Hello Thomas, > When you have had it occur 40-50 times(with 20 over sig.) ..then tell me > its not major. As this frequency (40-50 times) is not normal, I think there is another problem.
Hypothesis: I suppose that you want to do a QSO, have clicked on "ARQ FAE" and "CQ" and a Ham has done the connection with your station. Note: if you are the "Master" (the one who initiates the QSO), it is better to check "Master" in the "Mode" box, this to come back to your initial AF frequency and to avoid a drift in frequency. I list below the possible problems: * sound card sampling frequency not adjusted...solution: <Adjustments> menu, click on <Determination...>, * AF level too low (<10 %) as displayed in a caption to the left of the Mode panel: you must target about 30 to 50 % (not critical) using the mixer. Possibly , you can sample in 16 bits (you will win about 2 or 3 bits in fact due to noise): <Adjustments> menu, click on <AF level...>. However, the most robust, CPU economic and simple is to work on 8 bits. * your computer must be fast (>1000 MHz) not to introduce big CPU delays, * to switch XCVR, prefer direct control or CAT system. With VOX, the introduced delay (VOX+XCVR) must be checked (above 130 ms there is a problem for ALE400), * of course, the AF level to the XCVR must be adjusted (not to overload the XCVR or not to be close to the noise), but it is not different from any other mode. * Possibly, unclick the "AFC" (in case of big QRM (RTTY for example) on your frequency). For procedures, refer to: http://f6cte.free.fr/ALE_and_ALE400_easy_with_Multipsk.doc http://f6cte.free.fr/The_ARQ_FAE_beacon_easy_with_Multipsk.doc I hope this helps a bit. Note: about this problem, it would be better to continue on the Multipsk Yahoo group. 73 Patrick ----- Original Message ----- From: "Thomas Carswell Jr." <kt4w...@gmail.com> To: <digitalradio@yahoogroups.com> Sent: Sunday, August 30, 2009 6:36 PM Subject: Re: [digitalradio] ALE400 > Trust me pal... been using ALE400 from the start...the outa-sync issue > is not just a > one time thing... and not just on QRP. > Im a big fan of ALE400 and MultiPSK(reg)...BUT,,,, It IS a major issue. > When you have had it occur 40-50 times(with 20 over sig.) > ..then tell me its not major. > I have had 100+ QSO's in this mode....with 10-12 diff. ops. > BTW..the new "PSK-Packet" has the same problem. > KT4WO > > > On 8/30/09, John Bradley <jbrad...@sasktel.net> wrote: >> >> >> "> I have brought this up to Patrick a few times....I asked for a >>> "slottime" or some random timer... >>> I think this would solve the problem.
