[RTTY] bandpass filters

[k3mm at verizon.net]

 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?
