I have just joined this group.? I have a few extremely strange, if not difficult questions I would like some reference info on.

I have an Arduino programming guide and will attempt to use it. I would, however like code or hardware and code to add an AGC function to the micro bit rig.

I would also like to add a spectrum analyzer to the display so I can keep track of signals and contacts.

I would, finally, appreciate information on how to add a USB input that Hamradio Deluxe can recognize so I can use that software.? My X1M has a com port connector which terminates in a USB interface.

Thanks, Arv. I will do that.? I don't know how to log on to the previous work page as of right now.

If you log into the group page and do a search for "AGC" you should find much of the

prior work that has been done.? Since the audio path does not go through the Arduino

it would be difficult to do software that implements AGC or filtering inside the

micro-controller, but might be possible to have software functions that monitor signal

level in hardware and control attenuators or amplifiers.?

For your spectrum display question, you might want to search for Farhan's "sweeperuino"

comments.? He designed and built a spectrum sweeper based on frequency synthesis
and an Arduino.? This could lead you into something similar as an on-board function in
your BITX transceiver.?

Since the uBITX uses an Arduino NANO controller it already has the necessary USB

interface.? What is not there at this point is a command interface protocol for external

control of the transceiver.? Recently several have been discussing what can be done in

this area, and how to implement it.?

If just getting started with Arduino programming it might be worthwhile to purchase a

cheap Arduino NANO (Ebay suppliers sell them for around US$2 to $3 each) and use

that to familiarize yourself with the hardware platform and various software applications

to use that system.? You might be the one to come up with the next fantastic BITX

function.? ;-)

Welcome to the group.
