Interesting! And, yes, AGC was exactly the term I was looking for. I feel a bit sheepish for having forgotten it. :oops:

One thing I'm still a little confused by is what the V16 does. You are very clear that it does not do AGC, but then you mention amplifying weak signals. Would that have a ...

Do any of the MGL radios offer dynamic compression of voices? I'm fiddling way too much with my Becker AR4201's volume knob-- close-by is too loud and far-away is too quiet--, and would love a solution.

That's an excellent description. I guess this is one of those rare moments in science where analog components wind up burning through *less* energy than their digital equivalents.

That's quite some clever SDR you've got going. Silly question, but how hard would it be to get to the 157MHz ...

Thanks for the bench test. Understood completely about the SMPS current vs. power ratio.

Out of curiosity, what's driving the idle power load? Unless I misunderstand the Becker AR4201 specs, it's idle current consumption at 13.75 V is 0.07mA, or just under 1W.

From the Becker manual :

Power ...

The v16 manual says this about the supply current:

RX: 0.3A at 13.8V, TX: 2.5A at 13.8V, TX into 50 ohm dummy load.

However, it's not clear to me if the published RX load is while driving a speaker, driving headphones, or simply in idle state waiting for an incoming transmission.

I fly gliders ...
