Have to use rf gain control to control volume. no control or very little with af gain control. ft101ee


RF gain is not used to control volume. It's used to adjust the sensitivity of the radio. If you have a station nearby that's very strong that you wish to listen to, turning down the RF gain will help reduce distortion and/or interference. The control for Volume is "AF Gain" (Audio Frequency Gain). You want to use it to set the volume level.

Magnum 257 6 digit display


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
frequency range.

Magnum 257 No Audio Being Transmitted


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?
