bingo !!!!!!! Really the problem was it is in vfo CLK # 2 I inserted the rf generator at approximately 52Mhz and now we have the normal operation of ubitx. Probably some defect in SI5351. Lucky I have

Greg: If you are aware of what happened, just get new deices and install them. You probably will need to redo the alignment as IRF510s are notoriously variable. You CAN let the adjustments alone, but

First post - be gentle :) I have been playing around with the ubitx for about a week now. Pretty cool radio and I like the idea of modifying the software. Installed Ian's version of the software v1.04

I don't do a lot of SMD projects and so I don't use a mask just manually apply the solder paste from a syringe that the paste came in. My advice is that you can't have too small a nozzle. In the

I finally treated myself to a Hakko 888D to replace my 30-year-old Weller with regulation in the tip. The difference is night and day. The Hakko heats practically instantly and lets you know when it

Substituting the Raduino to eliminate the problem suggests this was another case of oscillators beating together in mixers to give rise to annoying audio tones. Mike ZL1AXG

Doesn't look like the photo made it the first time.

This site is definitely worth using when you are looking to get PCBs made. The last time I used it it suggested ALLPCB which had an offer on at the time so I got 5 boards for $5 with free courier

If you don't use a speaker with your uBITx and use only a headphone. best idea is to add a 1K resistor to the negative lead of C77 (470uF capacitor) to charge the capacitor slowly when first power

I would take the pricing with a grain of salt, the results showed a price double what I recently paid to have an order made from one of the China fabs.

Hello, Due to family issues I have not posted in a while but I have ordered parts for my experiments with Bitx. Two items of note that others may want to play with are: SA575DTBG Low Voltage Compandor

I give my 2 cents and you gave me something else. Thanks Vince. Sent from Yahoo Mail. Get the app

There is a wide variety of antenna possibilities listed in the Files section here. Both the uBitx and the Bitx40 are easy to assemble. The one area that might be a hang up is the case. In order to

Hey Nick… did you make any progress? I’ve been dying to dig into this but work keeps getting in the way of playing with my radios. That’s gotta stop! Something is up. You can actually put

Hi Mike I had the same problem. I checked Q90 and found E & B are shorted. I replaced 2N3904 with a regular type transistor Instead of the SMD type. I get 30 W but I tuned it down to 15 W.

Thanks Ashhar, I didn’t realise it was that simple! Keep up the good work, I’m an experienced amateur having started as a listener in 1967 aged 11 with boatanchor sets (still have a few) but

After about 8 weeks of working on it slowly, a few minutes at a time, I've finally finished boxing up my uBitX and it's now up and running FB. The box and mic holder are 3d-printed from a design I
