Nice treat,? Allison. ?It takes time and patience with workmanship to implement the mods on the original pcb. Thanks and regards sarma /? vu3zmv

You either have miss wired the connector, or a bad connector.

I'm not sure you can do anything to expand the audio range. That is determined by the 12Mhz filter which has a pretty narrow bandwidth. You could move the bfo to get a 600-2400hz audio but I'm not

Allison, Jerry, I have my little mmic board built. Would it be ok to add it before Q90 by removing C80 and inserting the input and output on those pads. Doing that would allow me to stick the board on

Allison you referred to T9 being reduced to 9 turns of #28 bifilar did you mistake it with T8 which is bifilar with one winding not used? Skip Davis, NC9O

Just checked the mic at the plug.? It shows no continuity until I push the the button...then about 1.6k when I push the button. Have I wired the mic correctly?

Thanks for your help.? So I just checked with mic plugged in.? It seems to be shorting the ptt (orange wire) to ground without pushing the button.? Indicating a problem with the mic itself?

I guess i don't understand where you are going with the software... but wouldn't it be easier to convert your display work from the I2C buss? ?Then you have a whole host of pins to work with... freed

Did you check with an ohmeter with the unit off at the connector with the mic plugged in that the PTT switch is working and wired to the right pin, i.e. high impedance when not pushed, and short to

My friend gave up despite all the help I gave so here's his equipment. I have an unopened uBitx kit (I think version 3) and one of Sunil's cases (grey) plus parts also unopened.? Too many hardware

Still no joy.? I've checked all the wiring and confirmed connections to jacks with meter.? I wired up the mic and ptt button as a simple open/close circuit.? Is this correct?? Pretty frustrated.?

Allard :? You raise a good point.? By using R111 as the injection point for the constant +12V supply to the LM386, I avoid messing with the switching of the power to Q16. So Q16 is off during TX.

Well, it is a Heater Control.? Done with a Pic and Assembly done code.? Lots of nice features. I have not had a paycheck in 3 yrs now, so this design was part of a proposal. This is the nth change,

If you are like me, Kent, nothing ever works right the first time. ?So, the answer to the last question is probably "no."? I suggest building the radio into a temporary housing like a cardboard box

Just an update - I was able to load 4.3 onto the Arduino Nano by using the file Gary sent me. I used a Windows 7 machine to accomplish this. I don't think the Mac is well suited for uploading to the

But now you really should tell us what is, Mike.You have us all curious. Bill VK7MX

I need to correct that.? I am running a totally stock board.? I have changed the audio pot to fit a knob I wanted to use and have added a fan to cool the irf510's even though Ashhar, the ?BIT's

This little radio is many, many times better than what I used as a novice. I'm having a blast with it. Put it together and be amazed? Dan, W2DLC

Kent KQ4KK The mods and changes will never stop. That is part of the BITX phenomena. The transceivers are designed to be tinkered with, but basic units also work fine for those who do not want to
