Thanksgiving weekend has come and gone and we’re into December and nearing the end of 2020. The good news is the economy appears to be holding up, although it’s a little hard to understand it with all that’s going on.
We had a quiet Thanksgiving feast – it was just Donna and me. I put a turkey breast in the Traeger wood pellet-fired smoker grill and gave it a little over an hour at 350-375. In the final 10 or 15 minutes, I upped the temperature to 450 to crisp the skin. It came out beautiful and tasty. Meanwhile, Donna prepared Brussel sprouts with a horseradish cream sauce and corn with sun dried tomatoes and parsley. And of course, mashed potatoes and gravy!
Neither of us are big dessert eaters – we rarely eat sweets – so we passed on the dessert. If our microwave/convection oven had been operational, Donna might have made a pumpkin pie – in fact, I’m sure she would have.
I spent some time in the ham shack playing on the radio Friday and made contact with Haru (JA1CG) in Japan again. I also had conversations with Dale in Texas – he’s frequently on the 20-meter band and a guy named Grant in Carlsbad, California. I’m really enjoying the ham radio hobby.
My ham shack is unconventional – as you can imagine, it’s difficult to have an actual shack with our nomadic lifestyle. I set up under the canopy Donna bought for my birthday and put the power supply and transceivers on a table. I leave my antennas mounted in tripods, but I pack up the things on the table when I’m finished for the day. It wouldn’t be good to leave my expensive radio gear out on the table!
I’ve mentioned using various frequency bands and the differences before, but I’ll try to explain it again. The three main frequency categories for amateur radio are High Frequency (HF) which is 3 Mega Hertz (MHz) to 30 MHz. Then there’s Very High Frequency (VHF) which is 30 MHz to 300 MHz and then Ultra High Frequency which is 300 MHz to 3000 MHz.
High Frequency transmissions can typically cover very long distances. The VHF and UHF frequencies are limited to line of sight under most conditions – actually, they can travel just beyond the visible horizon. For this reason, there are repeater stations for VHF and UHF. These repeaters receive the transmission from a ham radio within range, then almost simultaneously re-transmit it at a higher power level, usually from a tower mounted at higher elevation. This allows the signal to be “repeated” over a larger area.
Many repeaters are also linked via various programs to other distant repeaters through the Internet, thus providing worldwide coverage. To use a repeater, a few parameters must programmed into the transmitter. For one thing, the repeater will receive the signal on one frequency and re-transmit the signal on a different frequency. This is called offset and is necessary because it can’t receive and transmit on one frequency at the same time.
When we use HF, we are communicating through a direct (simplex) connection antenna-to-antenna.
In the photo above, it’s pretty straight forward. I’m receiving a signal from someone transmitting on 14.250 MHz. Once he finishes talking, I’ll press the push-to-talk button on my microphone and transmit on 14.250 MHz back to him. This is good old fashioned simplex operation.
In the next photo, I’m using a lot of technology. In the upper left of the screen, the WIRES-X icon is activated. This means I’m connected to the Yaesu WIRES-X Voice Over Internet Protocol system. The 440.375 is the UHF frequency I’m receiving. Below that it shows 445.375 MHz – this is the UHF frequency I’m transmitting to the repeater on. Since I’m in a digital mode, more information is displayed. It shows I’m on the East Valley Repeater Group (EVRG) repeater that’s registered in Gilbert, Arizona. The actual equipment is on South Mountain in Phoenix. Below that, it shows America-Ragchew, that’s the “chat room” I’ve selected. Whew! Enough radio talk.
I ordered a replacement microwave/convection oven and received it shortly after we arrived here at Viewpoint Golf and RV Resort. I had an appointment with Sean – he operates Valley RV Service, a mobile RV repair service. Sean stayed in contact via text messaging and showed up here yesterday as promised. He muscled the old oven out of the cabinetry in short order.
As you can see in the photo, the old oven was showing its age. The button to release the oven door came off and the linkage behind it was irreparably broken.
The replacement oven, being nearly 20 years newer, is slightly different. Although Sharp lists it as the replacement model, it has slightly different dimensions and more programmable functions. It’s also heavier than the old one, which was plenty hefty. Sean had a few issues to overcome getting the new one mounted. I helped him hold it in place while we fiddled with the bolts securing it to the mounting bracket. It took several attempts to get it in place, but we got it done!
I didn’t mind lending Sean a hand, although I was paying for his service. His rates are fair and there’s no way I could have handled it myself. The reflections on the surface of the new unit made it hard to photograph, but I used the photo anyway.
On Monday morning, we had the first round-robin pickleball event. Unfortunately, it was very windy with unpredictable gusts. This made every game a matter of luck more than skill. My game relies on shot selection and placement – it doesn’t work very well in those conditions. Today, I’ll run my first coaching session of the season at noon and wouldn’t you know it – gusty wind again!
The temperatures have reached the low-to-mid 70s each day. Today the forecast calls for a high of just 64 degrees with clear skies. The mid 60s are forecast for the next few days before we warm back up to the 70s over the weekend. I can stand that!
