I have a magnum s9 radio. the receive on FM mode has drifted, eg: i normally talk to friends on ch 31., freq 27.315. they all can hear me ok on this freq according to my freq display. but for me to hear them ok i have to adjust o 27.313/27.312. so i know its of a bit on the receive and would apprieate any help on how to fix the prob.
i know it would only be a slight tweek on a variable capacitor, but i dont know whch one.
the set seems to be ok an AM,and SSB, it is only of on FM receive.
Also a friend has a magnum delta force, but the wires for the signal meter have been disconnected from the pcb, can you tell me where to solder them onto.
Thanks very much and look forard to hearing from you

The Midland radio you have is NOT capable of FM transmit & receive. It is a Citizen's Band radio that operates on channels 1 thru 40 that are assigned to the 26.965-27.405 MHz frequency range. These are the standard 40 Ch CB frequencies in the U.S. (and may not be legal for use in other parts of the world without a license from your country's communications authorities). It also offers Weather Band reception - again these are US frequencies that may or may not even be used at all in the UK. Since the radio only displays a channel number, you don't actually know the frequency you're monitoring or transmitting on. Your friends on CH 5 may be in a completely different band.
Even if they are on the same frequency, the fact that they are operating in FM mode means that you would hear something - but it may not be intelligible - and the same would be for them listening to you transmit in AM mode. If you could have them switch their radio to AM, all would be fine. I suspect they use FM as there is much less static when compared to AM.
If they won't change to FM, you'll either have to stop trying to talk to them or buy a radio capable of FM (and make sure it has the same frequencies as theirs!).
the freq display can be different from the channel selector display. the crystal in the freqcounter maybe going out or just got out of alignment.... check it with a know accurate frequency counter to determine if its on fequency or not. 000 3174269649
