Re: LF: 29.499 tonight OP2H/DS...

Days are getting warmer, nights are shorter, and QRN is increasing...

 

This morning was noisier than last night, and the Op-2H carrier was not very conspicuous here in the 106 uHz spectrogram. Anyhow a "deep deep search" with reduced carrier detection threshold produced a single hit with decent correlation:

2014-04-02 05:54:29 WH1XBA  6448km  29499.000Hz   0mHz -60.5dBOp 100% 14.6dB

 

I have annotated those reduced-threshold detections by an asterisk and added them to the table at the bottom of the opds page

Bob, in spite of your carrier standing out well above the noise this morning, overnight opds-2H produced no hits above the correlation threshold which is currently set to 14 dB. Rerunning the data with lower threshold showed one close detection:

2014-04-01 02:59:24 WH1XBA  6448km  29499.000Hz   1mHz -56.1dBOp 100% 13.8dB

 

and another one which seemed to have good SNR and plausible timing but very low correlation:

2014-04-01 05:10:42 WH1XBA  6448km  29499.000Hz   1mHz -51.9dBOp  76% 11.8dB

 

Unfortunately no trace from Dex on 29501 became visible.
