Yes build it stock first and get it working then do the updates/mods. This will make it easier troubleshooting anything that may be wrong. Skip Davis, NC9O

I just received my kit in the mail. I also have a Nextion 3.2e... do you think I just build it all stock first and then do the mods such as the screen ? Kevin

Just finished my first ubitx v4 build and things are not working as expected...Thanks first of all for any and all help. My main symptom is that on power up the display is showing a string of blocks

do you have gerbers for this project to have the board printed and a bom file ?

by the way,, the colors specified in my drawing are the ones from the Baofeng microphone, i opened it up and pinned it out with an ohm meter. kevin

The "dB SPL" gives the Pascal part of 1V/Pascal, but it does not specify the 1V part. 94 dB SPL means 94 dB above the reference sound pressure level of 20 uPa, where 20 uPa is around the bottom

So I would need a 70MHz buffer board for this? Mike AI4NS

Guess I should have watched your video first as you said everything I just said:-( Joel N6ALT

I built and installed the Kees AGC kit yesterday but dang thing would not work.? Waited until today to check it out.? A close look at the board showed that every component was soldered properly with

Thanks peter, Leon at ozqrp puts these into all his rigs. I find them to be useful tools to show power output and sufficient SSB modulation. Joel N6ALT

William, you could consider the road that SM0JZT has taken. He installed a G4HUP buffer amplifier and uses an RTL-SDR dongle externally. This gives you the best of worlds - a low-cost transmitter and

Just to throw in another way of specifying microphoen sensitivities . 1V/Pascal is equal to 94 dB SPL.? So you may see either terms when looking at mic specs. Greg K1YW

Mine did that, too, because the current draw was too much for the PS, and the PS turned itself off and back and on.? That can happen (at least in my case) on lower bands with a bad antenna mismatch.

Sadly based on the data sheet I got some MPSH10s and as reported they didn't perform as expected. The devices I found worked better for me are: 2n2222A(to18), I tried PN2222 and they?produced less

You might want to check the power supply too. If something in it died, you might be getting ac on the power lead which could cause this symptom.

Mucking with RV1 could easily and quickly blow the IRF510. Whenever adjusting RV1 (the IRF510 gate bias voltage), you should be monitoring? the drain current into the IRF510 (12v into PA-PWR1) with

Yes, low output when speaking or whistling into mic. Power wiring correct AFAIK. RV 1 set at about 30% on arrival.? Adjusting to full CCW raises draw to about 1.6 A on PTT, with no change when using
