Re: Transmit settings, noise gate or downward expander?
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?

I'm sure the folks on the Intercon Net on 14.300 were happy. 🙄

Use a decent microphone such as the Sennheiser 835, these are cheaper than HEIL.

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

Re: Open HPSDR Hermes (14 bit ADC, EP3C25) Transceiver Card
Hello Max, in many ways I agree with you. Particularly on HF. I will not be running Pure signal but I will only use my Hermes with transverters on bands that have a very low noise floor. As Simon says

Well,
I’ll be on 4m and 6m this summer – mainly 4m but 6m during the 6m contests. I also will be on 2m but 2021 wasn’t so good – only 5 days with decent E’s for SSB.
