Better than a radar detector in my area of the country

Good movie..."I heard it on that radio there" as Wild Bill Kelso shoots it in the gas station, and his plane starts down the road.

Before it was batteries with serial number "500000AE928E" used for XPR3x/7x and APX900/4000 series Motorola radios. Batteries could have different branding and markings, but were always serial number "500000AE928E". Now, it appears that they may have changed the serial number to "693651350574". Picture shows "Elxjar" as brand name and then the same serial number for all of the batteries. (Some advertisers may be lazy and cut and paste pictures too, so be sure to check your actual batteries for the same serial number). Check your "Motorola" batteries, and make sure you do not have many with the same serial number.

Use one that looks very similar, but might need that "Farsometer 2000" label for mine

Monitoring analog UHF near my work right now. Always busy on UHF, and a lot of DTR series Motorola radios in use on default TalkGroups as well (they were sold to many on the local river to get away from the UHF users that proliferate the area). Lots of vessel crews, barge workers, construction and flaggers on DTR, and those that did not get that memo, still using cheap UHF blister pack radios.

Have been using SDR's for a long while now, as well as software defined military radios. Wat made me break into the amateur side was finding out that Icom was supplying the first few "black box" receivers for the Predator (RQ-1, surveillance only, no Hellfire missiles back then) fleet. The civilian versions of the PCR-1000 had some issues, like being able to be opened up like those purchased for military/export use. Now, like others have mentioned, I monitor my own networks with SDR receivers, and the HackRF is better than the cheaper USB versions, but it is so easy to just carry along a small USB/antenna and listen to what is nearby. For portability, I used a re-purposed Hinge Health Amazon Fire tablet and SDR# with USB dongle. For the money, great combination and makes the tablet useful again. My newest "scanner" would be a Uniden BCT-15X (possibly a handheld Uniden floating around somewhere), as the SDR USB sticks are on every older computer now, doing something at some point.

My employer has a "Spectrum Management" organization, while I fall under the "hardware" side of the equation. I have had to specify this 2017 aspect to them so many times it has led me to send them to some of your videos for layman's term version of FCC legalese. We use everything from Motorola TalkAbout series GMRS, to APX8000/8500 radios.....and where the specific model meets the needs and legality of the area they will be used (nationwide). So many people do not understand that things changed in 2017.

Ok, that is pretty funny. Although, in my case I would probably have some three letter agency come at me even for that. I work in a unique clique. Still, may have to buy some of those.

"Take a look at the Motorola XPR "e" series and the Vertex EVX radios if you want to see what a SDR chip coupled with good electronics and a little filtering can look like. Heck, even the older CDM mobiles had great analog receivers with some nice audio." Why I use CDM 1550LS+ (surplus from previous employer) and a XPR7550e for GMRS use now. Great radios that do what I need them to do. And will most likely last for years doing so. Better equipment, and paying attention to detail on coax and antenna means better signal quality, less power loss and more reliable use.

For local Search and Rescue, used FRS/GMRs often in the past (decade or so ago) as many state and national parks tried to popularize FRS Channel 1 for emergency use, but it seems to only be used by little kids asking "hello" now. Even some search and rescue helicopters were equipped with Garmin Rino series GPS/radios.....and a local park claimed that these had been used to find some lost hikers at some point, but possibly just a local anecdote. Unless Garmin's have improved (they have several generations of newer GPS/radios now), they seemed like a great idea but never saw them actually used much for emergency situations. Just good to have if you find yourself in a situation where location is known via GPS, and a radio signal might be heard.

Yes, while the ones in the unit work, I did find several online vendors that have "tube kits" for the SX-24/25, not too bad of a price, ~$65 to replace all the tubes. Might buy a kit just to have when one finally goes. They do get hot, noticed to top hinged cover had some black scorch marks from the tubes that get the hottest.

Wife knows I can find something birthday wise in many larger thrift stores...so she encouraged it and we went for my last birthday to an area with a lot of them. Bought an old Hallicrafters SX-24 with matching speaker. Doesn't look like much but still works (most of my "gifts" were radios from several stores). Not going to hide my purchases, last was re-casing kits for some well used Motorola XPR-6550 handhelds (right after getting the SX-24 and some other older radios).

Have been fighting some sites buying these batteries, to include the Motorola APX/XPR knockoff through Grainger......and wondering why the chargers (Motorola IMPRES) and Cadex condition charging profiles do not work with them. either the batteries get very hot and charging stops, or they all have the same chip/serial number and fail the IMPRES charge/condition charge cycles. Have forced many to do what they should have in the first place, buy from reputable vendors (one's who at least refund you if they sold fakes, or ones that do not meet sales specs). mAh capacities seem to vary a lot, and you can feel it in weight in many cases.

However, my tastes also go the way of Kugellager above, I have a lot of Hallicrafters receivers as well. Most recent acquisition this past week. SX-24 with speaker. Needs to be cleaned up, but is fully functional. The "No!" on the speaker was next to a note card stating that you had to buy the radio before powering it on (I discretely plugged it in, with the volume to minimum and turned it on as the speaker was not connected - wanted to see if all the tubes worked at least).
