Hi everyone,
I recently finished mounting my BITX40 in a box and wiring up everything. The receiver works great, but I've got a couple of problems on the transmit side:
1) There appears to be a fair amount of carrier on the transmitted signal (confirmed by a friend about a mile away), at roughly the same amplitude as my audio. Is there a carrier null adjustment I can make? If so, how do I do it?
2) I also seem to have very low output power. My friend said the signal he was receiving from me sounded more like a half-watt than 5 watts, and when I hooked the rig up to a wattmeter, he was right on the nose - 1/2 watt out, and only when I really shouted into the mic (a standard computer mic/headset combo). At a normal speaking level, the meter barely moved. Does this suggest a problem with the PA? One note on the PA - I accidentally wired up the PA power line directly to the 12v input rather than the on/off switch, so it's powered up whenever the rig is plugged in. But I generally unplug the radio when I'm not using it, so it didn't seem worth the trouble to rewire it.
Comments or suggestions? Is there a mic gain control I can adjust? Suggestions for troubleshooting the PA?
