Signal strength and readability report. A signal strength and readability report is a standardized format for reporting the strength of the radio signal and the readability (quality) of the radiotelephone (voice) or radiotelegraph (Morse code) signal transmitted by another station as received at the reporting station's location and by their ...
AN/PRC-10. The AN/PRC-10 is an American VHF portable radio transceiver, introduced in 1951 [1] as a replacement for the wartime SCR-300 set. The AN/PRC-8 and AN/PRC-9 sets are basically the same but cover lower frequency bands.

The procedural signs are distinct from conventional Morse code ...
In an FM two-way radio system, CTCSS encoder levels are usually set for 15% of system deviation. For example, in a 5 kHz deviation system, the CTCSS tone level would normally be set to 750 Hz deviation. Engineered systems may call for different level settings in the 500 Hz to 1 kHz (10–20%) range.
