Power supply

[email protected] #23066 I've been lurking for a while now, ?my Bitx40 should be here any day. It occurred to me today while driving, I don't recall seeing any discussion about power supply. Wall wart? Battery? Other?? regards, Richard? W2KAP toggle quoted message Show quoted text On Mar 7, 2017 9:03 PM, "davetelling ." <davetelling@...> wrote: I just ordered mine.

Too bad there's a halfway this weekend. Maybe I'll get some build time Sunday afternoon. Wish me luck!

I have used various power supplies with mine. 12v bench supply, 14.1v LIfe battery, 19.5v laptop power supply and a benchtop supply at 28V. In all cases I have ?a 12v regulator inside the ?case to power the board and raduino and the seperate (high voltage) goes to the final. Effectively I can power my BitX40 form any supply between 12v and 28v and everything works. at 28v I get a bit over 20w output. at 12v I get about 5w output. -- Mike VK3XL
College Professor Simon Thompson #23071 开云体育 A good power supply always makes a big difference to the way a radio operates; I think the Bitx40 is a great opportunity to build a power supply, with a big capacitor and a line filter and a transformer and everything! I am building one right now out of spare parts from the junk drawer. toggle quoted message Show quoted text On Mar 7, 2017, at 6:40 PM, vk3xl via Groups.Io <vk3xl@...> wrote: You will prpobably need something that can deliver about 1.5A at 12v well regulated.

Lawrence Macionski #23084 I bought a wall wart, cheep when if first got my BITX40.. from ALLELECTRONICS.COM because-- always a because --it was cheep, had the power connector on it and-----AND--- I also needed to order other items for my build ---and ALLECLECTONICS.COM had them.. Matching knobs both 1/8 and 1/4 diameter for the pots, a speaker, and other odds and ends.. such a 12MHz crystals 4 for a $1....which I will experiment with the BITX40. They have a flat rate shipping so.. The point I am making is that I've been using that wall wart since...you can't but the parts to build one for what I got this.. Besides if I get ambitious, venturing further, a battery based system would be in order..
