Been trouble shooting my SL-30 all weekend. Here's the problem.:
Com signals are in coming and out going but very weak. We used a hand held ICOM radio today to check that com is bi-directional. All intercom is good, mic gain good just very weak com traffic coming in and going out. The receptivity on the hand held is excellent but the SL-30 mounted in the bird right next to it is very poor. We thought it might be radio or wire harness but the work today proved the physical connections are good. We are looking closely at the coax and the antenna right now as the culprit. The antenna is a new Rami AV-17 bent whip. I checked the RF signal level on the radio and it ranges between 8 and 11. That seems very low to me but the manual did not state what the range should be? Anybody know from looking at your working SL-30? Also the COM noise level runs about 145 to 147. Again, not sure what the range "should" be but that sounded high???
Thanks guys,
