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

HI Again, Just PCB boards. I am still designing them, and awaiting a new callsign too, so, I am hopin in the next week or so to get all my current board designs finalised and then place and

Hello, do you know if you have possibly shipped my unit? Kevin Rea

Nick, would like to obtain 2-3 of your AGC PCB boards. If you are planning a kit with parts, I can wait for that too. - Rich WB2GXM

Thanks all for sugestions.... Rich, This one is the same as Kees' in operation: RF I was also wotking on an AF (VK3YE board) version for those who would prefer that... 73 Nick.

Nick, it is my understanding that Kees' AGC kit works of the RF (IF) stage, whereas your kit works off the audio stage? Thanks - Rich WB2GXM

Chuck, I'd ague against more than an octave for another reason, pattern. That and for 12, 10M and 6M up antennas get small enough there are a a whole other set possible improvements. I'd think if

Yes same problem here. Philip.

I know this is an old thread, but I wanted to say thank you to everyone involved. My BFO was set to 11.995.250. If I went 1 kHz away people were loud by tinny. If I went on frequency, they were

I also "cheated", using Jim W0EB's breakout boards for the sockets and encoder. They're silkscreened with labels for tip, ring, sleeve, so I didn't wire it to "pin 2", I wired it to what is marked as
