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…
