Content preview: Hi Graham  I will digest your mail and thanks for so much info. I have a beacon that runs on 500kc/s it is not in the Opera band. It is currently at about 10Watts O/P to an inverted "L" up about 35ft x 128ft lng, running QRSS and 12WPM. Clearly seen on the Birmingham Grabber when on. Initially my plan is to run Opera base upon your information. The operating times will be dependent upon Internet usage here and reports. I will also QSY to the Opera frequency in due course. Now you have confirmed it is not a linear mode I will commit my lap top for a period of time to Opera operation and increase power to 40Watts +/-. If I can get a HEX code for a PIC then it will be on Opera more often.  I will let you know the progress.  Once again thanks for the info to date.  73 es GL Pete M0FMT IO91UX [...] 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 [77.238.189.39 listed in list.dnswl.org] 0.0 FREEMAIL_FROM Sender email is commonly abused enduser mail provider (m0fmt[at]yahoo.co.uk) 0.0 HTML_MESSAGE BODY: HTML included in message 0.0 T_DKIM_INVALID DKIM-Signature header exists but is not valid X-Scan-Signature: 8ebe6025b6827c1895957ab180d8d5b9 Subject: Re: LF: 475 kc Exiter Content-Type: multipart/alternative; boundary="1386533404-101519959-1338488029=:92944" X-Spam-Checker-Version: SpamAssassin 2.63 (2004-01-11) on post.thorcom.com X-Spam-Level: X-Spam-Status: No, hits=0.9 required=5.0 tests=HTML_30_40,HTML_FONT_BIG, HTML_MESSAGE,TO_ADDRESS_EQ_REAL autolearn=no version=2.63 X-SA-Exim-Scanned: Yes Sender: owner-rsgb_lf_group@blacksheep.org Precedence: bulk Reply-To: rsgb_lf_group@blacksheep.org X-Listname: rsgb_lf_group X-SA-Exim-Rcpt-To: rs_out_1@blacksheep.org X-SA-Exim-Scanned: No; SAEximRunCond expanded to false x-aol-global-disposition: G X-AOL-SCOLL-SCORE: 1:2:472356256:93952408 X-AOL-SCOLL-URL_COUNT: 1 X-AOL-SCOLL-AUTHENTICATION: mail_rly_antispam_dkim-m286.2 ; domain : yahoo.co.uk DKIM : fail x-aol-sid: 3039ac1d40834fc7b52e0dc3 X-AOL-IP: 195.171.43.25 X-AOL-SPF: domain : blacksheep.org SPF : none --1386533404-101519959-1338488029=:92944 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable =0A=0A=0AHi Graham=0A=C2=A0=0AI will digest your mail and thanks for so muc= h info.=C2=A0I have a beacon that runs on 500kc/s it is not in the Opera ba= nd.

Hi Graham
 
I will dige= st your mail and thanks for so much info. I have a beacon that runs on= 500kc/s it is not in the Opera band. It is currently at about 10Watts O/P = to an inverted "L" up about 35ft x 128ft lng, running QRSS= and 12WPM. Clearly seen on the Birmingham Grabber when on. Initially my pl= an is to run Opera base upon your information. The operating times wil= l be dependent upon Internet usage here and reports. I will also QSY to the Opera frequency in due cou= rse. Now you have confirmed it is not a linear mode I will commit my lap to= p for a period of time to Opera operation and increase power to 40Watts +/-= . If I can get a HEX code for a PIC then it will be on Opera more often.
 
I will let you know the progress.

Once again thanks for the info to date.

Hi Graham
=0A
Is there any proper docum= entation for this Opera stuff? Like =0Adescription of the method of Keying = and how the logging system works. How do you =0Aget qso data off the application other than screen dump= s which seems a bit =0Acrude. There are software buttons but they don't all= work as =0Aadvertised.
=0A
 
=0ACan you tell me where the full documentation is kept?
= =0A
Can you tell me the Keying principle? I have not put the PC S= C output =0Aon the scope but there must be an easier way to get at the info= . Is it FSK or =0APhase shif= t or some clever On/Off keying or Magic?
=0A
Is there= a web data base or is the screen info just a one =0Ashot?
=0A<= div>Do I need an Internet connection during Beacon or QSO ing? With my =0Aissues concerning Good Old BT and their 19th century technology, rusty =0Acopper and wet string, in = the far flung out posts of North He= rtfordshire that =0Acan't be done, so does that preclude full use of= this system.
=0A
Or is it all a secret and one has t= o dig into the application? Info =0Ain README is sparse.
=0A
Has there been any p= rojects to put this application of PIC processor =0Afor say TX Beacon mode?= Or RX for that matter?
=0A
 = ;
=0A
There are more questions but any help would be of inte= rest. Now that =0AI have managed to probably defeat BTs best efforts to keep me off 500kc/s I =0Aw= ould like to explore this mode a bit more. Thanks.

TX500 is not supporting WSPR or Opera

Opera is =0Aa = single frequency  on/off    CW key replacement  mode , = if =0Ait  can
send  CW or  QRSS  , then  it ca= n  =0Asend  Opera  via the  com-port keying
