@ryzerth Let's just say the waterfall sink in GR is far from pretty

Just finished the SDR++ Network Source. With it you can trivially import baseband live from any software that can output IQ to network. For this demo, I use #GNUradio to generate a FM signal and send it over TCP to SDR++. It is now available in the latest nightly. #sdr #sdrpp

@F5OEOEvariste That's awesome. I hate how the mighty transceiver is limited by the interface bandwidth. That's the worst thing about Pluto (well, and harmonics, but that could be a benefit).

@Sq3Swf Yes CS8 = Complex Signed 8 bit. This conversion is done on fpga in order to achieve high bitrate which is not possible with arm implementation.

Progress with new firmware (not datv). Get samplerate of 11M/s through usb using CS8 mode without drop. At same time, free web spectrum thanks to maia-sdr. Investigate with DC offset. Lot of #plutosdr features to come. Stay tuned.

@ryzerth @LeoBodnar Right. "B" in LNB convinced me to believe it was indeed a cheap and readily available "block" ;-)

@Sq3Swf @LeoBodnar Will be a custom design most likely

More gear acquired for the satellite ground station project. This @LeoBodnar LBE-1421 should serve as a perfect reference clock for both the SDR and the X band LNB. It will be backed up by a Rubidium reference through a jitter cleaner to get even better phase noise specs.

@Croatia_uW Good luck! :-)

Hope to hear you in the IARU 2024 VHF contest. Look for us 144.320 MHz.

"Hi honey, how are the preparations for IARU VHF?" Me:

@wgoodf Not me, but I believe it was about 50-60 W with 100% duty, aka "ft8".

ATU-100 released the magic smoke. Nice conductive (carbonized) layer on top of good ol' FR4. #hamradio

@ibelings The bad thing is, it does not scale as easily as it is to add more antennas

@Sq3Swf for this test just a 1:4 splitter

The satcom amplifier is doing 250W at 432 MHz with modified LPF. Next step to see if 2x2 phased array can handle the power. #EME

SM4IVE via The Aurora. Strong enough for /p copy. 59A!

@wgoodf Nothing modest about #1 :-)

Found my old portable yagi for VHF. Life is just so much easier when you have a 3d printer.
