Lower bookshelf and my wolf river coils ham antenna
 
Good eye yeah just got it in the pic. The handbook of reactive chemical hazards by bretherick. Could come in handy one day hehe
Several years ago our state library decided to throw away most of their books, i was able to get about 50 boxes of them that i rescued from the shredder and most were great emergency prep and prepper books!! My library now covers bout anything!!
 
Out here in the badlands of New Mexico, internet is SLOW and intermittent. Good think we have books! Our library has book sales about every 3 months and we always do the sales. Walk away with a big box of hardbacks and paperbacks for $5.00! That is where I have bought boy scout books, reloading manuals, US military survival manuals. The kind of books 90% of the people would not even look at.

As captjim said above and with the original poster this is why ham radio is important when internet goes down we still have email via winlink, can send images out of destroyed areas via slow scan tv, text messages via all sorts of digital formats, voice when phone lines are down, etcetc.
 
Of the digital modes I prefer Yaesu's System Fusion / C4FM. I do use it while talking to someone via simplex. This kind of allows for a somewhat hidden transmission. If you don't have a Yaesu radio with System Fusion it sounds like nothing more than static.

Fusion, DMR, P25 and D-Star are all unintelligible without a decoder. The advantage of DMR is it has two time slots and can carry two conversations at once. The disadvantage is that its probably the least expensive to get into due to the proliferation of DMR transcievers from Anytone and beofeng. I've used a rtl-sdr ($25) with sdr# and dsd+ to decode dmr and p25 phase 1. Of course we're talking well beyond the skills and interest of the unlicensed baofeng brigades but it can be done.
Now if only someone could come up with a way to do winlink over one time slot of dmr and voice on the other, one repeater to would handle digital voice and email.
 
Our group uses strictly P25 now for local comms. Best audio (unless you count All Star, which we all have for traveling as well) out of all the digital modes. We also have an HF rally frequency that is also he nightly rag chew freq. If you have a digital scanner you can listen to P25 comms. Also, building DMR code plugs is not for the neophyte, it takes a little involvement. C4FM is pretty much plug and play.

Yeah, P25 and DMR can at least turn on encryption if law and order breaks down.
When I got P25 decoding on my PC, I was turned around messing with the dog and it sounded like a cop was standing on my desk talking behind me but their repeater was 30 miles away.

I have Fusion and DSTAR, and am now trying to wrap my beady brain around DMR. Trying to make my own codeplug is what is problematic for me. But I will figure it out

I kind of went at it backwards. Started listening to dmr with dsd+ and watching the real-time packets scroll on the computer screen. My work also uses dmr so seeing those packets with what I knew of the setup made the slots, colors and everything click for me.
 
MY dstar radio has been a REAL pain to program, still havent gotten it right!!!
I have to go back and watch the video I did on the Icom ID-5100A so I can refresh my old brain on how to program it.....

The whole color thing and time slot is what is getting me. I never know which one to put in. I have tried following what a repeater woner may have listed, but still a no go.
