At some point when I have more room, I would like to have at least one machine clunking away in the corner of the shack. I miss the smell of the old canary yellow paper and oil, and the sound of the machines. Sound: QPSK-250 Spectrum Sound: all signals shown in x2 waterfall mode, tick marks at. My first Ham RTTY contact was on Novemwith WA9HCZ (SK) a local Ham and Elmer.
It can be set so one serial port runs one optocoupler and another serial port can run the second, or, as its wired at the moment, one serial port can run both optocouplers. BPSK-31 Spectrum Sound: BPSK-63 Spectrum Sound: BPSK-125. The audio transformers I used are 20k primary, and a 2k centre tapped secondary. It also contains two optocouplers, one to switch the radio to TX and one for RTTY FSK keying. Both of which are variable inside the interface via two preset resistors.
It contains two isolation transformers, one for AF from the tranciever to the line in on a soundcard, and one from the audio out of the soundcard back to the mic / data input of the radio. The input audio file should have a sampling rate of 8000 Hz and a quantization bit rate of unsigned 8. I hate to be the 'helpless little old lady' after being licensed for 66 years, but I could sure use some help, folks.This was my practical project for the intermediate exam. I also tried the standalone MMTY program with the same problem. original sound - Aki prtty is a popular song by kon kon Create your own TikTok videos with the original sound - Aki prtty song and explore 46K videos. Using the rig's RTTY mode instead, I can decode signals, and I can key the rig, showing power out but only with a constant tone. (No apparent difference.) I think I'm using AFSK vice FSK but don't see where to check, and it shouldn't matter.
The menu RTTY settings are all default except for trying USB instead of REAR. There was an attraction in the sound of the mode for me. The RTTY sounds normal on monitor, but it must be garbled if no one can decode it. Talking to Jim Hepburn, VE7KX, on CW, Bill found that there were several stations active on HF RTTY. I could copy and transmit with power output (300 watts with amplifier). I had my FTDX 3000 on USB with the laptop N1MM program running MMTY Reversed.
Or how to remove the so called ground loop and the reentry in the RTTY broadcast and make radio and PC happily. I suspect the few strong JAs I heard couldn't either. Rtty interface (FSK/AFSK) with sound cards. A friend 10 miles away couldn't decode my call sign.
