This is an older model scanner that was sold at Radio Shack and likely other outlets probably in the late 80’s into the 90’s. It has Wx, scan and manual buttons, 10 channel memory and a key pad with Lockout capablities (and keypad off/on switch.) It can run on 12V DC (tip positive). [...]

The Icom T90A is a nice looking tri-band amateur transceiver (sending on 6M/2M and 440) with wideband receive. It has weather alert scan, 555 memories (scannable). THe transmission power is either 5 Watts or .5 watts selectable (high/low). It looks like a fairly nice little unit, metal case. I don’t recall [...]

Another amateur handheld that’s caught my attention is the Yaesu VX-2R it’s a microminiature (I’ve read that it’s smaller than the picture appears.) It has wideband receive and transmits on the 2M and 440 bands. The output is 1.5 Watts on 2 Meters (144-148 Mhz) and 1 Watt on the 440 band. [...]

A while back I looked at Scanners… that got the bug in my head again for looking at amateur radio equipment. The pick of the handhelds that I have looked it is probably the Kenwood TH-F6A, it transmits in the 144, 200 and 440 amatuer bands (with 5 watts output) has a dual receiver [...]

Transistors act like switches, a small amount of voltage can control the flow of current… most transistors are silicon based and take a few tenths of a volt to activate… imagine a substance that allowed switching with just one electron of current… that’s graphene, which is a form of carbon that is only one molecule [...]

You’ve got to love stories of ingenuity like this….. In this case a New Zealand tv broadcaster is saving around $20,000 by using a $10 wok… the commercial video link equipment just cost more than they had to spend to get the station up and going, so with a home-made designed transmitter link using [...]

I know, this one may be just for my interest…. but I want to make sure to post this before I lose the links. KE3IJ has some nice home built simple radio projects on his site that look like fun little projects. In fact, I’ve got some component s on order for another [...]

I should also mention… another scanner that has had really good reviews and is available in the under $200 category. That’s the Radio Shack Pro-97. (Available for $150 on sale from time to time at Radio Shack.) I’ve seen some really good reviews. The Radio Reference wiki page for it is [...]

Now we’re into the more expensive end of the units out there and this means we’re talking Digital… Uniden BCD396T TrunkTracker IV APCO Digital Handheld Scanner with 5500 Dynamic Channels Currently it’s selling for around $550 and boasts digital reception of APCO 25 signals (Trunktracker IV technology…) APCO 25, from what I understand, [...]

This one is a little newer than the bc246t… and a bit more expensive ~$260 Uniden BR330T Nascar Scanner TrunkTracker 3 with 2500 channels It’s big claim to fame is that it has continous band coverage from .1MHz-1.3GHZ (with the exception of cellular.) The only disadvantages I can see with this one compared [...]
