Re: Cricket 40

Frank:

I powered my KX3 this morning first with an Astron linear supply.  I turned off the AGC, set the radio to 7040 kHz, and cranked up the audio gain to max.  There was no antenna on the radio, so all I heard was background noise.  Personally, the hum from the Astron sitting a foot away was about as loud as the noise coming from the radio.  Next, I removed the Astron supply and attached my 18 volt string trimmer battery running a buck converter that I bought online.  The voltage was set to 13.2 volts.  I can't remember where I bought the converter or what brand it is.  If you'd like, I can look at the converter PCB and see if there are any identifiable markings on it.  I think I paid $3 or $4 for it when I bought it a couple of years ago.  Anyway, I honestly couldn't tell any difference in noise level when using the two different supplies.  I'm sure if you put a scope on it, you could see a difference.  According to that informative video we were pointed to a few days ago, the noise gets worse as the load increases.  The KX3 current drain on receive isn't very much but I suspect it's a whole lot more than that of a Cricket 40.  Otherwise you couldn't power it long with a 9 volt battery.  Furthermore, I suspect a Cricket 40 on transmit doesn't draw much more current than the KX3 on receive does.  So without having a Cricket 40 (or an antenna), I would think you'd be OK.  You aren't risking much money in either case, about the price of a high quality 9 volt battery.

I hope this data point helps.  If you need further information, let me know.

72,

John, AA0VE

Hi John,
Just curious if there is any noise radiation from the buck as compared to a linear voltage regulator.
