Looks good. I made a few adjustments and fixed the mem screen. I want to run it on my rig before I send it back up. Are you aware of any other errors?

Thanks, Curt. You've triggered some valid input here. Here in Enzedd we have have (at least) two celebratory event that correspond : SKN (Straight Key Night ) and QLF ( Cue Left Foot). Enjoy. Never

Looking forward to your results as well! Our hope is that it is still drop I'm compatible with the V5 board and from the pictures we have seen it should be. However like any honest person we

Thanks Jim! My vacuum tube SB102 was built the same way. I’m guessing this accounts better for other unsymmetrical things in the circuit outside the diode’s

Iz I would start with a pair of fixed-gain op-amps to bring the voltage up to where your test equipment can measure it reliably. Arv K7HKL _._

Brutus, I have rechecked. And I stand corrected: the simple optoisolated interface (4N25 and usb-serial converter) works perfectly too. Evidently, when I checked this before, an audio jack adapter was

I can just say it worked for me.

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
