We are in the process of changing the firmware, p2app and piHPSDR to work with enlarged FIFO buffers in the FPGA. Debug code has identified that we were stalling the software waiting for a speaker FIFO to empty. Hopefully a combination of enlarged buffers and a different way for the software to tra...

Bob -- that does beg the question, have you tried operating into a dummy load? This would help narrow the RFI problem. If this works then it's probably a conventional, radiated RFI problem. If the dummy load does not work, then it's either a conducted RFI problem or a problem internal to the G2. Hi...

I have never been able to get the XLR 1/4" connector to work. I use mix 31 and have a good ground. I have tried running a ground to the shield of the connector and that didn't make it work either. I have used a Neumann 103 with a tube preamp and also a MXL BCD-1 direct to the XLR jack with the...

I'm using a shielded XLR cable for the MXL BD-1 dynamic studio mic for VAC, and the condenser mic on the front panel TRS input is a D-104 with supplied cable and shielded TRS plug. Both mic cables have multiple ferrites. AudioBox GO is connected to the i7 via usb cable with ferrites.

Hi Scott. Thanks for that information. I have tried using the Presonus alone using the mic XLR input and headphone output and that seems to work normally with clean and full audio. The only software I'm using for the Presonus is the Asio drivers for the Win 11 I/O. I agree that this sounds like an R...

I'm using Thetis.

Thanks Scott. I appreciate your input. -- Bob - Ki1n I have made numerous attempts to use a balanced input dynamic mic using VAC and a Presonus Audiobox GO, but cannot raise the input level without causing some type of "runaway" screeching or oscillation. I can only achieve about 5 watts ...

@laurence: tnx for background info! Using the Armbian environment made an image on basis of arm64 architecture and kernel 6.5, but with just enough in the OS to let pihpsdr show its GUI. So basically just cli plus X11 and Openbox Have patched 'your' xdma driver into it and for now called it xdma2 a...

Thanks Scott. I appreciate your input.

Good morning Scott.
Understood, thanks. I suppose another workaround might be to employ audio input hardware or software to the PC and use VAC, right?
-- Bob - Ki1n

Hi Scott.
Thank you for that valuable information. That certainly helps address my confusion!
Have you any thoughts on when and if Apache might address the balanced input issue?
-- Bob - Ki1n

Thanks James.
I did just update the firmware, but I'll go check to see if there is anything newer.

I am hoping for suggestions on how to address the following issues with my New G2 with front display. • Using PTT to key up on LSB, others have noticed an initial carrier that diminishes gradually during the first 2-3 seconds of each transmission. The dynamic MXL DB-1 mic is connected to the front p...

Bob, Are you using Thetis or PiHPSDR at these sampling rates? there is no issue whatsoever running Thetis at any sampling rate. If you are getting artifacts on Thetis it is most likely a localized network/PC issue. Tony Hi Tony. Thanks for your note. Yes, I am running Thetis v2.10.1 on an i7 NUC 4....

Jim, What sampling rate are you using? I would suggest 48KHz to see if that helps. Tony Thanks Bob. I also upgraded the Pi and P2 and it is still not right. Tony says they are working on it but it has been a while since anything has been said as to whether or not they are making progress. 73, Jim K...

Thanks Bob. I also upgraded the Pi and P2 and it is still not right. Tony says they are working on it but it has been a while since anything has been said as to whether or not they are making progress. 73, Jim K6JR Well, obviously these new units are a work in progress. That's ok but I sure look fo...

Well it has been 2 months that I have had the G2 with display and bad receive audio. Support, Tony and Doug are aware of the problem but I have heard nothing in regards to fixing it. The sounds of crickets on here also. I'm about to ask for a refund. I'll continue to use my other Anans that work co...

The codec is connected to the FPGA; it receives (and generates) samples at 48KHz synchronously to the ADC & DAC. Audio samples are transferred via the Raspberry pi, but it is not interfaced to the operating system so you cannot send WAV files to it. That's why you see no audio device listed. Wh...

Rob,I received an email from another G2 Saturn owner with the front panel today and he told me that Apache labs, either through Doug or another person, is sending him a new SD card for his radio that should solve the audio problem you and others are experiencing. I would suggest you contact Doug to...

I have been dealing with stuttering and breakup issues since receiving the G2 and using Thetis 2.10.1 with an i7NUC directly connected to the Anan. I've throttled down speed to 192,000 and that helps reduce load but does not completely fix the problem. I've heard others are also experiencing similar...

On a G2 using Thetis Ps, I’m getting intermittent audio breakup on SSB that does not seem related to mics or connections. Any thoughts on settings that might cause this behavior? Some transmissions are fine, but then drop outs return on next xmit. I just checked Network throttling Index in Thetis bu...

FYI, I was told by Anan that the G2 has the front mike input wiring reversed with Tip audio ground and ring mic input. Rear mic plug is wired normally with tip mic input and ring audio ground. XLR is inoperative. Once I abandoned trying to use the XLR inputs I was able to wire and profile mics for e...

Great, thanks. I'm experiencing intermittent drop outs during transmissions with a G2 and an I7 NUC, so will give this a try today. -- Bob - Ki1n

Could this also help with Win11 and Thetis Protocol 2 running Anan G2?
-- Bob - Ki1n

I get reports of the G2 transmission dropping signal at the beginning or during transmissions using Thetis Protocol 2. I can sometimes see these events on the screen, especially when tuning on AM. Power keys up, drops by about half and almost immediately recovers. This happens when the G2 is connect...

Upon further discussion with Bill Diaz and retracing all possible connections, I found that the Heil headset required the PTT switch to be connected in the TRS breakout adapter to apparently provide a ground path for the audio. Here is the breakthrough—using the PTT switch solved the problem. Appare...

Could someone please help me figure out the following issue with my G2 w/front panel screen. I have a headset with mic that uses a 3.5mm mono plug. Plugged into the front panel no audio with the TR plug and no audio with a breakout TRS plug in which the TR plug is inserted in the ring socket. Using ...

Thanks for those very helpful tips! -- Bob - Ki1n

Exploring the PTT IN/OUT further, I remain confused about the wiring to the amp. The PTT OUT takes TIP to Ground on Xmit, and provides 8vdc on RX. The RING is taken to GROUND on both RX and TX. This is using PTT on the front panel mic input. Any thoughts on how I can access a PTT OUT that is OPEN on...
