Hi Mark,

<Sigh> Yeah, the forum is a bit messed up right now :roll:

As you and everyone else have undoubtedly noticed, the forum went down hard some three times over the last month or so. I've been working diligently with Apache's IT person and hosting provider to improve the situation, but it ...

We need some more information, Ed.

How do you have the Anan connected to the PC? Is it directly connected or connected via an Ethernet switch?

Are you running Protocol 1 or Protocol 2 firmware in the Anan?

You say that you have used Bootloader to set the Anan IP, so it is assumed that Bootloader ...

In another thread I posted results from flashing of many FW versions (see "Final" table below). Will need to dig deeper to determine which FPGA the Orion MKIII board has on it.
Not at all. You have a 5CEFA9F31 Cyclone V series FPGA in your 7000.

This is unambiguous. All of the firmware versions ...

Juha--did you follow the very first link in the very first post above, and read it? That's the answer.

Although that is posted at the Protocol 1 firmware repository, it is equally applicable to Protocol 2, of course.

Finally, as long as Bootloader is working correctly for you and the 7000 in ...

Every part of Thetis is open source, licensed under the Gnu General Public License (GPL).

WDSP is the DSP library used in Thetis. The "official" repository is here: https://github.com/TAPR/OpenHPSDR-wdsp

As long as you can abide by the GPL requirements WDSP is free to use and modify.

The de facto ...

AFAIK the Radxa CM5 is the best you can do for a CM4 form-fit, pin-compatible replacement.

https://community.apache-labs.com/viewtopic.php?f=48&t=5162

The Pi CM5 is 2+ times better than the CM4, the Radxa a bit better than that.

The cable will go between a serial "COM" port on the PC running Spark SDR and the SPE amplifier. That COM port can be a USB-to-serial adapter.

This link is probably going to be your best bet: [url]https://www.mtcradio.com/spe-expert-amplifier-interface-cables-by-dan-tassell/[/url]

Have you calibrated your power amplifier?

See this video:

Thetis has no idea.

One of the failings for the hardware design is no provision for machine-readable board revision data. Adding that feature would have made firmware and software updates SO much easier!

If the seller is willing to do some tests for you, the version of RF/PA board can be determined as described here:

https://community.apache-labs.com/viewtopic.php?f=35&t=2338

Any version will accept an input from and external coupler. The Rev. 15 & 16 boards benefit greatly from the addition of an ...

Have you seen this topic that discussed a successful swap out of the CM4 for a Radxa CM5?

https://community.apache-labs.com/viewtopic.php?f=48&t=5162

That's pretty complicated. Why not run everything on the radio PC and simply add the second screen permanently to that PC? HRD does not require very much CPU at all, it should not affect Thetis in any way. You can easily try it to prove that's the case.

Also, with that arrangement of screens, why ...

Thetis, not Thesis ;)

To start it I need to have thesis running on both the main screen and the shared screen with the other computer off.
Then I need to start setup and shift the setup screen to shared screen. That sets the setup to the shared screen, If I switch off the computer, setup will ...

Can you get into the database manager? If so, then create a new, fresh database and make that the active one. See if Thetis setup works properly with the new, fresh database.

Just to clarify, there is both a CM4 thermal sensor (a standard Raspberry Pi feature), and a thermal sensor on the PA board. What the firm/middle/software does with that data is unknown.

You can definitely see what the CM4 temperature is using standard Linux tools, but that's not very helpful since ...

I just looked at the PA board schematic. I may have missed it, but I saw no thermal protection hardware in the design.

There is a thermal sensor that reports back to the firmware and, I assume, back to the software. I don't know if either the firmware, middleware or software will act on that ...

Yes, two-tone.

The standard tone values of 700 and 1900 Hz are quite distinctive. You've probably heard them on the air many times.

If you want to be a bit stealthier and not "sing the song of our people" :D , 70 and 190 Hz work perfectly fine for setting amp drive levels and amp configuration ...

Co-channel means "same channel". Another term of art is "adjacent channel".

Of course amateur radio is not channelized in the HF band. However, from the perspective of how our radios work, each ADC represents a single, very wideband, channel.

One might argue that the preselector bandpass filters ...

I looked at the YT video. That's an oldie but goodie. Gerald is 100% correct. Indeed, I normally run my preselector (bandpass filters) in bypass 100% of the time because I often like to look at two different bands.

The other thing to consider is that, in all of the Hermes-derivative Apache designs ...

Thanks, this is what I was thinking in terms of interference. I wanted to see what others thought though. I will say that I just watched a Youtube video by Flex Radios Inc and the clear message was that this was not supposed to be possible... based on their simulation.
I'm not familiar with that ...

Classic co-channel interference. There's not a lot to be done about it. Cranking some step attenuator in on receive will help a little, but at the expense of weaker signal reception.

It would be interesting to see the entire UI screenshot, with freq's, amplitudes and S-meter shown. And you might ...

Not seeing anything wrong. I recommend that the MAP option be unchecked unless it is absolutely necessary for the amp behavior.

It would be safer to use the VK Amps coupler. Any time an adjustable coupler is used there is a danger that damaging levels might be accidentally achieved.

Before going ...

I think you'll have to read through the code. You can find it here:

Only direct-to-consumer shipments over $800 are halted. Business-to-business shipments are still moving. Therefore Apache could ship to the their corporate presence in California.

Of course, "could" does not mean "will"

I believe it expects a hex FF, decimal 127, for the other direction.

Look at Bome MIDI Translator to modify the messages.

Thanks Mark! :)

Yeah, my answer was poorly worded and confusing. :oops: But then so is the naming of the various functions in our radios.

From the perspective of "diversity", which is really a poorly-named beamforming algorithm, RX1 is the RX1 you normally think of. But RX2 is, in fact, a ...

You may indeed be expecting too much. Only interfering signals can be suppressed, not random atmospheric noise. And it will only work to suppress interfering signals if you are "lucky" in your arrangement of antennas. Did you read this post in the tacked topic at the top of this sub-forum?

[url ...

One more thing to try in order to help debug the issue, would be to use a simple USB microphone attached to your PC and use VAC to transmit with that.

If all of your problems are centered around using the balanced mic input (erroneously called the XLR input), then:

With the possible exception of the ferrites, which have worked for some people but not on all bands, nothing you have tried will solve the problem, and you should already know this if ...

You know, you learn something new every day!

I had never realized this before because I don't have an transverters, but it would appear that on any Orion MKxx based model the subject XVTR port is switched between TX and RX, and when it is in an RX condition it is paralleled with the output of the ...
