[Lowfer] MP in EN90xn

[Michael Sapp]

Mitch:  MP very audible here. I reworked my EWE antenna and transmission line choke ground rods and chokes while you were off the air, so there are performance changes on this receiving end....

My 10MHz non-GPS disciplined reference in the Spectrcom WWVB receiver was about 1Hz off WWV on my 10MHz WWV reception.  LF converter IF at 3MHz so the error potential there is
.3Hz---but the Spectracom receiver has a divide by 100 output at 100kHz and I used that to cal.....(.003 theoretical limit).  ARGO did not want to move from 499.99 to 500.00 Hz (my CW bandpass) during calibration without forcing a larger number than what seemed appropriate. So I left the cal at 499.99 Hz and set the offset for 137780.  With a few milliHz per hour drift I may be .03 to .05 off....then again that may be wishful thinking on my part....

Nice signal here with the AGC off in ARGO and the FT-817 IF radio....


I switched the LF receiver to EAR and will let it run over lunch and submit results in an hour or two....
