[digitalradio] ROS MF-7 IS OUT THERE ! (And less than 100 Hz wide)
After a series of successful test transmissions, the latest version of ROS-3-6-1 (at the moment) now has the MF mode included , this allows live key board qso's at a data rate close to 500/8 and also has a baud-1 mode with enhanced s/n performance , transmission via non-linear systems is possible , though the logic drive of calss e/d will still present problems. To comply with the EU 100 Hz data bandwidth of the 500Khz permits the mode is coded to occupy less than 100 Hz , the first custom mode to be produced to enable data communications with in the EU on MF The first on air qso over 200 miles is listed http://lfistes.erst.azerttyu.net/viewtopic.php?f=17t=1982sid=5f68ac5172a5c1206214df5b03c2bc50 Its quite possible that the 100 Hz mode will function well over HF over the polar paths where psk tends to fail ?

good news, nice to see this mode make good progress.

[digitalradio] Re: CALL ID via PSKReporter
Andy If you want to have a special way of showing these records in PSKReporter, then please let me know and maybe I can implement it.

It is not as instant as I would like, PSK Reporter updates every 2-3 minutes, I think. Not bad though.

Re: [digitalradio] Re: CALL ID via PSKReporter
Thanks Phil. I think the one issue is something you don't have control over, that is the Call ID that is decoded actually being sent to PSK Reporter. In Multipsk the decoded call ID is stored (by user option) in a txt file. As far as i can tell, this is not automatically sent to PSK Reporter unless the user has Multipsk configured to send to PSK Reporter. I am not sure how many people choose to send to PSK Reporter versus simply leave the option unchecked. What I was playing around with is a way to automatically upload the decoded call ID to a web page regardless of the user option to send to PSk Reporter. Multipsk , as you are already aware, produces a line like... 15:21:19 CQ K1DOW-EL97BE-4 3009 Hz in the Call ID area.A none map version of PSk Reporter where it list multiple decodes like 15:21:19 CQ K1DOW-EL97BE-4 3009 Hz 14:56:39 CQ K3UKFN02HK -3 3009 Hz 14:56:05 CQ K1DOW-EL97BE + 2 3154 Hz 13:38:25 KA1GMN/5 + 4 2194 Hz might be useful but perhaps that is already possible with the logbook view in PSK Reporter.

[digitalradio] Re: ALE 400 coming out of the woodwork
That's good to hear. I have had only a couple of ALE-400 QSOs but both were very pleasant. I would be participating in this weekend's activity except I'm away from home. Do you have any feel for how robust ALE-400 is versus some of the other modes? Of course it's error-free because of the ARQ, but does it need a better signal than, say, Olivia to get through? Jim W6JVE
Re: [digitalradio] Re: ALE 400 coming out of the woodwork
my subjective view , Jim, is that it is almost as robust as Olivia under common weak signal conditions. Andy K3UK On Sat, May 15, 2010 at 12:36 PM, jhhay...@earthlink.net wrote: That's good to hear.

Re: [digitalradio] Re: ALE 400 coming out of the woodwork
Hello Jim, but does it need a better signal than, say, Olivia to get through? The minimum S/N is around -12 dB. It is comparable to the minimum S/N for Olivia 32-1000 or Olivia 8-500. However, below -11 dB, repetitions begin. 73 Patrick - Original Message - From: jhhay...@earthlink.net To: digitalradio@yahoogroups.com Sent: Saturday, May 15, 2010 6:36 PM Subject: [digitalradio] Re: ALE 400 coming out of the woodwork That's good to hear.

Received lots of positive feedback about the article. Great to see all the activity on the band. Patrick, This article could be a real boost to you very creative application. I certainly hope Patrick receives some well deserved recognition for his work. Tony -K2MO
