Hi Hidehiko,

thanks for the report,

this is an Avalonia error that seems to pop up every now and again System.InvalidOperationException: Default font family name can't be null or empty · Issue #4427 · AvaloniaUI/Avalonia (github.com), you could try sudo apt-get install ttf-mscorefonts-installer as that has fixed it for some other Avalonia apps.

If that does not work, let me know and I'll dig deeper.

Hi,

OK

I'll try to release a new version next week with the fix mentioned in the Avalonia issue.

Hello Alan,

I bought Raspberry Pi4B (4GB-RAM) and install SparkSDR from .deb file for Raspberry Pi.

It's installation is OK but after I ran it then the similar error message appears as follows.

In my situation only the Windows10 is OK and it works very well, 5 or 6 virtual receiver can be heard individually at the same time.

It's just for your information.

73, Hidehiko JA9MAT.

Alan,

I also am looking forward to the updated MACOS version.

From what I can tell,

the latest MACOS preview is 2.0.7.9

the latest WIN64 preview is 2.0.8.6

the latest ARM(rPi) preview is 2.0.7.4

and next week the Linux version is what you are intending to update.

If I remember right, you were doing a rewrite of some complex code.

But I am confused as to which version have which features.

I have a cluster of 5 raspberry Pi4 8Meg Ram single board computers that I would try to run SPARKSDR and see if more processing power increases the ability to process more slices of amateur radio. For some reason, my original hardware using my HL2b9 transceivers would not rank very high on the spot reporting. Did some RF antenna upgrading. Then moved to upgrading from from an I5 to a I7 improved things, so I thought I would try a cluster of 20 raspberry PI cores. As time permits I will see if the ARM version of SPARKSDR on a cluster runs better than my I5 or I7.

Beyond the confusion, is being THANKFUL for your AWESOME contribution to the hobby.

SDRadio would not be the same without your product.

Hello Alan,

I've been studying about my issue and I found the way to run SparkSDR correctly. I changed locale from Japanese to en(English), GB(UK), UTF-8 then the SparkSDR boots with using both Ubuntu20.04LTS and RaspberryPI-4B. My issue may be caused by 2 bytes character code? Anyway I'm listening 8 separate frequency using RPi-4B.

Thanks a lot for your nice program!

73 and have a nice weekend, HIdehiko JA9MAT

Hi HIdehiko ,

good to hear you found a workaround. There is a test version here https://www.sparksdr.com/download/SparkSDR.2.0.8-8.linux-x64.deb which hopefully fixes your problem, please let me know if it works.

Hi Alan,

Thanks a lot for your support.

It works well at my Japanese locale.

And some addition are very good.

Auto Reply, Auto Seq. and Operating and History Views are very useful.

I think the load is lighter than before.

I'm sorry but I have a request to decode the OPERA-32 digital mode in the future. It's good for 2200m band propagation.

73, Hidehiko JA9MAT
