GPS disciplined 10MHz oscillator (GPSDO)
Excellent design by Paulv on his web site I have PCB v4.2 available on my shop if your interested (contact me for details) Also shown my design for a distribution amplifier with 1, 5 and 10MHz outputs (PCB Also available)
Double Double Mag Loop Antenna
3D printed parts instead of PVC, High voltage Air Variable Capacitor Tested to 200W.
Rated at 100W CW or Digital Modes 3’ Diameter About 30lbs
20M, 30M, 40m SWR < 1.2 on all bands Stepper Motor remote control.
T41 SDT (software defined transceiver)
The T41-EP (Teensy 4.1 as an Experimenters Platform) is an HF 7 band, 20W, CW (Morse code) and SSB (voice) transceiver. All of the processing is done by a single Teensy 4.1 without any other processor or external PC, laptop, or tablet that most SDTs require. The entire project is Open Source.
