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.

Dan spots a rare Squires-Sanders SS-1R receiver on eBay

Many thanks to SWLing Post contributor, Dan Robinson, who writes:

This is only the second Squires-Sanders rig that has appeared on the used market in decades, though it’s the amateur receiver.

The SS-IBS, the receiver pictured in a 1970s Communications Handbook in the shack of Richard Wood, the well-known SWL and linguist, is even rarer:

No new metal building for 2019 Hamvention

CQ Magazine report there will still be tents for some commercial exhibitors at next year’s Dayton Hamvention.

In one of their first acts as leaders of the 2019 Hamvention, General Chairman Jack Gerbs, WB8SCT, and Assistant General Chairman Rick Allnutt, WS8G, announced on August 5th that they had been unable so far “to reach an agreement on a long-term contract (with Greene County officials) where both the Fairgrounds and Hamvention would feel comfortable erecting a new building.”

The announcement was made “in the spirit of being transparent,” they said. Gerbs and Allnut stressed that the overall relationship between the Dayton Amateur Radio Association and Greene County remains excellent and the Hamvention will continue to be held at the fairgrounds in Xenia. They cited improvements made for the 2018 show and promised more for 2019. However, a new commercial exhibits building will not be among them.

The 2019 Dayton Hamvention is scheduled for May 17-19.

I’ll admit: this is disappointing news. I’ve had a table in the tents the past two years at Hamvention. The first year (2017), the tents were pretty dismal–lighting was almost nonexistent and there was serious water intrusion.

This year, DARA obtained much better tents and did a proper job securing the walls and avoiding the drainage areas. Still, water intrusion was an issue. If it rained (and it did) the floors (i.e. asphalt) got wet. Vendors had to keep their inventory off of the floor at all times, else it would get soaked. Since so many products are stored in cardboard boxes, are electronic, and not waterproof, this was a serious issue. I spoke to one of the larger tent vendors who was really upset about the water intrusion and lack of security and vowed not to return unless they could get a proper indoor space.

To please outdoor tent vendors, I believe DARA ought to give discounted pricing for those spaces, increase security, and at least provide crates or pallets to help vendors keep their inventory from contacting the ground and getting soaked.
