Almost Ready

Thursday - The day started out cool-ish, but it was pretty warm and muggy by the afternoon. I was able to hit the Brownsville Winlink RMS station this morning to pick up my Winlink email, al6t@winlink.org. BTW, RMS = Radio Mail Server in case you were wondering. Very little FT8 activity on 40m today. I think I picked up only a handful of new contacts. All of them under 500miles. I switched to 20m and picked up an additional seven contacts almost immediately.

I laid out most of my hand tools today to try to figure out which ones I might need this summer. Unfortunately, that amounted to most of them. I picked up another zip-top toolbag since the old knapsack I was using had developed some large tears over the years. It was one of the vendor freebies from a conference.

Bridget noticed that the skylight over the shower was dripping water into the shower, so I just picked up a couple of tubes of Dicor self-leveling sealant to re-seal the skylight. 

Friday - The first thing this morning, even before coffee, I went up on the roof of the class C to add another bead of Dicor around the shower vent. There were some possible leaks, but nothing obvious. No cracks in the existing sealant. There was another dab of old Dicor in the middle of the roof, so I just cleaned the spot and added another layer of Dicor on top of it.

I tried FT8 on 40m again today but got very few contacts. I was too lazy to adjust the antenna to 20m as it was hot and muggy all afternoon.

Still Packing and Winlink-Wednesday

Wednesday - We've been getting lots of storms lately. This was last night. It was windy with rain, but not as much as the surrounding area. This morning, while walking to coffee, the streets weren't as flooded as they were after similar storms. There was some debris from trees, again, not as much as in some other storms.

It was clear, hot, sunny, and very humid by the afternoon. I continued to move stuff out of the class A and the shed into the class C that I "needed" for this summer trip. I don't plan on taking the Blackstone griddle or the large Starlink storage container this time. I moved the portable refrigerator/freezer and plugged it in. Since we picked up the small refrigerator for the shed, we don't have to bring all of the refrigerator/freezer items with us like we did last summer. The portable unit will actually get real use on this trip.

I still plan to bring the ham radio with me and this time I plan to bring the ATAS-120 antenna. I had forgotten it last year.

I checked in with Winlink-Wednesday again on 40m. This just means that I sent a specially formatted email message using the radio as the transport. I used an RMS stations in Lubbock and Brownsville. The JPC-12 vertical antenna worked well. Very low bit rate as in sub-1200baud modem speed. 

Still Getting Tasks Done

Monday - I helped out in the kitchen today for a Memorial Day lunch. The lunch was good, as usual, as was the conversation. 

This morning, before it got too warm, I changed the oil on the 4K Onan generator on the class C. After finishing, I ran it for around 10 minutes just to ensure some fresh gas made it into the carburetor. There wasn’t much of an electrical load as the batteries were fully charged and the A/C was only drawing about 300 watts. Right now, it 86°F outside, the A/C, refrigerator, and converter have been running all day and the Multiplus is set to no more than 12amps from shore power as it’s just plugged into a convenience outlet on the class A. 

Yesterday, I made one of my furthest contacts on the radio using FT8, a digital mode with computer to computer communication through the radio. Over 8000 miles to Saudi Arabia. I was just running this sort of on the side during a long test session. 

This afternoon, I spent a little time cleaning up the wiring on the class C dash for all of the accessories. GPS, dash cam, TPMS, rear camera display, and the Magmount phone charger. I just used some plastic clips stuck to the dash. Mostly because I move the dash cam back and forth to the Jeep. I wanted the cable to be easily removed. 

Class C Electrical Changes

Saturday - I made a few changes to the electrical system on the class C. I changed the absorption voltage from 14.6V to 14.4V on all three lithium chargers, the Multiplus, the Orion, and the solar. The battery manufacturers, SOK, really doesn’t provide much information to configure these devices so it’s left to the installer to come up with something based on their published battery specifications. Originally, I used the high voltage cut off by the BMS of 14.6V. This was a change that I had made on the class A a few weeks ago.

The other change was reconnecting all of the 12V loads in the RV back to the original AGM battery. This battery will be charged by the stock converter which is powered by 110VAC. Wherever that voltage happens to be coming from. Shore power, generator, or the Multiplus (from the lithium batteries). The change was accomplished by moving two cable. The one feeding the fuse panel and the two one from the converter.

My reason for the change is to eliminate the led lights flickering whenever the lithium batteries are fully charged. The BMS will disconnect the cells for a few milliseconds then reconnect. I just found the flickering kind of annoying. There is some inefficiency added due to the conversion from 12VDC to 110VAC then back to 12VDC. A benefit is that the AGM battery will be always charged. The AGM battery is used to start and run the generator. Having it charged is a good thing. 

I also filled the built-in propane tank as well as the gas tank. Over $100 for half a tank of gas!
