I usually listen the channel first, to see if someone using, If someone is talking, wait or change the channel.
Then I go "This is <CALLSIGN>, name is <NAME>, from <LOCATION>, radio check, radio check"
and wait at least 15-20 seconds to repeat it, if nobody replies...

Welcome to new world of the radio communication.

There are few things related with antenna height at https://www.ecfr.gov/current/title-47/chapter-I/subchapter-D/part-95/subpart-A/section-95.317

Two things, came up my mind, you want to add to list
- Channels 8-14 to hand-held radios only
- Digital/data transmission is limited to 1 seconds not frequent than 30 seconds

Both MURS and FRS prohibit store and forward. That might be what you remembered.
Could you please let me know where in Part 95 it is written?
Thank you in advance.

GMRS is allocated 30 frequency channels in the range of 462 MHz to 467 MHz, which are divided into 22 simplex channels (where you transmit and receive directly) and 8 repeater channels (where you transmit to a repeater, which receives and re-transmits your signal on a different channel).
QuoteA repeater is a device that receives a signal on one frequency and re-transmits it on another frequency, thereby extending the range of the signal.
Generally, when setting up a frequency channel on a radio, we transmit and receive signals on the same frequency. However, for GMRS repeater channels, we set up transmit and receive frequencies differently; the difference between these two frequencies is usually 5 MHz. In some cases, such as yours, these frequencies may already be pre-set.
However, most repeaters require that you transmit a specific tone (often called PL, CTCSS, QC or CG) before they listen to your transmission. Therefore, you may need to set the tone value for the repeater channel you want to use.
