Re: Implementation of Pure Signal by Dr. Pratt in other radio

It's more than that. First, remember that "the radio" is primarily contained in software element. The hardware element is little more than the front end and the first IF conversion. That means that any SDR that provides an appropriate feedback path and utilizes Thetis (or even PowerSDR mRX...

Re: VSPE, which is a good one to download

If you are connecting a tuner (or any hardware device) to the PC using RS232 serial communications and want it to communicate with Thetis, no "VSPE" is necessary. Merely assign the correct COM port in Thetis (Setup > Serial/Network/Midi/CAT > Serial). If you need to make a connection betwe...

Re: Is it worth upgrading from early 100D/200D rigs to latest Anan hardware?

Some additional thoughts: The newer hardware has a more effective thermal design. If the hardware is run at 100W all the time that may or may not be something of interest. That said, on the older 100 and 200 series units, the simple expedient of getting a small fan to blow across the top of the chas...

Re: Is it worth upgrading from early 100D/200D rigs to latest Anan hardware?

Leaving aside the 14-bit receivers (10E, 100B), there's little practical difference between the original Hermes and the latest G2 hardware. Most of the improvements are only easily measurable on the test bench and are relatively invisible given real world conditions. Indeed, if you study the schemat...

Re: DU3500AL Auto-Tuner w/ Anan 7000DLE MKII and OM2000A+

It's rare that we see a PC these days with anything but USB and Ethernet ports. The tuner provides an RS232 interface for communications. Thus an RS232 interface (aka "COM port") will need to be present on the Thetis PC. This means either adding an appropriate PCIE card (desktop PC) or a U...

Re: G2 distorted audio using TRS and standard mic input

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...

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.

Major new version of Voicemeeter now in pre-release

https://voicemeeter.com/voicemeeter-updates-february-2024/

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.
