Alfonso Faustino: Super Heterodyne vs. Direct Conversion, and Front-end Transceivers

BLUF (Bottom Line Up Front): Your transceivers should be Super Heterodyne and have front-end filters (the ability to block unwanted RF) when in ICS-based emergency operations.  If you don’t get Super Heterodyne transceivers and don’t have a filter for the front-end, you will experience desensitizing in your transceivers while involved with ICS-based emergency comm operations:…

Alfonso Faustino: CARLA: Antenna Replacement Project (K6ASF)

Boss, N6MVT, invited me to go with him to one of the CARLA sites to replace an antenna on one of CARLA’s towers. I always enjoy helping Boss at his CARLA’s sites; because, I get to see all the technology that makes CARLA so great. In addition to CARLA’s technology, CARLA resides in some of…

Alfonso Faustino: Motorola XPR 7550 VHF Transceiver (K6ASF)

My collection of Motorola hand-held transceivers is complete with the Motorola  XPR 7550 VHF hand-held transceiver, shown below. The Motorola XPR 7550 VHF transceiver will take the place of my Motorola Radius CP200, as shown in the picture, below.  I will either sell or use it as a back-up for VHF communications. Since I already…

Alfonso Faustino: My code-plug of repeaters (K6ASF)

Since I transitioned to using Motorola transceivers, XPR 7550e (UHF), CP200 (VHF), and XPR 7580 (33-Centimeter), I have to do my best to ensure that each of these transceivers can provide me with the necessary coverage I need in the event of a catastrophe that knocks out the mobile phone services. By far, my XPR…

Alfonso Faustino: Motorola XPR 7580 Transceiver: 806-941 MHz (K6ASF)

An acquaintance gave me a Motorola XPR 7580, and his gift forced me to expand my knowledge and understanding of RX and TX operations in the 800 and 900 MHz frequencies with a hand-held transceiver.  As I mentioned in my previous BLOGs, I’m really a believer in the Motorola transceivers for emergency preparations and social…

Alfonso Faustino: Yaesu VX-6R: RX & TX:Aviation & Maritime Frequencies

LEGEND: For the sake of discussion for this BLOG, the word, transceiver, means hand-held transceiver. My Yaesu Submersible VX-6R was my very first amateur HAM transceiver; and, it has been one of the best purchases I ever made with respect to Yaesu products. For a HAM operator, this tri-band transceiver is reliable, durable, affordable, and has…

Alfonso Faustino: Aviation Transceiver: Yaesu FTA-450L

7-Sept-2017, 2217 Hours PDT When I travel, land, sea, and air, I carry either one, two, or three of these transceivers: Motorola CP200: Maritime Operations Yaesu FTA-450L: Air Operations Motorola XPR 7550e: Land Operations (though, I did program some UHF maritime and UHF aviations channels in this transceiver, as well — I like to have…

Alfonso Faustino: Motorola CP 200: VHF: Maritime Frequencies (K6ASF)

I only use four VHF frequencies — the rest of my HAM operational activities are on the UHF frequency band. So, what are the four VHF frequencies I use? MAR-09: Internship SAR MAR-13: Bridge Port-Bridge MAR-14: Bay Traffic MAR-16: DISTRESS (United States Coast Guard) As a PADI SCUBA diver, I am in the ocean about…

Alfonso Faustino: Reasons I use Commercial Hand-held Transceivers (Motorola XPR 7550e) versus Amateur Hand-held Transceivers (K6ASF)

Before I begin, I wanna thank HAM Operator, AKA: Boss, Tom (N6MVT), for introducing me to Motorola HAM operations: analog and DMR.  Thanks, Tom, N6MVT, for helping me program my Motorola and for introducing me to the wonderful world of CARLA.  Bottom Line Up Front: I use Motorola hand-held transceivers because I want the best in quality, durability, reliability,…
