Hi DaveW, I have done three different AGC mods to different uBiTx versions. 1 - The Kit Projects AGC 2 - The AmateurRadioKits.in AGC included with the v5 Nextion display case kit 3 - The VK3YE as

Thanks Ashhar, found. 73 - Pierre - FK8IH

I was RELIEVED to find such a simple cause of the spurious problems I had encountered. *I suspect strongly that some false move of mine shorted out those diodes in the process of adding the 470 ohm

Thanks, Dave! I'm up to my ears with keeping the house and two AP courses going.? ?Wish I had more time to learn more about these things. Gordon KX4Z

An easy way to find function etc is to just run grep : grep -n "set_power_levels()" *.c

Can someone compare the Kit Projects AGC board with other AGC mods, such as the TIA-AGC (suggested by N6ALT, several posts earlier in this thread), or the VK3YE LED/LDR AVC/Audio Limiter (or the

The sbitx_gtk.c only deals with user interface et al. The actual radio code is sbitx.c. You will find this there. - f

Ashhar Farhan ( /g/BITX20/topic/92592412 ) 07/25/22 #93982 ( /g/BITX20/message/93982 ) set_tx_power_levels() in sbitx adjusts the gain etc for each band. It sets

I agree, the biggest challenge in working with Pi Zero is the small memory footprint, but once you fit into the memory footprint, having extra cores to run threads on is very helpful.? I haven't had

Since it's not worth opening up a new thread, I want to note that the way we said to build fftw3 in install.txt caused me a small problem. I found the issue while building gnuradio, when I got

The challenge of the running sbitx on zero is not the cpus, but the memory to run chromium browser. The upshot is that a large functionality that was written in javascript(easily and quickly) had to

The newest Pi Zero, the 'Zero 2 W' is 64-bit, the rest are 32-bit. Ref: Pi Software ( https://www.raspberrypi.com/software/operating-systems/ ) The official Pi distributor in the US (

Here is a bunch of guesswork:? Doing a bit of googling suggests I2S signals should be able to travel across a few tens of centimeters of cabling.? I think there are some single-board computers that

What would it take to make it look like a microphone/speaker soundcard to an attached Windows computer? Glad you are enjoying it! Learning is fun. Gordon KX4Z

In reading https://www.vu2ese.com/index.php/2022/07/20/the-sbitx-the-sdr-for-the-homebrewer/ and install.txt and similar sources, the idea that the WM8731 codec appears as a soundcard on linux made me

I had five board produced and have accumulated all the parts.? Assembling and testing one is high on my priority list.? Don't know when that will happen.

Hi Dave, Thank you for pointing out Ashar's comment that the software changes would be backward compatible: I'm excited to see these changes and upgrade the HW/SW once the information and code are

They made these open sourced so you can download the gerber files and have them made. I ordered 5 pcb boards from Jlcpcb but I didn't know that they would populate the boards too and I'm not sure how

Could this work for you? https://mostlydiyrf.com/tia-agc/ Joel N6ALT
