?Check the WATT setting. How much is the currenr draw on rx and how much on the tx?

Hello Allan and Ashhar, Yeah, I look forward to seeing others building the Daylight Again radio.??
I am still on the fence, but waiting to see others' experiences building the radio. I want to home brew a HF SSB voice transceiver.? And when Ashhar posted his email about the radio, I thought this would be a good rig to build.? Or maybe home brew a BITX.??
I was also tempted to buy the BITX kit just to get the parts - and build it using Manhattan Construction.? I built a Crystal Tester using Manhattan Construction recently - and I really like this way of building stuff.? No flipping the board back and forth...? ?
I also like the suggestion of building the various stages of the Daylight Again Radio on separate boards this way you can individually test each board.? I really liked how Chuck Adams (used to be K7QO) built his radios where he only built and tested one stage at a time.

Ashhar,
I have? succesfully obtained all of the mosfets and transistors. I am now working at gathering up all of the supporting parts for those.
instead of trying to get the whole radio? built on one main board, I have divided up the schematic into assembly sections on individual boards which I have a large number of already. My hope is to make troubleshooting easier and modifications simpler to do.
would it be possible to change out the trifillar transformers in the driver and PA stages for something easier to contruct ?
Thanks

Re: sBitx antenna-first warning
You will also need a way to switch this in and out and a massive heatsink to dissipate 50 watts of power. A better solution would be to have a power sniffer that will reduce the power when it exceeds the upper limit and increase it back as the swr improves. This will need software in the sbitx. - f
To build the resistive bridge three resistors of this kind might be better than 3x(10x470Ohm in parallel) :?
Considering the small size of these Kyocera resistors the addition of a resistive bridge as described by Ashhar inside the sBitx enclosure would be a nice measure to definitively protect the finals.

thanks for the suggestion. Ordered a pair. There was also some talk about using a toroid, ?will try that too.?

Re: Does anyone have the KD8CEC 5 inch nextion files?
Hi Jon
I do not have a 5" Nextion, so the following are suggestions.
- You do need a separate voltage regulator for a 5" Nextion based on the power budgets for the Raduino components.? I suggest you follow the LM7805 datasheet and add the input (.2uf) and output (.1 uf) capacitors.
- In other applications I have found that the following LC filter does work to knock down switching (PWM) types of noise on the power line.
Again, suggestions to try as I do not have a 5" Nextion display.? The largest that I have is 3.5".

I don't recall hearing that on the first 5" I put together (it was a v4 board).? Putting together another 5" this weekend and will make it a point to listen for the noise.

Re: #sbitx audio control on tap
#sBitx
Ashhar sounds good, but on program start, you are creating a default file if one does not exist.? So git rm the file and it should be fine.

Ashhar - also seems that sbitx_ft8.c is missing.? Can not do a build/

Re: Postman came with a box from hfsignals
Trying not to be impatient, but just wondering if I should have received any correspondence from HFSignals after my order?? Aside from the PayPal receipt, which I did receive.
Thanks and 73,

Yes I heard it and there was a yellow band!

Can hear it transmit? Can you see the modulation ? The modulation will be a steady band of yellow for the ft8. Finally, switch off sbitx app and open the chrome and play some YouTube. Can you hear the audio? - f

Thank you Ashhar. Followed your instructions. No change in behavior. Rebooted. No change.
Unlike the pictures in the manual, I don't seem to have a waterfall display.
Also in FT8 when I try to respond to a CQ, my system never goes into xmit.
