K2KD here :) Glad to see hams getting involved -- disaster communications is one of the strong suits of amateur radio. I still have a to-be-implemented plan of getting a portable HF rig w/ solar charger for my to-be-implemented "go bag". One of the big challenges the whole hobby has faced is the struggle for relevance in the Internet era. When I got my license (early 90s), there basically wasn't an Internet for kids…

I wonder how many HN readers have amateur radio licenses? I got one last month (AF7PL). Now I'm working on getting a radio. I don't want to just go out and buy something. I want to do this old-school, and so have at least some of the major components of my shack home built (and ideally home designed). I may partially relent, though, and buy a handheld transceiver for 2m/70cm. My electronic construction skills are pre…

You might enjoy getting started with a kit like the SoftRock SDR: http://fivedash.com/index.php?main_page=product_info&cPath=1... Personally I think it makes sense to start with a pre-built radio to learn the radio technique and have something to compare with, but with an oscilloscope you can probably hack a kit into doing something useful. (I have the Softrock RX kit. Works well to receive WSPR.) 73, KD2DTW

The book takes you through the basic theory, backed up with experimentation while building the kit. You just need a a scope and function generator, and of course a soldering iron.

Is there a protocol for making your radio more phone like, that is it rings when someone calls you or beeps when someone texts you? I guess if I were to hack together an RTTY or PSK32 thing to do this my next question would be where can I find a portable cheap low power draining SDR similar to a "smart phone".

ALE would be HF base station type operation not hand held VHF 2M radio.
Low power and SDR do not naturally go together. The folks most interested in low power drain (the trail hiker/camper types) use discrete devices as opposed to SDR. Not saying its impossible of course. I have a KX1 that draws about 30 mA when listening, so "dozens of hours" on a set of batteries. It would be challenging to find a SDR system that uses similar or less. It is challlenging enough to find a smart phone that can idle for a dozen hours on a charge much less actually do anything LOL. Still, good luck with that, etc.

The only downside to the Ensemble RxTx is the sound card requirement. I'm probably going to order something right away here, but if I could have a do-over, I'd probably go for a Peaberry: http://ae9rb.com/index.php?main_page=product_info&products_i.... They were out of stock when I ordered though.
