Title: HF lousy
Post by: N4GKS on January 12, 2014, 06:48:29 PM
75, 20 and 40 have been horrible for even local QSO's. Was this predicted or is this just lousy for HF?

Are you following normal propagation for these bands or checked your antenna? No problems here for 20/40m DX anyway.

According to the last solar news report, there was suppose to be a big geomagnetic disturbance but it did not materialize.

Thanks Zack

This is the reason why I do not pay attention to people when they make this kind of claim, or when they claim that you cannot work people, even during a solar flare event.  That is technically what happened this last week.
Even poor band conditions like that, enhances the lower bands such as 15, 10 and 6 and really creates band openings even on FM on 2 meters.

This has been a week of strong solar storms, with major HF fades and blackouts, and polar auroras.

Many tools are available to keep alerted, and see present and forecast conditions:

tools split to new thread.

No, it has been noisy and poor for the past few days. Strange conditions because somehow I managed to work Italy on 75 meters for the first time last night, go figure!

I can attest to at least 40 being a nite mare when all stateside in dark conditions, however East dx from NY holds up pretty well during same time frame.
This happens every year around this season so nothing unusual from my location.
While running the OMISS net at 0100, I always lose 8 and 9 call district with 0's following shortly at 0200 like a light switch.
At same time with east beam, Europe and SA loud.
Have been dealing with this for many years I know that actual prop predictions have little effect unless a full blown CME blast is in progress.
Always cringe when some expert claims that 40 meters is a great winter band in the dark! I'll take the spring thru Fall lightning static with consistent prop anytime.

The bands have been all over the place. From totally dead one day to JA, Zl and Vks booming in the next.  I think a lot of Dx stations have just been sitting it out until the numbers settle down a bit.

On the 12th I worked Australia on 40.  On the 8th I worked Namibia 30 and Australia on 40.

Last night I worked Maine on 40 for state #48, W1AW/3 on 160, and then Montana for #49 on 40M.  The Montana station had a really good signal on my 160M top loaded vertical--but he wasn't having much luck working the station in Maine.  I think I'm going to add some 40M radials to the 160M vertical--I just tied it into my 80M radial system as a quick and easy ground.

Well, I have been consistently working Europe almost every morning on 40M long-path the past 4 weeks using 5W.  Best report late last week was 589 from DJ6ZM (he was 569 using 10W on his end).  40M has been mostly OK, notwithstanding occasional solar events.  A friend in Nevada had similar results with some QRP contacts to EU to validate my recent results.

I am a proponent of using SW broadcast stations from various parts of the world as a benchmark of the overall band(s) condition.  I agree that the upper bands (10-20M) have been schizophrenic of late but it just seems to be a reflection of the current solar flux situation.  For instance, last week we were supposed to get blasted from a CME with an accompanying NOAA warning to airline travelers, so I figured the HF bands would be dead the following day.  That following day, not only was propagation not negatively affected, it ended up that conditions were the fantastic on 20M, 30M and 40M.

It is clear to me that the lower bands will be the most predictable over the coming years and we have already seen the best from solar cycle 24.  So if you're looking for predictability, gravitate to the lower HF bands.
