Yeah...I showed one of my junior soldiers (and fellow HAM) my posting and it sparked a long discussion that roamed into the 20m range. I was educated on a few points and I think your 20m argument is valid...however I'm reminded that there's not very many good mobile units are 20m capable.Hi Ryan
27.555 is the CB DX calling frequency (a misnomer) for "freebanders". Being in the 11m spectrum, it's very fluky and inefficient. And, there are far fewer operators/stations available due to its being an illegal activity throughout most of the world. Decent propogation on this band doesn't occur until the SFI is in the mid hundreds, even when using SSB and large amounts of output power. Essentially, it's worse than even 10m, which many hams love to make DX contacts due to it's difficulty.
The 20 meter band is universally accepted as the most reliable band for use in times of emergency due to its ability to work in nearly all propogation conditions. At the lowest point in any solar cycle, it's not difficult to bend a signal halfway around the planet on 20m with only the 100w output of a standard amateur HF radio.
In a total collapse scenario (as if), my plan would be to scan through the local FM repeaters in order to find which have survived or are functional under emergency power. Second, to find out how things are coordinating on an international scale, like most other hams, I'll be turning to 20m. Knowing that there are ham stations set up around the globe that are already using alternative power, or are set up with back-up power, I'll have no concern about finding other stations to contact and possibly gain info or help.
IC-706, IC-7000, DX-70TH, FT-100, all good and mobile-for-vehicles HF rigs. The station limitation with all these radios mobile is the antenna and even as stationary at home they're not exactly terrible radios.??? The Yaesu 857 (and even the 897) and the Kenwood TS-480 spring to mind; I'm sure there are quite a few more.
Not disputing what you said, though I think a better qualifier may be in order here...Hardest part about CBs is getting them installed properly and then the antenna tuned optimally. Most never or don't know how to tune their antenna and there in lies the rub...no range or very little range. Range is the most common issue with CBs even when tuned. They are basically line of site with lowest power settings (<5W), most don't even get a mile in range. Granted, CBs are generally significantly less expensive than a ham nor do they require a license (at least most of the people I know don't have a license for a CB or GMRs/FRS - even though in the USA one is required for GMRS). GMRS/FRS have come a long way from CBs and their range is significantly better (up to 20 miles I have heard) with less things (antennas, tuning, cables, etc.) to fuss about.
There's no need to look any further. The website is more powerful than the phone app at narrowing and filtering, so I find it more useful setting up a radio. Also worth noting the phone app needs cell service to access the database, so you shouldn't wait until you're already off grid to check.There's an app for that! I use RepeaterBook, which shows apps by location. It's free.
You can cache the list of repeaters and it will still monitor your location and give you the basics on the phone. Pretty cool stuff.There's no need to look any further.

Didn't know it could cache the database, but I may be running an old version of the app. That would be handy indeed. My device is SIM-less and doesn't belong to any Google account so I have to remember to update things manually.You can cache the list of repeaters and it will still monitor your location and give you the basics on the phone.
