It's all about the Software

Simon's latest post on the 666/888 makes reference to the SDR requiring a lot of current; I'm wondering just how much? My SDRs reside about 10 ft. away from the PC & I'm using a USB2.0 extension cable with thicker power wires (22 or 24 gauge) to...

RX888 arrived yesterday. Set up was straightforward after downloading Cypress drivers. It worked very nicely with SDRC. I could access 0-30MHz bandwidth but with high CPU usage (>50% on old i7). RX performance (on ham bands) was similar to my Anan...

Does anyone know of a suitable - low-cost - down convertor that could be used with the RX-888? I am specifically looking at the 88 - 108 MHz FM broadcast band.

So far I have found a mixer module on banggood for around £8.50 - £11.50. It would...

For anyone interested, Franco Venturi has just released a new test firmware for the RX-888 on the other forum:

Out of curiosity I renamed it to BBRF103_SE as before, and it works very well in SDRC, with crash-free stop-starts and bandwidth changes...

How do you calibrate the rx-888? Help button is broken. Do you have to be in am mode?

Hi all.
Last night Justin Peng showed via his Twitter flow that he has made a 64 MHz BW update for the RX888 (for HF only, naturally).
Also some other updates are available via links i.e. embedded FX3 FW into dll and three stage gain control for...

Warning I bought a longer 5m lead and it doesn't work. Don't buy this The supplied lead is short but works fine.

Hi Simon,

I just received my RX-888 and tried to use it with latest SDRConsole. As a result, audio is always stuttering and RAM usage is constantly adding up to 20G (!) within a short period of time and thus stopping the complete system, which is...

Seems the Chinese have launched a new SDR from the Dragonfly series. This time its also a 16 bit SDR, but the price is only between €147,32 and €155.64.

Could this be a polished and simplified edition of the older RX-666 and RX-888 models?

New kit for test team members.

Hi.

Maybe someone with solid knowledge about USB3 drivers and HW can give me a hint about how I should proceed with my investigation and hopefully solving of the below described problem.

I had my RX-888 open in order to get +5V from the USB...

Has anyone studied the architecture of the RX888 (or 666 I guess) and concluded what is the likely performance at VHF/UHF? Also LF/VLF?

Question 1:
I guess what I am getting at is what is the likely VHF/UHF performance compared, for example to the...

I just received my RX-888. Since I like to listen to the bands by tuning around I will enjoy exploring a wide swath of spectrum.

I connected it to my wife's I7 laptop since my I5 has difficulty about 4MHz of bandwidth.

I connected my 160Meter...

Hey Simon,

Got my RX-888 up and running. :) If you need a tester I'm happy to offer my services!

I received an RX888 yesterday and hit a problem with SDRC in that it crashes when initially searching for the radio at the Select Radio - Definitions stage; this is on my main PC (AMD R9 3900X / 32GB / RTX2070) under Win7x64. However, the radio runs...

Hi all.

I did some frequency drift measurements on my RX-888 purchased from shenglongsi eBay shop August 22nd and received on September 29th.

I waited for the RX-888 to stabilize in case temperature (+43C at +23C Room Ambient).
I then calibrated...

My new RX888 is showing up as USRP B200 under Other devices.

Device type: Other devices
Manufacturer: Unknown
Location: Port_#0019.Hub_#0001

Device status
The drivers for this device are not installed. (Code 28)
There are no compatible drivers for...

I have just received my RX-888 and am using it on my wife's I7 laptop since my I5 cannot handle more that 4Mhz of bandwidth.

Here is a 16 MHz bandwidth snapshot form the AM broadcast band to 20 meters. The strong signal around 5 Mhz (actually 4.95)...

I was curious to learn how hot the RX-888 would get after an hour of continuous 32 MHz bandwidth operation, so today I did before and after measurements of the outer case.

My upstairs office was quite sunny and warm today, and the ambient...

NBFM 12 dB SINAD level is 0.9 uV from 144 through 450 MHz, +/- 1 dB or so. Funny thing is that optimum sensitivity is achieved with the VHF gain slider set to 15 to 17, anything higher & the sensitivity degrades badly. I have my sig. gen. connected...

This is more or less a mirror of my recent post to io.groups.

My RX-888 just arrived today. Had to download the drivers (actually the whole SDK, which includes the drivers for several OSs) from the Cypress website, as the Win10 drivers don't work...

RX888_ExIo.dll can download here

I am interested to hear opinion from anyone why has both one of the SDR Play receivers and also a RX666 or RX888.

I have an RSP2 Pro. Just wondered if there is any area at all where the RSP2Pro offers any performance advantage over the RX888? At...

I got my RX888 yesterday. Today I tried to use it in SDRC V3.0.25. The software works fine with my RSPdx. For the RX777 I replaced the driver Cypress FX3 Version 1.2.3.20 in the device manager of my W10 to the one I found on this page. When I try to...
