SDRplay RSPdx review and interview

[@walteredwards544]

I don't know how I missed this but I'm glad I'm seeing it now. Very informative. Thank you again. Ciao

Great video! I just ordered the SDRPlay RSPDX! I have no transmitter (or transceiver) at this time but have a 300 foot long wire antenna tuned with a remote tuner. I want to use the RSPDX as a RX/Pan. adapter. My plan is to purchase a transceiver that has a clean transmitter, like maybe an Elecraft K3S (used of course). Maybe an Icom IC-7100 so I'd have 2 meters and UHF. With some sort of interface so not to blow up the RSPDX. That's my plan. 73 de WA3RSL.

Patiently waiting for the RSPdx to become available for purchase!

[@JamesJ7851]

I'm already own an original RSP1, going to the DX, waiting to gauge the performance difference.

I went to a presentation by that chap from SDR Play on Saturday at Martin Lynch & Sons. It was excellent.

I hope they will soon release a dual RX with the 14 Bit HDR mode and technology of the "RSPdx" because phasing between antennas for directional purpose or noise reduction is a great thing with enormous future, that would temporarily set these SDRs apart from the masses - would be worth every penny for every hardcore DXer. I do a lot of simultaneous decoding of e.g. HFDL signals within one band and here you can simply forget the SDR-Uno software - while SDR-Console support the RSP1A with its filters and its a walk in the park to receive e.g. 8 channels simultaneously piping their audio into separate virtual audio cables that go into separate audio decoders. In others words if you want to do more, don't use SDR-Uno, unless you want to use the new HDR mode (RSPdx), which is not yet implemented into the SDR Console, as well as diversity reception with software and level phase shifting (RSPduo). SDR Console is an excellent piece of free software with support of all RSPs and plenty of other SDRs for RX and TX, so please don't be focused on SDRuno with its utterly annoying windows separation that is even unable to maximize when single windows are being moved to other monitors ... it seems to be designed by someone who wants to give you the flexibility of good multi monitor use, but doesn't have any to test its real life usability. But one feature I like about SDR-Uno is its built in scanner app that most other packages (except SDR# which doesn't work with any RSPs) are missing out on. This feature is really great mainly for VHF and UHF monitoring and makes your old fashioned scanner receiver obsolete and look really old when you see the immediate long list of frequencies with activities to be checked later. The RSP1A is really a amazing bang for the buck because it comes with really practical filters built in, which give you a good reception in almost any RX situation, ideal while traveling, just leave your preselectors, attenuators and filter boxes, cables and adapters at home and you will not miss anything when using portable antennas. Its enormous frequency coverage makes it special and very versatile. If they could only make it more compact, use a simple metal case by design and waste less space in this huge "empty" case, which seems to be only this big because of marketing reasons, it would be nice in a form factor like the even better but UHF frequency- and bandwidth-limited Airspy HF+Dual Port and HF+Discovery, which are in a similar price range as the RSPdx and RSPduo. These Airspy's are in terms of dynamic and selectivity even better but with the disadvantage of missing out of all frequencies above 260 MHz and a sample bandwidth limitation of max. 768 KHz. (no 70+23cm ham band, no ADS-B, no 400MHz weather balloons, no 430 and 800 MHz telemetry and other cool stuff). But e.g. for serious HF- or FM-BC DXing these mentioned Airspy models are a must have, they are unbeatable in that price range. They use a very new and improved mixing technology as well as A/D converters with a far higher resolution, which only need a slight preselection to remove any remaining images. I am very curious to see comparisons between the RSPdx and Airspy HF+ Discovery on frequencies below 2 MHz, for which the RSPdx is supposed to be optimized. Talking about an RSP with a better form factor and case - there are cheap Chinese RSP1 clones (MSI. SDR on eBay) on the market, which are not much bigger than most RTL-SDRs, come in a metal case and cost half the price of the RSP1A. But they are quite horrible when it comes to noise and preselection (no filters!). Over the entire range from HF to UHF they have usually between 5 and 25 dB worse signal to noise even under ideal lab signal generator only conditions. In the real world (antenna) it gets even worse because they have plenty of issues with imaging. I have no affiliation with the manufacturer of the RSP radios, but I can only recommend to not buy these clones, they are a waste of money, because even a TCXO based RTL-SDR for around 20$ has less imaging problems and gets a better signal to noise than these, which theoretically have a better dynamic range, because of 12 bits instead of 8 but with their poorly designed front end and oscillator it really doesn't buy you anything. I hope this gives viewers a wider angle of view of the most popular options with good community support and an easier decision making to meet their individual radio interests.

[@moglitoashoe9265]

is the rspdx a direct sampling sdr receiver ??????

[@keelieyohara7246]

I have every SDRPlay product except for RSPdx. I am buying it next.

[@tonymcgee1146]

I have an Icom 7300 and how would this improve my station?

[@Laboenligne]

Well, it covers way more frequencies, if fully cover from 100 Hz to 2 GHz, all modes with a scanning function. It also supports 10 MHz spectrum view, but for HF operations only, the IC-7300 is more than enough to operate on ham bands. 73

[@miketarlin9032]

Seems pretty cool although with such wide coverage, resonant antennas alone would either cost a fortune or your yard would look like a data center! Can't really see anything interesting above 902Mhz anyway; plus, coax loss above 800Mhz is severe unless one can afford hardline.

[@cthoadmin7458]

Can the SDRuno software be customised?

[@Laboenligne]

Oh yes.

[@ManuelPinner]

Like Your Product very Good Quality, I have the SDR Play RSP DX, use if for Short Wave and listen to My local Radio Traffic! It be very nice if You can put the Ability to Decode Digital Voice Modes and Video Modes for Digital TV, I also Use SDR Angel Software with this SDR and it Works very Good,

[@mikeydvd1]

Wow. This is so awesome. Being a flex guy. This intrigued me a lot. Very very cool. Thanks for sharing. AA1US

[@Laboenligne]

Thanks Mikey, glad you like the format. 73 Pascal VA2PV

[@larschristensen4677]

Hey pascal , can you show us how you have connected your SRDuno software to your IC7610 i have looked every were on internet , with out any luck, please make a guide , thanks, like your video's and your channel

[@Laboenligne]

Hi Lars, I will try to check it out later. Thanks for watching. 73 Pascal VA2PV

[@bodstrup]

when doing an interview with an interesting person, try not to take over, telling your own tales. A little over the middle of the recording, you talk forever :-)

[@Laboenligne]

Thanks for the tip, usualy I'm alone in my video hihi, can't help it ;-). 73 Pascal VA2PV

[@SEATTLITERON2]

Who would want to put this much time and effort into an ancient technology? All this to listen to so much dribble from the air waves. It makes no sense at all.

[@Laboenligne]

That’s what many people thinks, but this is new technologie, yes it’s more difficult and challenging compare to a cell phone, but this is the behind the scene on how cell works, making it work properly is the point of the hobby as we learn in the process. 73

[@tomperone9338]

Ancient technology? What is it you imagine has replaced it?

[@dondonaldson1684]

Thanks for the excellent discussion and demonstration. VE3NAP
