I received my BITX40 kit and wired it up on my workbench. The receiver worked well and I made three QSOs before disassembling it to install in a homemade case. While reassembling the IRF150 tab shorte

!!!!!! It's alive !!!! It was a burned trace. I traced the voltage and saw 13.7 at L8 and 7-9 at T7. I soldered a jumper on the back of the board from L8 to T7 pin 6 and now I have 13.7 volts at the D

AAARRRRRGGGHHH! Lost it again. After reassembling into case I no longer get power out on transmit. Receive works. Voltages on Q15 look correct on receive and transmit. 0.17 A draw on receive jumps to

I also shorted my IRF150m to ground and and blew a fuse. After that I had no power out. Following a tip on this board I traced the voltage from PA PWR1 through L8 I found that there was no voltage at

I have an Arduino Uno and have compiled and uploaded sketches to it. When it is plugged into my computer a serial port appears. I have compiled one of the updated sketches but can't upload it to the R

Thanks for the response but I think that the problem is that the computer doesn't find a driver. There is nothing to uninstall. USB2.0-serial shows up under "other devices" and device status says no d

Jack Last response was before I saw yours. When I run dpinst-amd64.exe the Wizard starts and I let it run. After rebooting nothing has changed, USB2.0-serial shows up under "other devices" and device

Three USB ports. One has a mouse in it. It's a laptop so the keyboard is built in. As mentioned it the original post, when I plug my Arduino Uno in I get a serial port and can compile and upload to it

Installing the CH340 driver did it. While playing around I tried yet another computer. I installed the latest IDE (1.8.2) on two Win 7 laptops. One worked with the nano out of the box and the other ne

data point: increasing the drive level to 4 ma caused a much louder birdie in my BITX40, so the drive level has some effect. Bob

I had a tough time calibrating my BITX40V3 when speaking into a mike connected to a commercial transceiver transmitting into a dummy load and listening on the BITX. I finally hit on a method that work

Nice your uncle Bob

I hot glued mine and cit seems to work well.

Fernando - Nice that you recognized the Mosley. They are pretty rare. I was lucky enough to have one like that in the mid 60s as my first real ham receiver. Simon - There is a standard mica insulator

Ham Radio Workbench shows 5 and 6 are an intro to oscilloscopes. They interview Alan Wolke, W2AEW who is referenced above and has posted many electronics videos. /http://hamradio360.com/index.php/work

I'll be there and at Four days in May. KD8CGH

Jack I would like 2 boards. Bob KD8CGH

I just placed my first order with Tayda on the 22nd and got it from Colorado today (27th).
