Amateur Radio Station K7YVO
Current VHF/UHF transceivers are as follows:
The Yaesu FT-8900 is used for 24/7 operation of the APRS station in Digipeater/Igate modes and for net check ins. Uses a TinyTrak 4 TNC for computer interface and a 2 meter SlimJim antenna.
The FT-8900R is a ruggedly-built, high quality Quad Band FM transceiver providing 50 Watts of power output on the 29/50/144 MHz Amateur bands, and 35 Watts on the 430 MHz band. It includes leading-edge features like cross-band repeat, dual receive, VHF-UHF Full Duplex capability, and over 800 memory channels. And its 10-meter FM coverage brings the possibility of world-wide FM DX-ing to you on your drive in to work! Retail at $325.00
The Yaesu FT-2900 is used for 24/7 operation of the Winlink RMS Gateway station on 145.610 Mhz. This station is located in Sandy OR...Gateway to Mt Hood. Uses a Kantronics 9612+ TNC for computer interface and a 5 element vertical yagi antenna.
High power output with No Cooling Fan Needed, a huge, easy-to-read display, and one-touch WIRES™ Internet Linking Access capability are yours with the rugged new FT-2900R! 75 Watts of Solid RF Power with No Cooling Fan Needed! Four selectable power output levels are provided: 75/30/10/5 Watts. The power selection may be stored into memory, allowing you to conserve power while using strong local repeaters. Retail at $170.00
The Yaesu FTM-100 is used for my mobile voice and APRS operations.
The FTM-100DR's single receiver design provides 50 solid Watts of RF power on both the 144 and 430 MHz amateur radio bands, while still being host to a feature packed suite of both C4FM Digital and FM Analog communications capabilities that fit every amateur radio operators needs.
Designed with simplicity and convenience in mind, the FTM-100DR's highly visible and compact 160 x 40 pixel graphical dot-matrix display can be detached from the body of the radio and remotely mounted providing even more installation options. This vibrant white LED backlit display provides a clear and crisp view of the radios current operating status, not limited to GPS Information, SD Card status, and Operating band name/memory channel tags (Alphanumeric).
The FTM-100DR operates in three (3) Digital modes and an (1) Analog mode to suit your needs. This feature packed radio is our first Digital Mobile equipped with our new Automatic Mode Select (AMS) function that instantly detects the received signal mode. The AMS function enables stress-free operation and eliminates the need to manually switch between communication modes.
- V/D Mode (Voice/Data simultaneous communication mode) The digital voice signal is transmitted in one half of the band width. Simultaneously the other half of the 12.5 kHz band width channel is used for error correction of the voice signal and other data. By incorporating powerful error correction technology developed for professional communication devices, effective error correction codes provide the advantage of fewer interruptions to conversations. The Clear Voice technology developed for the C4FM FDMA Digital mode provides the ideal balance of error correction and sound quality.
- Voice FR mode (Voice Full Rate Mode) This mode uses the full 12.5 kHz bandwidth to transmit digital voice data. The increased amount of voice data permits high quality voice communication, providing superb sound quality for a “rag chew” with friends.
- Data FR mode (High Speed Data Communication Mode) This high-speed data communication mode uses the full 12.5 kHz bandwidth for data communication. The transceiver automatically switches to Data FR mode when transmitting snapshot pictures, and can be used to transmit large quantities of data at high speed.
- Analog FM mode Analog FM is effective when weak signal strength causes audio drop out in the digital mode, and enables communication up to the borderline of the noise level. Also the use of established Yaesu low power circuit designs provides greater efficiency than the digital modes. This is the typical FM mode used by most typical non-digital handhelds and VHF/UHF mobiles.
