I would look at the desktop shortcut path and see why it's showing two different radios. You may need to do some editing to make the radio discovery show only the listed connection by the Start button.

Most likely is because you are not running the latest version of PiHPSDR. I ran into the same thing and had to download and build the latest version to get it to work.

Glad to hear you got it figured out.

Maybe you fixed the problem when you reconnected the pins. I seem to recall reading that there could be issues using the front panel controls to control Thetis on the pc. I don't know if that has been updated to not be an issue anymore.

I updated the FPGA in my Ultra just yesterday from Laurence's Github page.
No issues with the front panel display. Maybe a setting that your friend was using previously has changed?

I use a stereo splitter cable with female RCA connectors on each side of the split. That way I have PTT in for my handheld PTT switch and the other for PTT output to Key an amplifier.
Here's the wiring diagram from the manual showing how wire the stereo plug if you are only interested in using one ...

I just tested this with my Ultra. Using the rear TRS connector for my microphone and a separate PTT switch, I don't notice any delay going from transmit to receive when I release the PTT button.
Which microphone are you using? Are you using the front panel microphone connection? It could be the PTT ...

Scott, the G1 doesn't come with a front panel. Just the G2 series.

And, as you can see here, VAC is not selected.

Windows 11 should look like this using a USB audio interface.

If you loose audio with VAC unchecked, then you have a settings issue. If you have edited the Registry with the correct entry for your interface and in Windows Sound settings, you have selected the USB interface for Audio input and output, it should work. VAC is not needed for cmASIO to work.
In ...

Are you using VAC to connect to other software? If not, I would suggest leaving it unchecked. cmASIO with your Foucsrite is all you need unless you are also using software like FT8.

20251002_211400.jpg I actually have it working on an old AMD mini desktop. Using the latest version of PiHPSDR. It took a while to download everything and build. Plus, about half an hour creating the Wisdom file. The original PiHPSDR was designed to run on small displays. Christoph allows you to ...

Thanks James,

do you know where - i am in Europe?

Best regards,
Boni, S50BN


Unfortunately, I don't know who handles service and repair for Apache labs in Europe. There may be a link on their website to someone or a dealer in Europe who can help you. Otherwise, you will most likely have to fix ...

From your description of the problem it sounds to me like a hardware problem. Possibly the encoder is causing this. You may need to contact Apache Labs to get it resolved.

Just don't add to much echo and reverb!!!

But, would the CM4 Pi have enough horsepower to run it along with PiHPSDR?

Being that Apache labs doesn't actually provide software support other than pre-installing the firmware and operating system for the G2 radios you are now experiencing what some people would consider the downside of using radios that depend on open source software and developers.
As Scott has ...

Noise reduction 2 in Thetis has some settings you can change that will improve how well it works. You may need to experiment with them a bit to find what works best in your location.

Scratch my comments about not using Voicemeeter Potato's ASIO driver. ( it's getting late) I think you have a problem with a Voicemeeter Potato setting somewhere. Especially if everything works correctly when you use just the Personus ASIO driver. Hopefully, someone more experienced with Voicemeeter ...

Having only tested Potato a few times myself, I would think that you would still be able to route your audio to Voicemeeter Potato and still continue to use the Personus ASIO driver. And that you wouldn't have to use Voicemeeter's virtual ASIO driver.
I could be wrong about that. But, I think I have ...

I just checked my G2 Saturn Ultra and it puts out a solid 100 watts on all bands into a dummy load. It was like this from the factory. Open the menu in PiHPSDR and select Transmit. Be sure that the checkbox Tune use Drive is selected. Also Tune drive level is set to 100.
I think you will find that ...

Does it do it if you disable the connection to Potato and just route the audio through the Windows System/Sound settings? That might reveal if the problem is with settings in Potato or how you have setup your cmASIO driver in the Registry.

That is odd. Is it noticeable if you have noise reduction turned on?

Sounds like you are going to have quite a challenge. I have not looked at the latest source code. But, I don't think that the different control groups are in containers where you can resize them or move them. If you haven't already done so, you might want to connect to Richie's Discord page. You ...

I am not where I can look. But, there is a setting where you can hide several of the different legacy button groups. Then, you can place your customized buttons wherever you want.

Setup/Appearance/Legacy Items.

The Intel Cyclone 10 LP FPGA is a current product available from several sources. So, for the time being, it shouldn't be a problem sourcing them. Mouser currently stocks them.

No,there isn't a Raspberry Pi CM4 module in it. It is like Scott said, it's more like a 100 ( single ADC ...

https://apache-labs.com/products/ham-radio-products All products still on the website...

They changed the website again. The 1.5K transceiver and amplifier were not listed anywhere on the website last night. Who knows, maybe they will come through for those that put deposits on the radio and ...

Reading the specifications for the radio it is more like a 7000 MKII . No Raspberry Pi CM4 module so, it will have to do like the older models and emulate the Ethernet Protocol in the FPGA. Since it only mentions one ADC, it won't do Diversity Reception. It's more of a lower priced, single ADC 7000 ...

Just a few days ago you could click on Products and it would take you to a page showing the 1.5K G2 and the amplifier. It stated that they were not taking orders at this time. Now, all of that is gone. The entire website has been revamped and only the G2 Saturn Ultra and the G2 plain face radio ...
