- 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
- united states - Whats the difference between national calling . . .
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)?
- 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
- What frequencies should I listen to for packet radio?
You could tune to 144 390 FM on a 2m rig and see if you can pick up some APRS This would require some software to decode packets (such as arpx for Linux) Just make sure you're not setting yourself up as a Digipeater until you find out what the network structure is in your area and whether there is a requirement at all National APRS frequencies: You should also be able to see APRS activity

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!

The noise persists at nearly full strength between 146 66125 and 146 67125 before completely dropping off Using directional finding we've isolated it to a large steam pipe in the basement
- callsign - Proper way to announce call sign at start end - Amateur . . .
I think I've heard both on 146 520 (But I need practice keeping track of callsigns) And just to round out the question, at the end of the conversation I've heard various ways of ending like "ABC123 clear", "ABC123", and more
