Re: bitx40 newbie build, if touched IRF510 switches and locks to transmit, takes 3A
For our one IRF510, a good size for our heatsink is half of the 24 sq inches that Allison uses for two devices, and with 1 inch fins. Lots of good heat sink material in old PC motherboards and power

Re: bitx40 newbie build, if touched IRF510 switches and locks to transmit, takes 3A
I mentioned heat a couple times in my last post. ?That is not your primary problem, the IRF510 is not hot when it first goes into oscillation. Allison's post is worth going over thoroughly if you

51.2 ohms is great. ?Anything between 25 and 100 ohms is ok when running the final from 12v. ?Not an issue if you are only attempting to receive, I doubt any VHF oscillation would get through the

Thanks, Jack - this is a help. The Raduino seems like a great device, and I think plenty of Ham projects could be built around it.? r.rking41, I have all of the Arduino stuff I need. Raduino is what

Re: bitx40 newbie build, if touched IRF510 switches and locks to transmit, takes 3A
Thank you both for the feedback. Yes, when I said into transmission, that was probably inaccurate. There is a similar sound on the speaker as when I switch to transmit, but when I look at the output,

Re: Firmware on github does not agree with what was in Bitx40 as shipped
Jerry I am sorry you are having the same low power problem. It was making me and my test equipment look really bad. There are three things I did to make it work. #1 Set the bias with no audio to 100mA
