I recently hooked up my base radio with my A99 on the chimney. It has been years since I have even looked at this stuff so please bare with me. I Have been talking along on my radio with a good SWR of about 1.2 on channel 1 and about a 1.4 on channel 40 for about a week or so. Well the other night my buddy and I were talking and I decided to try out the LSB on the radio. I flipped the switch and listened and got him tuned in. I keyed the mic and as soon as i spoke, the 3 amp fuse blew in the back of my radio. I replaced the fuse with a 2.5 amp fast acting, so not to hurt the radio, then turned back to AM. Now every time I key up and speak on AM the fuse blows. Does anyone have any idea what this may be? The radio has had channels put in it about 30 years ago. but other then that this radio is stock and in very good shape. I thank you for your help in advance.
