Agreed. Great work. Mine will have that plexiglass panel. Makes the display pop. All kinds of gamer pc lighting possibilities. And the visual “works” very Mr. Machine-like. Are the

My present layout (on the screen now) extends the Raduino width about an inch or so to the right (inside). The Pill board is set in toward the left about 1.5", leaving room on the right for a very

Allison and all, with the KD8CEC firmware you can opt for a I2C display connection; the display can be remote quite some distance with just 2 wires (plus power and ground). Rod KM6SN

The problem is everyone wants a simple swap this part a poof its wonderful. Applying a simple fix to only one stage is not going to achieve that. The IRF510 has been used to ge high power it can with

2n2222a. Surface mount or metal can version?

RIght now I'm using 2n2222A with acceptable results. The KSP10 might be ok too, I like the price.? ? MPSH10s are on the way already but will not have time to use them?till next week. Right now

For the life of me I do not understand why the diode is before the fuse. The fuse should always be first as it needs to operate for all faults even reverse polarity. Allison

I know it's not the best but the shunt diode did protect my MTR 5. My problem was I did NOT have a fuse in the line so the smd diode let the smoke out (opened up as it vaporized). I now fuse all B+

peeps, jack, ian, allard, arv i have created a next version of the base software after thinking hard about it. you can download it from https://github.com/afarhan/ubitx4. I invite you all to test it.

It's certainly possible that it works in some cases. But without a fuse, that shunt diode scheme is not an insurance policy I'm willing to buy. Worse than nothing, it gives is a false sense of

Hi, is the 330pf across the PA transformer mod all what is needed to get reasonable output (5w) on 28mhz or should I also make the Farhan mods ( Replace C81 from 0.1uf to 470pf Replace R83 from 10

Just use some hear shrink to increase the shaft dia..

Tell that to varidur.? Reverse protection diodes are cheap insurance.

Thanks for your reply.. I've already swap the leads of the electret mic. But the same thing is happened. What voltage suppose the capacitor showed exactly? is there any limitation on how big the

I got a bit frustrated finding a knob to fit the 6mm knobs on the uBitx.? Fortunately I found these adapter sleeves to bring the shaft OD up to 1/4 inch so I can use standard American 1/4 shaft

This reference suggests silicon diodes generally fail with a short when subjected to over-voltage. And generally fail with an open when subjected to too much current. ?

Generally silicon diodes will fail with a short circuit, protecting the hardware.

I just want to say that I'm very happy to see you take this on! Jerry

Tom: If we are talking about the VFO/TFT board, look for the place where we read the encoder. If this is the BITX code, look for the symbolic constant ENCODERTUNING around line 1720. At line 1729, you

Cuz sheet metal work is not as much fun as burning solder. Shielding various sections of the radio from each other is not a bad idea. And the Raduino/display is a good place to start. Allowing the
