Content preview: Ok Stefan Well , OP8 is only the entry mode for 136 :) with every X2 of the time , add another -3 dB , at the moment , OP8 and OP32 seem to give good results , hopefully other speeds can be tested , OP32 lowers the s/n by -6 dB [...] Content analysis details: (0.0 points, 5.0 required) pts rule name description ---- ---------------------- -------------------------------------------------- -0.0 RCVD_IN_DNSWL_NONE RBL: Sender listed at http://www.dnswl.org/, no trust [80.12.242.68 listed in list.dnswl.org] X-Scan-Signature: 138e3b341e0543401afa7e97ee054540 Subject: Re: LF: 136 More OP RX stations needed !

But the longer on/off times also means that it shows on S/L , but there may be some problems with sound card using OP and S/L on the same P/C .. its possible that Op is not able to decode at the extreme limits , José's DSP engine is pushing the limits .. Decodes , well at the moment I have the Ae set for 500K , so not ideal for 136 , but I have two decodes , via the 500 tuner :) 22:24 136 DK7FC Op8 -32 dB 21:51 136 DK7FC Op8 -33 dB This is outstanding ! at 20 dB in Reykjavik ~~ 13 dB above the minimum decode level , you could reduce power by a factor of X 20 ! 22:24 136 DK7FC de TF3HZ Op8 1515 mi -20 dB in Reykjavik Well , as I have posted in the past the Op system has made operating on MF/LF quite simple , PSK-Map showing 24 monitors at the moment , lets hope East coast USA joins later in the night GL -73-G.. -------------------------------------------------- From: "Stefan Schäfer" Sent: Thursday, July 19, 2012 10:47 PM To: Subject: Re: LF: 136 More OP RX stations needed ! > Hi Graham, Op fans, > > That seems to work very well, i haven't expected that.
