I did that back-to-back test of two myantennas.com matchboxes. I'd say they are plenty efficient for my purposes from 3.5 to 30 mhz. My 2 year old matchbox is referred to here as xfmrA. Text on the

dkuk I want to thank you for pointing out this error on ubitx.net. I have fixed this temporarily by removing both the photos from that page and by deleting the reference to

Hi!, I have been scratch building a uBitx and had been experimenting with the 12 MHz QER filter. I have noted few things and adopted some from various postings on group. 1) With the set of xtals that

The front panel stereo socket board wiring layout for universal case for ubitx has been published. 8 pin relimate female to female connectors are used for digital and analogue connectors on ubitx

Ryan, Hints sent to your youtube page based on KNOWN performance of similar Renesas mosfet in parallel operation for bringing power up to region 14W RF out. Timothy E. Fidler : Engineer BE Mech(1)

Arggh an assumption re-arranged makes an Ass out of you and me.!!!. I thought Ashar F would have gone done the merry conventional way with pulling the BFO to get sb flip .. so next time you want

OK, we have a lot of misunderstanding here... uBitx. If the master osc is not set on frequency everything else is likely to be off frequency and work poorly. The filter is ladder filter (not a Cohn)

Allison, Thanks for all the suggestions! Regarding your points: I do not have a star washer at the coax connector on the uBITX. Nor do I have star washers under the mounting posts. I'll give that

Both if it’s easy?😳 72 Scott ka9p Make something good happen!

IRF510 at 20M is not an issue or even working hard. I have several radios that really work on that band using that critter. Bitx20 (V0) from the early years, uBitxV3, Slopbucket 20 a Kd1JV design.

Terry, I did this. I also changed the PA FET for a RD15HVF1 because it worked a lot better on 20m than the IRF510. Info on both

Sorry . brain fade.. invert the answer. Jack clearly had to set the BFO way Low to select USB so it would pass the Cohn filter which appears to have its passband low on 12.0000 but the issue still

Jack it is not a problem - it's FEATURE ! But if you were setting this up on a system which has to swap USB/LSB between 40 m and 20m, which yours will since you are uBitx .. I suggest you need to

OH,, ok..thanks. Kevin

Its for the Real time clock. its not needed for now. if someone implements it in the firmware then it could be used.

hi guys, what is the battery holder for on the nextion display ?? something we need ? kevin rea lancaster, calif. k6rea

never mind.. i just received it today. thanks, kevin rea

Hi Again. Would folks prefer the Pot to adgjust the ACG or the Jumpers as per Kees' boards? I am in 2 minds about it,,, 73 Nick. VK4PLN

I was wondering how close those fires were. The rule here if if you smell the smoke its too close. Take care. Keep building! Allison

Hi Allison, I need to redeploy that antenna, I have the feed point at the same level as the far end and the wrong coax on it, so I know it's my fault it doesn't perform any better than it does. I
