ALC settings for Xiegu G90

-

 I use FT8 and there has been discussion about what ALC settings are best when using this mode with the G90. I found recommendations in groups.io on the Xiegu G90 group that says after 1.78b, the ALC settings reversed and now 100% means zero (0) input whereas 0% means max volume. The video shows this. I have found the output to be good if the ALC is between 20% and 80%. The video below attempts to show the relationship between volume and ALC.

 I’ve started looking into battery charger repairs for some of my baofeng chargers. I tried to buy a charger for my DM 1801 DMR radio, but the ones they shipped me did not work. They would charge, but were unable to detect when the battery level falls. A working charger using the hc5812 chip will flash quickly between red and green. A defective charger flashes slowly. The hc5812 looks similar to a tp4056, only it handles 8 volts, enough to charge two cells providing 7.4 volts. The newer chargers use a HXN-TWS chip that is very similar to an sc6038. I am currently breadboarding a charger so I needed to get the HXN-TWS onto a breadboard. As it is a SMD chip, I bought 10 adapter chips for .89 from AliExpress.  This is the end result. I use 60/40 solder for the mounting pins and 138°C solder paste for the SMD. I have had good luck with this technique and use a hot air station at 180°C to solder the SMD. Shown is a completed chip, a blank adapter board, an SMD chip, and the 2.54mm breadboar

CQRlog sharing

 I use CQRLOG for my logging program. When I first started back on ham-radio I was using Linux for everything. CQRLOG was the perfect solution because of its low price and high functionality. Eventually I move to Windows 11 and started running CQRLOG in WSL. The challenge now is that I have multiple computers and I want them to share logging. The problem with CQRLOG, is that it is monolithic. Not GUI / API architecture. One option is to run a share SQL server, but I don’t know if CQRLOG would operate using a share database. It might make assumptions that nothing will change without the front end knowing about it first. I haven’t looked into this yet, but I plan to get the source and start poking around. I will have more once I do this. Meanwhile, I am setting up a database running on windows and will try to point CQRLOG at the database.

I have a couple of computers that I use for various purposes. One is my general computer for office and financial work. The others are various laptops that I either bought or acquired. Almost all my computers, including the ones for my wife and daughter, have i7 processors. My argument is that more CPU power means the likelihood of extending the lifetime of the computer. The computer below changed my thinking. I have a Dell Inspiron 1545 that I bought my mother in-law in 2010 or so. It has 3 GB of memory and a 128GB disc drive and an icore duo processor. I use it for packet radio running direwolf and BPQ32. I also have wine and VARA installed. Its amazing how well it works. After the last lubuntu upgrade, the express card with two USB 3.0 ports stopped working, or so I thought. I quickly looked around for a replacement focusing on the low end of the market. I ordered the PC below, a super compact N100 12th generation processor. With 512 GB disc and 16 GB of DDR4 memory from AliExpress
