Disclaimer: I don't have any of that equipment... Looking at the manual for the DU3500AL it looks pretty straightforward. Page 16 shows the connections you need. The manual doesn't provide any detailed pinout information. Thetis supports Kenwood CAT protocol so you'll need to select that. You'll als...

Perhaps a helpful point of clarification: gain is R8/R5 (assumes R5 always equals R4). As an example, the schematic shows R8 = 15000 and R5 = 1500. Therefore the gain is 15000/1500 = 10 (unitless). In decibels this is 20log(15000/1500) = 20dBV. It sure would be great if someone who is having a probl...

Is it known whether PureSignal was used when the 7000 was tested?

This kind of variability in production units is crazy. Laurence's board has R8 per the schematic, you can see it in his photo. This is real quality problem.

I got permission from Abhi to publish the schematic of the Mic preamp board for the G2. Thank you Laurence! I also found that R8 was 10K on my board; that makes the gain lower than intended. I've increased it to 39K, which then means I have adequate gain from dynamic microphones without using "...

As usual, with Apache there is no way to tell what reality will be until products start to arrive in the user's hands and people make actual measurements. It's easy to be quite skeptical of the measurements shown on the website: - The photos imply that both units are packaged in the same chassis, so...

Scott, I have really been enjoying my Universal Audio Volt 1 interface. I have not tried using Voicemeeter with it yet. What would be the benefit of adding this version to my setup? James WD5GWY Voicemeeter is the go-to app if you want/need a virtual sound mixer on your system. As Tony mentions, fi...

It seems that Apache Labs people rarely, if ever, look at the forum, and even more rarely post anything.

Are you posting here because they are not answering your emails?

The most exciting thing is that an ASIO hardware interface is no longer required to use Voicemeeter.

Also, for an extra charge, you can enable all of the hardware channels as additional virtual channels.

The minimum allowable size of a Thetis window is 1018 x 609 pixels. If your display cannot provide that much screen real estate then you are out of luck. James' idea is a good one to obtain more space but it appears that the 7" display you chose will still not meet the requirements since it is ...

So many of us have gone to P2 that we've obviously forgotten that .4072 is the correct value for SetPk under P1

Labeling that button "Power" is one of the least comprehensible things in the history of PowerSDR/Thetis. I made a custom button for my skin that is labeled "Run" and "Stop", a much more accurate representation of the state of the software, and only the software. The bu...

What was the rationale for 20dB of gain? The CODEC IC already has piles of available gain. Why not 3dB or even 0dB (unity) gain?

As I posted, it is indeed a 5534. Gain is set to 10 (20dB voltage gain).

@lauchlin -- are you running Protocol 1 firmware?

There's nothing wrong with those results if you are using two-tone. As previously mentioned the dotted line is an artifact of the two-tone waveform. What power level was being used when you grabbed those screenshots? However, you may want to revisit your SetPk value. Make note of the current value, ...

Laurence: can we publish the schematic for the balanced mic preamp?

It might be helpful if someone who is having distorted audio problems could put an oscilloscope to work and see what was going on. Perhaps on some of these boards the NE5534 is going into oscillation.

That's a beautiful connector!

Okay this seems to happen only with my electret mic. It seems that the audio is lower if I use the MOX button. But If I use my dynamic mic there is no difference in xmit audio level whether I use physical ptt or mox. Maybe something with bias voltage switching in. Assuming you mean "PTT switch...

You are using the second ADC for RX2, with a separate antenna?

So if I understand you correctly from your original item 2 most mic/headphone setups get their bias supplied on the ring.....which would mean that the bias being supplied to the mic would in fact be the 3.2 volts on the logic input that puts the rig into TX.....which will of course dis-appear when ...

I cannot duplicate your results.

Is the DEXP and everything else 100% identical across the board except for the state of VOX?

What happens when you use MOX with VOX enabled?

Bottom line .....either there's a hardware mistake somewhere, or theres a software fault thats been there for ever. There's nothing wrong with the hardware or the software. There is something wrong with your mic wiring, either inside the mic or inside the cable or both, that is causing the problem....

Laurence: he wrote above that it is an RE320, which is a dynamic mic. Thus lack of phantom power is not an issue.

It is conceivable that the cable could be bad. @MW0XDT do you have a way to test the cable with another piece of audio gear?

ASIO4ALL is an ASIO wrapper around WDM.

Both openHPSDR mRX PS and Thetis can happily be installed at the same time on the same PC. No special methods are necessary, just use the normal installer for each. There's no need to run one or the other to enjoy different settings. Both Thetis and openHPSDR (aka "PowerSDR") provide a com...

Do I need to install HPSDRBootloader, or just HPSDRProgrammer, in order to set the ANAN static IP and NIC priority? To clarify: you don't use either of those utilities to set the Network Metric (what you called "NIC priority"). You do use them to set the ANAN IP. In a multi-NIC environmen...

Running FW 2.2.2 with Thetis 2.10.3.6 dev_2 on an ANAN-8000DLE. No problems to report at this time, but it's only been running for a few hours.

IMHO this is not an unreasonable request. People with noisy shacks that have fans running, etc. often have trouble with background noise. Conceptually it would not be hard to use NR2 on the transmit audio. Of course you probably are aware that the console code in Thetis is quite complex (complex bei...

Everything you need to know about Bootloader and the various versions of Programmer is in this topic: https://community.apache-labs.com/viewtopic.php?f=18&t=2333 I prefer to use Bootloader because it always works no matter what firmware you have loaded. NIC priority is a Windows setting and has ...
