A SECOND SET OF TESTS WERE RUN IN THE EVENING ON THE 75 METER PHONE BAND, WITH THE EXPECTATION THAT THE NOISE SPECTRUM OR OTHER CHARACTERISTICS WOULD BE DIFFERENT. THE NOISE LEVEL WAS DIFFERENT, RUNNING S 6 TO S 7. THERE WAS GENERALLY NO DIFFERENCE IN PERFORMANCE. A FEW STATIONS WERE BARELY DISCERNABLE AT THIS HIGHER NOISE LEVEL. SOME COULD BE PULLED OUT BY CHANGING THE DSP FILTER LEVEL. OTHER BARELY DISCERNABLE SIGNALS POPPED OUT OF THE NOISE, BUT THEY WERE UNINTELLIGIBLE. AT THIS LOCATION, MANY STATIONS ON THE 75 METER PHONE BAND TEND TO HAVE SIGNAL STRENGTHS OF S 9 PLUS 30 DB SOME OF THE NOISE AROUND THE WEAK STATIONS MAY BE SPLATTER OF SOME SORT FROM ONE OF THESE STRONG STATIONS. FINALLY, A NUMBER OF LISTENING TESTS WERE RUN ON 20 METERS DURING THE DAY. RESULTS WERE THE SAME AS ON 40 METERS. NO S 9 PLUS 30 DB CLOSE STATIONS WERE ENCOUNTERED ON EITHER 40 OR 20 METERS. IN SUMMARY THE MOST INTERESTING CHARACTERISTIC NOTED IN THESE TESTS WAS THAT ON A WEEKEND AFTERNOON, WHEN THE POTA CONTEST WAS VERY ACTIVE, OPERATION WAS PRIMARILY HANDS OFF. THE DSP FILTER LEVEL WAS SET TO 2 AND LEFT THERE, EXCEPT FOR A = END OF 30 WPM TEXT = QST DE W1AW <
