I would be interested.  I have a lot of experience with all the above, and am currently retired.  I would welcome an opportunity to earn enough to fund my own projects.  Social security doesn't cover anywhere near all the projects I would like to pursue (or buy the tools all guys lust for, like a spetrum analyzer.)

Re: uBITX rotary enconder

Jim Sheldon
 

Jose,
It will not work right.  I have one and I connected it to my Raduino to actually test it (using my home made test set).  At 400 pulses per revolution of the shat, it sends pulses to the Raduino many times too fast and you have to turn the shaft very very slow to get it to keep from jumping digits forward and backward.  It has open collector outputs and the internal pull up from the Nano does not give enough current to make the encoders output transistors work properly.
If you try to connect one of these to the uBITX you will not be very happy.  Save your money.

Re: uBITX rotary enconder

Would probably have to use the 2 interrupts to read the encoder.  Do the frequency change in the interrupt, not set flag and process in main code.

I did that with the regular (less pulses) encoder on my BitX.  But it depends on how fast things go and length of code in interrupt.

Ive been on this group for awhile now and noticed posts from others in past that they were professional programmers and such. 

If this is true and you are proficient at programming for PIC, ATMEL, MSP430 series and or DSP MPUs using C or Assembly I would like to discuss a plan with you for a project I need help with that will be of benefit to everyone on this site. I can pay for your services but in the end it will be Open Software. I’ll even provide the parts, please let me know.

People might like a better option than what is already here.

Thanks,

I'm thinking along the same lines.  I built a Mic amp version using the SSM2167 and thought it might work also for the Receiver. It's essentially the Sch seen on ebay but added a level pot on the output side.

Ok, i need a pointer here.
i got bitx40 last week so i plugged in the raduino portion. bad connector on nano but i will fix that, no problem. 
i dont care for green so i plugged a blue/ white 16/2 lcd looks great.
the issue now!
using arduino ide 1.81i wanted to verify my ability to reverse my failed attempts to the sketch, by getting the original raduino 1.01 from github and compiling it and loading it so i would have a fresh restart if i blew the mod i  was trying. base line if you will. no stranger to ARD, as i started goofing with it back in 2011 at Rev 0023. 
i keeep getting compile errors on the si5351. set freq and init. failures. i have tried 4 different etherkit libraries from the earliest to the latest nothing helps me to just get past a verify.
i have read i have to modify the library.
thats bull.
how do you guys get by? whats the trrick?
i want to try shuttle tuning with a center detent 10 li8inear taper opot but wont because i will not be able to reverse it
ideas?

Now on version 0.35, another great increase in flexibility, thanks, I been trying the memory function, storing the FT8 frequencies, a small wrinkle, whilst the correct frequency is recovered from memory the stored sideband is not.  If USB iis set from the memory manager LSB is always restored, if the memory is set from the rig USB is only restored for frequencies above 10 MHz..

Re: pointer needed raduino

Michael Hagen
 

Use a new Raduino version that has SI5351 routines built in?  I was written to help those problems.

I uses a lot less memory and avoids all the problems with libraries.

You probably want all the new changes anyway?

Just a thought?

Re: top band ubitx

bill richardson
 

Doing some testing with my uBitx on 160m with a 160m LPF attached to the output. I’m seeing about 15 Watts out but the current draw is running very high at just over 3 amps. So not usable on 160m at the finals will blow I’m sure. The bias stays normal so it’s something else? I wonder what others are seeing?

Doing the same test on my Bitx40 on 160m I see about 10 Watts out and the current is about 1.5 amps and very usable.

Did you read the documentation for 1.27.7?  Allard does a great job documenting exactly what you need and how to get it.
You need to add that library into the IDE.

Re: top band ubitx

bill richardson
 

Right I could do that and use it just on 160m. So as is I’m seeing about 2 amps on 80m and it goes down as I switch to the higher bands. So going lower from 80m to 160m I jump over an amp to 3.2amps. It’s interesting and just wonder what others are seeing. I don’t see such a jump when looking at my 2 bitx40’s.

Re: top band ubitx

John Backo
 

Bill:

I think what you are seeing is the "normal" variation in the
output of the MOSFETS. Some are better than others at RF.

Gordon's suggestion to turn back the drive is probably the right answer.
Alternatively, you could turn down the gate voltage a bit, but that
would probably introduce compression distortion. Or you could increase
the size of the heat-sink and see how it goes. Probably the wisest thing
to do is both turn back the drive a bit and increase the heat-sink.

Some, but not all, IRF510's are capable of 20W or more on 80m.
you might happen to have some good ones. The key lies in the
harmonic generation and the heat-sinking.

Note that what you are seeing MAY be from UHF oscillation included in
the signal. Be very aware of that. Check your output very carefully.
