Thanks, Rich! I had not thought of that. I'll give it atry. Appreciatively, 73 Bob K5LLF ----- Original Message ----- From: Richard Ferch [via Elecraft] To: Bob Sent: Saturday, August 14, 2010 4:47 PM Subject: Re: K3 and PTCIIUSB
Bob, When you used USB you said you widened the filter. I'm guessing that was the key to your success. Try widening the filter in DATA A mode. The filter in DATA A is centered on 1500 Hz, and the default width is 400 Hz. I don't know where the PTC II's Pactor tones are centered, but I am guessing they are outside the DSP filter bandpass at the K3's normal narrow filter setting. Once you have determined where the PTC II's tones are, you can use the K3's SHIFT control to re-center the filter on them and then use WIDTH to widen or narrow the bandwidth as appropriate. The same is probably true for your other digital modes. A 400 Hz filter centered on 1500 Hz will not work with MT63, for example, but simply readjusting the filter settings will allow you to use DATA A for MT63. 73, Rich VE3KI K5LLF wrote: >The beta version of Airmail 3.4.034 has a K3 option and its HF > Terminal module puts the K3 in DATA A mode.

No joy with DATA A. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ------------------------------------------------------------------------------ View message @ http://elecraft.365791.n2.nabble.com/K3-and-PTCIIUSB-tp5424038p5424121.html To unsubscribe from K3 and PTCIIUSB, click here. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-and-PTCIIUSB-tp5424038p5424314.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
