Furlough 40 SSB Transceiver Project #homebrew


Dean Souleles
 

Hi all -

Not a BITX but perhaps a cousin ...



This is a 100% homebrew project that I recommend form Pete, N6QW's SimpleSSB design.  Only 9 transistors across 9 modules.  This was my first ever transceiver project and only my second project ever - after a Michigan Mighty Mite 7 component crystal controlled CW transmitter than I made in half a day last December.  Here is the first transceiver demonstration of my "Furlough 40" 100% homebrew 40 meter transceiver.

If I can do it, you can too!


Here is the blog post with a video of the first QSO...

Fabulous, Dean!
I like that you have split it up into blocks that you can snap out and replace with other blocks. Good stuff. Pete is a meticulous builder and his circuits are fail proof.

Totally agree. I'm a big fan of Pete Juliano, too, and follow his work as much as I can. He has an SDR project that he's working on that looks pretty neat! Man...wish I wasn't such a dunderhead when it comes to EE stuff, I really admire those who have that talent.

Jack, his simpleceiver as a Rx is astonishingly fine. Please try during this time. Insread of 2 pcs of j310 forming dual gate, we can use bf998 and it simplifies . 
All thest please.

Dean's lovely work hints at the artist within. FYI he is a accomplished photographer with a keen eye. His Furlough 40 has great lines and a hint of  elegance.

I'm humbled and thrilled to note my franken-uBITX's great honor as first substantive QSO with the Furlough 40. The audio was solid with easy copy. 

While the distance is not extraordinary, the accomplishment is. 

DIY to DIY, kit to kit, verve to verve. 

Well done Dean!

Farhan -

Thanks for the nice note.  Pete's circuits are better than fool proof - they are Dean-proof - and that is something special.

Don,

Thank you for the QSO and the recording of the audio!  Always happy to QSO with a Franken-uBitX or any other kind!

For folks that haven't followed - KM4UDX regularly tops the WSPR leader board with his uBitX - and I'm guessing his is the only uBitX on earth with an integrated cell phone charger.

Hi all -

I realized I didn't send the correct link to the blog:

Please take a look and listen to the QSO.

New blog post - Furlough 40 Hears the World...

My overnight receive experiment with WSPR.  Sneak preview - I copied Australia and New Zealand from Northern Virginia.

To quote Farhan: "Pete's circuits are fool proof"

And I'm the fool that proved it.

This receiver rocks.  Now I am turning to tuning up the transmit side to get a little closer to Pete 5 watt spec. Peaking 2-3 right now and making contacts.

New blog post - Getting Control of the Furlough 40

I got tired of dangling wires and added a control panel.  The blog gives the details.   One thing that uBitx builders might want to consider is the addtion of the tune tone function.  This is Pete, N6QW's design that adds a MOX switch to put the rig into transmit, and a momentary push button to generate a 10 second 988Hz 1/2 duty cycle tone directly into the mic input.  It is great for tune up - or as a built-in signal generator for testing and evaluating the transmit chain stages.

Please follow and share the blog if you find it interesting - and give me feedback!

New blog post and video -

I added the FT857d CAT control library from Pavel Milanes (CO7WT) to the control sketch.  It was pleasantly easy to integrate.
