DIY How to add DDS to Bitx | Bitx40 | Ham Radio HF Transceiver

[@Emtron_Technologies]

Dear Friends. Please watch complete Video, You have a chance to win ARRL book & Pixie Transceiver. Friends, I'm still a SWL. I Don't hold the Call sign VU3SWL. For a Demo, I displayed VU3SWL on LCD.

Receiving a BC station change / modify BPF for the required frequency band and change vfo ( running ) in software section.....

[@eCMastermind]

You changed the band pass to opening brode casting and 10mhz if filter

[@TheJamnagari]

Informative video. Cabinet looks cool. Keep it up. Good to learn.

[@Emtron_Technologies]

Thanks for the feedback.

[@Emtron_Technologies]

Set a BFO Frequency to 12MHz, then you can listen to BC Stations.

Nice Video and useful my Friend. I am using the same BITX40 V3 Radio with vu3vrl's DDS VFO and working OK. Now, I face some problem with rotary encoder, when I rotate it anti-clockwise to lower frequency, the response is normal, whereas for increase of frequency, the response is very slow/poor. I need to replace the encoder. Kindly suggest me it's availability. Thanks. ..... vu2rdx, Sekhar.

Nice project, keep up the good work. And I encourage you to get your ham license and get on the air.

[@Emtron_Technologies]

Sure.

[@kolhatkarchinmay]

Ausome video..It actually reflects your efforts. I can visualize the future growth of your channel...and hope it is time to start comparing with EEV blog. Make more awesome stuff.. everyone will support you!!! for #Ans. I need to research long.But I will definitely try to ans it.nice thanks.

[@Emtron_Technologies]

Thanks for your support. I hope you can win this contest too.

Why are you using a level shifter? You calculate CLK0 for what is the VFO output used? As this vfo seems only for display purposes. Do you have some kind of lpf filter behind the CLK0 CLK1 before entering into the dds on the bitx, resolving interference on the blockwave by the dds signal? Ron - PA3FAT

[@Emtron_Technologies]

Thanks for the feedback. Level shifter is used because Si5351 operating logic level is 3.3V & Arduino is 5V. CLK0 output is 4.8Mhz to 5Mhz for 40m band. and IF Frequency is 12MHz. Absolutely VFO (7MHz for 40m) is for display. Don't have any LPF filter behind, But their is a 12Mhz Ladder crystal filter at in IF stage. Please check the details about Bitx40 circuit diagram provided in manual.

[@Emtron_Technologies]

Yes, You are right.

[@aneespi4684]

Is it possible to toggle between USB and LSB.?DID you tried this in 20m

[@Emtron_Technologies]

No, I have not tried it.

[@ea7kbsjesus419]

Very good proyect! wonderfull.

[@Emtron_Technologies]

Thanks, Please keep in touch with us.

[@RadioMaker360]

I almost finished mine

[@ASHOKKUMAR-xd5gu]

ya i got it thanks ,, keep inventing for ham radio

[@Emtron_Technologies]

Welcome. Please keep in touch with us.

[@ASHOKKUMAR-xd5gu]

@@Emtron_Technologies> yes,,.sir thanks for u r response

[@amer1337]

Is this the same, or different then the one that comes with the bitx40 ? Or mabye i not know what a VFO is mabye, its the screen that gives you what frequency your on right?

[@Emtron_Technologies]

Its a different one. You are right, display frequency is the one you are working on. VFO = Display Frequency - BFO.

[@ASHOKKUMAR-xd5gu]

excellent modified coding how can i get ......i use si5351a as a vfo for my dad bitx transceiver 2015 to 2017 i got coding from ak2b

[@Emtron_Technologies]

You can download from GitHub. Link is given in video description.

[@new2radioz]

Just a note: the Si5351A by Silicon Lab is a clock generator not a DDS like the Analog Devices' family of AD9850/51 etc. Nice job otherwise! Now, go get your ticket!

[@Emtron_Technologies]

Thanks for the info.

[@GMELECTRONICS365]

Very interesting video.

[@Emtron_Technologies]

Thanks for the feedback

[@martyjames6204]

very interesting, thanks

[@Emtron_Technologies]

Thanks for feedback. Keep in touch with us.

[@SANJAYSINGH_73]

It's not compiling. Kindly update the Library....

[@Emtron_Technologies]

Will update it soon.

[@pa3fat]

Hi, Looked at your sketch. Looks really great and structured coding. Super. Using struct's is great. Did not know Arduino c supported this. Some new learned. Tnx ! Working on same together with W5KUB (check out fb or here on yt). Will follow your developments as of now. Ordered 2.6 colordisplay with touchscreen on ebay. Will be working on getting this to work when it arrived (digole.com tft). And final: get your license. And hopefully will meet on the air one day. 73 Ron - PA3FAT

[@Emtron_Technologies]

Thanks, Definitely, we will meet on AIR ASAP.

[@pa3fat]

There is 3.3v next to the 5v on the UNO.

[@Emtron_Technologies]

We are using the customized board. Not the UNO.

[@pa3fat]

ok, planning to switch to nano when all tested on the UNO. Also checking out the Nextion enhanced LCD currently.

[@Emtron_Technologies]

Excellent.

Thanks

[@w3les]

Outstanding and Great deal...but i have a problem understanding your speech. i am sorry but do not be upset i just have a problem you speak to fast ....de w3les

[@Emtron_Technologies]

Thanks for watching. sorry for my bad accent. Will try to improve. de VU3TXF.

[@rogeronslow1498]

I cannot understand what you are saying!

[@Emtron_Technologies]

I'm just explaining How to add DDS to Bitx40 Transceiver.
