Re: RSP2 frustration on Mac

Personally i would gladly pay extra for something that would work natively on the Mac, guess for now we all have to wait. As I have said before, the great frustration for me is that every person I know involved with radio uses a Mac desktop, and we are all saddled with having to use Windows in a VM...

Re: RSP1 Off Frequency - by a lot!

I'm assuming you are using the RSP1 as a stand-alone RX, not as a panadaptor? There could be a few things that may cause this, but first check on a few known frequencies (perhaps AM broadcasts) to confirm that there is really an error or not. What you are hearing may just be an image response. If th...

Re: RSP2pro vs cheap RTL ?

The SDRPlay receivers are head & shoulders abve the RTL-type dongles. I started off with a dongle, but the noise level was high and the dynamic range was poor. The RSP-1 pushed the noise level down and there was far less tendency to overload. Of course you will only see the benefit of the lower ...

Re: Broken wire

Phil - the leads are mini coaxial cable, and it seems strange that one of them should become completely broken unless you didn't notice when the socket came loose and you carried on twisting until it snapped. SMA connectors are not the best mechanically and you have to be careful with them. I find n...

Re: RSP2 front-end protection?

Hi Ian The internal screening of the RSP2's plastic box is continuous as far as I know and forms a closed screen around the circuit board. It is grounded to the 0v of the electronics. I doubt the 'pro' version is any better. As for protection, I think it uses the usual back-to-back diodes and accord...

Re: RA0SMS Miniwhip bad performance on SDRPlay

My experience with mini-whip type antennas has not been good, but that's because this area has a high noise level. This type of antenna is very good for its small size and excellent performance at LF, but it is wide open to local electrical noise. In contrast, my Wellbrook loop reduces the noise fro...

Re: RSP2 Upgraders - What Do You Find Better than RSP1?

Hi Noel, you might like to take a look at this. Although there is a mis-match between a 50 ohm antenna system and the 1k Hi-z input, it works just fine and gives better results than the SMA inputs.

Re: RSP2 Upgraders - What Do You Find Better than RSP1?

I agree with everything I3DKA has said. The three selectable antenna inputs are very useful as it saves mucking about with external switches or diplexers. The Hi-z input produces a lower noise floor than the two SMA inputs on LF/MF/HF and as it rolls off above 30 MHz the annoying FM sproggies are go...

Re: Notch Filter and antenna ports for RSP2

The AM notch is designed to stop images from the AM(MW) band popping up in higher bands like SW and VHF. You would use antennas A or B for listening on VHF, so that's where the notch filter is fitted. You wouldn't want to notch the AM band when listening to the AM band via the Hi-z port. I find the ...
