Topband: Poor conditions in 2018 so far for working VK6 to NA long path

G'day With the exception of last Sunday I've been on 160m for east coast NA sunset from 7/11/18 until 12/11/18 to try to give out some ‘long path’ contacts with USA/VE. Although there has been some spotlight propagation into Europe (today was Southern Europe/North Africa and S01WS for a new

Topbanders. . . Although my geographic perspective is much different than Steve's, I concur that conditions so far this season have been very poor with the exception of an occasional bright spot. . . many nights/mornings being remarkably poor. Far inland here in the Midwest (Iowa) I go night

Topband: condx 160m last days

Hey from DL, i tested the last weeks my new beverages, and I can say now, band is mostly open USA to EU the last weeks at 4.00 UTC and 22.30 UTC. I heard many US stations and worked KC1XX, NP4Z, 8P9AE, K0ZK,W1UE, NY2PO... So hope to work you the next weeks on topband vy 73 Andy

Hi all, I’m not sure if there is a low bands chat group on any of the chat apps (please advise). I herein suggest to have a chat group on Telegram application. Anyone with an Android or iOS mobile would have access to the that chat group. I know most of the lowbanders want to be old fashioned

Re: Topband: 160m Condx

Concur . if a frequency either ends with a zero, or if you add the digits up and get a number divisible by 9, it will likely have a greater change for BC interference. Example in Tampa (Florida, US) is 1860, which is the 3rd harmonic for WDAE 620, which is a 50kW stn. An example for our

Topband: roasting earthworms

the morning after a wind and lightning storm i found that i had a 20 over nine power-line noise problem on 160 meters  on my triband beam it peaked north east on 20 meters     i waited a couple of days to do anything about it because i knew that our small electric cooperative was overwhelmed

Re: Topband: 160m Condx

Aren't US and Canadian broadcast stations on frequencies that are divisible by 10, like 900, 910, 920 kHz? That would place harmonics on 1800, 1820, 1840, etc. I think I read somewhere before that European broadcast stations are separated by 9 kHz. Could be remembering wrong about that, though.

Re: Topband: 160m Condx

I wish we could get the word out to avoid frequencies like that: 1810, 1820, 1830, etc. There are almost always AM BC harmonics on those freqs. 73, Mike www.w0btu.com On Sun, Nov 11, 2018 at 4:24 PM k1zm--- via Topband wrote: > > Band still down a bit from last week but 4k6fo good sigs now on

Filipe: In the USA and Canada: 1810, 1820, 1830, 1840, 1850, 1860, 1870, 1880, 1890, and every 10 KHz through 2000 KHz. I missed some Eastern Europeans because they TX on 1870 in CQWW CW Contest and we have loud 'birdie" signal from two nearby AM broadcast stations near my QTH. 73, George,

Re: Topband: 160m Condx

Know bad frequencies- great resource here: http://www.k8nd.com/TopbandBadFreqs.pdf However…a “best practice” on 160m is NEVER call CQ on an exact frequency. Why is it ever necessary to call on 1830, 1820, 1822 etc. exactly? Call CQ on 1820.3, or 1820.4

Re: Topband: 160m Condx

A related issue is that frequencies ending in 0 and 5 tend to attract casual operators who can't hear DX. Many times I have heard them start up and call CQ on top of DX. I like to choose a frequency ending in 2.5 to avoid the casual ops. On the high end of 40, this neatly avoids BCB stations,

Re: Topband: 160m Condx

Just as a reminder to all that these BCI problems can also occur at 2nd and 3rd order IMD mixing. Example 3rd order, one station on 1220 where 2X equals 2440 and a second station at 620 subtracted puts a 3rd order product right on 1820 . Another example 3rd order, is 2 stations at 600 where 2X

David -- Suggest you take a look at the attached paper by Jim Brown. I live in a fairly dense suburb where every house (including mine) has all the latest RF noise-makers. Following Brown's suggestions, I've put large 31-material clamp-on ferrites on both ends of my receive antenna feedlines
