0:35 Lab Updates and OS Challenges: Aaron updated his lab to Ubuntu 22.04 to resolve compiler issues and improve compatibility with tools like GTKwave.
0:49 OpenCPI and ZC706: Aaron is developing an OpenCPI board support package for the ZC706, aiming to enable a receiver on a B your FPGA.
1:25 JESD204 Interface: Aaron plans to work on the JESD204 interface for the AD9371 within OpenCPI.
1:46 Opulent Voice Implementation: Aaron is debugging his C implementation of Opulent Voice, currently achieving a bit error rate of 0.1%. He suspects the issue might be related to OpenCPI rather than the algorithm itself.
3:22 CW Proficiency: Aaron aims to become proficient in CW (Morse code) for ham radio.
7:49 Petalinux vs. Yocto: The team discussed the potential shift from Petalinux to Yocto, with Aaron confirming that Yocto is already used under the hood in Petalinux.
10:32 IQ Power Measurement: Matthew implemented an IQ power measurement block using an exponential moving average filter, achieving good results in simulations.
11:44 DSP Multiplier Limitations: Matthew discussed the limitations of DSP multipliers (25 by 18 resolution) and the potential for using shifters to increase resolution.
13:02 Pluto to Pluto Testing: Matthew plans to test the modem with a Pluto to Pluto connection.
13:18 Software MSK: Matthew is considering using a software MSK for transmission or reception via a hack RF.
13:25 Yardstick One Interoperability: Matthew suggested potentially broadening the scope of the MSK modem by interoperating with the Yardstick One.
14:18 HDL and EDA Applications: Matthew is surveying papers related to HDL and EDA applications, particularly code generation and analog design, for potential practical applications.
17:49 Power Measurement in Modem: Matthew highlighted the value of a precise power measurement within the modem itself for controlling ADC loading and AGC.
20:36 General Instrumentation Block: The power measurement block can serve as a useful general instrumentation block and can be a standalone component.
26:04 Ken's Update: Ken is becoming more proficient with Git and aims to document his work with the Polyphase filter.
28:07 Antenna Characterization and Pulsar Detection: Rick discussed the Deep Space Society's work on antenna characterization and detecting pulsars/magnetars using new frequencies.
28:32 Earth-Venus-Earth Bounce: Rick mentioned the upcoming Earth-Venus-Earth bounce attempt, involving a kilowatt at 1296 into a 60-foot dish.
30:16 High Power at Higher Frequencies: Rick highlighted the challenge of finding high power at higher frequencies for the Earth-Venus-Earth bounce, suggesting they might need to build it themselves.
