That is right.
Tnx for link.

Re: RSP Spectrum analyser software available shortly

@Steve Just to inform about first bump along the way ;) Arduino Virtual COM Port in Windows 10 Device Manager installation, without Arduino HW is impossible mission so far. Here have only RPI 2B+ available. Must consider other way around :mrgreen: RSPSpectrumCom.jpg Like this COM1 created with trial...

Re: RSP Spectrum analyser software available shortly

@Steve
Your SW is running nice on my RSP1 and W10.
Installation went smooth.
Thank you for kind words in "Release notes".
Expecting to have my ERASynth+ in hands soon.
So now some bridge SW must be written in between ;)

Great work

Re: Newbie RF frontend protection Qs

18 MHz only?!
My circuit (above) is working nice up to FM broadcasting band.
Above that, on Aviation AM band can hear the difference.

Dear Phil,
it was pleasure to read and write some comments on this important topic.
My opinion is that your concerns about response time are just right.
I am using above device since 2015. on my summer stormy island location, so far no damage behind ;)

Re: Newbie RF frontend protection Qs

Hi Phil, The only reason of double in serial diodes use, is to avoid intermodulation during the evenings when HF signals are stronger. For the rest, please look on my schematic. Let's imagine few possibilities: 1. Diodes are ground for all +1,4 or -1,4V or more on input... if is to much current - th...
