I have a Stryker 94hpc in my triaxle dump truck. Occasionally I will get a little feedback through the external speaker when keying up on 10 watts, but not on 4 watts (the two AM settings the radio has). Also won't get the feedback when the external is unplugged. The radio has a Palomar MAX-MOD transistor and I am using a Wilson 500 magnetic antenna and the SWR is under 1.5. The speaker is the correct ohms. When this happens I think I am hearing talkback too but I let go of the key real quick. Any ideas why this happens?
PS I have pretty much the same setup in my Jeep except the antenna is a Sirio 5000 and no max-mod transistor, never had a problem.
