Iz with these numbers I would speak softer into the microphone and be just fine. important to see if they correspond to 'full' output power, if so I think most of us would be thrilled with them.

I guess it could have been worse, I could have types 50MV :-) This is a v3 that I finally got around to playing with a couple of months ago. It had been in the project

Raj, ok mni tnx for your reply :-) Farhan, also mni tnx for your reply :-) Okay, that'll be the first thing I'll check. But I didn't made any changes before - the drive pot is untouched so far;-) 73,

John visibility appreciated. it should behave like most v4's. here is what I suggest -- take some CW data. as its a different path, we found in measuring dozens of rigs that we tend to get

uBitX complete with V3 board, original in the box, untouched, unmodified kit, including the original V3 board, unmodified, and all components that shipped with the kit. Also included a complete

Here is a way to improvement the audio on the uBitx V5, connect a 10 micro F cap to the LM386 + to pin1 - to pin 8. solder to C75. This will give a bit more gain, and bass. Philip G7JUR

is it possible to buy a uBitx without the Raduino? -- 72 and God bless KD4EPG

No, but raduinos posted for sale here have moved very quickly. -- www.bitxmap.com

I have this issue too, when The volume is down there is a buzz. It goes away a little when i turn volume half way, then comes back when i turn volume to max. Joe KD2NFC

Bug spray?

I’m gonna try a resistor and cap mentioned in this post first, but I will try the bug spray if it don’t work. :) https://groups.io/g/BITX20/message/64399 Joe

Dennis Indeed, you will bless someone with that raduino. Also, good idea to test the rig with it before moving to a more complex display. Curt

welp that worked, no more bug, I mean buzz. I used a 1000uf 35v and a 10ohm, its all I had on hand. Gosh I love electronics :) no bugs were harmed with this repair. 73 Joe KD2NFC

Thanks again Jerry. Those were DC voltages as measured by an auto-ranging Chinese DVM. The LCD display has blackened on my good volt meter. I do have an oscilloscope, but just haven't had enough

Adding Philip's 10uF cap across the LM386 pins 1 and 8 on the uBitx v5 looks like a very good idea. This can either replace the stock 1uF cap at C75, or be placed in parallel with it. This may also

Shielded audio wires always work ...(in lieu of spray ...) ground the shield at one end ..probably picking up noise from the display (multiplexed spikey cruft) Jim

I was able to get rid of it with the cap on power, but I do have shielded wires on audio. more works need to be done in that area though. Joe

LM386 distortion really increases with increased gain. gain is not sensitivity. a better idea might be to bypass pin 7 to ground with the 10 uf. either way, keep experimenting. I tried an external

Hi! Would you consider adding some pads / 0 ohm links for some experimenting with AGC and other things? I'm totally cool on cutting up the board and such to do dirty tricks but having some 0 ohm links

John, you made an excellent job with the relay replacement and the two inductors mod, for the higher bands you might also consider to add the LPF Farhan filter before the 45mhz filter. I have done it
