3-2 Memory Input
The TR-7800 has two different memories; normal memory and split channel memory (including priority
memory channel).
1. Normal memory (CH 0-12)
Example: To store 145.950 MHz ( — 600 kHz shift) in CH 5.
(1) Set the KEY/M.SEL switch to the KEY position (——).
(2) Set the MEMORY channel selector (16) to the CH 5 position.
(3) Input the frequency.
[DISPLAY]
Frequency before input
a) Press the [5] key (MHz digit).......
b) Press the [9] key (100 KHz digit).
c) Press the [5] key (10 kHz digit)...
d} Press the [0] key (1 kHz digit).....
(Simplex operation)
Note:
a. To input MHz digit, use the [4] and [5] keys.
b. When a wrong frequency is input by mistake, press the [C] key to clear the frequency.
The frequency display will indicate the frequency before input, Re-enter the correct frequency by pressing
the keys once again starting with the MHz digit.
c. When the 1 kHz digit key ( [0] – [4] ) is pressed. the frequency display indicates 0 .
When the ( [5]-[9] ) key is pressed, the display indicates 5.
d.
Do not press any other key unitill the correct frequency is input.
e.
The transceiver holds the previous frequency until the new frequency is input.
(4) Input the shift mode.
Press the [-] key (the indication changes from "S" to “-“).
(5) Store the frequency in the memory. Press the [M] key.
A tone will sound, indication data entry. Change the channel and input other frequencies in the same manner.
Note:
1. If you wish to change the shift mode from simplex. press the shift key of the desired mode.
2. When the transmit frequency is shifted ±600 kHz and it is outside the amateur band (144.000 ^ 145.995 MHz),
the transceiver operates in simplex mode.
2. Split channel memory (CH 13, 14)
Example: To store a receive frequency of 144.550 MHz and transmit frequency of 145.625 MHz in CH 14. proceed
as follows:
(1) Set the KEY/M.SEL switch (13) to the KEY position down.
(2) Set the memory channel selector (16) to CH 14.
(3) Input the receive frequency. Frequency before input:
a) Press the [4] key (MHz'digit).......... 4.
b) Press the [5] key (100 KHz digit).... 4.5
c) Press the [5] key (10 kHz digit).......
4.55
d) Press the [0] key (1 kHz digit)......... 4.550
Note:
For frequency input precautions, refer to "Notes" in normal memory.
