Using with AGC

[dwhacks]

Im wondering how to use this with an AGC in the uBitx. I have the AGC board from shop.kit-projects.com based on ND6T's design. The AGC has an S-Meter hook up point, but when I use this I'm not getting anything on the spectrum or the s-meter. I tried connecting it to vol-high and the results didn't seems believable, and this might be due to the AGC.

Do you have any ideas how I can use these together?

you should be hooking pin 5 on the nano to S-Meter tap on the AGC board. But you wont get all the features of his board with that,
The Kit-projects agc board just outputs an analog voltage proportional to the input.
This is meant to sample the Audio input and perform some features with that.
Compatibility with this might not be the greatest since we are performing gain control at the antenna and the V-Hi tap might no longer be accurate for an S-Meter reading

Thanks for the reply. That makes sense! I am just trying to get the most out of my ubitx and an AGC really seems to help!

I will have to look at the code, but maybe I can seperate the "s-meter" and audio input sampling parts to two different pins, and then be able to get an accurate S-meter value from the AGC and get the audio for the other features...... just thinking out loud here..

That should work if you can properly separate them. Which should not be to hard as the DSP mod does not use the Original A7 which can be used to sample the AGC :)
