The Hermes-Lite SDR: an open source HF transceiver based on a broadband modem chip

Many thanks to SWLing Post contributor, Pete Eaton, who writes:

Don’t know if you are familiar with this project, a full blown 5 watt HF SDR Transceiver for less than $300!

No sound cards, DUC/DDC architecture.

Here’s the project description by Steve Haynal via YouTube:

The Hermes-Lite is a low-cost direct down/up conversion software defined amateur radio HF transceiver based on a broadband modem chip and the Hermes SDR project. It is entirely open source and open hardware, including the tools used for design and fabrication files. Over 100 Hermes-Lite 2.0 units have been successfully built.

The FOSSi Foundation is proud to announce Latch-Up, a conference dedicated to free and open source silicon to be held over the weekend of May 4th and 5th in Portland, Oregon, USA. Latch-Up: a weekend of presentations and networking for the open source digital design community, much like its European sister conference ORConf. Produced by NDV.

Fascinating! Thank you for sharing, Pete!

N6QW introduces the Sudden QRP SSB Transceiver

Many thanks to SWLing Post contributor, Pete Eaton (WB9FLW), who writes:

From the fertile mind of QRP Hall Of Fame Pete N6QW comes a new Radio Project, the Sudden QRP SSB Transceiver. If you have never Scratch Built such a Rig and would like to N6QW’s latest offering deserves close inspection.

Using only readily available (and cheap) components (and few of them) one can build a Full Blown SSB Transceiver for either 40 or 20 meters. The Radio’s Design will be featured in 2 installments of GQRP’s Sprat Magazine. The 1st being in the Fall issue (Receiver/LO) and the second part with come in the Spring 2019 issue (Transmitter).

Pete is also providing extensive documentation on his Website:

http://www.n6qw.com/Sudden.html

One use for the Rig is on the Digital Modes, to that end he has design a simple Digital Adapter (which is also described on n6qw.com). One possibility is for a dedicated FT8 Transceiver!

Even if you do not intend to build the Rig take a moment to check out his Web Page. There you will find a wealth of information on designing and building such Transceivers.

(not to be confused with Pete N6QW 🙂

Thanks for the tip, Pete! How exciting! This looks like an innovative little rig and I love the concept of only using accessible components–in the end, that will give this little rig some longevity.

QRP Labs Announces The QSX Transceiver

The QSX Transceiver

Many thanks to SWLing Post contributor, Pete Eaton (WB9FLW), who writes:

QRP Labs has just announced the QSX an All-Band All-Mode Transceiver Kit that should be available later this year. The Target price for the 10 Band Model is $150, also available will be a 40 Meter version for $75.00.

Details from QRP Labs:

QSX (QRP Labs SSB Xcvr) is a 40m SSB transceiver with 10-band (160m-10m) and enclosure options. The kit inherits all the functionality of the famous QCX single-band CW transceiver kit but adds SSB, AM, FM, PSK31 and RTTY. This will be the lowest cost all-HF radio available but also high performance and packed with features. These are the planned features of QSX:

  • Software Defined Radio (SDR) technology with standalone Digital Signal Processing (DSP), no PC required
  • Very high performance 24-bit Analog to Digital Converter (ADC) and 24-bit Digital to Analog Converter (DAC)
  • 40m (single band) or 160-10m (10-band, including 60m) versions available
  • Modes: SSB, CW, AM, FM, PSK31, RTTY, WSPR beacon
  • Power output: 10W from 13.8V supply (power output is adjustable by the firmware)
  • Single power supply needed, 12V to 14V
  • USB host interface and connector, for USB keyboard to allow PC-less operation on PSK31 and RTTY
  • USB device interface and connector, for PC CAT Control
  • QSX can appear to a PC as a high performance 24-bit USB sound card and radio – for digital modes from a PC e.g. FT8, either demodulated or as I-Q for PC SDR programs
  • Built-in CW IAMBIC keyer (or straight keying also possible) with raised-cosine key-envelope shaping
  • DSP features (selectable sharp filters, AGC, Speech Compression, Noise Reduction etc.)
  • Dual microphone inputs (mobile phone headset with VOX, or RJ45 connector for Kenwood/Yaesu mics)
  • Dual VFO (A/B/Split), frequency and message memories
  • Through-hole assembly only
  • Built-in test equipment features for alignment, debugging and general purpose use
  • Detailed assembly manual
  • Macro facility for user defined sequences of operations, or redefinition of controls
  • Front panel: 16 x 2 LCD (yellow/green backlight), 2 rotary encoders, 4 buttons, mic/earphones socket
  • Soft-power on/off switch, the radio saves its state automatically on switch off, so that it starts up in the same state next time
  • Free firmware updates for life, very simple firmware update procedure via a USB memory stic

QSX is still in development! The above list is subject to change. The following is a FAQ with information about QSX.

The uBITX Transceiver: Pricing and more details

Many thanks to SWLing Post contributor, Pete Eaton (WB9FLW), who shares pricing and additional information about the uBITX general coverage QRP transceiver:

Here are the details, if purchased before Christmas $109 delivered!

http://www.hfsignals.com/

From uBITX creator, Ashhar Farhan:

1. The ubitx is now available for sale, for $109 dollars (includes the shipping), but only until Christmas. *After Christmas, the price will increase to $129 dollars. for this initial batch, a few ham volunteers and I pitched in to sort the crystals, test the coils, tune-up and box these initial kits, we won’t be able to do that any more. we will have to hire more people (which is not a bad thing) and get them to do it.

2. The ubitx is on sale at hfsignals.com, not hfsigs.com. it is easier to remember. we will soon point hfsigs.com to the new website as well. The new site is in wordpress, that means that we can have volunteers writing and updating it rather than waiting for me to hand code the content in html and vi editor.

3. We need help with proof reading the web content.* If you find any typos, please mail me on farhanbox@gmail.com address (not the bitx20 list),

These apart, the early buyers must be aware that they are beta users of sorts, the firmware will sure get updated. i hope there won’t be any revisions of the PCB.

Pete adds:

Just as an aside the original price of the Heathkit HW-8 was $139.95 (in 1970 dollars) and it became a QRP Classic. The uBITX may become  one as well and like the HW-8 there will be (and already are) all sorts of mods/additions one will be able to do. The uBITX is 10 dollars cheaper (after 12/25) works 80-10 M, does SSB in addition to CW, and is a Superhet to boot!

Farhan your hit this one out of the Ballpark!

Very cool, Pete!  I am very tempted to purchase the uBITX transceiver before Christmas and have it delivered via DHL service.  The only thing holding me back is simply the amount of projects I have on my table at the moment! $109 is an incredibly low price for a full-fledged QRP transceiver!

I’m absolutely amazed that it is also has a general coverage receiver.  Perhaps the uBITX could serve the SWL as well as the ham radio operator?  I suppose we shall soon find out!

Please comment if you plan to or have purchased the uBITX. We’d love your feedback!
