Uninstall/reinstall had the desired effect.

Digging the new offset setting for the automatic minimum panadapter level

Once upon a time there were some bugs in Thetis regarding PureSignal, such that it might become inactive, or might require an off-to-on cycle of the PS-A button to get it going again. These have been fixed since 2.9.0.x came out. If you aren't running the most recent version (it doesn't have to be t...

I did an over-the-top install, and everything seems to be working, but I can't tell if it is 2.9.0.5 or not. The title bar says "Thetis v2.9.0 x64 (4/4/22) (Protocol 2 v2.1.18) MW0LGE rev4"

Is 2.9.0.5 to be installed over the top, or should there be an uninstall first?

I obtained the dual port NIC as suggested above. I'm about to tackle the settings as were outlined. If using one the the ports for my general internet connection, should the port settings be the same as the old Mobo Port Settings? The one port is currently connected to my Router/Modem setup and see...

8000 & P2

Ouch! Yes, it would be better if the fourth digit did not kick off a DB reset, while the third one did. That would work fine.

To prevent a legendary amount of thread drift, I have moved the Apollo amp discussion to this topic: https://apache-labs.com/community/viewtopic.php?f=17&t=4157

@LA2NI Kjell you misunderstand about "where does the software reside". Restated: where can one find the source code and other information necessary to program the controller on the Apollo? In fact, right now there is no usable schematic, BOM, assembly information, programming information, ...

Great progress. 70/190 is not the optimum tone pair for checking IMD, but it provides a reasonable estimation of performance, and will work well for testing drive level, making drive adjustments, and getting an initial PS solution. In addition to working with "difficult" amp's, 70/190 also...

Richie--would it please be possible to increment the "x" in 2.9.0.x? And to show the entire version number in the title bar? Configuration management is becoming difficult without this.

Thanks,

Scott

If you want to report SNR in S-units, just take the PBSNR value and divide by 6 in your head :) or use the option to do it for you, again in options 2 Ha! I was not quite yet on the latest beta. But I am now :D On that note, playing with the new "Adjust Min to Noise Floor" setting, as you...

May be I am wrong, but this measuremet is dB and not dBm. Agree with this. Please change to dB. [Not sure what PBNP is. That is "passband noise power". It is a real-time estimate of passband noise power based on the power measured in the panadapter RBW (resolution bandwidth) and as displa...

Richie--the ADC/ATT/RX combinations are many, as you know. If you'd like to post a list of tests for people to verify functionality on the various hardware types, Hermes to 8000, and people ran through the list, would that be helpful to you?

Yes, please do try 70 & 190, it would be very interesting to know if that works for you.

Thanks, Rob!

Chip, I thought the RF2K amp came with a built-in coupler that is placed, internally, between the amp and the tuner sections? The photos on their website show a -55dB coupled output port. For those who have an amp with internal tuner, the choices are as follows: - Don't use the internal tuner, use a...

2. Without the external 6 dB pad I see an S-ATT value of 25 when running about 500 watts on 40 m. In a previous post I inquired about the possibility of exceeding the max input level to the 7000DLE and Scott advised adding some additional attenuation “to be safe.” Added the 6dB pad as a result. Thi...

@ramdor Richie-- the Two Tone CAT command is broken. Two Tone is set to "Use Drive Slider". TUN is set to "Use Fixed Drive". Using the 2TON button on the UI works as expected: drive power is achieved. Using zztu1; 2TON is produced at the tune power setting. If TUN is changed to ...

Those are some great points, Paul. Some definite potential for damage (ha, a pun!).

With regard to the impedance issues: that's why I'm curious to see some screen shots from the OP.

Kjell,

Is the schematic at the following link still valid on the new PCB?

https://openhpsdr.org/wiki/index.php?title=Apollo_-_Development_Discussion

Is there a BOM?

Where does the microcontroller code reside?

Thanks,

Scott

If the coupler truly has 50dB coupling factor then you probably don't need the 6dB pad. You can determine this from the step attenuator value during transmit. If it really is a 50dB coupler, then plus the 6dB pad you should be seeing a step attenuator value of approx. 16dB at 1200W. Removing the 6dB...

Where is any of this open source info currently located, Kjell?

The14 bit Hermes is the same board that is in your 10E. IMHO you don't need a preselection (BPF) filter board unless you've got some nearby broadcast or amateur stations. I don't believe there is one in the -10 or -10E. The Hermes by itself puts out 0.5W. 1 and 2 watt amps are a dime a dozen on eBay...

Mike, Welcome to the old days, when Hermes was for hobbyists :D What you really want to do is start dredging up the old information from those original Hermes hobbyist days. You can start here: https://openhpsdr.org/wiki/index.php?title=HERMES Follow all the links you can find. You will want to find...

Scott: Since there IS a second number shown - and my best estimation was that it was showing the signal level relative to the floor - i.e. db above the noise floor - I assumed that all the math had been worked out and it was a genuine number. What it shows is the power level in that RBW bin above t...

Glad you got it sorted, Ruben!

The internal RF signal paths on the 7000 do not support EXT for external PureSignal feedback from a coupler. You have to use the Bypass input and select the option for Bypass on TX. Be careful with the CleanRF product. The adjustable versions are easily capable of generating feedback levels that can...

With Rick's, N1GP, kind permission and assistance, the Quartus archive files ("qar" files) for the latest versions of all variants of the Protocol 2 firmware, from the 14-bit Hermes on up to the Orion MKII boards, have been posted into the top post of each P2 firmware topic here (the stick...
