Silphase R1 videos and information about power and antenna ports

We’re starting to get a little more info about the recently posted Silphase R1 SDR receiver. At this point, the radio isn’t in production and is obviously only in a prototype stage so there are a lot of question marks–including if it’ll ever come to fruition. The pandemic is obviously not an ideal time to launch and produce a new high-end radio. I, for one, certainly hope they do!

Many thanks to SWLing Post contributor, Mark Hirst asked Silphase about R1 external antenna support and power options. A Silphase representative replied:

“We are constantly redesigning the rear panel receiver Silphase R1, so we
can say for sure that there are 4 connectors – antenna F-type connector,
12.6 V power/charging, RJ-45 and USB”

And thanks to SWLing Post contributor, Paul, who received the following info from Silphase:

The new Silphase R1 SDR receiver


I’ve just learned about a new SDR receiver in development by the Polish company Silphase. It’s called the Silphase R1 and appears to be a stand-alone, high-performance SDR receiver.

What could set this receiver apart from the rest is the:

  • Color backlit 5″ TFT touch screen display
  • Magnesium alloy body/chassis
  • USB out for recording and native logging
  • Record to internal “flash memory” (unclear if audio and/or spectrum)
  • Four internal speakers
  • 12.6V 12000 mAh, internal battery
  • IP55 rating for water/dust protection
  • The price is $1199/€1099 with no expected availability date at time of posting
  • Click here to download the PDF product brochure.

The receiver is portable and will measure 11.25×4.3×2.2in (285×110×55mm). Looks like the screen will be 5″ which should allow for a detailed spectrum viewing area (for comparison, the Icom IC-7300 TFT display is 4.3″)

Siphase is a new company based in Poland and they claim they also plan to eventually produce transceivers:

“At the end of 2020 we will introduce a 25W transceiver in the same form factor powered by an internal battery, and a bit little later a 100W transceiver in the same form factor also powered by an internal battery.”

The Silphase product page has a complete list of specifications, but here are some worth noting:

  • Frequency coverage RX 0.1–30MHz
  • Frequency resolution 1Hz
  • Frequency steps 1Hz to 1KHz
  • Dual VFO
  • Direct sampling 16bit high speed 122 M/s ADC
  • Modes: CW, SSB, AM, FM
  • Sensitivity 1.8–29.999MHz, SSB/CW: (BW: 2.4kHz at 10dB S/N) – 132 dBm, 0.06?V
  • 20dB LNA
  • Spurious and image rejection >90 dBm
  • Clipping level -3dBm
  • DSP (various filters, adaptive noise reduction, automatic notch filter, notch blanker, adjustable filters (0-1KHz HPF,0.5-6KHZ LPF, 50Hz step, etc.)
  • AGC (slow, medium, fast)
  • Main filter sharpness Factor 1.05 and lower
  • Audio recorder (use the internal flash memory or USB 16GB external flash memory)
  • Virtual USB audio card for OS update
  • Ham radio hardware log
  • OS QNX (“UNIX-like” real time operating system)
  • Telescopic antenna with F connector
  • Main optical encoder and four multifunction encoders
  • 6 input modes buttons (attenuators, adjustable filters, AGC, NB, auto notch filter, NR)
  • Power supply requirement 12.6 DC ±15%
  • Power consumption RX 0.6 A typical
  • Battery 12000 mAh, 12.6V (3×3.7V/12000 mAh)
  • Operating time 20 Hours
  • Operating temperature range –10C to +60C; 14F to 140F
  • Frequency stability Less than ±0.2ppm (–10?C to +60?C; 14?F to 140?F)
  • Dimensions (W×H×D) 285×110×55mm; 11.25×4.3×2.2in
  • Weight (approximately) 1.8kg; 4 lbs
  • Magnesium alloy body, IP55 (in future IP 67)
  • “Expected Operational Lifetime 30 Years” With One Year Warranty – Additional Warranty
  • Made in EU

As I learn more about this receiver and the company producing it, I’ll post updates with the tag: Silphase R1
