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:. QSX is still in development!

The above list is subject to change. We don't have an exact date, it depends how long it takes to finish all the above features and manufacture it etc. Any updates will be published on this page. Update Aug I know this is taking longer than expected, but there are still a number of details to sort out. I do not want to release it before it is properly ready. It needs to work perfectly first.

It's a huge complex project Update Jan Development continues, progress is being made but there are a lot of details to take care of.

Still no update on projected completion dates yet.

We aren't taking pre-orders at this time. Previous experience has shown that taking pre-orders before the development is finished adds to the stress and administration workload. The effort is better spent focusing on finishing the development!

The full set of features wasn't completed in time for the summercamp but will be made available to the attendees over the coming weeks as it is developed. Email us. But questions will be answered only if they are not already handled by this FAQ page. This way, we can concentrate on the hard work of finishing the development.

Four self-adhesive rubber feet will be supplied for the bottom and these would add 5mm to the bottom if installed.

Finally at the rear, the heatsink protrudes 25mm from the rear panel as shown in the photos. You may need to make allowance for RF, Power etc connectors at the rear panel too, this will depend on your own installation. We aren't sure exactly yet. These are ballpark figures and subject to change. How will firmware updates be installed? QSX firmware updates will always be free for life. The firmware update procedure is very simple. No special hardware or software is required!SDR transceivers have become more popular and the development has been encouraged by many radio amateurs and somewhat surprisingly, not yet shown by the old guys, Kenwood, Icom and Yaesu.

The SDR transceivers that have been introduced by other companies, Flex Radio Systems in particular, provide even more technical performance at a lower price than standards rigs. However, they have been depending on PC to be used.

Elecraft has become a very respected name for various qrp transceiver kits, available as pre-built too, as well as the K3, and other accessories too. It has a desktop design, as compared with the typical style as of the Yaesu FT The circuits that cannot be replaced with software, of course, is for the drive and final amplifier, antenna front end, microphone preamp, speaker amplifier output.


It will definitely change it but probably not take over. Compare with audio which uses a lot less frequency than RF. Digital electronics could therefore be implemented earlier in audio equipment, and was more and more introduced in the 80s. Looking at digital studio recording equipmen, there were digital units that emulated analog equipment and did more. However, in the early digital era, mostly buttons were used and one or two controls were used to control each parameter, either buttons or with a value knob too.

A couple of years later, analog and tube electronics became again popular. Since older analog equipment had used more controls and potentiometers, the manufacturers then included more of analog-feel-knobs, analog emulation in the digital equipment, and even tube sound emulation. It was different for digital audio equipment because it was before PCs were common. Of course there were some of interface with midi, with Atari computers and it was used by home recording musicians.

When PCs became more common, then it was used for audio too. For a while PCs have been used for radio and still will, but from now on, there will be more SDR transceivers without the always need for PC. Yes probably. SDR RF equipment is likely to become cheaper with today's competition. In a couple of years, SDR transceivers that can be used without a PC will become more common and then, with potentiometer controls which only the KX3 and the Cube have today.

These should become cheaper as well, because of the fewer parts. FlexRadio Systems. SDR Cube. The K3 is larger transceiver with many features, making it among the best rated rigs. This is a definite move in the ham radio industry. It's overall performance is then accomplished with DSP which makes it possible to define the characteristics by means of software.

Hence, as the software will be upgradeable, its performance will be improved as well. Furthermore, a number of other features are included such as dual watch and data modes.

A DSP provides noise reduction, noise blanker, auto-notch as well as stereo audio effects with an 8-band audio equalizer.

It is adapted also for mobile use and it has taken quite a long time to develop.

Info will be added gradually and eventually the first index page will also be as this one. Qrp radio means that it is possible to use equipment that you have built yourself, either by your own construction, after a kit, or both. It offers great opportunities to learn different types of electronics in different applications such as for radio frequency, low frequency, audio and signal processing.

All this relates to many other different sciences in other fields of physics and even biology. The hearing is an example of where there is an advanced signal processing within the auditory system of the ears and the brain. Knowledge there can be used in the design of analog or digital sound processing.

There are certainly many other areas of electronics or other scientific areas where you can learn a lot. But we who have once become interested in radio do not get rid of the interest so easily! I have not included the simplest kits with a fixed frequency.

The transceivers and transceiver kits below should be in production. I have not included chinese counterfeit goods when it may be so. Such garbage should definitely be avoided. As an exampe, look at this chinese counterfeit company page. The sdr transceivers on that page have been featured on many sites and even at eham. Share this information about these counterfeit ham radio equipment to other radio amateurs as not everyone knows about it. Also, there are some pages with a lot of german qrp kits, herehere and here.

I found pages for four kits with manual links, Blue cool radio - Eham. Sparrow Mosquita - Eham. Unless they have a lot of kits which I doubt. Maybe I send an email to ask them if these kits are available- If they are, I ask for more information. Breadboard Radio.
