Joe, yes 137555 Hz seems perfectly ok to me. According to my logs, PA0OCD and others have been operating nearby a couple of times about two months ago. But all these stations have variable frequency
May be , I don't know who else runs fixed , I think Spiros runs 137.540 , RN7T has a multi beacon , but the b/w is so small , there is little chance of problems . If you add the qrg to the web-beacon
Hi Joe , Well its mid summer again ! Best I advice I can give is head for the middle of the two bands , op32 137.55 or op08 137.65 , this allows for any off sets in the the Rx side etc, 5 or 10 Hz of
Hello Joe, No problem. As usual, your QRSS signal gave here a strong trace this morning with peak around 0230 TU. Stable signal better than .005 Hz / 2 hours, no chirp. I was using my long Inv L ante
Hi Andy and thanks for the report and gratifying info on the stability. It seems to be working quite well and the frequency reports are very good, given that the DDS resolution is about 15 mHz. To Ja
Hi Graham, yes it's true that the opds correlation detector does not attempt to directly decode any of the Opera 28-bit message contents (ie. the callsign). But you do get more than a single yes-or-n
Graham, Thank-you for all the info. It will come in handy when I start using Op again. Unfortunately, there were some stability issues last night which should be resolved soon. When that's done and a
Ok Marcus Thanks for the info on the no-go zones , the decoder is quite robust in terms of carrier in the pass band , i think 64 decodes are possible , may be less on the narrow windows , but still o
Joe, you wrote 07.06.2013, 23:04 MSK(GMT+4h): Marcus DF6NM can watch Op32 anywhere (??) Today I'll only RX Op32 (137600...137700), Op8 (137500...137600) and WSPR-15 (137600...137625) - no multimodes
