  1. This was Friday the 13th at Pop's using the Buddipole 20meter vertical.
  2. We meet at Rose State College off SE 15th Street in Midwest city. The meeting is on Rm 200 of the Business Building. Enter from the West side of the building. We also do VE testing at 0900.

  5. I have decided Amy and I are not going so we have 2 tickets if anyone would like them. FREE
  6. This is Net Control for the Memorial Marathon at the EARS Club station in Edmond. Pictured is KM5GZ (Bob), WD5G (Dave) and KG5FBN (Richard). Thanks EARS and Bob for allowing us to have the Marathon Net Control at your station.

  9. 2019 Skywarn Storm Spotter Training Meteorologists from the National Weather Service in Norman conduct storm spotter training sessions each year to help prepare spotters for the upcoming severe weather season. The NWS conducts the training at the invitation of local emergency management officials who organize the training and who, in most cases are responsible for maintaining their local storm spotter network. If you're interested in being a spotter and are looking for more training materials, visit our "Becoming a Spotter" page - http://www.weather.gov/oun/skywarn-spotter. You can also find training materials on our YouTube channel - http://www.youtube.com/playlist?list=PLhzMIjoK81fGyAj0gvvZYRjVHEJ9JNJne

  16. I just recently bought a TEVO Tarantula 3D printer. Should be here on Tuesday the 11th. Will post images and stuff here as I go through the process of learning.
  17. I just bought this radio kit. The main board comes pre-assembled. You just have to wire the controls. Technical Specifications The µBITX is an understandable radio and, hence, can also be a learning experience. The complexity is kept to a minimum so you can always repair and make changes if you so desire. The µBITX has a carefully thought-out operator interface. The tuning knob features many menu options available with a simple push on the tuning knob. From RIT, to dual VFOs, to the keyer, and many other features are all accessible from the tuning knob by simply pushing on it. There are intelligent defaults everywhere (these are easily overridden). Example : below 10 MHz, it auto-selects LSB and vice versa. To operate CW, you just press the morse key. Architecture The µBITX uses upconversion to the first IF of 45 MHz. This eliminates the need for a large number of band pass filters, keeping the design simple and virtually image free. The roofing filter at 45 MHz is 15 KHz wide. The signal is then down-converted to 12 MHz where a low ripple SSB filter with 8 crystals is used to provide a sparkling audio. The transmitter has push-pull PA using two IRF510s for a clean output. The low cost IRF510s are simple and inexpensive to replace should the need ever arise. Receiver : Sensitivity: a 0.2uv signal is clearly audible Selectivity: 2.4 KHz, low ripple SSB filter with 8 crystals RIT (Receiver Incremental Tuning) Continuous coverage from 500 KHz to 30 MHz Sideband selection Detent-less encoder tuning. Tunes with larger step rates when tuned quickly Transmitter More than 10 watts up to 10 MHz, 7 watts up to 21 MHz, 2 watts on 28 MHz CW transmit with the built-in keyer Uses IRF510s x 2 as PA and 2N3904 x 4 drivers in push-pull mode for low distortion transmission. Raduino Features The Raduino is a small board with an Si5351 clock generator, an Arduino Nano and a 16×2 LCD display. It plugs into the main radio board. The software that controls the radio is written in Arduino’s C langauge. The feature set of the µBITX is controlled by the Raduino’s Open Source software. Open Source allows you to further enhance the software if you choose to do so. The menus are accessible by pushing the button on the tuning encoder. You can add more features by modifying the Open Source code. Dual VFOs RIT Manual override of LSB/USB selection CW Keyer Speed and tone selection Can I build it? Boxing it. You can pack the µBITX in anything from a cookie box to custom-made 19 inch rack. A metal box is highly recommended. We have used it every way including the bareboard on the bench. Some soldering is required. The kit is easily put-together. You have to mount the board inside an enclosure of your choice, screw in the connectors and solder the wired connectors to the sockets and controls. That’s all. All SMD’s and other components are pre-soldered on the PCB at the factory. Take a few hours to wire it up. Preparing the enclosure will take most of your time. You will need basic kit-building tools like soldering iron, a VOM. etc. Set aside a few hours to wire it all up and enjoy the experience. Support is here. Being an Open Source project, support is provided through a very active builders’ community at http://groups.io/g/bitx20. The collective wisdom of thousands of builders is at your disposal. Ashhar Farhan, the designer of µBITX is very active on the group. What’s included A fully test and tuned µBITX HF transceiver board (6″ by 5-1/2″). The Raduino board with display with µBITX firmware installed. Detent-free tuning encoder with push button for menu access 3 audio sockets for the mic, earphones, and keyer A high quality BNC Antenna connector Power supply connector and jack 8 brass standoffs with nuts and bolts for mounting the board(s). Reverse protection diode, some resistors for CW keyer. Electret mic and a miniature push button for Push-toTalk Volume control with on/off switch You will have to supply your own enclosure, power supply, microphone case, speaker to complete the radio. I will continue to post through the build.
  18. Dave and I manned the Elecraft booth for Elecraft during at HH 2014.
  19. This is an image of the 147.21 and 443.275 repeaters. The bottom is the Bridgecom 147.21 and the top is the Yeasu 443.275. The black box at the top left is the duplexer for the 443.275 repeater.
  20. These images were taken in 2016.

    What is SET

    I don't know Kyle, SET is an ARES thing. Maybe we can get Tom to answer that question.
