Adding discrete diodes and a pot for the modulator to better suppress the carrier has been discussed here. I haven't heard of anybody who has done this and decided it was worth the trouble. Being an

Hi, In theory shouldn't the mixer attached to CLK #0 be balanced and suppress the carrier? In that case the filters only need to suppress the unwanted sideband, not the carrier. The matched mixer

Also check your local Junior College/Universities EE or physics departments. Even some high schools have SA these days. Phone companies and cable TV companies may also have equipment. Jack, W8TEE

Ben, The board should work on a V5 Board. Where we tap for attenuation of loud signals, and where we draw our bias to adjust signal level from is still equivalent between V4 and V5. The only thing

Curt Indeed agreed. My V4 is only marginally out of spec on 20m using CW tests. The V5 seemed OK on all bands on CW but at the moment is picking up a lot more broadcast signals off the same antenna.

Michael I anticipate that a reliable cure for spurious will emerge soon for v3 and v4, and may apply for v5. Its understood that most of us don't possess a spectrum analyzer. My local club is building

...and don't forget to remove the microSD card after you've loaded the new firmware like I did, otherwise it won't work :)73 de Mike

Mike Where are you located. I am sure there is a school in the area or a ham club that could help with test gear. Any Spectrum Analyser test tool. Even an sdr with a down converter and proper

To Peter, hi Peter i received the inductors, thanks a lot. 73 Uwe DF1UB

https://youtu.be/hhQkF18Vpho This video demonstrates the process step by step. I had to pause the video and look closely to see where to connect the wires.

I have to admit I do talk to it when I am working on it. But I always finish ,or at least as much as possible, finish what I start. Not having any real RF test gear I wont know if I am “legal” or

I recently assembled a uBitx and would like to add a Nextion Enhanced 2.8 screen.? The instructions that I have found seem to be way above me. when it comes to finding, downloading and installing the

Dave Just take out the circuit board and cut through the traces around the two switches. Solder in two resistors and jumper the other end of the switches together. On mine I covered them with shrink

Sweetness!!

Agreed all 'round. Long-term the paddle is best. Operates with a roll of the wrist! Just getting into Ham Radio(50-odd years ago), my Morse tutor was George Studd, ZL2AFZ, a DX Ranger. A visit to his

Dear Peter, Hi again, I will take those off you hands.I assume the PayPal is as for the ubitx I bought yesterday.please just confirm and I will PayPal you. Many thx. 73. Ian Reeve M0IDR Get Outlook

As you may know, I've sold my V4 ubitx - shaking hands and poor eyesight are not conducive to working with smd's! I've still got quite a few SMD inductors (about 200 ) for the 45Mhz filter mod, so if

Hi Dave, like the idea of a mouse,any chance of a look please.regards Dave.

Er ...That would? probably have been me ...Photos attached ..Note new Q11/Q31 have to be mounted "upside down" and rotated to get the pins lined up as per photo ...Also need to change R14-R34 from

Mike I think some frustration indeed but I trust you will indeed get this unit working to your expectation and within FCC specs. What I would suggest is you work on that with as few additions as
