WLTC-FM Nautel NV15 Transmitter PA Module Cooling Fan Replacement – September 28, 2021
One of the six cooling fans on RF Module #1 in the WLTC-FM Nautel NV15 transmitter had failed. Along with the overall quality of Nautel’s transmitters, I particularly love the depth and breadth of the remote alarm and alert notification features included in their transmitters. In this case, I had received an automatic notification letting me know that fan #6 on RF module #1 had failed. I was able to remotely access and drill-down to the fan speeds and confirmed that fan #6 on that module was not running, showing “0 RPM” in the real-time metering. Before even going to the site, we had ordered and had the replacement fan in-hand, so I was able to get it diagnosed and perform the repair/replacement in a single trip. I like having that ability, and I’m sure the client appreciates the fact that it eliminated an extra trip to the site (around 3 hours of round-trip travel time plus on-site troubleshooting time) which equates to $$$ they get to keep in the bank.
