QRP Labs is now selling a new feature-packed, single-band 5W CW transceiver kit for $49. I ordered a 40m one from the first batch, which quickly sold out. The next batch will be ready in September. I think they're going to sell a ton of these babies.

Thanks for the heads up!  Looks like a really slick kit.  I'll have to get in line for the 20M kit.

2nd batch already sold out, most of next batch accounted for as pre-orders!

Myself and a colleague have a pair on pre-order

Hans knows his stuff and his kits are always feature packed (I run one of his U3S beacons with relay unit and GPS on WSPR), and they get regularly improved through firmware updates. The quality is great, and such simple but often overlooked features like extra board holes for off board mounting controls are provided (at 0.1" pitch so you can use SIL connectors). An amazing thing with this kit is that the test gear to align it is built in! It also works as a WSPR or CW beacon, can take a GPS input to calibrate frequency (and set locator and time for WSPR), inbuilt keyer, CW decoder that works in Tx and Rx, or can be used for practice!

Ive already enquired about WSPR receive capability, but this would need to bypass the CW filter and also some firmware changes, but if enough people think its a useful idea Hans will probably build it into a future firmware!

I can foresee a future multiband version!

I've ordered one for 60 metres because I don't have a rig for that band.  However, I'm intrigued about the WSPR functionality, so I modified my order to include his GPS receiver.  I hope Hans updates the firmware so 6 digit grid squares can be used - the manual currently indicates that only a 4 digit grid square can be inputted.

To that end, can someone point me to a cheap method of updating the firmware for this rig?  I would ask Hans, but I suspect he is QRL filling his orders.

Hans has stated on the QRP-L list that he will not make any of the code public. I don't know how upgrades will work, likely an IC swap.

He does make firmware updates available on his website for the Ultimate 3S, which is different than making the code public...

Then it's in the realm of possibility it'll use the same method as the U3S, since both use the same ATMEL MCU.

I'd like to know how difficult it is to mount this PCB inside a case with those electrolytic caps sticking up.

I recently bought two frequency counters with the same design and mounting them in a case is a nightmare and they don't have the tall caps in the way.  However it is necessary to create access holes for the controls which is also difficult with the readout on the same plane.

I believe what you think are electrolytic caps,are the encoder knob and gain knob.

Here's a very descriptive video of IZ7VHF assembling his QCX:

I'm number 577 for a 40 meter kit.  Does anyone know where the delivery schedule is now up to? Cool
