- I was going to hang up my soldering iron for the summer but with friends like ZL1BPU a boy like me will get no rest. Why only 5 tones he insisted, well I took a short cut I used another bit to enable/disable the original 2 bits of WSPR, when the 4 Units were high impedance I set another tone frequency. I then squeezed S/MT Hellschriber into 5... more

- Don't worry, be happy. Precision timing is in the eye of the beholder. This is a MANNED Experimental Propagation Transmitter after all. The dirty finger is deliberate,it was actually dirtier in real life. more

- Manned Experimental Propagation Transmitter for Manned Experimental Propagation Tests. A new MEPT band, for me 160 meters. I could build the same tried and tested design for all bands but the fun is in the experimenting. This Transmitter uses only 2 Transistors. NPN Crystal Oscillator DC coupled to a PNP Output Amplifier an ideal use for the old... more

- Joe Taylor and Murry Greenman have been working on a new mode MEPT_JT. Just released this software produces and receives a 4 bit data stream with a total bandwidth of just over 6Hz. I got it up and running yesterday morning on 10Mhz, output 100mW to a 6m CB whip with Radials and ATU Output power 100mW. Here are the reports all in daylight... more
