WSPR

I tried a new mode last night … WSPR. Essentially a way of checking propagation. “WSPR implements a protocol designed for probing potential propagation paths with low-power transmissions.  Normal transmissions carry a station’s callsign, Maidenhead grid locator, and transmitter power in dBm.  The program can decode signals with S/N as low as -28 dB in a 2500 Hz bandwidth.  Stations with internet access can automatically upload their reception reports to a central database called WSPRnet, which includes a mapping facility.  To see a live version of the map pictured at top right, click here.”

Above you can see the results of my efforts. I was transmitting 5 watts with my 31-foot vertical on 20 meters and 40 meters (mostly 20 meters). It does give you a good idea where you’re being heard.

Low Bands Rule

Got on 80 & 40 last night and worked about 15 stations around 2300/0000. Signals were pretty STRONG … some peaking well above S9. Most of the contacts were East Coast and Midwest. I did hear W6B in LA, but wasn’t able to get in. Eighty meters was the real workhorse, and that’s on my 31-ft vertical … not the most efficient of antennas.

Stations that heard me on September 13/14th on 80m

The higher bands were crappy! Twenty was really bad here at my QTH. Usually, in the afternoon when I get home around 1430, there’s a few CW stations going, but all I could hear was the ARRL CW practice transmission and a few stations down in the mud.

New Portable/Mobile Antenna

Based on several good reviews, I’ve picked up a Silver Bullet 1000 Take-It-Along Antenna Kit from Wolf River Coils. It consists of 3 – 33-foot radials, a tripod, an adjustable coil, and a 120-inch adjustable whip. Works from 80 through 10 meters. Quick setup and reasonable performance.

They were out of stock when I checked, so I looked at the “Lite” model, which is the same without the adjustable whip (and cheaper), and that was in stock. Guess they’re out of whips! I ordered a whip from Buddipole, and all’s well now.

Yeah, I know an inverted-V or a dipole would be more efficient, BUT … if it pans out, it should be the perfect tool for rapid setup in parks and portable operations. As a bonus, I could use it on the truck as well with a mag mount.

I just love experimenting with antennas!

JTAlert-X Update

Well, the issues that I was experiencing with JTAlert-X in my last post seem to have been resolved with that latest revision (2.10.0). Good job and quick work! I gather from what I read that the previous version was not a full implementation of WSJT-X rc1.

Still plugging away with the new mode. The band segment is still quite crowded, and it’s sometimes difficult to squeeze in.

I’ve been trying to fit some antenna work in, but with the heat index at 100+F lately, it’s been difficult. I’ve pretty much got everything I need now to get my Cobweb in the air, except for the wall mount for the mast, and that’s on order. I’ve been slow rolling this job, but am determined to finish it up soon.

I’ve got other yard work to tend to as well. A fast-growing vine has nearly taken over the back porch and one side of the house. I thought I had killed it, but it seems to have come back from the dead. I also have a tree down next to the property line with my neighbor to the rear … it came from his yard, but it’s mine now, since it’s laying in my yard! It’s not a big tree, so I should be able to work some chain saw magic on it.

That’s about all for now … stay tuned …

Looking up …

Not literally … I meant that conditions improved quite a bit over the past couple of days. Forty meters really seems to be the workhorse, but twenty had its moments. I was working JT-65 and JT-9 with one hand, while doing some catching up on paperwork with the other and the waterfall was full, with stations stacked on top of stations. I would transmit a CQ and at least two stations would decode coming back to me. Midwest, East coast, and Europe were all workable. Lots of fun!

Yesterday afternoon, I adjusted the hamsticks for my truck using my handy-dandy MINI60 Antenna Analyzer. Yes, I parted with my hard-earned cash and I must say, I’m really pleased with the device. It’s well-built and does what it’s supposed to. With the Bluetooth linked to my smartphone, It’s easy to see where the resonance is … the answer is just a scan away. I’m hoping to get some portable operations in from some nearby parks soon, now that the weather is nice.

So, I’ll catch you later.

Updates

I did get on yesterday afternoon, using JT-9 and had propagation into the US and Europe. My signal reports were not great, but were obviously sufficient for QSOs. I was hearing them much stronger (in most cases) than they were hearing me. I have GOT to get out this weekend and try to get my Cobwebb antenna put together and raised. Now that the weather is improved, I really don’t have any excuses. I guess it’ll REALLY upset me if it doesn’t perform better than my homebrew wire vertical!

I’ve been looking at the SARK-100 MINI-60 Antenna Analyzer and AM impressed. I have a MFJ-295 and it works fine, but a graphical analyzer (with BlueTooth now, as well as USB!) and functional PC and Android software is almost too good to pass up at the price point (~$140). If I keep on like this, I’ll eventually talk myself into springing for it. That’s how it usually winds up!

Well, back to work … later!

On again!

Well, I’ve been somewhat of a slacker … my last sustained activity was in February. I just had an accumulation of things that couldn’t be put off any longer that took precedence. I’m still not out of the woods, but I can see the light at the end of the tunnel!

I have managed to get some JT activity the past couple of days. Yesterday, in particular, seemed to be pretty good propagation during the early afternoon, but I didn’t have the time to get much operating done. Ah, well … I can only hope!

The weather is decidedly more cooperative lately, so maybe I’ll have a chance to get the cobweb antenna up, and do some portable operations from the truck as well. I checked out my FT-817ND and the associated mobile and portable goodies the other evening, and I think I’m OK there.

I got a couple of QSL cards this week, too! That’s an unusual occurrence for me nowadays. Back in the “good old days,” it was NOT unusual to get a few cards every week. Of course, when I was rare DX, I used to get LOTS of cards every week. Times change.

Well, I’m about finished my lunch break at work, so let me get back to work. See you later …

80 Meter Activity and Antennas

Eighty meters was pretty good at the QTH here last evening. Made contacts on JT9 up and down the East Coast. The QRN was minimal, and some stations were pretty strong, too. It’s the best I’ve seen it in quite a while.

It amazes me that my 31-foot wire vertical loads so well on 80 meters, too. The LDG tuner grinds a bit, but it does find a match. I don’t want to think about the efficiency of that antenna. The inverted-L is a disappointment though … nowhere near as good as the vertical and much noisier. I had the thought last night that maybe the coax is not up to snuff. It’s probably around twenty years old, even though it’s only been in use for maybe five years. I think I’ll substitute a new piece and see if that makes any difference.

I’ve got a new MFJ-1835 Cobweb antenna, still in the box. The weather hasn’t been cooperating since it arrived, and I’m hoping for some reasonable temperatures the week before Christmas, because I’m taking vacation then. I’ve read some pretty good reviews, and am really interested in experimenting with this antenna.

Hope everybody has a great Holiday season …

Catching Up …

There’s not much new to report, especially on the operating front, but I do have some new antenna news. Yesterday, I ordered an MFJ-1835 Cobweb antenna, and it is due to be delivered by the big brown truck today from HRO. Can’t beat their shipping and service. There have been some pretty good reviews in the forums and on YouTube, so I decided to go ahead and pick up one.When I get it assembled and up in the air, I’ll report further.

Last night was the combined PARC/SPARK clubs Holiday Banquet at Angelo’s. and it was a really good turnout, at least from the SPARK membership. PARC only had a handful of members present. The food and fellowship was great, as was the service, and the XYL even found someone she knew there to talk to.
