you can report bugs over on github which makes things easier to track

Thanks, Richie.

I'm not sure if it's by design, but I'm seeing a PA Profile banner inserted into Thetis' display when alternating between screen expand and collapse. At least in my case, it overwrites onto the custom containers. A right-click on the banner opens up the PA settings window, but there's no option to r...

I'm running a 7000DLE MKII (soon to be replaced by a G-2-1K) CPU usage on mine pretty matches the System number but the Thetis-only number is a bit low compared to what System Informer shows by about a factor of 2. System informer is MUCH better than task manager. https://www.systeminformer.com/ Mi...

would there be 11m signal from the radio when on the 10m band? Doubtful but you can verify the presence of a <28 MHz RF component with a general coverage receiver or a TinySA handheld spectrum analyzer. https://www2.randl.com/index.php?main_page=product_info&cPath=16_16990&products_id=75961...

Thanks Jim for the information. I looked at that diagram before I posted the question. Now after looking at it again, I am totally unable to figure out how you got 16 or 32 ohms. According to the datasheet, the TLV320 output Z at the headphone output pins is close to 0 ohms -- like many active amp ...

Are relays still used for T/R switching or does the G2 use pin diodes? If relays, any differences from the 7000 series? Specifically, is the pure signal relay still in parallel with the T/R relay so its always used even if the mode isn't SSB? Thanks Ron N4XD Ron, Good questions, and I hope someone ...

...My microphone is a Neumann TLM103MT with a 1 tube mic preamp/phantom voltage. In time, perhaps reconsider the real need/want of a tube preamp and replace it with an ASIO USB audio interface device. Some benefits: 1) Minimal noise and distortion through a well-designed mic preamp stage with optim...

Hello Paul, Someone had said that the ANAN's didn't need such a circuit so I stopped using one. A round about Lesson to remember that's for sure. Ken WB4AM A common mistake is assuming that the current-carrying capacity at the PTT Out jack is the same as the open-drain current rating as shown on th...

I wouldn't normally recommend an amplifier key line buffer when using modern amplifiers, but several instances of PTT line transistor failure have occurred after various surge-related events. In my experience, switching FETs are more prone to voltage spike failure than bipolar transistors. The buffe...

As you can see the height of the waveform isn't as big as it could be! The window is much larger. It would sure be nice if one could increase the sensitivity.

Scope sensitivity is a function of: (1) the Rx AF control; and (2) AGC Gain control.

I ran into an installation issue with Thetis v2.10.0, then reverted to G7KLJ's v2.09.31. After installation of v2.10.0, Thetis' startup window showed 1900+ seconds and each successive restart took nearly that long. Before installing v2.10.0, the old Thetis version was deleted in Windows' program add...

I will post some numbers. I also re-installed an old Thetis, same results. FWIW, I see the same bizarre 6m SWR behavior with my 7000DLE. Thetis' SWR is all over the map when transmitting into an open circuit, changing the ANAN's ANT ports to open versus closed, but always reports 1:1 into a 50-ohm ...

Some more explanation. Some of the capabilities of the 590 (e.g. morse padddle input and keyer, not implemented on the HL2) are easier to access and the 590 is 100W output vs 5W on the Hermes Lite 2 (although I have a TL922 interfaced and teste with the HL2/Thetis). The CW shortcoming is easily sol...

Riche,

Thank you for the many miracles you've performed over the last few years. Hope to work you on the bands one day.

Paul, W9AC

It may be worth attaching an ultra-stable 10 MHz frequency reference, then observe any changes in frequency behavior.

"However they do provide an optional pin for GND that is for the XLR locking tab." Although not clearly seen in Neutrik's PDF datasheet, the optional ground pin connects to a thin metal strap. The other end of the strap is formed into the mounting hole of the plastic XLR enclosure. As a p...

I'll pontificate: to make best use of that series jack (whether standard or mini XLR) requires passing a screw through the panel to avoid the so-called "Pin 1 Problem." It's almost certain that PCB-mount jacks will be used. Although difficult to see, Neutrik provides a conductive strap bet...

Obviously the software and firmware doesn't come from a "manufacturer". Supporting hardware includes Apache, Red Pitaya, Hermes Lite 2, and TRX Duo--am I missing anyone? Yes, if we consider predistortion development separate and apart from those involved with PureSignal. The ADAT ADT-200A...

If I understand correctly, Pure Signal should improve the out-of-band spurious performance of a linear (i.e. second, third, etc harmonics) in the same way that it improves in-band splatter (signal width on the waterfall). A question: is it reasonable to assume that Pure Signal can clean up the outp...

Steve, Some of us HL2 users have added an HL2+ companion audio board. Awhile back, I experienced some difficulty finding a compatible version of Thetis but did eventually. The companion board eliminates the strict need for VAC and operationally, is much like Apache’s Orion boards. Does 2.9.0.11 supp...

Here's the deal on the PIN diode PA board schematic (which I'm guessing should not have been publicly posted): No units have shipped with this design, and none are going to. As Laurence has already mentioned, achieving reasonable linearity performance with that (and other) designs has not yet been ...

Good question, but I don't know.

Paul, W9AC

w-u-2-o wrote:How do you know this, Paul? Have you seen schematics?

Yes, I have the full schematic of the V.14 PA/LPF board which shows a moderately complex PIN diode T/R structure. It's significantly different than prior boards.

Paul, W9AC

w-u-2-o wrote:Based on the history of RF board designs it's more likely that the G2 will use the same RF boards that are in the 7000.

The new PA board revision shows PIN diode QSK T/R switching.

Paul--thanks for posting this. It's a subject worthy of a new sub-forum, so I have made one! :) No doubt there are going to be a billion questions. I've already sent a long list of them to Abhi, Laurence and others. I will report what I get back. Thanks, Scott. I edited the first post as I believe ...

A new SDR transceiver (or Orion board alternative) is in the works from Apache Labs. Among other new hardware features, take note of the PCIe interface and "thin client" remote possibilities. Price TBD. https://apache-labs.com/al-news/1033/Introducing-the-Next-Generation-Saturn-SDR-Platfor...

Bhanu, Just to be clear, the sweep utility under the "Tests" tab sweeps only audio frequencies at the VFO's carrier frequency. It does not allow for sweeping the RF carrier as is normally the objective when sweeping RF filters. The ANAN's RF carrier frequency remains fixed. So, for HF filt...

With the little time I've spent with the update this morning, the only suggestion I have for consideration is a dockable container option, vertical edge meter option, and possibly an option to automatically hide metering functions that don't apply to a specific operating mode.
