Re: Topband: ARRL 160M and 1830-1835 change

george, i believe that those stations who have key clicks are truly not aware of their problems.  a private email to the offending station may cure the problem. i really cant conceive that someone would do this on purpose, especially on top band. larry    n7dd -Original Message- From:

Re: Topband: ARRL 160M and 1830-1835 change

Tim, You are right. In theory the window could work. But the problem is that those (non-DX) who violate the rules suffer no consequences. Therefore, those with the cheek gain an advantage. But,.. A much (much) bigger problem is stations with strong clicks. I believe that some may be

Hello This been into global bandplanning by IARU 80,40m also have contest free segments actually ! For those who want to run DX qso non contest 80m 3500-3510 KHz DX window 80m 3650-3700 Khz 80m 3790-3800 KHz DX window 40m 7100-7130 KHz 7110 is Emergency QRG 20m 14100-14125 KHz Now 1830-1835

Re: Topband: ARRL 160M and 1830-1835 change

George, in ARRL 160 the DX would *only* be looking for W/VE if CQing during the contest. So the DX Window concept has some value (if anyone ever respected it which they didn’t). This is a fundamental difference from CQ160 where DX can work DX for points. Arguably DX-only-works-W/VE makes ARRL

Re: Topband: ARRL 160M and 1830-1835 change

If 1,830 - 1,835 is reserved for "intercontinental contacts", who will should CQ? The DX? He is not a DX on his own continent. These "DX windows" are not practical. 73, George C6AGU/AA7JV On Thu, 22 Oct 2020 14:43:52 + (UTC) Jon Zaimes via Topband wrote: Interesting Tim. November QST

FYI, since the genuine 2N5109 is so difficult to source (and the 2N3866), you might want to look at using a DCP68. This is a surface mount device that will electrically replace the 2N5109 in the W7IUV preamp provided you don't need to operate it at frequencies higher than 3 Mhz. I have

Topband: Wednesday CW DX Activity Night

Good to see quite a lot of stations on last night, from both sides of the pond. Conditions were reasonable, and I certainly worked every NA station I heard. Thanks to all those that made the effort to come on, and hopefully we'll have even more next Wednesday night ! 73 Roger G3YRO

Re: Topband: ARRL 160M and 1830-1835 change

I think the 1.830-1.835 rule had been removed and reinstated at least once before (maybe back in the 90's?). While the ARRL contest portal is great, I'm not sure where to find archived copies of rules for previous years. I have a query out to the ARRL contest desk but maybe the 160 experts here

Re: Topband: ARRL 160M and 1830-1835 change

this segment never was respected, so it is good to eliminate it to avoid yearly debate about that :-) 73, Jorge CX6VM/CW5W Libre de virus. www.avast.com

Interesting Tim. November QST came in a few days ago, and the summary of rules in there says "1.830-1.835 MHz should be used for intercontinental contacts only." Dropping that rule was long overdue so glad to see it stated in the rules online.  73/Jon AA1K -Original Message- From: Tim

I saw some news about JA frequency/mode allocations changing in the past year and seem to recall new frequencies available for data and phone. For plain old 160 Meter CW - is the JA Window still 1.810 through 1.825 MHz? Tim N3QE _ Searchable Archives:
