The new Silphase R1 SDR receiver

27 Replies


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

Photos of the lab599 Discovery TX-500 in the field

2 Replies

Many thanks to SWLing Post contributor, Don (W7SSB), who shares the following photos of the new lab599 Discovery TX-500. Don notes that all of these photos were taken in Russia–where the TX-500 is manufactured–and include a number of Chameleon resonant field antennas.

Thanks for sharing these, Don.  The thin form-factor of the TX-500, paired with a resonant antenna, certainly makes for a lightweight portable field setup!

The lab599 Discovery TX-500 QRP transceiver price and anticipated delivery via HRO

9 Replies

This evening, I discovered that HRO now has the long-awaited lab599 TX-500 transceiver available for purchase on their website.

I had actually placed an order for the radio, but I’ve asked to cancel it because I should have a loaner available for review.

Without a doubt, the TX-500 is one of the most anticipated QRP transceivers this year. Field operators have always wished for a rugged, weather-resistant portable radio and the TX-500 looks like it will fit the bill! Based on some of the videos we’ve seen, it should perform as well.

Click here to check out the TX-500 on the HRO website ($789.95 US at time of posting).

Update: HRO informs me that the lead time, or anticipated delivery is still weeks away.

New Icom IC-705 videos and few answers to your questions

8 Replies

I’ve been getting a number of inquiries from readers lately about the new, yet-to-be-released, Icom IC-705 QRP portable transceiver. Here are a few quick answers to frequent reader questions:

  • “Will you review the IC-705?” Yes, I certainly will. If the loaner unit from Icom has a long lead time, I’ll plan to purchase one from the first production run and may sell it after the review. (Only since I already have *way* too many QRP transceivers!)
  • “When will the IC-705 start shipping to customers?” That’s a tough one to answer and, of course, I have no affiliation with the manufacturer so really can’t comment. As we’ve mentioned before, IC-705 production like other products this year has been delayed due to the Covid-19 pandemic and the impact on supply chains. I do know that Icom hopes to start shipping the IC-705 within the next few months. Availability may vary based on where you live since Icom has regional market headquarters.
  • “Does the IC-705 have an internal ATU?” No, it does not. However, Icom recently announced that they will produce an antenna tuner for the IC-705 with the model number AH-705. There are no details available at time of posting, but we must assume this is an external ATU.
  • “Will it ship with a battery pack, or do we have to buy it separately?” The IC-705 will include a  BP-272 Battery pack, HM-243 Speaker-microphone and OPC-2421 DC power cable.
  • “With a color touch screen display, won’t the IC-705 current drain be too much for operating on a battery?” Since I’m primarily a field operator, this was one of my first questions as well. Turns out, Icom has employ some agressive techniques to make that display as efficient as possible. Check out the promising numbers from their recently-published specifications page:
  • “Will the IC-705 double as a portable shortwave radio broadcast receiver?” The short answer is yes, but we have yet to actually put this general coverage transceiver to the test. What we do know is that the AM bandwidth can be widened to 6 kHz according to the specifications sheet. We also know that its receiver range is 0.030–199.999 and 400.000–470.000. The IC-705 will cover the entire AM broadcast (mediumwave) band and the entire HF/shortwave spectrum with no gaps. How sensitive the IC-705 will be outside the ham radio bands remains to be seen.
  • “Will the IC-705 include the 4 meter band?” I’ve gotten this question from a number of our UK readers. The answer is no. There were conflicting reports early on, but Icom UK posted this message on May 29, 2020 noting: “We regret to inform you that contrary to our earlier messages, the 70MHz (4 Metre) band will not be included in our much anticipated IC-705 QRP SDR transceiver.“

Icom IC-705 Videos

A number of YouTube channels have been posting videos of pre-production IC-705 units in operation. Many thanks to a number of SWLing Post contributors who’ve shared links to these.

A new visitor in the shack: The HobbyPCB IQ32 SDR QRP transceiver

2 Replies

Last week, I took delivery of an IQ32 SDR Transciever on loan from HobbyPCB. The IQ32 has been on the market for a few years now and is a fusion of the HobbyPCB RS-HFIQ and the STM32-SDR.

I’ve been told by the HobbyPCB team that the STM32-SDR was developed a few years ago “when PSK31 was the digital mode du jour and PS2 keyboard roamed the land.” Cool thing is, the team is still updating the radio’s firmware.  Most recently, they expanded the rig’s CW capabilities and re-worked the memory structure and organization based on user feedback.

I see the IQ32 as a collaborative transceiver project and look forward to trying a few QRP PSK-31 contacts in the field with only the transceiver, antenna and a PS2 keyboard. Need to check the shed for that keyboard!

Anyway, should be fun!

I plan to write an article for The Spectrum Monitor about the IQ32, explore how it came about, and point out some of its unique features. It’ll be less a review and more of a tour of this little rig.

For more IQ32 info and specs, visit HobbyPCB online.

Many thanks to SWLing Post contributor, Mike, who writes:

Hi, Tom: Icom Japan have just published a couple videos in Japanese where and enthusiastic JH1CBX takes us on a tour of the new IC-705. Although many of us don’t speak Japanese, it’s easy to understand what she’s talking about as she tours the radio features, functions, and ports. I’ve had an IC-705 on “pre-order” for months now, so I appreciate the preview. Perhaps Icom UK or America will follow-up with some videos as well. Thanks for all you do for the shortwave and ham radio community, Tom. 73, Mike

Thank you Mike! I plan to review the IC-705 and look forward to seeing how well it works in the field.
