[digitalradio] New ARQ FAE mode on Multipsk
I am pleased that ARQ FAE, a modest speed 8 bit ASCII data ARQ sound card mode, is available for the first time on MS OS. This is a major breakthough. The speed is slower than P2 and we must not forget that the bandwidth is extremely wide at 4 times P2. But it is moving us in the right direction for higher speed ARQ sound card modes that work much deeper into the noise than the previous attempt with SCAMP. ARQ FAE is in the 150 + wpm speed, Pactor 2 can got up to maybe 500 wpm, maybe more with compression? SCAMP was close to 1000 wpm and had a slightly wider footprint than ARQ FAE, but that was under really good conditions. In comparison, P3 has a similar footprint but can operate with a raw speed of over 2000 wpm and with compression can get way over 3000 wpm in the best conditions. So we have a long way to go, but we are making progress. 73, Rick, KV9U John Bradley wrote: Have a look at Patrick's 141A ARQ FAE mode on Multipsk.

Re: [digitalradio] Re: Call for comments on open protocols
I think because it's easier to regulate the provider rather then the user. If someone builds and 3000 watt amp themselves and it has horrible emissions that person has to be tracked and proven to be out of spec, not an easy task even when they are obviously guilty, however if Yaesu makes a digital protocol that uses twice the amount of legal bandwidth, there not very hard to find and little needs to be proven because they will have documented their product. Also AM has been grandfathered in. - Original Message - From: kd4e To: Walt DuBose Cc: [EMAIL PROTECTED] ; digitalradio@yahoogroups.com Sent: Sunday, February 25, 2007 11:24 AM Subject: [digitalradio] Re: Call for comments on open protocols Walt DuBose wrote: Currently we CAN operate modes wider that 3 KHz however only to transmit images. Did you mean for this to apply only to digital modes? I have always understood that the limit factor to SSTV quality was tight restrictions re. speed/bandwidth. In response to challenges to WiFi AM and SSB the FCC response was that they are essentially unlimited as to legal bandwidth so long as they do not QRM others. Has that ruling been updated since (I believe it was two or three years ago)? Ragchewers running HiFi AM SSB chew up huge chunks of shared Ham spectrum all the time and I am unaware of any FCC action to limit their bandwidth. Beyond that are the Hams running unfiltered broadband CB and homebrew amps, overdriven and some well over legal limits -- and little action by the FCC to stop that either -- they are usually obvious on the air. This on top of the neo-commercial abuse of Ham bands by automated Pactor III users. Why the nitpicking of digital and SSTV bandwidths when there is so much abuse elsewhere? Just wondering ... -- Thanks! 73, doc, KD4E ~~ Projects: http://ham-macguyver.bibleseven.com Personal: http://bibleseven.com ~~

Re: [digitalradio] New ARQ FAE mode on Multipsk
Hello to all, How fast can 141A ARQ FAE transfer data? To complete Rick about the transfer data. ARQ FAE sends mainly 8 bits characters (8 bits to be able to manage all characters writings, as Greek). For bit transfert, you must use the TCP/IP link which is also available for FAE. This means that after the link done, you can transmit bits (put in form of characters) to Multipsk through the TCP/IP TX link. Through Multipsk and the TCP/IP RX link the other Ham will take the characters and transform back to bits. Note: ALE in general would need only 1000 Hz (to have orthogonal carriers) but 2000 Hz is better to fight against QRM QSB ... 73 Patrci . - Original Message - From: KV9U To: digitalradio@yahoogroups.com Sent: Monday, February 26, 2007 5:15 PM Subject: [digitalradio] New ARQ FAE mode on Multipsk I am pleased that ARQ FAE, a modest speed 8 bit ASCII data ARQ sound card mode, is available for the first time on MS OS.

[digitalradio] Tests of the MIL-STD-188-141A mode (ALE) and new modes Unproto and ARQ FAE
Hello to all, I have fixed (I believe so) the bug of the last test version of Mutipsk (25_02). Now, the soft decision Memory ARQ is normally available for ARQ FAE. This new test version in a ZIP test package is available in my site http://f6cte.free.fr/MULTIPSK_TEST_26_02_2007.ZIP (copy and paste this adress in Internet Explorer (or equivalent) Net adress field). It contains the Multipsk test version, the help files (in English and French) and the specifications (in English) of the ARQ FAE mode. Create a tempory folder (C:/TEST, for example), unzip the files in it and start C:\TEST\TEST\Multipsk.exe (the auxiliary files will be created automatically). 73 Patrick
[digitalradio] HRD log and PSK31 Deluxe
I am using PSK31 Deluxe in HRD and trying to use the HRD log and am having a problem. I am not using HRD for remote of the rig and am just using PSK31 Deluxe and the log book. The problem is that when I am in PSK31 Deluxe and I try to add a record to the log I get a error saying that I need to have HRD open. With PSK31 Deluxe I should already have HRD running or at least that is my understanding. The log works great and PSK31 Deluxe also works great but they don't want to play together. Is there a way to use these two programs and not be using the remote features of HRD. Any Ideas ?? Thanks Gary KE7KPI

I hope your new ARQ mode will progress well and I would really love to see some comparisons vs other digital modes, especially vs Pactor 2 and 3, although I realise that it is early for this right now. BTW how can you operate your new ARQ FAE mode? Do you need USB and do you have to have your passband centered on 1500 HZ or something near there? Or will LSB do as well? I suppose it has to be USB and 1500 HZ just like other wide digital modes, or am I wrong? Keep up the good work OM. 73 de Demetre SV1UY
