In all the? writing? on ubitx website, I read that the power supply should supply? up to 3 amps, but elsewhere, on same site, I read that? the 12 volt regulated line should be fused, at? 2 to 2.5 amps.??? Do you get? same range, of 1.4 to 1.8 amps, when transmitting, as I suspect transmit mode will probably draw more current than in receive mode???? I tend to think that 2 amp fast blow fuse; perhaps 2.5 A at the most, is appropriate.
