Negative.

Hi Scott, Now that you have replaced that two-port PCIe NIC, you should try and repeat your experiment on the "Interrupt Moderation" setting to see if you get the same results as before? 73, Bryan W4WMT Very insightful! I didn't think of trying that! And, as I suspect you are expecting me...

Will try your suggestion Scott and turn off unused item on the dedicated NIC for the Anan. This NIC is still showing as a public network even though I've changed it in the registry to private, any suggestions on that ? I have no idea. I don't mess with registry settings like that. I would guess, ho...

I've never been a fan of the V2 (P2 compatible) version of HPSDR Programmer. It has always been semi-reliable for me. I recently went through my own hair-tearing few days. Upgrading from a KPA500 to a KPA1500, I started to experience interruptions in Ethernet service to only a single port on my main...

That's some very good work there, Jim, and it would seem that it should answer Gary's original complaint that started this topic.

@NC3Z get that rework station fired up, Gary!

Found some suggested ethernet settings on this page from Flex https://helpdesk.flexradio.com/hc/en-us/articles/202118518-Optimizing-Ethernet-Adapter-Settings-for-Maximum-Performance I don't agree with all those settings, but it's a pretty good list, nonetheless. I'd leave buffer sizes at stock sett...

Time to start looking at the basics. Link lights of the correct color showing a good GigE link. Can you ping it? Etc. For instance: a bad cable can fool you. Bootloader runs in 100BASE-T mode. That requires only 4 wires on the Ethernet cable. If you are running Thetis and P2 that forces the link to ...

Low metric wins. Think golf score. Set the metric on the NIC that goes to the ANAN lower than the metric for the other NIC.

Nice! Moved it right out of the band. How did the other bands fair? Did you have a spur on 160 to deal with as well?

Here's an interesting one: on my Intel network interface card (NIC) I was doing some speed testing using iperf and was shocked to see the card only moving 150 Mbit/s. This is on a dual NIC, server type, PCIE card, and an i7 CPU, so it should be quite a bit faster. After poking around in the advanced...

But it's still going to be a high power relay, which means relay speed and relay lifetime. It's unfortunately that with all of the great hobby modules for solid state power amp's currently available, nobody has designed and produced a diode T/R switch module. They are somewhat non-trivial, particula...

My apologies! I thought the 7000 didn't have a preselector on the second ADC, but per that block diagram it clearly does. So there you go, even less of a difference between the two models!

I've edited my post above to make that correction.

Don't think of the 8000 as being "old". It is 90% the same as the 7000 and 100% the same where it counts. It uses the same preselector design, the same Orion MKII SDR board, and the same rear panel connector breakout board. There are some minor differences in the RF switching paths, and mi...

The 6M preamp will have no bearing on this problem given that it is on 80M.

As far as I know, nobody has ever experienced an S9 birdie (internally generated spur).

I see you have run the unit into a dummy load. Have you also tried running the unit off a battery instead of a power supply?

Moved: not an SDR Console topic.

I got this image right off of the Apache website. Easy day, right on the edge of the board.

In Thetis (and PowerSDR), the approach used is just like that done in laboratory test equipment. That approach references all measurements to the rear panel connectors. Example: if you have a signal that is -80dBm at the rear panel connector and the attenuator is set to 0dB, it will displayed as -80...

I personally do not care for auto AGC gain. The original AGC algorithm normally takes into account the attenuator setting, but that feature is lost when auto AGC gain is used. This has the effect of losing any additional quieting associated with increased attenuator settings. I suppose many people w...

IMHO, NR2 and the AGC in Thetis are superior to any other receiver available, so I have little to offer you in terms of how to make it better. I can copy signals with Thetis that are barely above the noise floor, I've never been able to do that as well with any other radio from any other manufacture...

First, it's Thetis, not "Thesis".

Second, frequency calibration should be performed in DSB mode.

Perhaps your title should read "undercompensation"? Funny, two separate questions about the same thing at the same time (this one and one about the 8000). See this topic from back in 2017: https://apache-labs.com/community/viewtopic.php?f=17&t=2652&p=4413 Note that the power differ...

All audio processing is disabled on Quick Playback.

At one time there was a bug whereby CFC was not disabled properly during playback.

That bug was fixed in the initial release of Thetis 2.8.11

Yes, it's unfortunate that Apache still hasn't let them be posted publicly here on the forum. They have to supply them under the hardware open source derivative works license, but they don't have to make them publicly accessible, apparently.

"Bricking" is a a very, VERY rare occurrence, and I would not worry about it. Most of the incidences of "bricking" occurred because of a memory configuration mistake made at the factory in a batch of new units that came out immediately after a part number change to the memory IC....

VAC1 is dedicated to RX1 and, for lack of a better term, "TX1".

VAC2 is dedicated to RX2. It has no transmit facilities.

Within those limitations you can certainly use either for CW Skimmer receive.

You posted a screenshot of VAC2 settings. That implies you are trying to transmit audio via VAC2. Regardless of the fact that VAC2 allows defining a transmit audio device, transmission via VAC2 is not supported, only VAC1.

Check your math, Jim. It's 140K not 1.4M

My conclusion, RX2 circuit is not as bulletproof as the main antenna input of the radio, which it is REALLY bulletproof. Opinions? Thank you Gus. You have a 200D. There is no preselector (bandpass filter array) on the RX2/ADC1 (second ADC) input, only on the ANT1/2/3/ADC0 (first ADC) input. You can...
