Don't get me wrong, I applaud your willingness to reach in and play with your uBitx. That's what these rigs are all about. Just taking the opportunity to let others in the forum know that twiddling

Vince, I'd like to know more about the uses of that tape. Do you have any additional tips or links to explanations of the tape? Thanks Roy WA0YMH

Yes, Kapton Tape is recommended when using hot air for [de]soldering. Vince.

A few more details here please: Is the receiver working properly now? When you measured "Current 170. Smoke coming", is that 170mA and what current were you measuring and were you pressing PTT? It

I answered some of the questions, method. I made a tight setup with everything connected with SMA connectors on a tiny PCB. Shorten leads on the transformer.? Now much better! SWR about 1.3:1 ??

ok wonderful people...here is what I have done. 1. I hooked up the raduino to pc and checked volts, all good. 2. Disconnected? pa power turned rv1,2,3 all fully clockwise (towards metal dot on

I had a few days playing with my crystal filter PCBs. I spent most of Sunday learning about my Siglent SA.? Spectrum Sunday! I had in stored out in the shed, a sin.? I don't have room for all this

A second thought and question about the zener voltages. Is there a way to estimate what the output power in watts will be at various voltage levels?? I need to get my Low setting below 3 watts so I

If you could draw this up that would be great.? I am no EE just a layman enjoying the hobby.? From what I can tell Zeners are in the mAmp range and I thought I was told in an earlier post that I

The voltage from the wiper pin (middle) of the tuning pot is read by an analog pin on the Nano to determine tuning.? Measure the voltage from that pin to ground using a DVM, it should vary smoothly

What software are you using? The original? What version number displays?

Tayda has the best prices and stock.? Look under connectors, wafers, 2.54MM (0.1"). Find the 2 parts you want and buy pins.? So 3 items per size (Pins).? Watch out, there a 90 Degree

simple series pass regulator on PA supply line. i would probably go with 4 zeners on a 4 pole rotary. ie: 5.6, 9.1, 12.0 and 15 volts so then the output is "adjustable," with fixed known intervals.

Hi, my bitx40 has decided to start tuning erraticly! It will tune itself in 10khz steps to the very top of the band or the bottom. And if it’s not doing that then it is jumping and tuning all over

That should be Molex KK series connectors

search eBay for Molex ok series connectors. You want the ones with 2.54mm pin spacing

Disgusting Scrooges and Grinches Most authorities these days would make you pay to breathe.

*This might be of interest to those trying alternate FET's or just trying to improve response of the driver stages. This is a sweep of the driver stages in my uBITX. I disconnected the input to the
