Hi Ron Fascinating and well done. I am still in the process of setting up my uBitx (got to tick off some other projects first), so it's always interesting to read about what this little thing can

Hi, If you disconnect the raduino and power up, does it still go into TX mode? (Just to rule out something on the raduino side holding the TX line high.) -adrian

K3 could be just fine. With power off, the relays are in their receive position as shown the the schematic. The antenna is grounded for your DC ohmmeter by way of T2, via L4,3,2,1, K1 and K2 As per my

Glad you got it to work Dan. That's the beauty of the rig, being able to customize it to your application. Just a question, why not load the latest software on your V3 rig (maybe you made some

Staples does this now

I’m in the editor. This code in tm0 will adjust the white lies, red line and black boarder for each band. I’m programming it for a 5” screen so we’re working with 800x480 resulution. All

Thank You John (vk2eta), I edited the define statements in the ubitx_menu.ino file per your suggestion, it compiled, uploaded and ran perfectly. I reordered about half of the define statements to

This radio kit and case are SOLD. Thank you for your interest. It is going to a good home. Bill, WB4ME

A hack for am recieve 1) disable 12 Mhz CLK 0 ...Software would be best but ...I terminated it into 50 ohms at the raduino...Works but not ideal 2) hooked this circuit to junction of R114/R115

If you're speaking about the circuit I posted, the jfet (j310) is a depletion mode jfet ie. normally ON ...at zero bias on the gate, about .1 ma is flowing (voltage between source and drain = .004

Jens, That's great progress, you know about where the problem is. Sounds like the rig is powering up in transmit mode, not good, you need to follow up on this. I suggest you triple check that you have

Hi Jerry, I have now been able to start with the 'noise injection' test: I first connected the wire to TP21 and could hear noise increase (VOL set to high). This was not much of a surprise because I

Thanks Sam. I’ll try this out today.

I need one of these printed in Black, anybody know where I could get this done? Joel N6ALT

I am dropping the price to $120, plus shipping, which includes insurance. If no one wants it at this price, it stays with me. This is for the complete unaltered kit, plus the complete Amateur Radio

Fill command is fill x,y,w,h. So, if you want to draw a WHITE box across the 'black canvas' just to the spot where your controls are on the right hand side (h0,etc.), you could use fill

Hey, I resemble that remark...yuk yuk yuk. IMHO one of the uBitx's  shortcomings is lack of AM mode, my favorite voice mode. 73 Jack KZ5A

Hi Ted, Joe is actually on the right path. If you look at his pspectrum page pic, he has opened up the vertical lines to extend across the 'black canvas' portion of the page. I looked around and added

Ted, I assume it's this RF Amp from kitsandparts for $12: http://www.partsandkits.com/rfamp1.3.php Not a bad idea if you have a compromise antenna such that you don't hear band noise when the antenna

A quick love note for uBitx ... Just worked Andy VK5MAV/6 with my seven watts. Heard him coming through loud and clear, really excellent receive on this radio. He is a top notch operator and took my
