[digitalradio] Re: QRM maker on 14.078 CF
Further information ref, QRM... This callsign comes up HB9CAP and SM5MCZ. The Switzerland callsign is allocated to a Sailing Consultancy;- Web Pagehttp://www.sailconsult.ch I have emailed him explaining the problem of interference. email sentDear sir, Your callsign has been seen on the frequency of 14.07600 on an RTTY message. Would you be so kind as to tell the owner of the RTTY transmission that he is serioulsy interfering with the Very Low Power Experiments taking place around that frequency. It is suggested that he move his tranbsmuission above the 14.101000 Mhz where mailboxes are accustomed to operate.

Re: [digitalradio] 60M, FCC, and ALE
Andy, Just two-cents worth here. ALE400 forces the user into one software package and operating system at the expense of others. Of course, there is virtualization technologies to help with that, but unless ALE400 gets more widely adopted it likely isn't the answer as a specified signal of interest in any amateur band. Of course, I like where you are going with thatI'd much rather see multiple channels of narrow-band ALE in the bandwidth of one normal ALE signal. Another proposal might be to limit the ALE (and Pactor III that was proposed) to only one of the 60m channels, while allowing voice on all the others. I think PSK31 was also proposed, but I suspect that it was included simply to throw people off of the trail of ARRL's 60m EMCOMM grab. The problem with trying to setup 60m as an EMCOMM band (supporting ALE, Pactor III and the like) is that on 60m, we are second class citizens. The same characteristics that make 60m attractive to hams during an emergency make it attractive to the government as well. As long as we have to operate on a not-to-interfere basis, 60m will never be a viable EMCOMM band. FEMA, DHS, MARS, and others will grab all of the spectrum and there will be no room left for amateurs during a true regional or nationwide emergency. We already see that with the request to move one of the 60m frequencies due to continuing interference from a permanent station on the freq. I'm sure all of our other frequencies have government-authorized users that WILL show up during an emergency, effectively removing one or more channels on a regional or even nationwide basic.

The article suggests that the FCC is encouraging consideration of ALE for that band. That part slipped my attention when we discussed this topic last month. I'm an ALE fan , but not ALE as unsuccessfully advocated by HFLINK (although they have had more success with their ideas, than I have had with mine!). I wonder if the request for comments is an opportunity to promote the concepts of ALE 400 for 60M? Seems to me that 60M would be an ideal band for any ALE but especially for ALE 400. Andy K3UK --
[digitalradio] K3UK gone over to the dark side...
OK, I did it. No, I have not become a Pactor III BBS but I have set up a 24/7 WINMOR Winlink 2000 server station with busy detect active at the server end preventing my response to a connect request if the frequency is busy.. This station will use 500 Hz Winmor. The first couple of stations connecting to the server (K3UK-5) all passed traffic to the CMS server OK.I need to study frequencies more and make sure that I eventually choose frequencies that make sense . During the next few days I will test on 0500 to 1400 on USB 3584.5 (dial 3583). 1400-1600 USB 7084.8 (dial 7083.3) 1600-0100 USB 28125 dial 2100-0500 USB 7084.8 (dial 7083.3) 10M is NOT a mistake. There are no servers on 10M and I hope to test this out some more. I may also try 6M. To use the server, you need RMS express software, which is free. You also need a soundcard (and radio!) I've tried PSKmail , ALE400, and 300 baud packet Pbbs over the past few months. PSKMAIL is VERY good but the Linux requirement for the server operations was more than i was willing to mess around with. So, I will give the WINMOR winlink server a try for the next 90 days and then evaluate how utilized it is. This will also give me a great opportunity to fully study the busy detect features that appear to work quite well at the moment.
