No mention of "fuse" here:??http://www.hfsignals.com/index.php/ubitx-wire-up/ What looks like a fuse at the top left of the schematic is labeled "ON/OFF", so I take that to be the power switch on

Are the filters/equalizer/etc. compatible (as blocks) with that Teensy visual system audio library they have? All: JackAl uses the audio board and its library, so, yes, very much so. Please note:

Tom I appreciate your effort. I received a question about MAC from a number of users. But I did not have a MAC and it was difficult to test. Your test has helped me a lot. Thank you Ian KD8CEC

Ashhar Farhan First of all, congratulations on recent things. You did a hard job in a busy schedule. I have confirmed that you have maintained the existing code and have at least a few modifications.

I had some M3 Nylon Standoffs and drilled a hole through it so It just slid over the shaft.? I put a drop of super glue in from the end and rounded the corners with a dremel a little. -- Lee -

I am interested in this too. I have not received ?my ubitx yet but have been playing around with the Arduino and stm. I've ?not had much luck with stm ?f303k8 ?nucleo , mostly because like it has

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

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.
