I currently have a 2m handheld and a single band mobile in the truck. Certainly those will do the job... and since I'm not needing the dual "listen" function frequently....

Does this indicate that this one would NOT listen to two 2m frequencies?

So the FTM-500, while advertised/listed as 2m and 70cm, can be programmed to listen to two 2m frequencies?

This thread is the starting point for that search. In addition I'd like a remote faceplate style unit.

So what do I look for to know which is which? What in the specs will be the tell?

Does the radio "stay" on the frequency that broadcast last... for some period of time? If you want to reply how do you select the frequency to broadcast on?

To try to clarify (and it is probably obvious that I am a relative newbie): When I'm out wheeling at an event and there are two groups, each on their own 2m frequency, I want to be able to hear what is going on on both. By "hear" I mean I don't want to miss an important transmission. I do...

I understand that you are both saying there are work-arounds to achieve this function. I'm wondering if there are specific radios that allow this as a built-in feature.

I see most "dual" are "144/440".. Will some/any/most/all "dual" radios allow monitoring of two 2m (144) frequencies vs 144/440?

OBVIOUSLY I'm new to the LiFeP04 world.... Compare and contrast these 2 (non-self heating) options please. I DO see that one says "4 cells" and the other "16 cells", and they are packaged differently, but otherwise...?

And would the low temp itself damage the battery or would damage only occur is you tried to charge the "cold" battery?

Self heating would be important if the battery would be subjected to temps below....?

Great suggestions... Just not falling into the cheap/too good a deal to pass up categories. (Yes, I know: usually you get what you pay for)

There are a million odd brand batteries out there these days and I know that some are trash and some are quite good, and... it's (another) Prime Day. I'm wondering if there are any stand out deals on less expensive (cheaper) but still great quality 100ah LiFeP04 batteries (Prime day or...

I fully understand that there are 1000 questions to answer and I also know that this is new to me.... my first "camper" build. I really do not know where I will end up with this. I'd like to get started with a solid, basic system. I'm trying to make the choices now that will leave options open...

Yes, I think 30 or 50 amps of charging potential would do the trick to supply any 12v loads (thru the battery) and charge the 12v battery at the same time. With that Victron "3" I could charge the engine batteries at the same time I think.

Thank you for this great info! I KNOW I dig too deep oftentimes. Thanks for pulling be back from the edge!

If I want to be using the 12v battery loads while charging off of shore power would I want a 120>12v charger that can supply more amps than I am going to be pulling from the battery (on average)? (a net gain for the battery)

So neither the 24>12v charger or the 120>12v charger will have a problem when one is energized and the other is not.... OR if BOTH are energized?

Context: a Land Cruiser Troopy environment (24v stock electrical system) 12v DC loads need power (fed from a 12v fuse box) Sources: A. 120v >12v power supply B. 24v alternator/main battery bank >12v converter C. 12v "house" battery I would like to prioritize the source selection for the 12v...
