[digitalradio] Test version of Multipsk about ARQ FAE in ALE400
Hello to all testers, Following the previous tests (which target continues to be to test the reconnection in case of QRM, QSB...), I have issued a new test version about ARQ FAE in ALE400, Modifications: * I've reduced the detected bandwith to +/-120 Hz to avoid any off band RS ID, * the asymetry Slave/master is increased, * RS ID is sent at retry 3, 5, 7... Here is the Multipsk test version: http://f6cte.free.fr/MULTIPSK_TEST_15_09_2009.ZIP Paste this adress in your Internet Explorer or equivalent. Download the file. Create a tempory folder (C:\TEST, for example), unzip the file in it and start C:\TEST\Multipsk.exe (the auxiliary files will be created automatically). For ALE and ALE400, see: http://f6cte.free.fr/ALE_and_ALE400_easy_with_Multipsk.doc http://f6cte.free.fr/The_ARQ_FAE_beacon_easy_with_Multipsk.doc Experimentation of the ARQ FAE / ALE400 For experimention, once connected, it would be useful to send something, to slighltly change the reception frequency (to create a problem) and to see how works the reconnection. It would be also interesting to stop the TX power for about 10 seconds to see how it reconnects afterwards. Normally, it must reconnect for a S/N = -10 dB (the S/N measure is near the top bar of the Aux. functions window). I will call, to-night, on 3585 KHz USB HF 1000 Hz AF +/- QRM, in ARQ FAE / ALE400 for QSO since 20h00 UTC until 20h30 UTC. PSE push on the RX RS ID button. Hint: on the waterfall, the beginning of ALE400 transmission seems to be 2 paws with 3 nails on each paw. If the AF frequency is well adjusted, the 2 blue vertical dashes must normally coincide with the 2 central nails. 73 Patrick

Hello to all, For the ones interessed by RS ID (and Video ID), I have put an article on Wikipedia about this subject. http://en.wikipedia.org/wiki/Reed_Solomon_Identifier_(RSID) This article is going to be deleted from Wikipedia the 19/09/2009, so...

Re: [digitalradio] Re: Test version of Multipsk about ARQ FAE in ALE400
Hello Mike, With Windows it is not possible to conceive synchronous system as Pactor, because you can't control each sound sample (you can't decide to send a sample at a given time) as it was possible under DOS. So only asynchronous system as Packet, Pax and ARQ FAE are possible. It means that there are no precise moments for which you can receive and transmit. It must be accepted to have provisional loss of connection due to QSB or QRM and necessarily collisions. If Master and Slave are symetrical (same waiting times), they are going to transmit and receive at the same moments and consequently never reconnect. So in ALE 400, the Master waits 2.5 sec and the Slave 6 sec, the goal being that at some moment the Master hears the Slave or reversely to reconnect. However, below -10 dB (weak signal) it is very difficult to reconnect. We tested this to night with Steinar (LA5VNA) by decreasing TX power down 5 watts (below it is difficult to know the power). 73 Patrick - Original Message - From: mikenetbot mikenet...@comcast.net To: digitalradio@yahoogroups.com Sent: Tuesday, September 15, 2009 10:05 PM Subject: [digitalradio] Re: Test version of Multipsk about ARQ FAE in ALE400 Wow Patrick, you're really on top of things tweaking this mode.

2.5 sec and the Slave 6 sec, the goal being that at some moment the
Master
hears the Slave or reversely to reconnect.
I didn't realize this with ARQ FAE Patrick. If you use a SELCAL does the
answering station automatically change mode to slave and the
initiating station to master (if it was not already) ?
