I am forwarding this to the list for discussion. I think it would be a good idea to coordinate this with the ALE people, and the frequencies do not look bad at all. Some time in the future we may want to further integrate pskmail and ALE, and this looks like a good starting point. What do you think? 73, Rein, PA0R PS: I will be field testing pskmail in northern Germany for the next week... new arq.pm in the snapshot with improved adaption algorithm and new preamble (tx call). -------- Forwarded Message -------- From: KQ6XA <expeditionradio@xxxxxxxxx> To: rein@xxxxxxxxxxxx Subject: Re: 10148kHz ALE and PSKmail Date: Wed, 20 Sep 2006 21:16:22 -0700 (PDT) Hi Rein, Thank you for the information and images of spectrum. I see there is a Winlink2000 PACTOR station, A71BY in Qatar, listed on center 10147.7kHz with PACTOR1/2/3. I do not see any other WL2K stations listed in Region 1 in this channel. I propose that we coordinate the PSKmail channels with ALE channels, so ALE and PSKmail compatibility may be possible in the future. May I please recommend a plan for PSKmail server channels? Please see the attached drawing image as an example of a typical ALE/PSKmail plan of the 30 meter band. 10145.5USB ALE/PSKmail (10147.00 psk center) 10148.50 (center) PSKmail Server 10148.75 (center) PSKmail Server 10149.00 (center) PSKmail Server ALE digital channels are located within the Automated- Unattended Station band segments. All ham ALE operation is USB. When PSKmail is combined with ALE, we could use the 1500Hz audio frequency standard for the PSK carrier. For stand-alone PSKmail servers without ALE, the basic channel plan may start at 3.00kHz above an ALE digital channel. On some bands, the PSKmail channel plan would start 1kHz below the ALE digital channel. PROPOSED ALE/PSKMAIL and SERVER/PSKmail CHANNELS: ALE=1845.0USB /PSKMAIL=1848.00 1848.25 1848.50 ALE=3517.0USB /PSKMAIL=3599.00 3599.25 3599.50(IARU R1) ALE=3626.0USB /PSKMAIL=3629.00 3629.25 3629.50(IARU R2) ALE=5371.5USB /PSKMAIL=5373.00 ALE=7040.5USB /PSKMAIL=7038.25 7038.50 7038.75(IARU R1) ALE=7102.0USB /PSKMAIL=7101.00 7101.25 7101.50(IARU R2) ALE=10145.5USB /PSKMAIL=10148.50 10148.75 10149.00 ALE=14100.5USB /PSKMAIL=14103.50 14103.75 14104.00 ALE=18106.0USB /PSKMAIL=18105.25 18105.50 18105.75 ALE=21117.5USB /PSKMAIL=21109.0 21109.25 21109.50 ALE=24926.0USB /PSKMAIL=24925.0 24925.25 24925.50 ALE=28146.0USB /PSKMAIL=28149.0 28149.25 28149.50 You will find some interesting new features in the new PCALE version that will soon be released this month. It includes GPS reporting and other things. Also, there is a fast PSK modem (188-110) and FTP (5066 type). Perhaps you can interface this with your server. The new PC-ALE has a software port to communicate with other programs. Best Regards, Bonnie KQ6XA
