Yes,
Then add PS.

Re: Open HPSDR Hermes (14 bit ADC, EP3C25) Transceiver Card
Simon,
I agree. Good modulator, filtering, clock and RF design and use of quality parts can eliminate the need for after the fact PS cleaning. A cost benefit analysis would show which method is most

FWIW I have never seen bad splatter from an IC 7300. I couldn’t care less about lab measurements, it’s what I see on the sir.

Hello Simon.
Yuk! That is indeed awful.
I will ask OT4A what he is using, I seem to remember that I have had problems with him on 6m from time to time.
I am sorry but I really must take

Conrad,
Watch: https://www.youtube.com/watch?v=NaGPZzGDKeU OT4A’s signal has got worse since this. I think he has a big OM Power amp but am not sure.
The IC-7300 close-in signal is superb.

Re: Open HPSDR Hermes (14 bit ADC, EP3C25) Transceiver Card
If there are enough excellent signals then maybe slowly the culture will change. When the manufacturers move on to a clean TX being the marketing differentiator then I am sure it will improve. Why is

Re: Open HPSDR Hermes (14 bit ADC, EP3C25) Transceiver Card
Mark,
What your description below shows is a very poor PA somewhere in your chain. I agree that PS can clean this up and indeed should be used, but for myself the first step would be to generate

OK,
Now I have time to think about this.
Let’s see the firmware you have installed: Click the Options link in the Radio window, select the Firmware tab, show me this. My current firmware is

That sounds VERY much like auto-mute is turned on.

tools menu->options
Click on "Auto-mute" on the left.
On the right make sure "Enable" is not checked. The auto-mute function is on the lower right and is worth reading.

OK Simon thanks. I am sure that you realised that I am just (im)patiently waiting for hardware and getting bored.

Never attribute to malice what you can attribute to ignorance and/or stupidity. "Maybe I'll get better reception if I turn everything up real high" might be one example (although I admit it's not

Re: Open HPSDR Hermes (14 bit ADC, EP3C25) Transceiver Card
If you had an Anan you could see the difference graphically with the two tone test.
Depending on the amp it can be quite dramatic.

Transmit settings, noise gate or downward expander?
I was looking at the TX audio section, which I have not used yet. I cannot see a noise gate or downward expander, perhaps I missed it. If it is not present is there any possibility of adding one?

Re: coexist SDRuno 1.41.1 with SDRconsole3.1 with RSPdx?
Hi Folks,
did now a no antenna test like jdow suggested.
But first of all, if I switch the AGC to on the SDR RX went quiet and no spectrum/waterfall is displayed. So
