Hey guys... hope you all are staying warm in this bitter cold. (Where's all that "global warming" they promised us?) lol
Anyway, I've got a Cobra 29 LTD ST (SoundTracker) with an interesting problem:
The S/RF meter seems to work fine on RX but on TX, it doesn't register RF or CAL, it only registers SWR. If it is set to RF, when TX it just drops to zero. Same thing on CAL. However, if I switch it to swr, the meter WILL track (on TX) as I adjust the CAL knob.
Already checked the S/RF-SWR-CAL switch, the wiring, C81, R74, and VR5.
What else am I missing? Again, meter works FINE on RX when switched to the S/RF position; it just doesn't show TX watts (or swing on modulation) regardless of the VR5 setting.
Therefore, I don't think it's the meter. So... WHERE should I be looking NEXT? I'm thinking D10/D12????
Thanks guys!
