I was playing with a friend's new 756 PRO III (he won it at Dayton this year!!) and it seemed very nice down below the BCB but he notices a rise of internal noise from around 250KHz down to 50KHz. The noise is also visible on the scope as a rise in the rx ambient noise floor. I take it that you don't have this problem with yours?</FONT></P></FONT></BLOCKQUOTE></DIV> <DIV></DIV> <DIV>================== =========================</DIV> <DIV> </DIV> <DIV>My original 756 radiates noise from the LCD display. I have to keep open feeders and any loop antenna several feet from the radio.</DIV> <DIV> </DIV> <DIV>The original 756 has poor performance below 500kHz primarily due to transformer design, but also because of the attenuator that is permanently switched in for MF / LF reception. Even so, with a pre-amp its a good LF receiver due to the flexible DSP and other filtering. </DIV> <DIV> </DIV> <DIV>73</DIV> <DIV> </DIV> <DIV>David G0MRF</DIV></FONT></BODY></HTML>
