QSY Function

The QSY function uses AFRS (Automatic Frequency Reporting System) to report a frequency on which voice

communications can be established. A station using the QSY function embeds the frequency information in a position

beacon transmission. A receiving station of this information can change frequency, or QSY, over to the reported voice

frequency to begin voice communication by the press of [TUNE] on the TM‑D710.

Transmitting QSY Information

AproperlyconguredfunctioningTM-D710QSYstationcanautomaticallyembedthevoicefrequencyfromthenon-data

bandtothebeginningofstatustext.InStatus5,“[FreqMHz]”isentered.Thisisthemechanismusedforautomatically

transmitting the frequency information. The format of the transmitted frequency is FFF.FFF MHz.

So, for example, if at the time of a beacon transmission, the non‑data band has a frequency of 446.100 MHz selected,

thenthefrequencyof“446.100MHz”getsembeddedtothebeginningofthestatustext.Ifyoucongureinanyof

Statuses1through4thefrequencyof“446.100MHz”atthebeginningofthestatustextmessages,thenthisxed

frequency will be transmitted as QSY information along with the beacon transmission. In addition to frequencies, there

areeldswhereyoucansendothersettingssuchasWide/Narrow,Tone/CTCSS/DCS,Shift(+/-),andOsetfrequency

simply by leaving one space between each value. Therefore, other information besides just a frequency can be sent.

QSY Information Format:

(InsertonespaceafterthefrequencybeforeenteringWide/Narrow,Tone/CTCSS/DCSandShift/Oset.)

• “T079”: An upper case “T” indicates Wide. Tone frequency of 79.7 Hz. (Encoding)

• “t079”: A lower case “t” indicates Narrow. Tone frequency of 79.7 Hz. (Encoding)

• “tOFF”: A lower case “t” indicates Narrow. Tone = OFF (Without any tone Encoding or Decoding.)

• “C079”: An upper case “C” indicates Wide. CTCSS frequency of 79.7 Hz. (Encoding/ Decoding)

• “c079”: A lower case “c” indicates Narrow. CTCSS frequency of 79.7 Hz. (Encoding/ Decoding)

• “D023”: An upper case “D” indicates Wide. DCS code of 023. (Encoding/ Decoding)

“d023”: A lower case “d” indicates Narrow. DCS code of 023. (Encoding/ Decoding)
