OK, It just may be because it's late on a Saturday night, but I am stumped.
I have a UHF 100W secure capable MSF5000 that when I key the TX (doesn't matter how of the GOZILLION ways) the 'PA On', 'PA Key' and 'PA Full' LED's light for a split second and then I get no power out. I am testing into my service monitor, so high ref. power is not an issue. I realize that the power control is a loop and I could be chasing my tail trying to figure out which came first - the lack of power or the lack of drive. I read in earlier posts something about JU1 being a service jumper. JU1 in this station is a 3 position header. When I change positions on that jumper, the station doesn't boot properly, gives an error, then resets. I don't think I am looking at the correct JU1. The manual eludes to many troubleshooting charts that apparently aren't in my book. I think that there were MANY authors and they figured that "someone else will write that." For those of you that know me and know what I do, I have never worked on anything this new. I'm used to the good ol' fashioned radios, where a strategically placed alligator lead fixed all your power-set ills. Even a "look at page xx in the manual for a troubleshooting flowchart" type message would be helpful. Scott Scott Zimmerman Amateur Radio Call N3XCC 474 Barnett Road Boswell, PA 15531
