Re: Thetis and TRX-Duo works
What about PureSignal? Does Pavel's image do the DAC copy business that PS depends on? Yes, PS works great with Pavel's code on the Red Pitaya. Take, JA5AEA, made some modifications which allow a step attenuator to be automatically controlled by Thetis on your feedback signal. More info: https://gr...

Re: Thetis v2.8.11 - current issues
Thanks to all for the spectacular work here. I have one thing to report: Playing with 21k6 here and noticed that the "signal history" shaded area on the meter is gone. I checked that it's ticked in General and has a color and an alpha configured in Appearance->Meter. I'm not sure when thi...

Re: Coupler Solutions
Thanks, Mark. Well 18k/50 would give you -51dB so seems sensible. I put a shunt 50 on mine so whatever driving point impedance the PE4302 step attenuator presents is in parallel. Probably 50 ohms so maybe another -3dB. I don't think it really matters anyway. Mine seems very linear. I think they are ...

Re: Diversity Operations
Newcomer to the forums here so pardon the resurrection of old threads... As I've told Scott before, I've found the diversity/beamforming to be incredible. My RX1 is a big skywire loop (700ft+) and my RX 2 is an amplified 1-meter "mag loop". Almost always if there is a local interferer I ca...

Re: Coupler Solutions
Thanks, Rob. I found your information and videos about configuring the audio chain in PowerSDR/Thetis to be quite valuable and well-presented. While I kind of "winged it" on the CFC EQs, I routinely receive unsolicited praise for my audio and signal! I started perusing the forum to find ou...

Re: Coupler Solutions
Greetings, gentlemen. I've been reading the forum and enjoying the wealth of knowledge and expertise here. I figured I'd share my experiences with PureSignal in hopes that someone might find it useful and/or interesting. Firstly, I'm not using an ANAN. I have a homebrew setup based on the Red Pitaya...
