Comments on: If a handheld ham transceiver is 144-430 MHz FM does that mean it is 2 meters and 70 meters? http://www.cq-hams.com/if-a-handheld-ham-transceiver-is-144-430-mhz-fm-does-that-mean-it-is-2-meters-and-70-meters/ New and Used Amateur Radio Equipment Thu, 27 Aug 2009 04:59:24 +0000 hourly 1 http://wordpress.org/?v=3.0 By: gary167 http://www.cq-hams.com/if-a-handheld-ham-transceiver-is-144-430-mhz-fm-does-that-mean-it-is-2-meters-and-70-meters/comment-page-1/#comment-180 gary167 Sun, 05 Jul 2009 12:16:23 +0000 http://www.cq-hams.com/if-a-handheld-ham-transceiver-is-144-430-mhz-fm-does-that-mean-it-is-2-meters-and-70-meters/#comment-180 If you think about a radio signal as a wave (called a sine wave). The wave length is the physical amount of space a radio wave would take from the peak of one wave to the peak of the next wave. In ham radio, we often refer to the band of frequencies in terms of meters. There is a calculation of: wavelength = 300 / frequency in MHz So the 144-148 meghertz band is roughly 2 meters. The 430-450 megahertz band is roughly 70 Centimeters (.7 meters) These lengths become very important when building radio antennas. The radio you are talking about has both bands avail to it.

The 430-450 megahertz band is roughly 70 Centimeters (.7 meters) These lengths become very important when building radio antennas.

The radio you are talking about has both bands avail to it.

It operates on the 2 meter band and the 70 Centimeter band. The 2 meter and 70 centimeter refers to the wave length.. The 2 meter band covers 144 through 148 Mhz (Megahertz) The 70 Centimeter Band covers 420 through 450 Mhz. Megahertz (A new word for Megacycles) is the frequency of operation. Most transceivers of this type will receive a wider coverage. The frequencies listed above are the transmit frequencies. Hope this helps :) This would be a dual band transceiver.

Do a search for your answer. If it's 144-430MHz, it will operate on all wavelengths between. Yahoo! is your friend. Do a search for your answer.

If it’s 144-430MHz, it will operate on all wavelengths between.
