Luca, Check to be certain your sidetone pitch is set to the same frequency as you set the center of the CW filters. After checking that, go back to the Filter alignment and check the BFO frequencies while on a band no higher than 17 meters - The BFO frequency for CW should be lower than that for CWrev. The symptom you describe often occurs when you have the filter on the wrong sideband.
Bottom line - all CW BFO frequencies should be around 4913.xx kHz and the CW rev BFO frequencies should all be in the vicinity of 4914.xx if your crystal set is typical - Since CW FL1 is usually a wide filter, the BFO frequency for CW Rev FL1 may be higher than I mentioned by a kHz or so. luca amendola wrote: > hi friends > my last message was blank because I sent it via web! > as tom and don suggested I re-calibrated all filters with the cal fil option > and the receiver shift now is fixed. > unfortunally I found a minor problem in tx mode: my tx frequency is around > 0.6 khz up. > so I'm serching help again. hihi > any suggest? > thanks > luca > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:[email protected] > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > ------------------------------------------------------------------------ > > > No virus found in this incoming message. > Checked by AVG - www.avg.com > Version: 8.5.392 / Virus Database: 270.13.58/2306 - Release Date: 08/16/09 > 06:09:00 > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
