Tell him to send me his mashup songs. Maybe he still has access from the far east.
I was testing a new high density DSP with dynamics that was not easy to achieve that I been working on for a week.
If I go that way I would do independent sideband stereo sound with images on both sides.

How about some mashups like The Relay Station used to play?

I was finding a clear frequency out to Europe and Australia.
Thanks for tuning in tonight on the 31 meter broadcast band.

The added image was not part of MRI’s waterfall. It was from another stations signal running along side.
Thank you for all your posts, email’s, comments, and listening to our station as always.

North American Shortwave Pirate / Re: Mix Radio International 6845<6855<6880 USB 0117 UTC 4 SEP 2023
« on: September 04, 2023, 0323 UTC »This was a waterfall image test to see the viability of playing music with the bandwidth lowpass filter set and at the same time being able to send images from above the lowpass cutoff frequency.
Thanks for picking them up.
OK. Here's another idea: images on the LSB and simultaneous music on the USB.
If I go that way I would do independent sideband stereo sound with images on both sides.

Equipment / Re: New to me R75
« on: August 11, 2023, 0502 UTC »
I run power SDR interfaced with IF stage and CAT control functions on a modified HF transceiver. I can use the VFO knob to tune with tracking.
I also have the R75 that developed audio distortion. I traced it down in the -5 volt power supply circuit that uses a 555 IC as a DC to DC converter to a bad capacitor causing a low output voltage.

SDR - Software Defined Radio / Re: KiwiSDR future/replacement?
« on: July 15, 2023, 0058 UTC »
Nice. I am glad you tried it. I mostly listen to my transmitter in IQ mode. I find it sounds better because in sideband the kiwi has preemphasis. It is not needed on my transmitter since I run preemphasis.

SDR - Software Defined Radio / Re: KiwiSDR future/replacement?
« on: July 14, 2023, 2322 UTC »
With my transmitter bandwidth down to 10Hz I can hear a non GPS frequency locked kiwi off by a few hertz when monitoring my station and use headphones that have a very good low end responsive. Even without a wide bandwidth transmitter If you listen in IQ mode you can hear the zero beat drift with stereo headphones if not exactly on frequency.

Transmitting in ISB stereo with suppressed carrier is effectively DSB mode. I mostly transmit in sideband anyway. I may get around to working on this at some point.

I use 1Hz resolution adjustment when the kiwi or receiving station is off frequency. You just enter the 1Hz digit as a user. The digit will not show up in the display but will change.
