There it is again …

I had that problem pop up again where my output power in WSJT-X dropped to 5 watts and I couldn’t increase it. I fiddled and fiddled with settings and turned knobs and fiddled some more to no avail. Still good power out with FLDIGI and on CW, etc. So, that seemed to be a good time to have dinner. I returned from dinner and lo and behold, everything was back to normal. Windows 10 had just finished its big Fall update earlier in the day, so maybe that had something to do with it? Still an unknown …

I made a few FT-8 contacts on 80 meters, and a few more on 40 and 30, but 20, which is usually pretty good, just wasn’t cooperating with me last night. I tried calling CQ on JT-9 on several bands without any luck. Although I like the speed of FT-8, I like the sensitivity of JT-9 better. It can really pull the signals out of the mud.

Saturday I’m going to the QCWA Chapter 119 luncheon. Twice a year, it’s on my side of Hampton Roads (Newport News vs Virginia Beach). It’s the only time I get to see some of these guys. I’m not sure what the program is about, but it’s usually pretty interesting.

There’s a real chill in the air, now. Fall is officially and truly here. The past couple of mornings, it’s been in the 40’s when I leave for work at 5:30 AM. Used the heat in the house for the first time this season just the other night. Yep … Winter is coming!

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.

WSJT-X 1.8.0 rc2

The latest release candidate of the WSJT-X software incorporating FT-8 mode has been released (rc2), and it seems to have cured my power output problem. I worked several stations on 20, 17, and 15 meters this afternoon and everything looks ok — JT65, JT9, and FT8 all worked great.

The bands seem OK today … much better than the recent past. Hopefully I’ll be able to get on later this evening to see who’s about. It’s a dreary day outside with thunderstorms in the forecast so that might put a damper on later operations but hey … that’s ham radio, isn’t it?

More FT8 Stuff …

OK, I played with the new mode for a while last night, and feel a little better talking about it now. FT8 is a new mode with a lot of interest. Twenty meters at times was wall-to-wall with signals on my waterfall, without a space to squeeze in … definitely lots of people trying it out!

As I mentioned before, it’s FAST! If you’re used to JT65 or JT9 modes, it’s a screamer. It’s almost unnerving to try and keep up. Remember when you were scrambling when you first started learning and using the JT modes? Well, this is that experience on steroids. It’ll get more calm as I get more familiar with it.

I did notice a couple of anomalies while I was operating. JTAlert-X (2.9.10, the compatible version) sometimes seemed to not populate the boxes with the decoded callsigns. Not always, but sometimes. Another odd thing was the auto-sequencing ( a new feature) worked well, except for one solitary station that tried to work me twice. In response to his signal report to me, WSJT-X should have replied with my signal report to him. WSJT-X kept transmitting the “RRR” exchange. Every single other one of the 13 QSOs that I had last evening performed flawlessly. Not sure if it was the software or something he had wrong, although I would suspect the latter. We need to remember that this is a release candidate software, not the final, polished software. They’re still ironing out the kinks, and a few glitches are to be expected. Overall, this is a gem of a program.

It’s a learning curve, but worth the effort. Another arrow in the quiver to nail the elusive QSO. My congratulations to K1JT (who, by the way, I worked on FT8 last night) and his crew for their hard work! Well done!

73 and see you on the bands,

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!

In a Real Rut

I seem to have settled into a rut lately. I get home from work, turn on the rig, and work a few JT-9 contacts, and then shut down. I think I need a bit more spice in my life :-). I hereby resolve to try and inject more variety into my ham radio practices. This weekend, I think I’ll do a bit of PSK and a bit of CW, and MAYBE even a little SSB. If it wasn’t so darned hot and humid (106 deg. heat index), I might even venture a little antenna work and generator servicing.

I’m at work right now waiting for the HVAC guy to show up and service the failed A/C unit at one of our radio sites. I don’t like to see high-temp alarms at my sites!

I just finished up a week long class today on Motorola Networking Essentials. I learned a lot and am looking forward to more classes this summer. These classes are a result of us updating our analog trunking system with a new P25 digital trunking system. It’s all IP-based, so networking is an integral part of the infrastructure.

I worked with Tom, WE4TOM, to get his PSK31 up and running. We only live a couple of miles apart, at most, but it was great when I finally saw his transmission on my waterfall and printing out on my screen.

We had tried a couple of times over the past two weeks to get something going. He could copy my transmissions, but I wan’t getting a whisper from him. I still don’t know what he did to get it working, but after a couple of iterations, HE DID! Sometimes you have to keep banging away at the problem until you get a break.

So Tom … guess what I’ve got for you? That’s right – a shiny new QSL card. I’ll deliver it at the next Club meeting. Great job of figuring out HRD and DM780. Here’s a preview …

More Digital Thoughts

Well, I’ve been using JT-65/JT-9 for several days now, and I do have a few thoughts to share. It’s amazing being able to copy a signal you can hardly see on the waterfall or hear. As a weak-signal mode, it is really unsurpassed. I’ve been using 5 to 10 watts output and find that more than sufficient in most cases. Using WSJT-X software from K1JT, it’s almost foolproof once you’ve got a few QSOs under your belt.

For me, the biggest negative is the limited ability to actually say anything of consequence. With a 13-character limit on your message — well, that’s not a lot of chat time. But all this has been said before, and it is what it is. Within the constraints of the format, it works exceedingly well.

It’s been a while since I’ve dabbled in the more verbose digital modes, so I’m going to try to get back to the “keyboard” modes for a while (PSK-31/63, etc. While the JT-x modes are great for propagation research (pskreporter) and snagging some new ones relatively easily, I think I prefer the more free-structured keyboard-to-keyboard, give and take of the more conventional modes.
