14 Best Imgbb Alternatives 2025 146.520 mhz is the national calling frequency for fm voice. it's a "simplex" frequency, meaning that you call on this frequency and then listen for a reply on the same frequency. 39 on the 2 meter and 70 centimeter band plans published by the arrl, what is the difference in intended use between the calling frequencies (144.200, 432.10 mhz) and the simplex calling frequencies (146.52, 446.00 mhz)?.
Shutterstock 2311548187 Hosted At Imgbb Imgbb In 2024 Shutterstock I have a commercial ge phoenix transceiver that i sent out to be programmed on 146.460 but have been informed by a club that my transmissions are interfering with their repeater that has a 146.460. Example. 146mhz 300÷146=2.05 meters 2.05×39= 79.95 inches full length in inches. 79.95÷2= 39.95 inches 1 2 wave length in inches. 39.95÷2= 19.985 inches 1 4 wave length in inches. answer on test is 19. example 6m. meters already given. 6×39= 234 inches full wave length in inches. 234÷2= 117 inches 1 2 wave length in inches. answer on test. Just a note calling frequencies vary by region. 146.520 mhz is the 2m calling frequency in the fm mode in canada and the us, but not in most countries. be sure to check if you operate in other countries!. Have a look at the iaru region 2 band plan. most of the frequencies marked "all modes" or "dm" (digital mode) may be used for packet radio, although there does not seem to be a single designated packet calling frequency. normally a packet radio frequency is coordinated between operators in the area, since one frequency can be shared by several tncs. in this case the frequency is standardized.

In partcular, 146.52 is the 2m fm voice calling frequency and should not be used for digital modes like winlink. additionally, just because there is a standard list of frequencies doesn't mean you can just pick one and expect to get a connection. While programming my icom radio it has mr (memory)channels, vfo (variable freq) channels and call channels. what are call channels as comparred to memory or vfo channels? what is their use?. Center frequency 146.520mhz driven element is 1 8 wave 10.25" long set at 6.125" from the front. reflector element is 5 8 wave at 15.3" and 15.3" from driven element to the back. director element is 1 2 wave at 12.25" and set at the front. also, trying to figure out how to connect my so239. The power supply is an alinco dm 330mv. while studying for the technician exam i've been listening, mostly on 10 meters, and i've noticed an odd interference pattern every 145 146 khz i hear a steady series of beeps or chirps. i've hear them at 28.134 mhz, 28.280 mhz, 28.425 mhz, and 28.571 mhz.
