Hummmm.... well couldn't find the file MorseCode.h so I had the computer look for it. MorseCode.h is not on my computer. NO place! Mike, WB8VGE

Okay a quick peek inside the B40SoftwareRe10106 folder shows nothing but that file. Nothing else. Mike

Jack and the group, I'll dig through and let everyone know. I find that the Ardinuo IDE really likes to hide files. mike, wb8vge What *exactly* is in the directory

What exactly is in the directory named: A:\Users\User\Downloads\B40SoftwareRel0106 Jack, W8TEE To: [email protected] Sent: Friday, August 18, 2017 1:25 PM Subject: [BITX20] A little ardunio

I am on the road so I can't verify this but I think you actually must have the compiler connected to some version of the arduino for the code to compile. I think I ran into the same issue; but, there

My BITX-40 is built in a wooden and clear acrylic case so all of my build, can be seen in or out.? Keeping in line with this type of construction, I decided to make a hand mic out of wood also, which

I to all, I'm Valerio, iu5hkj. For a mistake, I've connected one of the orange wire that came from the Arduino Nano to the power supply, so Arduino dont't never works. Can you help me? I need the

Do you have MorseCode.h in the same folder with the BDOSoftwareRe10106.ino file? If not try that!

guys... According to DHL, my bitx40 won't be here for a week or so. So, I'm playing the ardunio IDE. downloaded the file BDOSoftwareRe10106. Have the right files in the libraries. Although I

Hi Jonathan, thanks for your follow-up. I am sorry you are still having roblems with the pop. I have just discovered I marked the wrong pin on my circuit diagram, I reported pin8 as the power input

I just tested my r141 on all 3 bitx radios I have all are 10ohm but I will change them for 1/2watt resisters I up graded the pa heatsink today as seen on my photo I not planing on running more than

Thanks for reply all. I have the equivalent drive level resistor. ?The procedure call for pre setting the IRF 510s to 50 ma each, and then adjusting the drive level pot until the increase in voltage

Could you post a drawing please?

None BiTX, but hope it is of interest to others if it hasn’t been mentioned elsewhere. QRP Labs are in the process of kitting up a new Mono Band 5W CW Kit for the HAM Bands. A great feature for

p.s. no extra bits really needed for my unit, transistors just what was to hand (scrapped from a PC PSU). If Ted has put in extra caps it would likely be to keep it muting a few milliseconds after PTT

Hi Ted and all ... back from having my tea ... that V3 circuit is my choice, *BUT* connect to pin 3 (across the input instead of pin 7. Pops all gone, PTT press *and* release! 73 ...

This is the version I used. I see when I have another look it is version3 anyway it seems to work for me. circuit as below. I added at the junction of the 1k resistor and the emiter of the 2N3906 a

Hi Ted,, Pl post the Version 5 circuit diagram..Your HB assembly nice construction...tnx n 73 de Raj ,VU2SMM

Hi all I have made up and installed version5, now all I hear is the relay clicks. Photo of board attached. Ted ZL1BQA
