Thanks Laurie. 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
My original 756 radiates noise from the LCD display. I have to keep open
feeders and any loop antenna several feet from the radio.
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.
