Introduction of Quansheng's UV-K5 handheld ham radio
- UV-K5's firmware stored in flash memory, allowing rewrites using USB programming cable
A growing community of hams adding software-based improvements and features
Examples of mods include graphical spectrum analyzer, text messaging between K5s, improved AM signal reception, and custom start-up messages
Web-based patcher/flasher allows easy installation of mods without exceeding memory limit
Potential risks of abuse and reliance on ham radio's honor system
Future possibilities of increased in-radio processing capabilities and app-like functions
- The Open Interpreter repository provides a natural language interface for computers.
- It enables users to interact with their computer systems through a chat-like interface in the terminal.
- Open Interpreter supports various programming languages, including Python, Javascript, Shell, and more.
- The repository offers installation instructions, usage examples, and an interactive demo.
- Introduces embeviz - a simple side project for exploring text embeddings
- Uses backend API with GoFiber framework and frontend UI with React and React Router
- Provides interactive charts for visualizing computed projections
- Can label texts and select options for both projections and chunking
- Offers swagger docs for the API, in-memory data store, and persistent data store with QDrant
- GitHub repository for a tutorial series called "0 to LitGPT."
- Provides an overview of how to get started with LitGPT, which is an open-source implementation of GPT-3.
- Offers various resources such as codes, issues, pull requests, actions, security features, insights, and more related to the LitGPT project.

31Here are the two different kinds of capacitors you need from MCM. I just ordered and installed them last week.
31-7190 - CAPACITOR 35V 68UF 105C HIGH TEMP, 105C, RADIAL
31-7215 - CAPACITOR 35V 470UF 105C HI TEMP,RADIAL (10D X 16L MM)
Thermador SC301T and SC302 stack ovens have a weakness in the radial capacitors on the circuit board behind the LED clock. They get cooked from heat. Here is the fix: Remove two screws from the control panel, located facing up at the bottom on the panel frame.. open the oven door to see them. The panel is then held in place by push in toggles at each end, pull towards you to remove. Carefully unplug the three wiring harness plug-ins, and check them to see if any wires are loose. Set the panel aside. Remove 3 screws holding in the LED assembly, and again unplug the wire harnesses, examining each for loose wires at the terminal. When unplugged, take the LED assembly to the bench, remove the plastic housing, and with a mini soldering iron and watchmaker's eyeglasses, or hobby magnifier,
identify, heat, and remove two 35v 450uf 105 degree radial capacitors, and one 35v 68uf 105 degree
capacitor. These are ordered from MCM Electronics (google it) and are p/ns 96K0326 and 96K0331.
Insert new parts, solder and clip excess leads. Carefully examine the printed circuit board around the area of the leads you just soldered, as some boards do not have the copper close enough to the hole to make contact. Scrape the green insulation from the conductor near the hole to expose copper and make sure your solder makes contact with the copper and the lead. Use your multi-tester when finished to check continuity from all leads you just soldered and their nearest neighboring contact on the circuit board. I found a loose wire on the harness to repair, and one contact on a capacitor did not have the copper close enough to make contact without extra effort. When all is completed, reassemble. Turn back on power at the circuit breaker. You may get an F7 error code. Off with the power again, wait 3 minutes. Restore power, go to oven and press the OFF position on the glass control panel... hold for 10 seconds, and the clock should now be steady at 12:00. Push clock position, reset clock for proper time. Test oven light on/off. Test bake/temp/convection buttons,
on/off. This is a good fix, and will save you about $469.00 in parts and $500.00 in labor. The new
105 degree centigrade high temperature radial capacitors replace old 85 degree, which fail, and your repair should last. Total parts and shipping costs.. about $10.00
