I haven't looked at Ian's code yet. But suspect it is plenty readable. And if it's readable, there's a bunch of people here that could support it. And I doubt Farhan would ship with it unless he was

OK, I _think_ I improve the image a bit. I put the CAD file and the image on the site as well. Accessible from the assembly page. W7PEA

During PTT I get 1.6V on the emitter, 2.2V on the base and 11V on the collector.? I'm getting supply voltage(13VDC) on one side of R66 and 12.5VDC on the side with C64.

On TX there should be large voltage on both side of R66 if not then maybe a relay fault or faulty Q6. Check all the voltages around Q6. Raj

If CEC firmware is selected to be the delivered "base" then you must think about the following two implications: 1. Is Ian willing to support the "base" in the future w.r.t. uBITX production hardware

That is partially correct. In my keyer code I use the spare pin too. So converting my code to work with one pin is not as simple as changing one #define. rOn

Yes... the microphone case is ground...? blue wire is going to ground and continuity checks good to ground everywhere as best I can tell.? Even the metal part of the microphone shows dead short to

I love the red, can you send code faster with the red case? ;-) W7PEA

Tim When I write software I don't have reuse as part of my mindset. I try to make something work that is broken or develop something new that does not exist. Once it is tested it is given to the

Check the mic polarity. One of the leads behind the capsule is connected to the body and that is ground Check if there is 12v is on the mic transistor stage when you press ptt. Raj

Hey Max... care to add some comments to describe this circuit for newer folks. Do so here...? /g/BITX20/wiki/uBITX-Reverse-Polarity-Protection

Hi Kees, 2 of each as well please. 73 Nick VK4PLN

Hi, I would like to order one AGC and one Click kit. John kc9h.

+1 about the poll, HFsignals need to know what their customers are really doing. 73, John (VK2ETA)

Ron, If I want to add a "Tune" menu item which puts the rig into CW transmit upon key closure and also measures a voltage indicating the amount of reverse power just how do I set that menu item up so

Hello Tim, The keyer input is also defined so your program only need make reference to the defined label (ANALOG_KEYER here), not the hardware pin per say: From the code: #define ANALOG_KEYER? ?

Here is a link to the info: http://barrie-wax-group.blogspot.ca/2017/04/minimum-bitx40v3-hacks.html Hope this helps, Marco - KG5PRT

Tim... I think that's where we are today...with the base level, bare bones code shipped from the factory. An increasing number of people are gravitating to the CEC firmware and that gives you an idea

John, You will need to do the front end diode protection mod before you transmit near your bitx40 or you can blow the front end... I will look for the info and will post it here. Marco - KG5PRT

Hello Tim, At 45.45 baud and 170 Hz shift it would not be an issue to do it all by software to meet the frequency and timing accuracy requirements. Writing the frequency for the next RTTY bit to be
