Since there has been recent discussions on this reflector about JT65 on 1838, I thought I would pass this on. IMO, digital should go below 1810, AND it should preferably be a narrow band mode such as
IMO, digital should go below 1810, AND it should preferably be a narrow band mode such as the superior JT9 mode. Unfortunately, "below 1810" is never going to fly because of the lack of access below
Thank you. I forgot that in Region 1 (essentially Europe, Asia, & Africa), 160m starts at 1810. Here's a couple of thoughts for discussion: - Since two-thirds of the world --including North and South
Mike, - Since two-thirds of the world --including North and South America-- starts at 1800, why not consider region-specific band plans? Is digital popular in other places? Put it this way - if you w
Thanks, Joe. This is exactly the kind of input that we need here. :-) 1843? I believe you. In this area (SW MO) and at the times I tune around, I haven't heard much below 1850. I can think of regular
Apparently you did not read that URL. They're not even asking for 1810 to 1840. Equating RM-11708 with something the proposed band plan from the URL above DOES NOT EVEN ASK FOR, and giving that as a
Although they do not specifically ask for an allocation on 160 meters, their principle of 15% of every amateur band located the preferred spectrum for common access across all three regions is clear
FWIW, I believe such transceivers do exist. Don't the Flex SDRs have that capability? ... as if there are any amateur transceivers capable of operating with _________________ Topband Reflector Archiv
I'm sure there are some military/commercial systems that will do it but I don't believe that even the Flex are clean enough to handle the really wide band commercial data modulations. 73, ... Joe, W4
What the hell is the need for wideband data in the amateur radio bands? Is it just a ploy to usurp the amateur bands for commercial purposes? And there's a heck of a lot more band width available at
Yes - for the rich yachtsmen who buy ham tickets and then use the Winlink/Sailmail stuff in the amateur bands rather than pay for expensive maritime data service. There is none except to enrich cert
Mike, One of the problems with making band plans is that every region makes its own and then forget how things are arranged in other zones. In EU still a lot of the countries have only 1830-1850 avai
I think Henk's post makes very good sense. As to the limited use of JT9 -- it is a VERY new mode, released only within the past 18 months. Yes, it is superior, and hopefully will be adopted. But that
I just stumbled across this in the last ARRL Contest Update newsletter: Web Site of the Week - Ian G3NRW has updated the Band Utilization Charts for ... 160 meters. He asks to be notified by email if
