| - | ** Detail of PA module ** | + | **Detail of PA module** |
| These radios (I've got two) don't have any thermal compound between the PA and heatsink so I liberally applied that horrid white Servisol paste to the PA and linear regulators. After holding the radio in transmit for a few minutes at full power the heatsink becomes appreciably warm, but not remotely hot - and the PA module is the same temperature so good thermal contact was achieved. After dialling back the RF power from 22W to 10W and leaving it in transmit for 10 minutes the heatsink had reached equilibrium and was ~40C with no forced airflow. At 10W the radio drew 1.6A at 12.2V, so that's ~10W thermal into the heatsink which it certainly appears appropriately sized for. | These radios (I've got two) don't have any thermal compound between the PA and heatsink so I liberally applied that horrid white Servisol paste to the PA and linear regulators.
