This is a brand new SL-30 that sends out carrier only no modulation. I've checked all the wiring, antennas and even swapped positions on my audio panel with my GNC 300XL. The unit receives, but the quality is unknown. The recommendation of the dealer is to wait till I'm on ships power, but the unit is rated 10-40 volts, and with my battery charged I'm showing 12.2 volts. When I key the radio it cuts off the modulation in my hangar FM radio.
I pulled the radio out of the plane and checked the antenna couplings on the back of the radio. Both the NAV and COMM show continuity from the center pin to the outside of the connector. This doesn't seem correct to me. I'm getting ready to send the unit back, but just want to make sure I've covered all the bases.
