- Hello All, My ICE 419 bandpass filter has developed high SWR on 10 meters only!! I seem to recall there was a cap or two that went bad in some 419's... Any help or info on this would be very much app

- ICE 419 capacitor values are attached. In your case, it is probably the two 270 pf on the radio side (usually not the antenna side) that have failed. I recently replaced W7WW's 10 meter caps with thr

- For those of you wanting the ICE 419A capacitor values, you can download them here: http://www.mediafire.com/?pmsy1w4eh5c4nhy Make sure you read the handwritten note at the top. That link will expire

- I've had nothing but trouble with the two 419As I bought several years ago. I'm guessing that the caps are simply under-rated for dissipation, because it's common for them to fail with only 100W at 2

- I've never had a failure of my 419's, but plenty with my old Dunestars. One thing that can cause a lot of problems is running a tuner on your radio into a bandpass filter...especially if you have a b

- I run low power rtty contests with a dunestar 600 and an ICE419, 100watts heavy duty cycle. I have popped the caps on the 20M section in the ICE419 a couple of times. At least they are easy to get to

- I guess the only correct answer is to have an antenna tuner outboard of the amp thus, all equipment should see a proper load with minimal SWR. This is the way I run mine and have had no problems. The

- I have used Dunestar 600 band pass filters for many years. I have made tens of thousands of contacts using them running up to 150 watts and I have never had a failure. The manual clearly states to co

- I have not noticed any issue with the Dunstar except on the high end of 80m (75m) phone where the input SWR increases. I have not damaged a filter going up there (which only happens on rare occasions

- The owners manual for my Alpha specifically states to NEVER use the radio auto tuner when using the amp. Probably for the same reason. -- 73, Gary K9GS Check out K9NS on the web: http://www.k9ns.com
