Studio 1 SDR Software: Features and Performance

The Airspy HF+ runs on the standard SDRSharp software. The first thing you notice when selecting the HF+ on the SDRSharp menu is how simple the controls are. There is no gain control - the AGC algorithm automatically adjusts the internal gain for maximum SNR, whilst ensuring zero overloading. The only control is the bandwidth selector where you can select from 768 kHz, 384 kHz, 192 kHz, 96 kHz and 48 kHz. Browsing the spectrum without having to adjust the gain slider is quite a liberating experience and the AGC always seemed to optimize the reception nicely.

The HF+ is also compatible with the SpyServer software, which allows you to stream the data radio IQ data over a network. SpyServer saves network bandwidth by sending only the currently actively tuned IQ signal plus the waterfall data. This is in contrast to other SDRs like KiwiSDR which send only compressed audio, or rtl_tcp which sends the full IQ data. Sending the IQ data rather than compressed audio allows you to perform various DSP algorithms to the signal on the host side, such as noise filtering. Sending the IQ data (even if only a slice of it) still uses significantly more bandwidth compared to sending compressed audio however, so internet connections and wideband signals such as BCFM may not work well together over long distances and slow internet connections.

In all cases the signal of interest is optimized for best SNR without overloading the SDR. For each SDR we used the officially recommended software package. For the Airspy devices this was SDRSharp, for the ColibriNANO this was ExpertSDR and for the RSP2 this was SDRUno.

I've also used Studio1 for a long time, which is the predecessor to SDRuno. If I had to pick just one software package it would be Perseus V5. I've also used Console V2 & 3, the software for the Elad F2, and SDR#.I just wanted to put the software issue out there for your consideration. The Perseus software gives you a lot imo (trying to not step on any toes discussing this).blw-----------------------------------------

The hardware is great but for me the user friendly software (I like v4.1 just fine) is what makes the difference. toggle quoted messageShow quoted text On Thu, Jan 6, 2022 at 6:27 PM Mark Goldberg wrote:The SDRDuo is a 14 bit A/D at about 6 Megasamples per second. It needs a front end and mixers to receive what it does. The Perseus is a 14 bit A/D at 80 Megasamples per second. Receiving up to 40 MHz, the signal goes pretty much straight into the A/D without mixing. The SDRDuo does have a much wider receive frequency range, but for HF it is not a receiver in the same league as the Perseus. They are basically apples and oranges. If you want what is still one of the best receivers out there for HF, get a Perseus. There may be used ones available.There are other SDRs available with similar performance, at a similar price.73,MarkW7MLGOn Thu, Jan 6, 2022 at 1:57 PM CliffVK2NP wrote:Hello from Sydney,I have always wanted a Perseus but just been a little pricey , rarely used ones come up.

Unfortunately, you cannot buy this SW any longer, butthey show up from time to time on Ebay and forums.What sticks out for me is the fact that I am using the Perseus dailywithout any glitch. I had to replace the power supply once, but otherthan that, no interaction was necessary.The frontend is robust (I used to have two S9+65dB LW stations in theair, now only one, sigh), the noise reduction is very effective, so isthe spike suppression.Nico knows what he is doing when it comes to signal analysis.You either like the Perseus V5 or V4.1 software or not. If not you havelots of good alternatives which are mostly free of cost: SDR#, SDRconsole, HD-SDR etc.Are there alternatives? Sure. You are from Australia, so I would like tomention the WinRadio Excalibur. What is for us Europeans "coming fromthe other side of the planet" is for you in the neighborhood.I like mine as much as I like my Perseus. I got one with the DRM key, soI can listen to the morning news of the BBC DRM transmission. Works verywell.Perseus plus VAC software plus DRM software also works, but not soelegantly.Also the combination of the Excalibur and the Userlist-Browser worksfantastic (free software).In case you want to look into another hardware concept, check out theAirspy HF+ (used, no preselector) or the Airspy Discovery (haspreselector).At a bargain price, you get a 18bit system which works as a HOMOdnyereceiver, so IF=0 Hz. Not too many of those were around for shortwavereception in the last decades (Collins 95S-1 comes to mind).For the Airspy you have a distributor in the country, Connect VK, thuswarranty isn't an issue.Lastly, you already own a stationary receiver, you have one that needs aPC/laptop to work, what is in between?A fully portable SDR! Check out the Belka DX, the Afedri or the Germanmade RDR Pocket.Best regards, 73Ralph toggle quoted messageShow quoted text On 06.01.2022 21:57, CliffVK2NP wrote:Noise and high power MW stations are an issue at times. $('#quoted-198592145').on('show.bs.collapse', function () $('#qlabel-198592145').text("Hide quoted text"); ) $('#quoted-198592145').on('hide.bs.collapse', function () $('#qlabel-198592145').text("Show quoted text"); ) More All Messages By This Member

I have a Perseus and had an FDM-Duo, the Perseus is has superior dynamic range and significantly better close in PN performance than the FDM-DUO. Of course the S3 has a larger bandwidth but that is not something that I need. I still really love my Perseus for my applications. Surprisingly it is still able to hold its own.
