Re: LF: XPQ 137.552 carrier OP32

Jay, Laurence,

 

several opds detections of WD2XNS last night. Zoomed spectrogram at

df6nm.bplaced.net/opera/opds32_131125_0658.png

 

Unforetunately not a trace yet from WE2XPQ on 137552, only the predicted neighbouring Loran lines:

WD2XNS running OPDS32 on 137553 for a while tonight.

Laurence,

 

just checked for potential Loran lines listed in

http://dl.dropboxusercontent.com/u/26404526/Loran_lines_in_LF_slots.txt

The closest ones in Europe will be 137551.6736 Hz (GRI 7499, Sylt) and 137551.7783 Hz (GRI 7001, Bo), and in Japan 137552.8701 Hz (GRI 9930). In the eastern US, 137551.3906 Hz (GRI 8270) could be a near one in case the Wildwood NJ experimental Loran station came on air again. 

 

Anyway considering the Op-32 modulation bandwidth of about 0.125 Hz, all of these lines would be spaced far enough from your intended QRG.

 

Best 73,

Markus

I should have asked - but Ive put myself close to the centre of the windowed Op32 passband - not sure if anyone else has plonked themselves closeby? - Im about 3Hz higher than BDQ decoded freq - tell me to move if Im QRMing... :-) or suggest a freq.


No arcing as of yet - ambient temp inside the tuner helping but the spiders are probably not happy now.  Nice to be back on Tx -  Im backed off a fair way on power as  Im pushing a smaller mica past its current derating at 137kHz, and that should be replaced next week hopefully - Ill go out with the active laser thermo-meter in a while and look for component heating - always a good idea
