Here is my mic housing, I printed it up to work with the supplied parts.? The element drops in to the hole, the button snaps into the side, the three posts have holes in them to wrap the wires for stress relief.? I've also got a back printed up, but I haven't put it on the live version yet.? This was the testbed print, I ended up moving the PTT up higher and to the other side because it didn't fall under any fingers in this spot.

uBitX with CAT control and Split operation?
Hello
I am planning to buy/build a uBitX for dxped use.
But not sure about CAT control and VFO split ??!

That is to be determined based on the
performance I get. Right now, I will adjust VR1 to get 5 watts on
40 meters and go from there.

How you propose to control the drive to be of 5 watts
on all bands for your 70 W amplifier
As the uBITX is giving much more power out put on lower
bands? than on the higher bands

Probably no mike gain control because the audio input is designed for
approximately 45 millivolts level and the included electret microphone
puts out approximately 45 millivolts.?
Secondary reason is that it avoids possibility of cranking the gain up
too high, overdriving the balanced modulator and causing unwanted
emission products.

Finally have this one where it will get it's top cover put on and the radio goes into the "go box".? With the addition of one of our RadI2Cino cards, an I2C 4 line by 20 character display, a Teensy 3.6 adapted to plug in place of the NANO, this one is on the air in what will be it's final configuration except for software updates when we release them.? (External USB connector in place so the cover need not be removed for remote control or Teensy 3.6 programming. One nice thing about using the Teensy is the built-in Real Time Clock!? UTC time displayed on the screen and with a backup coin cell battery, the clock stays active even when no +12V is applied to the radio.Also, I added Don, ND6T's neat little AGC mod and boy does that work nicely.? Here are a few pix of the radio as it now stands. Jim Sheldon, W0EB

Re: Coast to coast on my ubitx yesterday

power source is a 10 amp linear 13.8v Tripp-Lite. Logged stations in
Maryland, Florida, NY,Montana, Utah, California and states in

Missouri. The longest contact was 1500 miles in Northern California.
I am using the stock electret microphone.
Have also done some CQ ing on 7277. I did find two Hams with bitx
radios One that had his radio out of the box but had not put it
together. The other was N3GO Gary in Raleigh NC, He had a bitx40 that
was modified. I talked to him on both my ubitx and my bitx40. He said
that there was not much difference in signal. I definitely hear
better on the ubitx.??

Re: UbitX I2C GPIO Breakouts?
Unless the display is changed by one of the other tasks there is no reason to update the display. It's not like you are preventing the other tasks from running while you automatically update the display on a regular basis. The speed of sending display updates via I2C really isn't that much slower than doing it direct. In essence, the I2C backpack on the display is just another co-processor that offloads controlling the display from the main processor. I can't argue with the fact that multiple processors provide more computing power. However, as you point out, all those processors have to communicate with at least the main processor which, in turn, slows down the main control processor while it is communicating. You might cast an ADC unit that communicates with the main processor over I2C on an as-requested basis as a co-processor. The main processor isn't required to actually process the voltage on an analog pin, the ADC does that. The main processor just gets the result of the read of the analog value, it doesn't have to actually read the analog value first before it processes it. tim ab0wr On Thu, 19 Apr 2018 21:36:27 -0700 "NNicholas via Groups.Io" <NNicholas@...> wrote: No, it's not a big difference in speed, that is until you consider

haven't started on this all just yet, but from previous projects.? In
the past ,? ive found cop-rocessing with multiple prcoessors on an
I2C bus to not only offer greatly improved speed up of operations,
over all; it makes dividing up the project a bit easier too. The only
challenge, that I ever found in multiple processors , is at start up,
where you want to make sure that all the processors are talking
before entering into each of their program loops . It's not that hard
to code and you can find plenty of examples on how to do this.

Mine with a stock electret:

Unless the antenna is picking up a static charge and the antenna tuner is
acting like an impedance to ground draining that charge off. Don't laugh,
it happens.

A matched antenna shouldn't "tame" the noise.

I just had a thought about new users of the uBitx and the Bitx40.
I have both of these fine rigs but with my good antenna - a ZS6BKW

- the receivers are swamped by noise and big signals on 40 metres.
When I tested just now a 59+ 10 signal on my IC-7300 was unreadable on
the Bitexes with the big antenna (which has a low SWR at 40
metres) because of noise. With an antenna of just 6 feet of wire in
the shack the signal was readable (but weak) on the Bitexes!
I usually use a tuner beween the antenna and the Bitexes - that works
fine to tame the noise. Also I have fitted an RF control to the
Bitx40 that helps quieten big signals.
But if you have lots of noise in the receiver and no tuner - try a
smaller antenna on receive (it will be no good for transmitting). If
that improves things maybe you need a tuner or an RF control.
