As Tom, WB6B suggests, an important reason for displaying the TX frequency in CW modes is that you need to know that when you hit that key that you are transmitting in-band. It is more important to

Hi Rob Doing these mods this evening. Much appreciated Howard's parts. For the tee pee - let me know how you did it. I am going to gently put the solder iron on right side and try to lift it as soon

One feature I find really useful is the ability for the unit to "beep" when doing continuity checks. Without that feature, I seem to lose my test points when I go to look at the meter's display. With

Thank you for important information. I made the same mistake. Nextion comes with a USB Pin board in the box. I was able to find $ 14 including shipping costs in Aliexpress. Ian KD8CEC 2018-06-15 16:37

I just ordered one and the model number starts with NX paid 16.22 with 1.99 shipping. Comes from China so have to be a bit patient to if it will work or not. About 2-3 weeks of patience ;) John KG5WJQ

I purchased what appeared to be a Nextion display according to the description, off ebay recently. Cost was $12. It arrived ok but does not work. The Nextion editor warns that displays with the

Something has shorted. take out the PA power line and check? - f

Was in middle of wspr transmission. Radio went dark. Power source checks out good. When cycle off and on, display just slightly flashes. Display and raduino work fine with usb to computer. What

My code is different than most others in that there is an explicit CW mode that you select within the menu. Without an explicit CW mode (just hit the key to send CW, hit the PTT to send SSB), the

That's the same Centech brand as the red rectangular cheapies form Harbor Freight. Pretty much the same functionality. And I'd guess the same stuff inside. The primary differences I see is that this

On the CEC firmware, and the original factory firmware when you use the PTT for SSB the transmit frequency is what is shown on the display. When you key the transmitter with the CW key the firmware

I'm not sure I would recommend trying to replicate all the ACV/DCV/Ohms/Amps/mAmps ranges of a $1 Centek DVM from Harbor Freight. But instead of spending the extra $11 bucks on a DVM with a

I'm not sure what you mean about shifting the BFO. The BFO has nothing to do with transmit. On receive, it can remain exactly where it was for SSB operation. And no idea what all the other software

I pick one up whenever they have the "fee" coupon in the paper or email. Worth it just for the battery!.

I'm another fan of the Harbor Freight cheep/free DVM. I honestly don't know how many I have as they are so cheap and handy I keep them all over the place. If the zombie apocalypse comes I will stay

I too have three chinese voms of a make called mastek. They work pretty well for my needs. They cost me about two dollars each. - f

For most anything you'll do with the ubitx you don't need an expensive desk meter. this

Do you have an swr meter that shows forward power? Does it flcker when you speak into the mic? The mic amp in the ubitx expects to be fed from a high-output electret mic. Is your Astatic mic an
