Mine must be a database problem - reset from scratch and the RFI disappears.

Thanks Mark - tried that bit no joy.

Started Thetis v2.10.3.5 this afternoon - appeared to load normally, but when I hit the 'power' button in Thetis, it took much longer to hear the relay click and the panadapter to start, and then I saw this on 40m: Capture.JPG Posting here, because starting up with a blank database, everything seems...

Properly set up, you should be able to drive sufficient mic audio level into Thetis to trigger PS Feedback without the Motu meter ever going into clipping. Thanks Mark - out of interest what mic are you running? I think I'm in a much better place now - most of my trouble appears to have been my poo...

Thanks Scott - yes phantom power is on. Clearly a boom arm is now on my shopping list.

If I shoot for ~ -3dB peaks on the MIC meter via the gain on the Motu (VAC TX gain at 0dB, TX eq off), I do see some minor clipping on the Motu display on the pops and whistles. Maybe thats ok?

I've been getting reports of 'background' noise in QSOs for a long while. My operating position used to be in a room with nearly all hard surfaces so I attributed it to that, but have now moved to a different spot which should be better and it persists, so I think something in my setup must be off. ...

Mark, Nobody has a hardware architecture that will support it, with the possible exception of Flex and perhaps such niche products as SunSDR. Hi Scott - I'm on an old IC-7610 Icom mailing list and recently I saw some chatter about the (maybe?) forthcoming PW-2 amp and it's marketed Industry First D...

Too easy - thanks Scott

Hi - probably a simple one. For a while I've noticed that if i switch from USB/LSB to AM, my active VAC deactivates. Is this a setting I have somewhere? P2, 2.9.0.

Just for interest, I found Acoms reply when I raised the two tone test issue years ago: I remember there was such an issue and thought it was fixed many years ago. it was not made intentionally of course. Just the frequency counter software did not manage to read the two tone signal frequency correc...

I posted a question on the Acom groups.io forum re disabled 2-tone test in Acom ss amps. Here is a response I received: I raised this with Acom for my 700S and was told its intended to avoid a problem the frequency counter in the amp had with the test tones Don't know with certainty this is the cas...

Thanks for digging into that Scott. I typically only use it as a large screen power meter as it sits some distance away from my desk, but stumbled on 'spectrum display' and got curious.

I have an LP-500 meter that has a spectrum display. I noticed that it does not seem to display the IMD improvement from a 2 tone test with PS on vs off. Apparently the LP-500 coupler needs a 200hz sub-tone to properly display a two-tone test on the spectrum meter. The 2 tone output on the meter prov...

Brilliant Scott, thanks. I will go through the links. I'm using a magnetic receive loop for my 2nd antenna. Moved it as far as physically possible (probably 1/5 of a wavelength on 80m) from my main EFHW and now am seeing some results. If I'm understanding correctly, I have a challenge in that the no...

I'm muddling my way through trying to use Diversity to null out a local interference source (power pole in my street). Read all the posts here, but can't get my head around whether significant spacing between my main and 'interferer' antenna is needed, and haven't found a suitable beam-forming 101 r...

Well - early days but looks like success.. Tried another amp and was able to reproduce the same behavior. I noticed that with my TX EQ enabled it was much easier to cause the problem. Set a new profile from scratch and it has been 100%. Even with PS-off the TX spectrum looks MUCH better. Possible a ...

I also see PS 'fails to launch' sometimes. In this series of two tone tests, PS works intermittently. I see this when operating phone - on some overs it doesn't give any indication at all, and from the spectrum it is clear it's not doing its magic.

I managed to capture an example of my TX spectrum and AmpView exhibiting the symptoms that lead to my Amp faults. I'm using a dummy load here and things look normal with PS in the first count, but counts 2 and 3 seem to show something wrong. Only occurs with PS on. https://youtu.be/KoKEN4V8W2M My se...

Thanks Scott. I have had good support from Acom so far. I've just queried them re. the two tone behavior and if they have input on potential impact to adaptive pre-distortion. I'll share what I hear.

Yep - I've seen that and worked around it by changing the frequencies in the Two Tone test in Thetis. Is your hypothesis that potentially whatever is in the Acom firmware to disable 'standard' two tone tests may be a trigger to this behavior? I also noticed my mic level in Thetis is exceeding 0db by...

It's an Acom 700S.

PS feedback is via a modified Telepost coupler with a -55db sample port. I do have a -44db Xtronic one here I could swap out. I could also try Thetis 2.6.9 or a different fw (running Metis_Orion_MkII_Protocol_2_v2.0b).

Cheers

(G'day Scott - feel free to move this to the PS or Amp forum if more relevant) Did a little more digging, and PureSignal seems to have something to do with my amp tripping issue. When the trips occur, momentarily the TX spectrum looks horrible and overloaded, the PS indicator is blue, and Amp View s...

Next time you see this happen, just bump the drive up one or down one and see if that solves the problem. It happened a couple of times over the weekend. Changing drive didnt seem to help, nor changing the CAT ports, however turning PS-A off and on again restored normal operating. Really not sure a...

Looks like John (the PiHPSDR developer) just added the ability to auto start if a single radio is discovered to the main repository.

If you press TUNE again does that make a difference, or does it really need a restart? Hi Laurence - in my case it seems to absolutely need a Thetis restart. I'm not certain I'm seeing low Tune power in my instance. if I put the amp in standby, I do see the expected tune power bypassed through the ...

Probably would have been marginally helpful for me to include some detail:

Anan 7000DLE mk2, P2, Thetis v2.7.0,

G'day - I think this is a Thetis question, so posting here.. I see some weird behavior from time to time that I can't quite figure out. This is usually when I've done something dumb and caused a soft fault on my amp and it goes into Standby, but also on occasion when I get a hard fault and the amp s...

Perhaps someone else might chime in with a better answer? I use PiHPSDR with a Hermes Lite 2 in my truck. Christoph DL1YCF recently helped me modify discovery.c to include the option of auto starting a discovered radio that matches a specific HW address. I'm not sure if Christoph plans to include t...

I am, but think I'm getting more out of it now I'm driving the audio properly, Who'd have thought reading the stickies/guides would help.
