- Is the National Calling Frequency actually used?
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
- Why is there a repeater on 146. 46? Isnt that a simplex frequency?
3 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 input According to the ARRL band plan this is a simplex frequency How is this happening? I have complied and have quit using the radio
- Why can I connect simplex at 146. 52 but not at 145. 200 and 147. 000 . . .
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

- Calculating Antenna Length on the FCC Exam vs. in Reality
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
