Default Is it me, or are the SW airwaves dead lately?

Not sure whether it's my region, the change in season, or something else, but I've never experienced such deadness on the air until recently.

It totally put me off the idea of getting another SW receiver. I had bought a new Eton E1, but it arrived with scratches and a misaligned tuning wheel. I was going to exchange when I decided to really try it out. I did, with both the whip and attached to my simple longwire antenna attached to a PAR EF SWL.

The thing picked up just about nothing over 7Mhz. No WWV at 10 or 15. Even below it, there were fewer stations on there. Until recently, the 9500-12000Khz range was popping with SW stations. Admittedly, mostly Radio Moscow, Radio China and evangelics, but still popping nonetheless.

But before blaming the radio, I also tried my Sony ICF-2010 (whip only) and my JRC NRD 545 (attached to the same longwire). Both of these were dead over 9Mhzl. With the 545 I couldn't even pull in the SSB CW signals in the beginning of the 7Mhz band.

In any case, I ended up returning the Eton. Just not worth it.

Now, I realize the change of seasons means that higher frequencies will be harder to receive, but I was able to pull in nearly everything from 7-11 Mhz when I put up my longwire last March.

Anyone have a similar situation?

Cool

Have you checked your antenna outside to see if it's in working order? Strange things can happen to antennas over time...

I been having good signals at my QTH for the last few weeks. I have a R75 and KA1103 - both are using only a long wire.

I too, have noticed this past week, with an R390 on one antenna and a Palstar R30CC on a different antenna that signals from 9 to 17 Mhz have been much lower!

What have the solar indices been doing as of late? (solar flux, A index, K index) Make it a routine to tune into WWV or WWVH and check those once in a while. Don't know how to do that? What do they mean? Google is your friend! Or check the RadRef Wiki.

Yes.. the solar flux was 81 last weekend but dropped back down to 71 by midweek. Today listening was much better, but I didn't listen to WWV to hear the solar report. That's propogation on HF for you, there are days no matter what the solar flux is, reception can be awful. Waiting a few days can make a big difference and reception can turn around in your favor!

Well, I went back on around 6:00 EST last night and suddenly reception was much, much better in the 7-12Mhz band. I didn't make any changes to my antenna or receivers or anything, so I assume it just must have been a bad week. Not a great time to test out a Eton E1, I guess, which I sent back to Universal for other reasons anyway.

Let's hope this patterns sticks up for a while.
