE 1040z: Within minutes of starting I copied DL1BEC (487km) on 2m JT65B in Lower Saxony, Germany. This was totally unexpected! No spots of my 2W QRP as yet.
UPDATE 1904z: Several spots from G6AVK (77km) - thank you.
