Re: magnetic loop and pre-amp?

I have been using my three diameter loop with my SDRPlay RSP-1 without a preamp for a few weeks now... I see all sorts of signals. If you are seeing nothing, check your loop construction. You should hear a pronounced increase in background noise as you tune through resonance. Make sure you are liste...

Re: Earthing my new SDRPLAYduo

I have mine tied to the station ground, which is a eight foot ground rod, and that ground rod is tied to the service entrance ground for electrical. Multiple grounds, not tied together, scare me.

Re: RF "surges"

I am using HDSDR, and had the same issue. I killed the AGC, and added an attenuator on the input of the RSP-1. I try and keep the input levels reasonable to the radio using the attenuator. I also keep the system gain as low as I can for whatever I am doing at the time. I further added an AM broadcas...

Re: Feedback for version 0.9a here

I was showing a friend in the communications business the Spectrum Analyser, and his first question was, is there a way to hear the signal? I did not find a demod, did I miss it?

Re: Feedback for version 0.9a here

Hello, If possible, please leave in the ability to show a full 24 hour period of time in the actual displayed waterfall. Having data as a separate file would be useful as well to break out the start and end times exactly. I currently use different software to for this. Having one piece of software d...

Re: Feedback for version 0.9a here

Feature Request: 1. The ability to control the waterfall speed. I sometimes need to capture a 24 hour period using waterfall to show start/end times of an RFI event. I currently use HDSDR to perform this. Having the SA waterfall able to capture a 24, or 48 hour period of time would be very handy for...

Re: Feedback for version 0.9a here

Feature request: 1. If the Save and Load buttons could be activated to save the current state of the analyser setup it would be great. I am preparing a set of analyser screenshots showing a 500 KHz section of spectrum containing RFI, both with and without the RFI present. Between runs I need to manu...
