  1. They are standard black, with no window, but just Wednesday I purchased a 10 pack of AR-15 PMags from Palmetto State Armory (who is an affiliate advertiser for SurvivalBlog) to round out my magazine pile for $89.90, free shipping. Coupon code is PMAG. $9.00 is the cheapest I have ever seen these. A good time to take advantage.

  2. Tram 1411 Broad Band Discone/Scanner Base Antenna $48


    The discone antenna is the Swiss Army knife of antennas. Listening will be more important than talking, but it can do both well enough. Most of the antennas I make are broad banded, because after awhile the antenna farm gets so thick coupling, and all sorts of hassles make running the farm problematic. I will take the compromise to increase bandwidth to reduce cost, cables, confusion and interference with other antennas. After making one good discone from scratch, at $48.00, it is smarter to buy this one.

    The home brew is flatter than a pancake across the spectrum. It can be done, but why bother if it is this cheap. Take the savings and buy a cheap back up SWR meter to check it for your favorite frequency. My discone also picks up shortwave very well, even Australia, better than the long wire, or the dipole that is usually recommended.

    Anyone remotely involved with radio, whether listening or transmitting can use this antenna. I would check the SWR on CB frequencies on this one, but I am confident that it will test < 1.5:1 from 144 to 450Mhz. If you need gain, this is not the one, yet a good radiator is not always best, when lower power is your friend. Purchasing this discone antenna would an efficient use of limited resources and space.

  3. SIGINT in a box (Signals Intelligence in a box)

    The Uniden SR30c Scanner with the Close Call Feature, Hear’m Coming:

    $99.00 is reasonable, buy here: https://www.scannermaster.com/Uniden_Bearcat_SR30C_Police_Scanner_p/10-502016.htm

    Fall is a busy time of the year. An article may ensue this winter if we do not have a ton of fun shoveling snow. Although exercise is always needed, yet it is not good if all at once. If not exhaust from shoveling, this scanner would also make a good Christmas gift during at a time of the year it would be a good to have something to play with. However, it is a serious multipurpose tool for the prepper who can read instructions, who has a penchant for play, and desire to improve retreat security. This is very important part of your retreat defenses………listening, and it is easy to implement, and maintain with a scanner such as those with Close Call type of feature, or variations the marketed name, that is essentially a frequency counter…but we can skip all that stuff and make stoopid simple, as possible and get the job done.

    As security will be job, improve situational awareness and develop intelligence with this relatively inexpensive tool that can stand guard 24/7. It sips power, less than 2500mah, and without the Close Call, the older analogue that you may already have in a box some where, those scanners need less power, as low as 75mah (milli ampere hours). Any scanner can work, but with any of the modern generation Uniden scanners with the Close Call function, frequencies that are unknown, and not programmed-in, can be picked up if the signal strength is high enough. Using an external antenna, such as the discone for $48, will greatly enhance this ability.

    Discone antennas often come a cable with a BNC connector that will attach to most scanners.

    It is certainly worth the extra power consumed, the batteries used, to cover an important part of the security plan. Cost of purchase is low, it is cheap to feed in terms of batteries, and it is multi-purpose. It can listen to your Dakota Alert Sensors, your communications net, and pick up radio transmissions from unexpected signal sources, be them friend or foe, and on frequencies well known, or unknown. Double plus good stuff!

    Tech Tip:
    A quick and easy approach, that makes it easier for those with out a frequency list is to plug in the 2 meter ham band repeaters in your area, MURS, and Business band on the VHF side, and GMRS and FRS, plus any 70cm repeaters in your area, and set it to scan the list and use the Close Call option to monitor the UHF side if you do not have Murs Dakota Alert sensor using MURS channels, or if using the Dakota Alert Sensors without external antennas, monitor the VHF side. Program with the computer to have a back up, and to make the process easier. There are other way to configure it (set it up), but this a good start for most folks. Any frequency flashed on the scanners display is a Close Call signal, and should be recorded and added to the scanner list and investigated. Any signal that is nearby should be identified as either ‘friend or foe’, whether is a voice or a mic click.

    1. Forgot to mention, most scanners including this Uniden series, does not cover the entire spectrum that the now ubiquitous Baofeng UV5r covers. It does not cover 521-520Mhz, or the 220Mhz HAM band. Nor does it cover other military bands. Some older and higher end scanners do, yet often is forgotten is the 220Mhz Ham band. One can cover some of those loose ends with a bank of many scanners sharing a discone antenna, with a 20 dollar USB-RTL Dongle that covers most everything else. With the more expensive USB dongles, even drones can be identified. With the dongle, a poor man frequency analyzer, one can see weak transmissions even though they cannot hear them. And one can spot spurious transmissions, secondary harmonics, that can lead to the identification of those using the notorious Baofeng. Having a Baofeng or two, I’ve tested this.
