 Hi, all!

A link from where to download version 0.35, please! I found only 0.33!

Jose,
I have one of those and it outputs 400 pulses/revolution.  This may present problems for the software to read properly as the standard uBITX encoder puts out about 24 pulses/revolution.  The software to read the encoder would have to be changed to make that optical one work right.

Thanks for the reply Joe. 

What version of the firmware you are using with CAT support, or is it your own? I see there is a github repository that uses a modified version of Allard's 1.24 firmware: https://github.com/ggibby1/BitX40-1.24-FT857d, that claims to have added support, but I haven't given it a try yet.

use an opamp with a gain of 10 (20 dB) and an audio AGC system using a SSM2166.
I am working on something similar for the microphone side with a SSM2167, and am doing a lot of thinking about how to do that on the RX side.  Someone recently used a programmable TI audio amp chip for compression and limiting.  I was thinking of using the SSM2167 in a similar way, and leaving the stock µB audio amp in place.

That could work fine as a high impedance probe for use with an oscilloscope or spectrum analyzer.
To use it with a DVM you will need to add a diode RF probe or similar at the output,
as what it sends out is an RF signal with the voltage 10x what it sees at the input (20dB).

The AD8307 based probes can be used directly for sniffing out low level RF if all you have is a DVM.

I haven't used any of those ebay probes, have no idea how well they work.

I purchased this one. My radio tech manual shows test points up to 8v so I think this probe should cover it. The other one said 3v input max. 
 

Re: Diy oscilloscope #parts

Jerry Gaffke
 

A voltage divider formed by a couple series resistors to ground placed on the signal of interest
can be used to reduce the incoming voltage.  With that, the AD8307 could easily deal with higher RF levels.

I personally haven’t tried the cat functions yet but I have been following the guy who made that addition in this group. I sold my bitx40 but I am waiting for a Ubitx to try it out with.

uBITX wiki

I've been adding to the uBitx Wiki as a way to find posts on mods and software. I urge software and hardware mods authors to keep the wiki current and for others to populate the trouble shooting wiki. If we can keep the wiki current not only can we find useful topics, but we can reduce people asking the same questions over and over.

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.

Jim, W0EB

Re: uBITX rotary enconder

Michael Hagen
 

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.

Hi,  James

I'm ready to help You.

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,

It's the Wiki link on the bottom of the left hand side list of links on every groups.io page.
Click uBitx, then mods or software

Re: ubitx AGC?

Glenn
 

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.

pointer needed raduino

LKNDAVE
 

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?
