One thing after another!

It’s been a typical 2020 weekend so far … wife had to have an epidural for pinched nerves that have been troubling her for months … the remnants of tropical storm Laura are just about upon us, with predictions of lots of rain, flooding, and even the possibility of tornadoes … the A/C started making funny noises last night, and then quit altogether … hope that’s it for the rest of the weekend!

But, looking on the bright side … the wife says the shot helped a lot, and she’s in a much better mood now … no pain. I sent a request for service to the home warranty company at 11 am, an A/C tech called at noon to say he was on the way, he arrived at 12:30 pm, and had the repair completed and function fully restored by 1 pm … IMPRESSIVE!! That was the first time I have used the warranty. And to top that off, the rain from the storm started just as he was replacing the last screw in the case! How about that!

Radiowise, not a lot happening at the moment. I continue with FT4/8 when I get a few free minutes, but these other things have kept me busy. POTA contacts are down … propagation has not smiled on me.

OH! We did get the repeater antennas up on the tower. Just waiting for a chance to install the UHF and VHF repeaters. Soon!

Storms and Parks

Wow … in less than an hour this morning, lots of parks to work if you’re interested in Parks on the Air.

After a couple of days of a power outage, I just turned on the radio this morning to see what the bands were like. Nothing spectacular, but certainly fruitful.

About a block from my QTH is a beautiful wooded street … the trees formed a green canopy over the pavement … great for scenery, but not when coupled with the high winds and heavy rain of a tropical storm. The falling branches took out most of the power lines, thus my lack of power at the house. I could have gotten up on battery power, but it was HOT as well, with no air conditioning.

We had our first radio club meeting in person (other than virtual), since March, last night. Attendance was pretty sparse, but that was to be expected. Non-essential meetings are not a priority right now. Also, missing was the social get together for a meal beforehand. Next month, we’re planning a hybrid meeting, with both physical and virtual attendance provided for.

Well, I’ll close this for now and see what else I can find on the bands, and then see about finding some lunch. Most of the food in the fridge was a casualty of the power outage … got to look into a new generator soon.

“Interference”

I’ve been going crazy trying to track down an interfering signal that showed up recently on my FLDIGI waterfall.

Finally, I connected the RSP1A to the antenna and lo and behold, there was nothing there! It had to be something with the radio. Not only that, but it was there when changing the frequency and band … never moving on the display.

What could it be? DING DING DING !!!!! Operator ERROR!

Somehow I had fat-fingered the Notch on the IC-7300. Don’t remember doing it, but I sure did! Deselect the Notch and back to normal..

Getting My ALC Under Control

I’ve been doing a lot of digital operations, as I remarked earlier. I haven’t done any PSK-31 QSOs yet. I thought I had everything set up, but found that the IC-7300 was hitting the ALC pretty hard … too hard for my preferences.

I started digging with good ol’ Google, and found several solutions, but the best (for me) that I found was this page by K0PIR . There’s a balancing act, and it took me a bit of back and forth to reach a compromise for WSJT-X and FLDIGI. I think I’ve got it now, though.I show NO ALC using WSJT-X and about 50% of the “safe” ALC zone of the ALC meter.

Again!

I had my IC-7300 reset again in the middle of a QSO. Irritating, to say the least. I thought I had the problem solved, but evidently not.

The Samlex power supply output terminals require that you insert the power wires into them and then tighten setscrews to secure the wires and make good electrical contact. A wiggle of the wires showed that there was nothing secure about the connection, even though the screws were tight.

I did some reading, and found that the power supply manual stated that the wires inserted into the terminals should be soldered. If not, the individual strands could distort and present a reduced cross-section and thus, a reduced current-carrying capacity.

I applied solder to the power cable ends, bonding all the wires together, and then reconnected them to the power supply. I put the system through the ringer … key down, max current draw, and no reset was noted. Problem solved … I hope!
