Good piece of information. How can I measure 50mV in the audio frequencies? I have a Velleman 0-100mV 1khz audio generator kit, but a cheap multimeter does not show a thing. I hope I don't need an

You should probably upgrade.....

Thanks will check and reply.

Subhash, L2 is not properly soldered, check continuity on the board and resolder. If that does not help check L1. Raj

Others like myself have wished for a TFT file for the 3.5" Nextion screen that fills the whole space. While there are a few out there, they don't mirror the "original" format that we know and love

I have ordered the AGC board and looks to arrive on Monday. I will let you know if it will work. Comparing my v5 board to a V3 board it is the same size and layout so it should work. That’s my hope.

I am trying to fix the recieve on my bitx40 but it wont recieve until i touch the L2 coil near the relay. I dont know whats the problem. Help would be greatly appreciated.? Regards? VU3EDU SUBHASH

Very cool! =Vic=

Morning Dave. Thanks for the information on the mouse details,im at a loose end today so will delve into my junk box as i now ive an old wired mouse there.Soory to hear about your wife,our 30 year old

IMHO, THE NAT54S ARE INTERALLY matched. As a strip, same batch the second bat54s also has similar characteristics. Can we get such balance with 4 discrete diodes, it is a long exercise to match etc

I am using the mouse as a (ceramic) microphone for my Drake (the capsule fits perfectly in the place of the ball). Indeed I could use the two now unused buttons for a cw key as you have done hihi :)

I'm building my uBitX v5 and have a couple of questions about power supply voltage. ? First, what are the minimum and maximum supply voltages that the uBitX is happy with? ?I may be powering the

Dave Nice to see this idea revived as I know I saw it decades ago for portable operation. Not everyone is doing 20 or 30 wpm and that is okay. A bunch of us also do mechanical keying in straight key

Hi Tim I have a v5, am happy to test. Send me the file to print and I'll take some photos. Cheers Ben

I like this. Reminds me of an old Star Trek movie where a crew member from the future was trying to use a mouse. Tom, wb6b

It is more sensitive bc of the different transistors it's using .

Yes, you are right about the mixer on CLK #2, and the CLK #2 frequency needing to be set to the TX frequency (as in the CW mode) for an unbalance there to generate a carrier. Thanks for the

(*chuckle*) This is the coolest thing I've seen all day! I'll admit I use a capacitive Touch Keyer with two horizontal paddles that I alternately touch with my index and ring finger to send.? That's

Adding discrete diodes and a pot for the modulator to better suppress the carrier has been discussed here. I haven't heard of anybody who has done this and decided it was worth the trouble. Being an
