I checked a few times during the day on Monday and did not hear it. At 0200z I checked again and it was there and very loud...40dB over s9. Definitely louder on my NE antenna, but only by 10 dB or so. Maybe it is close enough that it is arriving at a high angle. But 30 seconds after I tuned in, it stopped! The signal characteristics are almost identical to CODAR sea-surface radar. There are three of those installations in Maine and VE1 that are easy to hear on 4.8 MHz. Maybe they are trying smoethign new there. Or maybe is it in TF or even shipboard somewhere off Newfoundland...the CODAR system uses fairly small antennas and low power, so it is possible. I placed a phone call over the weekend to the Operations Manager for one of the projects using those sites and left a message asking if they had something running at 1.9 MHz, but no answer yet. 73, Doug K1DG Long Island, ME FN43 _________________ Topband Reflector Archives - http://www.contesting.com/_topband
