Robert talks uBITX and navigating the world of used radio gear

Robert’s uBITX QRP transceiver kit with fire red chassis.

Many thanks to SWLing Post contributor, Robert Gulley (AK3Q), who shares the following announcement from his blog All Things Radio:

I have posted two new articles in the Reviews and How-Tos section. These were both previously published in The Spectrum Monitor magazine earlier this year.

The first article deals with buying used and new equipment, while the other article is a review of the uBITX QRP transceiver. Thanks go to Ken Reitz for graciously allowing these to be posted after their initial publication!

Many thanks for sharing, Robert!

Readers, I highly recommend both of these articles.  In his used equipment guide, Robert makes practical suggestions for navigating the world of pre-owned radio gear and shares some important tips. His uBITX QRP Transceiver article is essential reading for anyone who has considered building this incredibly affordable kit.

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!

Pete reports new developments with the uBITX transceiver

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

Last March, Ashhar Farhan (VU2ESE) the designer of the very popular BITX20 and BITX40 series of mono-band HF Transceivers announced a new low cost rig called the uBITX (micro BITX) a full blown 80-10m 10 Watt SSB/CW Transceiver. Now comes word that after many months of very hard development work by Ashhar this much anticipated Rig will soon be available.

For those not familiar with the project this is *not* a kit, rather like its sibling (the BITX40) it consists of two assembled and tested Circuit Boards. The RF board measures 5.5 x 6 inches and a second small plug in daughter card that takes care of the digital portion of the design including the 2X16 LCD, Arduino Nano, and Si5351 which are used in the VFO.

Add a cabinet, knobs, and connectors and you have a full blown HF Rig! An added plus is that except for the Gerber PCB files everything else (including the firmware) is Open Sourced!

The original description can be found here:

Farhan has just released the Firmware, Schematics, and Wiring Diagram for the production version on GitHub

Arduino Sketch:

RF Board Schematic:

Wiring Diagram:

https://github.com/afarhan/ubitx/blob/e481ea2a2457fc4e7be7a6a4bc9a0fba12bf2cde/ubitx_wiring.png

Farhan has a social conscience as well giving several local ladies much needed employment for final assembly and checkout of the Rigs.

There are still a few final tweaks being done to the design so pricing is still to be determined. But if it’s offered at a similar price point as his earlier Transceivers it should sell like hotcakes!

Wow!  Amazing project!  Thanks for the tip and updates, Pete!
