Well, my long awaited ZBitx arrived 4 hours ago.? Put the batteries in, connected an antenna and was soon listening to lots of stations on 40 and 20 meters.? But when I tried to call out, no one responded.? I got a friend to tune up and listen.? I heard him clearly, he heard nothing when I transmitted.
?
I then tried a local receiver, and same thing but maybe worse:? I hear no audio when in TX but do hear a constant carrier on the receiver on the Zbits tuned frequency (this is in SSB Mode).? If I start shifting the receiver off frequency, I can hear some modulation products 1.5 kHz away, but nothing with useful readability.
?
The SWR and power meter on the Zbitx show power and low SWR, as does an external wattmeter.? The ZBitx also gets hot, so I know power is being made, but that power doesn't seem to be related to the tuned frequency.
?
One last item, as I got finally frustrated, I picked up the Zbitx while in TX and heard noise from the local receiver.? Tapping on the metal bottom produced some tapping sounds in the receiver.? But even that was inconsistent.
?
So, I suspect something is loose/broken in the new Zbitx.? I don't mind trying to troubleshoot, but I'd much prefer having a radio that works as anticipated, as I don't have infinite time to waste fixing someone else's problem.
?
Has anyone else had similar issues?
?
What do you suggest as remedial action???
