What is bitx23?


 

Have you got a update to this new unit . also would you be willing to make the filters for 2m also?? I like the work you have done but you dont have the making for the filter boards and what you used for a amp... I am looking to get a 6m setup if you have them or the updated gerber and a case you use ...
?


 

hey Charudatt,
?
I have clean simple 6 meter code you might want to look at...
?
writen on the raspi pico and a sh1107 1.3 oled.? it has alot to it . contact me a n4cnr.ham@... I figure if we team up and make bot a 2m and 6 meter set of kits we can make this a great project. I have started working on a vfo board.??
?
I also have rit on a encoder working ... I have alot of functionality to explain
?

so I have 2m and 6m code emulations , I have to add in memory storage , but I figure I would share what I have done. its more basic as mine will be for sota/pota and I dont seen the need for alot.?

any new updates did you finish you amp circuit ?? btw out new code I am almost done with is si5351 based and circuitpython. it should be finished this week ,the current code works but have not had a scope to test the si5351 wav with
?


 

when you get closer pls show as I am reviewing this further for 6m and 2m? ..
?


 

what vfo code you going to use as a base? or are you writing new code...

I am working on a rpi pico src based on what farhan started but its going?to take time to grow correctly . I know the kd8cec firmware is ported to other boards but the work to rm 10-80m and all the relays and filters is going to be a issue
. also have to decide?on what screen is best I need 2.9 or higher as my eye are going bad slowly.?

I have a git hub?of what I have done thus far posted and I am working on more and trying to fix the si570 ino file?

This is independent of the clock source. You need to add that to this design externally.

I planned to use a Si5351 along with it.

can you point to the si570 chip you use and where to buy ? as everywhere I look no one sels less then 50 at time...

I share the Gerbfile of the project , BITX24

?

Should anyone make it, request to share the outcome of the same

do you plan to release gerbers so others can use/ make your board ? and what is the size of the board looks to be alot smaller then a normal bitx ...

?


 

Yes surely, I can release the Gerber. There are a few breakout board used in this project, so will need to add them in the panel and then release the Gerber.

Please give me a day or two to make the panel and then share it with you'll.

BITX24 Details

Farhan designed/presented a BITX23, 6M SSB in his QSP issue of 2023 and I designed mine in 2024 hence I called it BITX24.

?

This idea of my BITX24 was a result of studying 2 designs on the topic , viz Farhan and by Chrix found on YouTube. Both , built on the principals of BITX principal.

?

During my earlier development on sBITX, I had already made some Break Out Boards (BoB) based on the uBITX TIA block which I plan to use in this project, hence you see some blocks in my schematic. I have had blocks for a Ladder Filter, Rx/Tx TIA, and a DRM (Diode Ring Mixer). These blocks are no specific design but adapted directly from the uBITX design.

?

Signal Source (Si5351) design is external and connected to this board via SMA Connector.

?

Using of Blocks has made this design more compact , in my opinion.

?

This is just the Exciter Board and the front end BPF/LPF can be adapted from either of their designs.

?

I planned to use MAX9814 MIC amp with AGC but then simply copied Farhan's MIC amp as a standby on the PCB.

?

Choice of LADDER filter is yours and I would go with Chrix's idea.

?

Charudatt VU2UPX


 

I have drafted a board. Shall post details soon.

I would love to make a 2M rig. That band is pretty busy around here.?

also there would be a few mods needed help with like changing the mosfet to the rd15 and adding a power adjust?pot so you can go low 1w to 20w , also for ssb need a mic gain circut?for better output with some mics.

other parts to add in future would be a alc att sql if shift. but those can be added in future

well I have been working on code and make the pico duino board. I am swamped. if you hand a kicad or eage?cad file of the schematic of the board it would make doing it easier. then we could do it faster. but having to re do everything from the pdf to a cad is time consuming and not easy.
