I've been using the Dunestar 600s for years at 60 to 100 watts throughput for
almost 20 years. They had some issues early on with caps frying for multiple
reasons. As with any of these bandpass filters, do not use an antenna tuner on
the radio side of the filters. This can put undue stress (voltage) across the
caps if there is a mismatch and will definitely blow them up. This includes
the tuner built into your rig. Never activate it if you are using BPFs.

Whats everyone using for low power rtty contesting?
Anyone using Dunestar and pushing 100w to them? How about the newer Hamation
419?
Or does everyone throttle back to 80-85w, or push 100w?
