Posted - 03/03/2023 : 16:32:49 Please see image. I am astonished to have received the GQ Tool-081 Audio to USB data cable in such a manner. I realize that an improvement was made, in now having a connector at the board rather than being hard wired but really, could not a bit longer piece of heat shrink have been used? The exposed solder board connections in this are unacceptable. GQ electronics can you please resolve this?
Support said they are already resolving this issue.
Thanks EmfDev! I’m standing by for the resolution. Bob

In this forum I see no way to attach a file to a post (apart from image files). But you are always welcome to make a post at the GeigerLog Discussion site (https://sourceforge.net/p/geigerlog/discussion/) and add as many files as you like. You don't have to register at SouceForge (but then your post would go into moderation first).
The Mac has no sound input? I am surprised.
I don't think there is a Geiger-clicks specific conversion in the GQ adapter; I expect a plain USB-Soundcard. You can verify by playing from this adapter to the computer's speaker.
So you not only have antique Fiestaware, but the matching Geiger counters as well ;-)
At first glance the DP-66M data seem ok. As this is such a nice old counter, I'd like to take a closer look, and - if you are ok with it - put the data under my example selection and perhaps distribute them with GeigerLog. Perhaps you can post the data on my discussion site?
When I look at Geiger data, first step is visual impression. Then click Moving Average, and LinFit, and look again. However, crucial is the Poisson test. Find some brief info in the GL manual, chapter "Poiss – Histogram with Poisson Fit" and a bit more in the "Potty Training" article.
Do you have an oscilloscope and could post pictures of how the pulses look like?
Thanks for the information. I posted the data at Sourceforge under the topic: "GeigerLog User data Submittal". You have permission for use as you described. Unfortunately I have no oscilloscope.

Posted - 03/05/2023 : 21:24:55 On my desktop I do have a Mic and Line in so I hooked up the DP66M to the PC Mic input using an audio cable as you suggested and got the following readings with the beta widow open measuring mostly the background in my home. The higher CPM's were from a piece of Fiestaware I had on the probe LOL! Apologize for the long running text. Is there no way to have attached the text file?

To be a bit more serious: what do you want the audio connection for?
All desk- and laptops today have a sound input. I tried several, and they all work with audio output from multiple Geiger counter sources, including the GMC counters.
The one computer exception is the Raspi, because it has no native sound input. For it I tried multiple so-called "USB-Soundcards" and they all worked. My preference is this one for half the price of the GQ fiddle-ware: https://www.amazon.de/gp/product/B07RS11PDD, but even cheaper ones also worked.
For details see chapter "GeigerLog’s AudioCounter on Raspi4 (Buster)" in the GeigerLog manual (spoiler: the Raspi is overwhelmed with audio processing).
Audio works, but a digital connection - be it by wire or wireless - is a lot more convenient.
Well unfortunately my 2020 MBP i5 only has a Headphone audio output no input so I will need a audio to USB cable so I can connect my Vintage Polish DP-66M this is the primary use I have planned for the cable. I am also assuming that since this is designed for Geiger Counter analog audio "click" to USB input that there is circuitry to interpolate the individual "clicks" or pulses and appropriately/accurately filter and convert them into a digital signal in other words a Analog to digital converter onboard.

Posted - 03/04/2023 : 13:16:45 I emailed order support at GQ Electronics I just received a reply. They said they’re investigating and will get back with me. Sounds like they’re going to take care of it.
