Re: Newbie instructions for loading software in Raduino #firmware
Easiest to just clip all the pins to remove the old nano, then extract the pins one by one using a soldering iron and needle nose pliers.

Re: A friendly suggestion for Farhan.
You know, I¡¯d love to see the uBITx as a kit.? In fact, I¡¯d take it as just a bag of parts and a circuit board¡­ skip the assembly and testing.? I¡¯d do that myself.? What that would do is

Re: Core for Output Transformer
No the power transformer T11. The ?BN61-002 shows lower loss than the BN43 equivalent.??It¡¯s 1:2.? I¡¯m gonna try to cap couple it so it doesn¡¯t carry the DC as soon as my iron heats up.?

Re: Core for Output Transformer
Think of it this way¡­ if you spent $9 US on a pair of RD16HHF1 FETS¡­ then what¡¯s another $6.50 US to bring them to full life?? Save the 202 for the choke. ? *?* *Dr. William J. Schmidt -

I use RD16HHF1s¡­ I think you will find that the BN61-002 wound 1:2 runs cool. ? *?* *Dr. William J. Schmidt - K9HZ *? *From:* [email protected] [mailto:[email protected]] *On Behalf Of* Skip Davis

Re: Raduino CAD Files
Joe, Thanks as I also have one of those encoders and planned to use it.? My plan was to make the changes you have done. Saves me a bit of testing. The STM will make doing color display easier and

Re: Newbie instructions for loading software in Raduino #firmware
The Arduino board is soldered to the other board. I used a hot air gun on the pins connected to the other board. Then one of the solder sucking guns out clean out the holes.If you get an Arduino board

Re: Using IRF530 outputs and 2N3553 drivers in ubitx
Don't know enough about the minipa 70 to comment.? Is there a circuit out there to look at? The Wa2EBY I have has run at 65W (40M) brick on key mode for nearly 20M before I called it good.? Only

Re: Raduino CAD Files
Hey Joe, good to see you taking on the uBitx! I don't think Farhan has not released mechanical data, but here's gerbers for a Raduino replacement that Nik may have gotten right through careful

Re: Mic doesn't work in bitx40 #bitx40
Most dynamic mics are like speakers with 50-500 ohm voice coils, Most are not very compact with an OD of 10MM and up to as large as 30mm.? That is at least true for ones I have. Electret mics ar

Re: Newbie instructions for loading software in Raduino #firmware
Failure to connect may be due to wrong USB driver, wrong board selected (under tools), wrong port selected (under tools) or maybe even a bad cable. I will not suggest more than at for now as for me it
