Hi livi, my name is John. Welcome to FixYa. If you have a MIC GAIN, turn it to MAX. If no avail, try a different mic. Are you saying you have no receive, turn the RF GAIN to MAX and the SQUELCH all the way to the left. Let me know. Thanks for choosing FixYa.....John
the up down is done differently in the magnum compared to the ranger. it takes a 22k resistor for making it to go up. and ground is down. cb shop temple, tx on yahoo search... do that and should work. its all done off ONE pin not 2 like the ranger
To tune frequencies in either 10 kHz or 100 kHz increments,
press the STEP button until the desired digit is
flashing. Rotate the FREQUENCY control in either direction.
The entire frequency range of the Magnum 257
can be stepped through in 10 or 100 kHz increments.
To tune in 1 kHz increments, press the STEP button
until the 1 kHz digit flashes on and off. Rotate the FREQUENCY
control. NOTE: When stepping in 1 kHz increments,
you are limited to tuning within a 10 kHz
Hello.I have a similar situation on a Magnum 257 HP operating on SSB (AM and FM works fine). If i Transmit it works fine, but when i release the Mic button (after TX), in the bottom side were the RX level should be, it appear somth like a signal level 3 to 5 (constant and continous), but i can't get any reception at all. Only if i turn the TX power level to MAXand i transmit, then it goes back to reception, but not every time. Somtime after TX i need to push the mic button 2-3 times to make it recive somthing, but this wors only if the power level is over 60-70% an i repeat, only on SSB.Can i get some help with this issue?
Yes, there is info there to do a complete alignment for the transmitter or receiver. I do have to wonder what caused the radio to develop the problem; like did it slide off freq all of a sudden, maybe was bought used with the problem in there? Or someone with that dreaded "golden" screwdriver? lol If the radio has a bad solder joint causing it to slide off freq, then just putting it back with the adjustment is just a band aid approach. Need to figure out what caused the problem, and go after that. I hope this sheds a little more light,, have a good one. Mechanic
