I’ve been playing a lot with the EFJ 5100 series portable radios. The radios are excellent units by my standards (I will admit to not yet having used an XTS 5000). I have a couple of original EF Johnson battery chargers for the 5100 series. They’re moderately strange looking items, allowing you to place the radio in as normal for charging on the rear battery contacts, but also a slightly unconventional method of strapping the battery to the charger.
One of my hobbies is Radios. It covers everything from building your own radios with a soldering iron to collecting old police radios and reprogramming them for your own use. It’s pretty fun. Keeps the nerds busy. However, as you dig deeper and deeper into the radio hobby, you will undoubtedly unearth some of the older radios. When the cops upgrade, they dump massive quantities of (for the most part, excellent) radios onto auction sites like eBay. Hams and other radio gurus sweep them up in great quantities. Until you find out one particularly sad fact: you need DOS to program them. And often, the slower the better. More on radios elsewhere, today we cover the DOSmonster.
Yesterday at the MIT flea I happened upon this gem, a little bad boy from Wilcom called the “MODEL T303B SIGNALING SENDER.” What is it do you ask? I have no idea. What does it do? It beeps. How much did I pay for it? $7.
