What were you trying to use as a power supply? I currently use some pretty darn cheap power supplies until I pony up for a real one with battery backup. I have batteries as a backup, but it involves pulling the powerpole from the PS and swapping it to the battery box. If you get a good 30A power supply, you should have zero problems with any single "base" radio. If you get a power supply that needs adjusted, you tune it for 13.8V with zero load.

What confuses you? Icom does not come with an internal power supply, you must provide your own 12v (13.8v) power source that can provide enough amps for the radio. 7300 requires over 21A, 7610 requires over 23A and the 9700 requires over 18A. I'll revise my statement, the 7851 has an internal power supply.

I have a table of interoperability from NOFIG of the DCS codes, and which normal means an invert (i.e. 023N = 047I). It is in excel format. It also has CTCSS tone to P25 NAC for what it's worth. One heck of an OST (operator selectable tone) list.

Anyone interested, I found an updated version with the revision date 2023 that works on current android versions: https://bitbucket.org/VK2ETA/andflmsg/downloads/

That's what I was talking about earlier. On version 1.5, I get this message: I'm on Android 15 with the January security patches. If anyone can repackage it for android 15, let me know.

I guess what do you determine significant? You should be able to make that up in antenna gain really easily, but 902 is more line of site than 440/GMRS, so you aren't going to be chasing skip.

They are packaged in the same installer, we will let it slide.....

It's an excellent tool. There is a version for android phones, but it's too old. They published the source code, I just don't know what I'm doing when it comes to recompiling it to the current android, otherwise I would have done it already. It's nice to be able to decode announcements on the go.

FlDigi is way more than just text messages. It's used by our ARES group for a weekly digital net using MT63-2000L with a 1500 passband, and at the end all the announcements are sent back via the same mode.

I have crossband repeat available in the cars. At home I use an analog hotspot for home coverage when I don't want to jump on the base. It's simplex and connects to other repeaters with allstar. I have tossed the idea of building a small repeater that I could connect to one of the base stations, but haven't gone down that road yet.

The published operating temperatures are -20°C ~ +60°C, which is -4F to 140F. You were definitely outside the operating temps. Most of the commercial stuff is rated for -22F to 140F or better. I've never had an issue with my Kenwood stuff, and that comes on when the car starts.

Did you have logging on? Is there any error codes pulled when you connect to CPS? It sounds like there was some kind of internal protection that tripped, but it's hard to tell if something actually fried, or if it needs something reset.

Spreadsheets are one's friend when building large codeplugs. I also save every revision as a new file, with SN, version # and date as the file name.

Same, considering I just bought another HT, maybe 3.......

Any time I do listen at Walmart, you can't hear them once you leave the parking lot.

Grab a scanner and spend some time listening. It's usually either not used at all, or overrun with wireless driveway alarms. It never seems to be in between.

That is a great PSA. Thinking through it, I can understand why the programming is that way, but I don't think I would prefer that vs. manually changing DCS/CTCSS.

Why would you buy the roll up version if you are going to stick it in PVC like the standard version? His instructions are very specific on the type of PVC pipe to buy that it is designed to work with, anything different changes it's effectiveness and match. I'd suggest buy the other one for next to nothing and put it in PVC.

I use the Larsen's.

You do have to keep in mind lighting requirements over 200' AGL I believe, that is FAA safety.

It depends entirely on what radio you are using. On the Midland radios, I think you can only program 1 repeater for each pair, meaning you have to switch the tones when you want to switch repeaters. Others are similar to the Midlands. The Part 95 certified LMR radios (Motorola, Kenwood, etc.) can just add another entry for another repeater.

Same

I'd listen to both.

Any CERT team should not be using the cheapest radios they can find. In that case, stick with cell phones or zello. For a club, why wine, just use FRS radios for $15/each and not worry about licensing. For GMRS, you are required to use a GMRS certified radio, not a MARS ham radio. I've bought plenty of Kenwoods for what a majority of those certified CCRs cost. There are too many places that people want to be cheap where they absolutely shouldn't. CERT is working with someone's life. Motorcycle clubs, you are riding a $45,000+ bike, and won't spend a few hundred bucks on a decent radio? I just don't get it. It's not like you won't spend money, you just won't spend it on the appropriate radio communications because there are $11.99 radios on amazon and "that's such a deal, it just has to work well enough". The options are there, you just won't hear it: 1) Stick with FRS, and have no licensing, 2) Have every member responsible for their own GMRS license or 3) get appropriate LMR licenses and radios, which in the long run doesn't actually cost more when you drag it out over a 20+ year lifecycle.
