UHF/VHF uBITx equivalent


Fred Buecker
 

Is anyone aware of a VHF and/or UHF band "version" of uBITx? I am aware of the DSP-10, but that project is rather dated and does not seem as straightforward a project to undertake as uBITx is.

I've seen things like the Ham Shield for an arduino as well as some "hacks" using various SRD receivers. I'm trying to find something a bit more useful than a hack, yet still able to be upgraded and customized like I see here in the BITX community.

I know it's off-topic a bit, but I still appreciate any input you guys might have.

Thank you!

The RDA818/DRA818 is a VHF/UHF transceiver IC used by baofengs and the like. There are a number of projects (including hamshield I think) which use it.

Hi Fred.
This is also on my project list. I have both the V and U version of the DRA818. I am planning on a simply desktop unit powered by arduino and a nokia 5110 lcd.
a cheap baofen mic/speaker. Just for experimentation and local repeater access as these modules are only 1W... maybe even do APRS...

In the end though, If all you want is a cheap V/U radio, just buy a $30 UV5R...

But, this is not much of a homebrew. The challenge would be to build something from scratch.

I have a UV5R. 2 actually, LOL. It's not as fun as building something, even if it's from a kit, though.

Building helps me to gain a deeper understanding of the technology and I can go over it with my kids and teach them along the way.

Looking forward to what you come up with!

Thank you sir! I had just stumbled across this last night as well. While not a full home-brew as you call out, it certainly can be a cool project to work on with my kids!
