Thanks Paul, Scott for you help and tips on this. When I get a bit more time I will dig in a bit further and I will keep you posted. Thank you.

Thanks again Paul. Interesting, they must have made some changes to the component values in later releases for the Mic Preamp board. This schematic is dated April 27 2023. I purchased my G2 in the beginning of April and I guess this is why I see the mismatch with components values on my board to thi...

Thanks Paul. Other variations is see from the schematic and my board is, on the schematic R4 & R5 are 1k5 resistors, and on my board they are both 2k2 resistors which are the audio inputs on the op-amp pins 2 & 3.

From the schematic it looks like I'm missing a R3 and R6 on my board, both are 10k resistors which should be placed across the mic hot and cold pins and pin 4 from J1 header. If you can see from the image there is no place holder for these resistors. I wonder if others that have issue are missing th...

I am going to try and put a 22pf across pins 5 & 8 of the op amp without changing R8 value for now, and see if this improves things.

Hi all,

Laurence, Scott and Paul thanks for looking into this further. R8 on my Mic Preamp board is 10k. I notice R15 which should be 2k2 ohms is bridged on my board - Top left of image. Thanks.

The irony, lets admit nothing but just put a Band-Aid on that input just in case. I've said this from the beginning on this thread, there is an issue here but no one is listening. Instead it must be your mic wiring is wrong.

Hi all, these are my settings with external coupler. SetPk 0.2899. If I select the default button it sets the SetPk 0.6121and pure signal no longer works.

Were they really scammed or is this the sign of a dying company. I hope not.

Its insane to think that a 4000 euro radio can be shipped in this dysfunctional state. There's no excuse for this. Quality control is non-existent it seems.

Hi Roger, Sorry to hear of your issues with the new G2. Have you tried hooking the G2 to Thetis and if so what version of Thetis? Latest should be v2.10.2.2. I too hear a hum with no microphone connected to my G2 when I PTT the rig and I thought this maybe inherent to the issue I am having with poor...

Unless and until you publish what mic cable wiring you used for these tests all bets are off. AFAIK you are the only person having this difficulty and you've already documented an incorrect cable build for the front and rear "standard" mic inputs (not to be confused with the rear balanced...

Hi all, I appreciate the feedback for this issue but I am not closer to resolving by just focusing on mic cables and the like. The issue is solely with the G2. It is unable to provided clean audio amplification when plugging in a Dynamic Microphone into the TRS socket directly or into the standard m...

Thanks Scott. No mic was connected when taking voltage readings. My G2 is the non-display version, so no mic inputs on the front panel. Just on your point where noted that some people have reported that tip and ring are reversed on that rear panel balanced input I will check this out. However, even ...

While there is some anecdotal evidence that the rear balanced mic input is more sensitive to RFI than the front panel unbalanced input, nevertheless 99% of all RFI problems are due to one or more of the following three problem areas: Poor station grounding and bonding practices --example: https://c...

Distortion is the same when transmitting into dummy load also, and gets worse with power increase. I took a few pictures to explain better. With bias disabled on the mic inputs I see a voltage on the mic tip and mic ring terminals which seems kind of weird. Depending on Hardware Options -> Selecting...

Just to add. My microphones are dynamic - RE20 and SM7B.

Hi all, My G2 has developed an issue lately where my TX audio is very distorted when I plug my microphone directly into the TRS or the standard mic input sockets. It actually sounds like rf getting into the audio even though I know this is not due to RFI and I suspect this is something with the radi...

Thanks, I have sent an email to Apache Labs and I did not get a reply, plus I do own a G2 purchased in April.

Hi all, is there a detailed schematic of the Saturn PCB board available somewhere for reference to the Anan G2 radio? Thanks.

Laurence, After the git pull --force command I receive the following error.

Thanks Laurence. The firmware update went smooth here also.

Hi Torrey, I suspect what is happening is the mic tip is acting as ptt ground. I suggest to read the Saturn manual there are some gotchas if you do not accustom yourself with it. You can change this setting in Thetis Settings -> General -> H/W select and under hardware options set Mic to ring instea...

I too have not been able to get the Line-in or Balanced XLR inputs to work on my G2 no screen model running Thetis 2.10.0? The p2app starts by default without arguments. You can auto enable the xlr mic input as I have done by following what is documented in the Saturn manual. However, I found the f...

The newest release of piHPSDR can select the XLR input from a setup form control. Soon Thetis will be able to do the same. I've found why line in isn't working (the code is taking right line in, and it should be left). That will be fixed soon and I'm making audiotest able to show line in signal lev...

Now i get auto color like a red color letters p2app Can you take a screen shot of the console? By the sound of what you are saying I suspect the p2app is running in the background it should have an PID number of the process if this is the case then that app is running. If my assumptions are right, ...
