MAGNUM M-257 in Expanded Mode 
Instructions for use of Magnum M-257 in expanded mode. 
By 91DD018 Dave 
Frequency coverage 25.165mhz – 29.695 mhz 
 
Frequency coverage (includes all alpha channels) 
Band A 25.165 -25.605 
Band B 25.615-26.055 
Band C 26.065-26.505 
Band D 26.515-26.955 
Band E 26.965-27.405 
Band F 27.415-27.855 
Band G 27.865-28.305 
Band H 28.315-28.755 
Band I 28.765-29.205 
Band J 29.215-29.695 
 
If the radio has been left for more than two days with no voltage on the power leads, or 
the reset button on the programming board has been pushed, the memories will be lost 
and the radio will default to the following on the LCD display: 
 
 This is the default screen for the expanded mode. 
 
 
 
The radio has defaulted to channel 9 on the ‘E’ Band and the fifth number in the display 
ends in a 5. 
 
If you have not yet screwed the microphone in please do it now because there will be no 
sound from the speaker until you do! 
 
In the expanded mode we lose the split and repeater functions that are present when the 
radio is jumpered for 10 meters. 
 
Clarifier 
FM 09 E 5 
S/RF 
Step 1 Call 2 Scan 3
LCR 4 Mode 5 M load 
 
To move into frequency mode depress the clarifier button and release. The func sign 
should appear in the top left corner like below. 
 
 
 
With the Func showing momentarily press the call button….just once, don’t hold it. 
 
The display should change to the frequency for that particular channel and band. 
 
 
 
MODE Button 
To get out of FM mode hit the Mode button repeatedly to bring up USB. This button only 
works in one direction so from FM to LSB you have to hit it once for AM, again for USB 
and yet again for LSB. Hit it 4 times and you are back to FM 
 
Changing Bands 
The present position will enable you to scroll through the E band from 26.965mhz 
(Channel 1) to 27.405 mhz (Channel 40) in 10khz steps. 
 
To change bands hit the call button. The frequency will change and the letter E will also 
change to F then G and so on. Like the mode button this only works in one direction so to 
program the NZ CB call Channel frequency of 26.720mhz LSB we will have to press the 
call button 9 times to bring up band D 
Clarifier 
FM 27.065 E
S/RF 
Step 1 Call 2 Scan 3
LCR4 Mode 5 M load
Clarifier 
FM 09 E 5 
S/RF 
Step 1 Call 2 Scan 3
LCR 4 Mode 5 M load
Func  
 
 
The display should show as above. Rotate the channel change switch (Or press the 
up/down buttons on the microphone) so the channel readout shows 27.625 
Then press the step button once. The ‘5’ will blink. While it is blinking rotate the channel 
switch up or down till the last digit reads zero. Press the step button and the frequency 
display will revert to 26.720. 
 
 
 
 
Now when you rotate the channel switch you will scroll through the NZ CB frequencies 
in 10khz steps. If you live in NZ the best thing to do now is to put the call frequency into 
a memory so you can recall it with 2 clicks instead of 15. 
 
Memory Usage 
To place a frequency into memory follow the following steps: 
1. Press the clarifier so the func sign appears. 
2. Press M load 
3. Quickly press the button (1-5) that you wish to store the frequency in. 
Be quick after you press the ‘m load’ key. You only have a couple of seconds before 
it defaults back. 
To recall a memory just hit M-load and the button the memory is stored in and it will 
appear. You can scroll up or down from the memory frequency in 10khz steps. 
 
Clarifier 
LSB
26.720 D

Clarifier 
LSB
26.615 D 
S/RF 
Step 1 Call 2 Scan 3
LCR4 Mode 5 M load 
Hot Tip 
Store the Kiwi call of 26.720 LSB in memory. 
Store the Aussi call of 27.355 LSB in memory. 
Store the International DX call frequency of 27.555 USB in memory 
Store a frequency around 27.555 ending in 0 ie 27.540 USB in memory. This will enable 
you to check out the freeband frequencies ending in zero easily without having to use the 
step function. 
If you are active on 10 meters store a 10meter frequency as well so you can move around 
the bands easily and effectively. This is where this radio shines. You can quickly monitor 
up to 5 frequencies and start scrolling from any of them as required. 
 
Programing Tone 
This tone sounds each time the CPU is being programmed. It is helpful, in the beginning 
so you can be sure the command has been entered. You may eliminate the tone by simply 
pressing the PTT switch on the microphone and turning on the ON/OFF POWER switch 
at the same time. 
 
Microphones 
The supplied microphone is an electret type and the radio supplies +8 volts to the mic 
similar to ICOM radios. 
There is a trim pot in the microphone but adjust it at your peril. 
There are no off the shelf microphones that will fit this radio without reconfiguring the 
wires. 
 
 
……….Warning Warning Warning……… 
 
The Magnum 257 is a twin final radio and easily puts out 35 watts PEP on sideband. 
The output of this radio will fry most if not all transistorized CB amplifiers. The 
minimum amplifier to use with this radio is one with 4 transistors like a Texas Star 
TS500 or something with valves rated for 50-60w input. Do not use an amplifier with a 
driver stage like the TS667 because it will fry it also. The out put from this radio will 
drive an 8 (2SC2879) transistor amplifier to over 500W and a 4 transistor Amp to almost 
the same. 
If you are buying a linear specify high drive. 
This radio has fried a TS350HDV and a TS667V to date. 
Even if we turn down the mic gain to acceptable levels in SSB the radio transmits a full 
power spike on key down and key release that will get the amplifier transistors 
eventually. The power can be better controlled in AM and FM to allow use of CB amps 
in these modes but the risk is there regardless. 
It is better to get a bigger amp and drive it gently because it runs cooler and sounds sooo 
much better. Over driving is what causes 95% of all amplifier failures.
