I'm sorry, Tony, I don't see the word "latency" in the release notes, and I didn't see such a setting in the new version. Where did you see that?

Thanks,

Re: Astron RM 35 with 8000

I'm using a Powerwerx SPS-30DM, which is a 30A supply. It has been working fine to run the radio at the power levels required to drive my amplifier (<40W). I can't speak to how that works at 100W, though.

Understanding the (non-VAC) audio paths

The audio paths used in openHPSDR architecture radios, as all the ANAN series radios are, may not be intuitive. It is important to remember that these are software defined radios. That means that, with the noteworthy exception of digital up and down conversion, nearly all radio signal processing fun...

Re: CAT Control in PSDR mRX

Yes, you need a separate serial port pair defined for each connection.

E.g. COM31 to COM32, COM33 to COM34, COM35 to COM36, etc.

There is absolutely nothing special required. They all work exactly the same as the main CAT port assignment.

PowerSDR mRX PS is not "DPI aware". That is to say, all controls and labels are designed to remain a fixed number of pixels in extent. Thus, if you have a display with a high DPI (dots per inch, or pixels per inch if you prefer) scaling, then those controls and labels will look quite small...

Re: Hermes Fail to Start

No suggestions other than to send your board to someone else who has built their own Hermes and who has the required hardware debugging skills to debug it for you. Obviously it will require careful inspection and analysis of the many signals on the board to isolate the problem.

Delete or rename the entire "PowerSDR mRX PS" directory. This will cause PowerSDR to start over from scratch.

Re: VAC SIGNAL NOT STEADY

I will be using VAC for SSB for processing my audio thru VMB and even DAW. I recommend you obtain a good quality sound interface that supports ASIO. This will eliminate any problems with MME or WDM.

Re: VAC SIGNAL NOT STEADY

Just use MME if you can't find buffer settings that work for you with WDM-KS. Low latency is not required for any digital mode except for ARQ modes like WINMOR.

Re: ANAN-7000DLE Update

I would also add that a lot of people are using higher end, amplifier speaker configurations that would benefit from having true line out level signals available. I would venture a guess that there are many more such people than those using the digital inputs.

Re: VAC SIGNAL NOT STEADY

Do you have more than one radio to try this on using the identical setup: same PowerSDR, same PC, same everything (except database)? If so, and if it demonstrates that there is a difference, then this would suggest a corrupt database associated with your 10E setup.
