I think a lot of hams over do it in this area but I like to call mine a "field box". See my profile pic. I have a iPortable2 with a IC-7300. I also have a power supply and sealed battery wired up so I can quickly deploy, run of AC, and when that fails everything still works.
3) QRP / SOTA
I just sold my KX3 and plan on getting a KX2 for travel.
4) Software Defined Radio
I have a SDR-Play which I sometimes break out to listen to interesting things (ADS-B, etc).
JT9/JT65 is interesting.
I have kids and they seem to like radios.
Would be great to do a contact with the ISS.
I built & maintain a local GMRS repeater for our community.
I'm interested in linking more of our local GMRS repeaters together possibly through AllStar or Wires-X.
D-Star Images & Hotspots
G4KLX & MMDVM - If you know linux and want to build a D-Star hotspot from scratch.
W6KD D-Star Commander - If you have a Raspberry Pi and a DVMega/DVAP this is a great turn-key image. Created by Bob W6KD.
D-Spot 2.0 - Want a turnkey box that does everything? This is a very reliable piece of hardware that has MMDVM. Supports DMR, D-Star, Fusion, and more. Great solution for mobile. Has custom scripts that make the unit very reliable when using an iPhone, Android, etc.
DV4Mini - Nice little USB stick that does all the digital modes. I use this connected to a Pipo X8 Windows 10 PC. Allows me to have touchscreen access to all the digital nodes.
Hardened Power DHAP - Hotspot package. Has buck concerter, battery, etc. Pairs nicely with D-Star Commander.
Debug of Call Sign - Very helpful to monitor how the D-Star network sees your call sign & hotspots
