build a SDR transceiver ADTRX1-V1 YU1LM

[0mikz]

Congrats on your video. I am also considering building the YU1LM ADTRX1-V1 and I wonder if you are using the QRP2000 kit as USB sinthesiser. Did you try this SDR on TX ?

Did you also build B1 and B2 boards?

Many thanks and success, 73's

I'm considering building one of these radios, do you have any afterthoughts or advice?

I have an oscilloscope just like that, except yours is a 524 and mine is a 526. And it has a NASA sticker on it for calibration. Good video, I enjoyed it but almost fell asleep from the music.

That program that you used at the end is so cool! How do you get something like that set up?

Cool video. I miss so much doing my own PCBs, nowadays at job or university everything I just write firmware :(

[ElectronicsIsFun]

Very cool video and SDR. Is the design open source?

Love the sdr radio.I just built the zeda sdr receiver and it works great.Got to build one of these sdr's now.have his web site book mark and making sure I have the parts.Great video

hi, can tell me from where you buy PCB?

i take some from Ebay, made china true is cheap but, poor quality.. good luck in all your projects, 73 !

[RegimentAlphaOne]

Very impressive work. I wonder how good is SDR, what are your experiences with it. How it works as transmitter?

[KutWrite]

Impressive work!

I would kill to be able to etch my own boards. I have a lot of projects I need to build. Anyone got some links?

[BlackCow99]

@Pepsifx357

There are tons of youtube videos explaining the process. I've had success using the toner transfer method if you can get access to a laser jet printer. That and you need Ferric Chloride to etch the boards. Everything else you need is normal household stuff (like an iron, a sharpie for touch ups, some tupperware, etc.)

[Pepsifx357]

@BlackCow99 I don't think I'll be in possession of a laser jet anytime soon. But thanks for the info.

[BlackCow99]

@Pepsifx357

Yeah, they are freaking expensive. I had access to one at my school. A library will have one too. You just need to be able to load in photo-gloss paper.

[Pepsifx357]

@BlackCow99 So basicaly you just need the toner to imprint the design onto the photo-gloss paper to then use it to do the job?

[BlackCow99]

@Pepsifx357

Yup, you just iron it on to your copper clad board (make sure to print it out as a mirror image!). Laser jet toner basically sprays plastic onto the page which transfers over nicely.

[Pepsifx357]

@BlackCow99 Hmm, seems you've given me some ideas...Thanks!

[compusci]

Congratulations, you did very good not only with the construction of the radio but also by delivering such a high quality video to us. Well done and keep up the good work.

good dx and 73's

Nice work! This is inspiration for me to try etching.

Great video... this makes you realise what good value pre-made screen printed PCB's are! 73 - VK2GOM
