I have built 3 so far and have had great luck with no problems at all. My first 2 builds was with the V3 boards and both had great audio on RX and TX. I just got the V5 board and it has worked equally

Expectations? Mine were to be able to purchase a kit, build it and have a working QRP HF rig (much like I did when I bought a HeathKit back in the ‘60s). I purchased the V4 board and the case, spent

I want to work qrp out in the field... I want to have a worry free experience? without worrying about a threat of citation from the FCC. Since this equipment is sold commercially,? I fear reprisals

what are your goal and expectations? ? -- www.bitxmap.com ( http://www.bitxmap.com )

I have been looking for a different gui for my 3.5 as the CEC version is nice it does not fill the screen.. please keep me posted when the bugs are out? Thanks K3BO

Hi everyone! The question is should I wait to buy a ubitx due to the problems with version 5 with regard to suppression?? I have the Nextion display and case on order and have around $150 invested in

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
