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

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.

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.

Here is the .35 release: https://github.com/phdlee/ubitx/releases Marco - KG5PRT

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

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

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

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

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

Hi, all! A link from where to download version 0.35, please! I found only 0.33! Regards, Emil

*This software is for the original uBITX Raduino with a standard (NOT the I2C) display. * *The zip file contains a complete, illustrated manual in PDF format that contains detailed instructions on

Hi DR fellows Just asking if anyone is thinking to change the rotary encoder of the uBITX to an optical encoder due the not good quality of the uBITX encoder.? can it is possible? I found this on

Good morning, Bert The project does not require a shield. The 2.8 display plugs directly into atmega2560. Others sizes of display will plug in as well Files info located

The characteristic curves for different operating voltages are right in the spec sheets for them. Its a simple matter to pick the proper curve Vds curve and adjust the bias to the correct operating

Hi there Alex. Thanks for the info. I am thinking of doing the same as AGC is needed with some QRO signals in the bands. Based on the attached schematic that I use for reference I have a couple of

Can you point me to the software to download into the ATMega board?? Thanks! Is the 3.2" TFT display with an expansion board shield mounted to the Mega? Bert

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.
