 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.

This is the configuration I used to get FLRig working with the Xiegu G90  Digirig cat plugged into radio head communications port. Digirig audio plugged into radio ACC port. COM Port in Device Manager is COM3 - Silicon Labs CP210x USB to UART.  Using FLRig 2.0.0.5, select Xiegu G90 Goto Settings under config Select Xcvr Tab: COM port for USB/UART (COM3 from above) Port Speed 19200 2 Stop Bits No RTS/CTS All RTS and CTS options deselected On PTT-Generic Tab: PTT CAT set to Both RTS and CTS set to OFF PTT control on Separate Serial Port set to NONE

 I want to use remote control with my 7300. This is more an experiment than an actual plan to use my 7300 from a remote location. What I am thinking is that I will use the 7300 remote control port along with a separate audio connection so I don’t have to play with virtual devices to connect the audio for digital modes. Not sure how this will work yet. It’s possible that it is not possible to do this. This is the device I want to build. A USB to Serial adapter that connects to the remote control port of the 7300. The remote control port uses a 3.5mm audio connector with the TIP going to UART TX and RX pins and the ground connecting to the UART GND pin. The TX and RX pins are pulled high through a 10K resistor connected to 5 volts. The TIP is connected directly to the RX pin and to the TX pin via a 1n4148 diode. The first step is to unlink the CV-I remote port from the USB data port. Second step is to build a remote control cable serial cable. I happen to have a cable with a 3.5mm stereo

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
